1.What Is A Case Sealer?

A case sealer is mostly used in packaging industry or industries where products are packed with sensitive care. A case sealer is basically a packaging equipment which is used to pack a carton or box in a highly efficient manner. A carton is placed on the conveyor and the tape rollers roll on both sides of the carton.

In this manner, the carton gets sealed from all the sides. A carton sealer ensures safe travelling of products even if it is to be delivered to a longer distance. This type of sealing reduces human efforts to a large level and also gives quality packaging.

2.What Are The Features Of A Case Sealer?

Features of a Case Sealer

1.Packaging Range

Case sealers are highly versatile that they provide a wide range of packaging standards. It can be customized to any range according to the length, width and height of the carton or box. No matter what material the box is made up of, a case sealer can seal it with high perfection and precision.

2.Power Supply

One of the most important features of a case sealer is that it does not require any special type of input power supply. It can be plugged in any of the range of voltage available in the global world.

3.Customized Conveyor Length

Another feature of a case sealer is that it is not utilized for only a single length box or carton. The input conveyor and whole system can be adjusted according to the packaging box. The conveyor speed and movement is also controlled according to that particular situation.

4.Structure

Most of the case sealers are made up of stainless steel due to which they are highly durable and last for a longer period. The environmental condition does not harm the sealer that much due to its composite body structure.

5.Speed

Last but one of the unique features of a case sealer is their speedy packaging. The rate of products sealed in a prescribed time is much higher than done by traditional sealing methods. This increases the productivity of an industry and also allows producing number of carton in an hour without any human effort.

3.What Are The Benefits We Can Get From a Case Sealer?

Advantages of a Case Sealer

1.Increasing Productivity

Case sealers are used to increase the productivity to a large level which was near to impossible with traditional methods. Manual sealing takes a lot of time whereas automatically and within a minute a case or carton gets sealed with perfection. It directly increases the production rate on daily basis.

2.Avoiding Material Wastage

Using a case sealer ensures that all sides of a box are proper and evenly sealed so that no material wastage takes place. A single strip is continuously applied on the whole case which also avoids multiple times application of tape. In this way the applied tape is also saved.

3.Proper Sealing Position

Previously, an excess quantity of taping on sealed cartons was received. But now using a case sealer, tape is applied on proper positions within a system and no excess tape is used. In this manner sealing with efficient length and position is done.

4.Product Security

A single layered sealing on cartons with consistency allows the product to be highly secured. It ensure better security of products no matter how far it has to travel. A case sealer decreases pilferage rate and increase security of products during transportation.

5.Product Presentation

The product which is packed in a case sealer is highly presentable in nature. It is packed in a level that the customer gets directly attracted to it and wishes to have a case sealer

6.Less Damage to Products

Using ordinary means of sealing like scissors, staplers, straps or glue has high probability of product damage. These cannot completely secure the product and in a result both worker and products loss can occur. Case sealer on the other hand provides unbreakable sealing to case so that the product and its surrounding both get secured. Also the repairing cost reduces to a distinct level while using a case sealer.

7.Operators Safety

As the product gets secured, it reduces the chance of any accident with its motion. The employee or operator that carries the carton is completely safe and there is no chance of any injury to the operator. A case sealer also reduces human efforts, fatigue, injuries and also machine breakdowns.

4.In Which Industries These Case Sealers Are Mostly Used?

Applications of a Case Sealer

Packaging Industry

Case sealer is most popularly used in packaging industry where large numbers are to be packed in limited time. Traditionally, this method was done by the operator himself but it was much time consuming and also the packaging was not done in a proper manner. Case sealer has now provided packaging industry a great benefit in clean packaging of products.

Other than packaging industry, all industries that pack their products in cartons or boxes are now focused on using these case sealers for their packaging process. Case sealer increase productivity in an exponential manner and helps industries to become more economically stronger.

5.What Is the Working Principle of a Case Sealer?

Working Principle of a Case Sealer

The working principle of a case sealer is not as complex as other sealing options. It only follows the few procedures.

Initially all the products are kept inside the carton or box and then sent to the conveyor of a case sealer.
All external and internal parameters including power, conveyor speed, tape rolling speed and other are maintained for proper sealing.
The carton is then placed on the conveyor manually and then it automatically travels to the path towards the machine.
As the carton enters the sealing area, both up and down tape sealing rollers roll on the surface of it and seal the carton from upside down.
The motor then drives the carton out of the system and in this way the sealed carton is received at the end of conveyor system.
In this simple procedure, highly efficient sealing is performed on carton with precision and accuracy.

6.What Are The Types Of Case Sealer Available?

Types of a Case Sealer

Carton sealers are primarily available in two types. These types are then further divided according to the construction of machine and its application. The two types of case sealers are

Semi-Automatic Case Sealer

In a semi-automatic case sealer, both human and machine interface are present and different stages. Initially the carton is placed by the operator and flaps all the interfaces either minor or major. Then the carton enters the system and tape sealer is applied. Also after the sealing application the carton is manually received at the other end.

Fully Automatic Case Sealer

While in a fully automatic case sealer, all the procedures are performed by the machine itself. Sometimes the operator only places the carton on the entrance if the machine is isolated from the rest procedures. Otherwise, the whole product placement, flapping of carton edges, sealing, and quality check all are done by the machine itself. Also a proper conveyor system allows the entrance and exit of cartons.

7.What Are The Main Components Of A Case Sealer?

Components of a Case Sealer

The main components present in a case sealer are

Tape Dispensers

This is the heart of a case sealer because it holds the main sealing tape in it and dispenses over the products. The tape dispenser rolls over the carton when it is feeded to the system. The important feature of a tape dispenser is that it only releases a desired amount of tape according to the size of carton.

Tape dispensers are available in different width and sizes ranging from 25mm to 100mm for an overlap tape of up to 70 mm

When the tape overlap is 50mm,the tape width is 30mm,tape range is 25-30mm.When the tape overlap is 50 or 70mm,the tape width is 50mm,tape range is 38-50mm.When the tape overlap is 70mm,the tape width is 100mm,tape range is 65-100mm.

Pillars

Pillars

Pillars are the one which forms the assembly of a case sealer. They are of different size and width according to their placements. They are also incorporated with air cylinders and gas springs.

Tape Alarm

Tape alarm is an indication unit that monitors and supervises the process of sealing. This system monitors the knife and roller movement with its photoelectric eyes. Whenever some mishap or warning occurs, the tape alarm generates an alarm both in audio and video form. In the mean time it also holds the rest of process. It indicates following warnings.

If the roller tape gets empty.
If the roller tape is about to get empty
If there is no tape on the roller
If the tape is not properly cut and the roller still pulls out tape.

Motors

For ensuring the movement of cartons or boxes and also properly sealing, some motor driven units are their which are moved using motors. Also the conveyor system is moved using these motors.

Conveyor System

Conveyor systems are there in a case sealer machine for proper in and out of a carton or box. These conveyors make easily delivery of boxes to the system and also inline the system.

8.What Are The Common Faults and There Remedies That Are Faced In A Case Sealer?

Common Errors and their Remedies in a Case Sealer

Some of the possible errors that are faced in a case sealer are

Insufficient Sealing

The most popular error or fault that is faced in a case is of insufficient application of sealing. Due to this the packaging is not proper done and hard kneading or peeling is present which can further crack the sealing in transportation. This factor mainly arises because of the improper setting of parameters like temperature, pressure, conveyor speed and etc.

This error can be removed if proper sealing pressure and conveyor is maintained and synchronized with each other.

Edge Breaks

Another problem faced in case sealer is of shrinks or edge breaks. This problem is created because of improper sealing temperature.

The error can be rectified if the sealing temperature is maintained according to the product and tape material that has to be packed.

Wrinkles Formation

Wrinkles are formed due to the failure of sealing that is caused by static electricity. As the result case sealers applies tape with wrinkles and also the inward attraction of contents takes place.

Properly static electricity supply can minimize this problem.

Product Contamination

There are possible scratch marks or ways that can contaminate products due to improper cleaning of parts that are present in a case sealer.

Proper parts clean schedule if done will reduce the chances of product contamination.

9.Which Factors Are Necessary To Be Noticed Before Buying A Case Sealer?

Factors that are Necessary to be noticed Before Buying a Case Sealer

There are eight important factors that should be kept under consideration before going for purchasing a case sealer

1.Versatility

The most important factor before selecting a case sealer is to check its versatility and compatibility. Because it is not necessary that only a single sized carton is to be sealed every time. There can be different sizes according to the situation. So, the manufacturer should select the machine after complete study of whether it is compatible on uniform size or also on random sizes.

Random case sealer can give lot of productivity and economical advantage to the manufacturer. It is always a good decision to select a random case sealer rather than a uniform case sealer.

2.Weight of Case

The weight handling capability of a case sealer should also be one of the important concerns for the buyer. As the products that are being packed vary in weight, it can directly affect the speed of conveyor. As a result of it poor quality taping will be performed. So, select the sealer with maximum weight bearing capacity according to production setup.

3.Productivity

Productivity is always a prior factor for any industry. A more productive machine can drastically increase the productivity of any industry. So, the case sealer should be selected keeping the present and future production capacity in mind

4.Labor Involvement

Machine with high automation can reduce the labor cost and also increase the production cost. So, machine should be selected keeping in mind that is the labor necessary or not or fully automated machines are required

5.Size of Case

Case sealer in which the industry is interested to invest should be compatible with small to large cartons. Size is an important factor which ensures that the machine will seal number of cartons regardless of their sizes.

6.Working Environment

Another important factor for considering in a case sealer is that in which environmental conditions the industry will use it. Environmental conditions can directly affect the structure of a case sealer. As in high humid conditions, case sealer made up of stainless steel are more preferred.

Likewise in normal working conditions, simple enameled steel body structured case sealer can be used. While checking the environmental conditions, machine size and its placement should also be considered according to the area available within territory.

7.Authenticity of Manufacturer

An industry should have a complete look on different manufacturers rather than sticking on one. In the current conditions, many manufacturers are busy in making case sealers so it’s better to go through all those authentic manufacturers which are more popular among large scale industries. Customer reviews can also help in selecting best suitable machines.

8.Local Assistance

Having local assistance is always a plus for any buyer. It helps in complete machine installation and also ensures quick availability whenever required. Local suppliers also support in technical issues which can directly reduce long machine stoppages.

Tablet is a preparation made by mixing a drug and excipients from compressing.

Tablet is a compressed medication in the form of a disc. It is usually coated with sugar or some other compound to delay the release of the drug into our system. They are less expensive to manufacture and are accepted by most people.

From the outside, capsules and tablets are actually easy for you to distinguish.

2. What Are the Main Types of Capsules and Tablets?

In your daily life, when you get any capsules or tablets, could you distinguish their types and functions?

Main Types of Capsules and Tablets -photo credits: singlecare

Main Types of Capsules:

Capsules can be divided into hard capsules, soft capsules, enteric-coated capsules, etc., and are generally used for oral use.

Capsules can mask the bad smell of drugs, avoid the destruction of drug components by gastric acid and pepsin, improve the stability of drugs, and improve the bioavailability of drugs.

Hard Capsules: It refers to the preparation of a certain amount of medicinal powder or auxiliary materials into uniform powder or granules, which are filled into hollow capsules.

hard-capsules

Hard Capsules -photo credits: capsugel

Soft Capsules: It refers to a capsule made by processing liquid medicine or liquid-solid medicine into a soft capsule material.

Soft-Capsules

Soft Capsules -photo credits: health

Enteric-coated Capsules: These refer to hard capsules made of granules or pellets coated with enteric materials and filled in capsules.

When taking capsules, the temperature of the water should not be too high. If the temperature is too high, the capsule shell with gelatin as the main raw material will be softened or even destroyed, which will affect the bioavailability of the drug in the body.

Taking-capsules

Taking Capsules -photo credits: pbleiner

Therefore, capsules should be taken whole and not taken apart, especially slow-release and controlled-release capsules.

If the capsule shell is peeled off, the drug will be suddenly released, absorbed too quickly, or even cause adverse drug reactions.

Main Types of Tablets:

Tablets mainly include ordinary tablets, chewable tablets, coated tablets, effervescent tablets, dispersible tablets, soluble tablets, controlled-release tablets, multi-layer tablets, and oral tablets.

The dosage of the tablets is accurate, the quality is stable, the transportation and storage are convenient, and the patients are more convenient to use.

Regular-Tablets

You need to add the dispersible tablet to water to disperse and drink it. Can also be chewed or taken. The more common drugs are cefaclor dispersible tablets.

Sustained-release-or-controlled-release-tablets

Sustained-Release or Controlled-Release Tablets

Sustained-Release or Controlled-Release Tablets: This is a type of tablet that controls the rate at which the drug is released to prolong the action of the drug.

Sustained-release tablets or controlled-release tablets have the advantages of stable blood drug concentration, fewer doses (conducive to the elderly with poor memory), and long treatment times.

Unless otherwise specified in the instructions, controlled-release tablets cannot be taken apart.

Sustained-Release-Tablets

Sustained-Release or Controlled-Release Tablets

If the formulation is broken apart, the controlled release membrane or matrix will be destroyed. The drug will be released quickly, thus failing to achieve sustained release and long-acting purposes.

It is also possible that due to the release of the drug, your body absorbs a large amount of it in a short period of time, causing poisoning and adverse reactions.

Multilayer-Tablets

Multilayer Tablets -photo credits: fette-compacting-parts

Multilayer Tablets: This is a tablet that consists of two or more layers. It is generally made by pressing twice or more. Each layer contains a different drug or excipient.

This avoids chemical changes between the different drugs in the compound formulation or achieves the effect of slow-release and controlled-release. The tablet should be swallowed whole.

Sublingual-Tablets

6. What Are the Differences Between Capsules and Tablets?

The differences between capsules and tablets, in addition to appearance, content, production methods, and their respective advantages are different.

Different Forms

Capsules are usually capsule shells containing some powder, granular, or oil medicines, while tablet medicines are ordinary medicines without special packaging.

Advantages of Capsules

One of the advantages of capsules is the solid dosage form of liquid medicines, that is, medicines with high oil content or liquid medicines that are difficult to be made into tablets are made into soft capsules, which have the characteristics of convenient use and clear dosage.

The hollow capsules used to encapsulate drug particles are a kind of special pharmaceutical excipients, which are equivalent to containers for medicines.

Although the hollow capsule itself has no curative effect, it is beneficial to improve the stability of pharmaceutical preparations and help the fixed-point release of the main drug components.

At the same time, it can cover up the unpleasant taste of the drug.

After oral administration, the capsule will wrap the medicine and enter the human digestive system together, and will eventually be absorbed by the human body, so the quality and safety of the capsule are also directly related to the quality of the medicine.

oral-administration

Oral Administration of Medication -photo credits: nursecepts

Capsules have the advantage of being easier to swallow and faster delivery time than tablets.

While tablets are less expensive than capsules, capsules are capable of mixing more sensitive medications because the container is an important oxygen barrier.

Disadvantages of Capsules

If the contents of the capsule are bulky, the capsule will be larger. It also has a short shelf life.

Advantages of Tablets

The dissolution rate and bioavailability of tablets are better than capsules.

The quality is stable.

Tablets are dry solids, and some drugs that are susceptible to oxidative deterioration and deliquescence can be protected by coatings. Therefore, light, air, moisture, etc. have less influence on it.

The body is easy to digest and absorb for you.

Disadvantages of Tablets

Tablets have weaker dissolution and consumers have more concerns about those than capsules.

Tablets are cheaper and easier to dispense a dose, but they don’t release the drug into your system as quickly as capsules.

Different Medicinal Properties

The particles in the capsule may irritate the esophagus and gastric mucosa and may also be inhaled into the trachea, so it needs to be loaded into the capsule to determine the stability of the medicinal properties and reduce damage to body organs.

Tablets are usually prepared as solid preparations that can be taken directly with water, which can reduce damage to gastrointestinal tissue.

Taking Tablets with Water -photo credits: medcline

Different Efficacy

Capsules and tablets are both taken with warm water. Remember, they may be directly digested and absorbed in the mouth, which may lead to loss of efficacy.

tablets-taking

Tablets Taking -photo credits: pharmaceuticalmanufacturer

However, capsule substances can usually reduce the damage to gastric mucosal stimulation, and need to enter the gastrointestinal tract before they can be dissolved and absorbed, and directly exert better efficacy.

Preparation Technology

The capsule preparation process is relatively simple, mainly filling the drug in the capsule shell, which is mostly made of gelatin, so the capsule can be quickly dispersed, dissolved, and absorbed in the gastrointestinal tract.

The tablet is compressed and formed under the impact of mechanical pressure, and there are many excipients in the tablet, which affect the dissolution and absorption of the main drug.

Drug-Preparation

Therefore, capsules of the same drug will work faster than tablets, not that tablets do not work.

After knowing so much about the differences between capsules and tablets, you will be better able to make better choices for your needs in the future.

7. What Is the Absorption Rate of Capsules and Tablets?

When medicines are consumed by you, they are first dissolved and absorbed. Some capsules and tablets will dissolve in your stomach first. Some capsules and tablets will dissolve in your intestines. However, their absorption rates are different whether in your stomach or in your intestines.

From the point of view of absorption speed:

Drug-Absorption-and-Bioavailability -photo credits: basicmedicalkey

Solid preparations such as capsules and tablets are mainly taken orally.

After administration, the drug needs to be dissolved and then absorbed through the gastrointestinal epithelial cell membrane into the blood circulation to play its therapeutic role.

Oral-Administration-of-Drugs

Oral Administration of Drugs -photo credits: pharmapproach

Oral preparations absorbed rates are generally in the order of capsules > tablets.

In addition, the drug in the capsule is filled in the capsule shell in the state of powder or granules, which is different from the tablet and does not need to undergo a process such as mechanical extrusion, so the capsule generally takes effect faster than the tablet.

From the point of view of disintegration time:

Disintegration and Dissolution -photo credits: frontiersin

Hard capsules can be completely disintegrated within 30min; soft capsules and enteric-coated capsules can be completely disintegrated within 1h.

The ordinary tablet disintegration time limit is 15min;

Dispersible tablet, the soluble tablet is 3min; the sublingual tablet, the effervescent tablet is 5min; the film-coated tablet is 30min;

Extract tablet, sugar-coated tablet, and enteric-coated tablet is 1h.

Dissolution and disintegration -photo credits: researchgate

All in all, capsules are prepared into powders, granules, small tablets or pellets, etc., and then filled in the capsule shell. Compared with tablets, the production cost is relatively high.

For budget considerations, the generic pharmaceutical company will prefer tablets over capsules.

In general, the absorption rate of capsules is much better than that of tablets. However, tablets are cheaper.

8. What Are the Characteristics of Capsules and Tablets?

There are significant differences between capsules and tablets in terms of odor, absorption, and drug release.

Odor

Capsules: They can mask the bad smell of medicine and improve the stability of medicine.

capsules-3

Capsules -photo credits: pharmaceuticalmanufacturer

The medicine is packed in a capsule shell, which can be isolated from the outside to avoid the influence of light, air, and moisture, and has a certain masking protection and stabilization effect on the medicines with bad odor and instability.

tablet-coating

Tablet Coating -photo credits: pharma knowledge

Tablets: During the tablet production process, there is also a coating added to the tablets. The coatings are divided into sugar coatings or film coatings.

The sugar coating of the tablet can mask the bitter taste of the tablet; the film coating can mask the bad smell of the tablet and make it easier for you to take.

film-coating

Absorption

Capsules: They can make the drug work quickly in the body.

body-absorption

Body Absorption -photo credits: youtube

Drugs are filled into capsules in powder or granular form. Compared with tablets and pills, there is no influence of mechanical pressure during preparation, and it can be rapidly dispersed, dissolved, and absorbed in the gastrointestinal tract.

Tablets: Tablets are solid preparations in the form of flakes or special-shaped flakes, which are uniformly mixed with drugs and excipients and compressed.

excipients

Excipients -photo credits: innovationcompounding

Because a number of excipients are added to the tablets, and after compression molding, the dissolution rate of tablets is slower than that of powder and capsules, which sometimes affects their bioavailability.

Drug Release

Capsules: It can delay or localize drug release.

The medicines are made into granules or pellets, and suitable coating materials are selected according to your needs, and then packed into capsules, so that the medicine has the effect of slow release and prolonged effect.

drug-release

Drug Release -photo credits: freepik

Enteric-coated capsules allow the localized release of drugs in the small intestine. There are also controlled-release capsules that release the drug slowly and at a constant rate in a prescribed medium.

Tablets: They also can delay or localize drug release.

Because the outer layer of the tablet is sugar-coated, film-coated, or enteric-coated the medicine also has the effect of slow release and prolonged effect.

Tablets-4

If you cannot accept the strong taste of the medicine, then we strongly recommend the capsule form for you. If you find capsules difficult to swallow, tablets are a better choice.

9. Why Are Capsules and Tablets Made into Different Colors and Shapes?

If you have enough life experience, you will find that different capsules and tablets come in different shapes, colors, and sizes. And there are reasons for these differences.

Distinguish

The color and shape of capsules and tablets facilitate differentiation between drug varieties or doses to ensure that drugs are not mixed up during manufacture and use.

capsule-options

Especially for those patients who need to take more than one medication a day, it can reduce their medication errors. Especially elderly patients, often remember the appearance of the drug (color, shape), not the name.

Patents

Some drug manufacturers register the appearance of their products (including size, shape, color, texture, and aroma) as patents as property rights under trademark law, known as “trade dress”.

tablets-with-marks

Tablets with Marks -photo credits: pharmaexcipients

You can even identify specific drug names based on their appearance. Generic drug manufacturers are not allowed to copy the shape, color, and size of these branded drugs.

Especially for new drugs, manufacturers try different drug names, colors, and shapes to avoid repeating other drugs.

medication-pills-in-different-shapes

Medication-pills in Different Shapes -photo credits: audiocardio

Many capsule shells or the sugar coating of the tablets are marked with the relevant numbers and numbers.

Stability

Different drugs have different physical and chemical properties, such as different sensitivity to light. Drugs that are unstable to light can be protected from light by using dark coatings or capsule shells.

Flavoring Effects

The sugar coating on the outer layer of the tablet can play a role in correcting the taste, and different colors are set for the sugar coating in order to distinguish.

But capsule shells are generally tasteless. The capsule shell component is refined from medicinal gelatin or starch and auxiliary materials.

Moisture Proof

The moisture-proof effect of the capsule shell is much better than that of the sugar coating.

So in your daily life, what shape and color of capsules and tablets do you prefer?

10. How Are Capsules and Tablets Made?

Due to the large demand for drugs, most of the capsules and tablets in the world are produced by fully automatic machinery. This can not only ensure the demand for large production volumes but also improve production efficiency and production safety.

Capsule Filling Machine

A Capsule Filling Machine is a kind of equipment used to fill empty capsules with pharmaceutical ingredients.

Two Common Packaging Methods-Shrink Packaging VS Vacuum Packaging

Shrink Packaging Machine

Two Common Packaging Methods-Shrink Packaging VS Vacuum Packaging

As a fact,there are two common packaging methods in the market-shrink packaging and vacuum packaging,if you always go to the supermarket,maybe you will find that some products are respectively packaged by these two different packaging methods.

But,have you really thought about the two packaging methods?Why some products are shrink packaged while others are vacuum packaged?What are the differences between them?Which one is suitable for your demand?Now please explore the answers from this article.

Add a header to begin generating the table of contents

1.What is shrink packaging VS vacuum packaging?

At the first part,we need to resolve the basic problem,what is shrink packaging and what is vacuum packaging,in other words,what are the definitions of them.

Shrink Packaging

Shrink packaging is to wrap product with a plastic film which is accord with the size of it,then begin the operation of heat-sealing,under the influence of the heat,plastic film is shrinking constantly until it fit tightly to the surface of product.

Shrink packaging originated in the mid-1960s and developed rapidly in the 1970s,it is widely used by some economically developed countries.

Vacuum Packaging

Distinct from shrink packaging,vacuum packaging is to extract the air from the container of product,to make it under a low-oxygen condition in which microorganism can not survival and reproduce.

The appearance of vacuum packaging is earlier than shrink packaging,it first appears in the 1940s,and after 1950s,it has developed in a fast speed.

2.What are the effects of shrink packaging VS vacuum packaging?

In the basic case,the purpose of shrink packaging and vacuum packaging is to storage products for longer time,and besides,they also have other effects,which are as follows:

Effects of Shrink Packaging

Moistureproof and Waterproof

Because of the leakproofness of shrink packaging,you can ensure that there is no moisture inside the packaging film,therefore,shrink packaging is moistureproof and waterproof.

Anti-pollution

Through shrink packaging,the products are sealed in plastic films so they will not contact with dust in the air or other environmental elements,as a result,shrink packaging achieves the function of anti-pollution.

Avoid Shock

In fact,when the product is stuck, the plastic film which is wrapped around it can plays a role in buffer,protects the product to a certain degree.Moreover,if the product which is shrink packaged is a fragile object,the film can prevent splashes when the product is broken.

Effects of Vacuum Packaging

Prevent food oxidation

Sometimes,there are some fatty foods,they contain a lot of unsaturated fatty acids,which are easy to influenced by oxygen and come to oxidation.Vacuum packaging extract the air,so it can effectively avoid food oxidation.

Prevent Pollution

The reason why vacuum packaging can prevent products from pollution is that,by using vacuum packaging,the products is wrapped in the packaging pouch and don’t touch outside environment,so possible pollution is avoided.

Keep a Good Appearance

The same as others,principle of this is also because vacuum packaging can keep food in a low oxygen condition,which inhibits the survival and reproduce of the microorganism,so that the food can keep in a original appearance.

Crush Resistance

During the vacuum packaging,after extracting the air, there are other gases filled into packaging pouch,then the air pressure in the pouch is greater than the air pressure outside the pouch, which can effectively prevent the crushing deformation of the food and does not affect the appearance of the pouch.

3.How many types of shrinking films and vacuum packaging pouches there are?

In general,there are different types of shrinking films and vacuum packaging pouches,which are made of different materials and are adapted to different products.

Shrinking Films

PE Film

This kind of film is suitable for wine, cans, mineral water, all kinds of beverages, cloth and other products of the whole collection packaging,it takes advantages of flexibility and tear resistance ability.

In addition,the PE film is hard to be damaged and the shrinking percentage of it is high.

PVC Film

The PVC film has features of high transparency,high glossy and high shrinking percentage.

POF Film

POF refers to multi-layer co-extruded polyolefin thermal shrinkage film,it has high surface gloss, good toughness, high tear strength, uniform thermal shrinkage.

OPS Film

OPS film is type of shrinking film which is standard to the environmental protect requirements,it has high strength, high rigidity, stable shape, and has good gloss and transparency.And the OPS film is convenient in processing,coloring and printing.

Pet Heat-shrinkable Polyester Film

This film is stable under normal temperature,but while the temperature up to glass transition temperature,it starts to shrink.It has many advantages,and the most special one is that there is no renaturation of it, which makes it has a certain anti-counterfeiting function.

Vacuum Packaging Pouches

Aluminum Foil Vacuum Pouch

The material of this vacuum pouch is generally PET/AL/CPE or PET/NY/AL/CPE,This product has good performances such as anti-static, oxygen, shielding, moisture-proof, shading function and excellent heat sealing.

Aluminum foil vacuum pouch is widely used in food, electronics, chemical and other industries. Because the raw material of aluminum foil itself is expensive, the cost of vacuum will be relatively high.

Nylon Co-extrusion Vacuum Pouch

Nylon co-extrusion vacuum pouch is made of PA, EVOH and PE, PP, TIE and other resins.It has the characteristics of pollution-free, high barrier,low cost, small capacity ratio, high strength, flexible structure and so on,and it makes the production process of food packaging materials realize pollution-free.

Nylon Composite Vacuum Pouch

The material of nylon composite vacuum pouch is similar to nylon co-extrusion vacuum pouch,the difference between them is the technology,the composite pouch is made up of multiple layers of materials.

PE Vacuum Pouch

PE vacuum pouch is the most widely used vacuum pouch in the market because the price is cheap,that is,high cost performance.But,it has disadvantages of high breathability and low leakproofness,as a result,it’s easier to be broken.

4.What are the pros and cons of shrink packaging VS vacuum packaging?

Certainly,nothing in the world is perfect,both the two packaging methods have their own pros and cons,which will be explained in detail to the below.

Pros of Shrink Packaging

Adaptable

As is mentioned above,shrink packaging to heat the film which is cover around the product,then it is wrapped tightly to the products,so that it is adapted to products of various shapes and sizes.

Transparency

The film which is around the product is transparent,so people can directly see the appearance of the product,which is convenient for purchase.

Stable

The close and tight contact between the film and the product can increase the stability of the product,prevent it from moving position.

Save Labor

Both the packaging technology and packaging equipment of shrink packaging are simple,which makes it convenient for shrink packaging realizes automatically production,save the investment of labor.

Cons of Shrink Packaging

Can Not Be Recycled

One of the cons of shrink packaging is that it is hard to recycle,as the shrink packaging is to tightly wrap the product itself,the recovery rate is relevantly reduced.

Not suitable For Heat Sensitive Products

If there are some heat sensitive products,shrink packaging is not appropriate for them.So,in fact,shrink packaging isn’t suitable for all kinds of products.

Energy Consumption

In addition,the precondition of shrink packaging is heat,to reach the required temperature,there is much energy that consumed.

Pros of Vacuum Packaging

Retain the Original Taste

Vacuum packaging can make sure that food is sealed in packaging pouch,it will not contact with air,so it can keep the same condition as when it is packaged.As a result,the taste of food is also retained.

Save Space

Vacuum Packaged products are compact and organized,when you put them into your refrigerator or other places,they will not occupy too much space,in other word,vacuum packaging can save your space.

Reduce Cost

By the way,vacuum packaging can reduce the cost which you spend in packaging food or other products because its packaging procedure and raw material are simple.

Convenient

Similar to the last point,the whole operation process of vacuum packaging is more simple than shrink packaging,it doesn’t have so many complex procedure,so vacuum packaging is convenient.

Cons of Vacuum Packaging

Not Environmental Friendly

Generally,vacuum packaging uses disposable packaging pouches,which are unfriendly to the natural environment.

Easy to be Affected by Temperature

Although vacuum packaging can lengthen the shelf life of food,it often thanks to the help of refrigerator,if food is exposed to the high temperature condition,it still be affected.

Not Adapt to Liquid

There are a few kinds of liquid such as beverage and milk can be vacuum packaged,but when it comes to soup or congee,it seems not so convenient to operate.

5.What is the application range of shrink packaging VS vacuum packaging?

Even if both shrink packaging and vacuum packaging are suitable for many fields,they also have their own applications.

Application Range of Shrink Packaging

Food Industry

Shrink packaging is always used to package food,you will find shrink packaged food in supermarket,fruit store,bread store and so on.

Beverage Industry

The application range of shrink packaging in beverage industry is also wide,shrink packaging can make the packaging film fit the beverage product perfectly,so it is widely used in beverage industry.

Medicine Industry

Furthermore,shrink packaging is also used in pharmaceutical industry,the outside package films of medicine bottles and medicine cases are shrink packaged.

Commodity Industry

Actually,shrink packaging is also used in commodity industry,such as shampoo,shower gel,facial cleanser,toothpaste, detergents and so many other commodities.

Stationery Industry

And,stationery can also be shrink packaged,for instance,look at the picture,the notebook uses shrink packaging.

Express Transportation Industry

If you always shop online,this is not strange to you,sometimes,the carton package that you receive will also have a shrink film on the outside,this can reduce some shock to the cartons.

Cosmetic Industry

Maybe ladies are not unfamiliar with this,generally,cosmetic or skin care products all have a layer of plastic film packaging to cover their packaging cases.

Application Range of Vacuum Packaging

Food Industry

The most basic application of vacuum packaging is the food field,you can say that it is mostly widely used in this industry.Vacuum packaging is used to pack meat,vegetables,fruit,snacks,etc.

Medicine Industry

Vacuum packaging is also widely used in medicine industry,its function is to protect drugs from environmental affects,keep the property of drugs and lengthen the shelf life of medicines.

Electronic Component Industry

Vacuum packaging applied in electronic components industry,to prevent the components from being damaged by statics.

The all above is the main applications of shrink packaging and vacuum packaging,of course that these are not the whole application range,the applications of shrink packaging and vacuum packaging is large more common than you can image.

6.What is the working principle of shrink packaging VS vacuum packaging?

After reading the all above content,I believe that you have a general understand of the two packaging methods,the next part is to tell you the working principle of them.

Working Principle of Shrink Packaging

In detail,the working principle of shrink packaging is that,heating the shrinking film at a high temperature, the irregular arrangement of atoms has undergone drastic changes.

Then under the use of infrared radiation light, plastic molecules move again, the arrangement changes, so that through atomic rearrangement, resulting in a large reduction of the area of the film.

In this way, it can more closely fit the finished products to be packaged and processed by the manufacturer, that is the working principle of shrink packaging.

Working Principle of Vacuum Packaging

The working principle of vacuum packaging is simple,it solves the problem from the origin.At first,you need to consider,why does food go bad?The chief culprit is microorganism,it is because of the survival of microorganism that the food would be mildewed,however,what if microorganism disappears?

Vacuum packaging achieves this,the survival of microorganism depends on oxygen,so we extract the oxygen of the packaging pouch,means that the microorganism loose its survival condition,it can not survive and multiply,so the function of vacuum packaging is realized.

7.What is the technologicalprocess of shrink packaging VS vacuum packaging?

Besides the working principles,you also need to know the technological process of shrink packaging and vacuum packaging,that is,how does a shrink package or vacuum package create.

Technological Process of Shrink Packaging

There are two types of shrink packaging method:manual shrink packaging and mechanical shrink packaging.

If you choose manual shrink packaging,you need to wrap the product with film by hand,and then use heater blower gun to blow hot air on the product to complete the shrink packaging process,but this method consumes too much time and energy,so it just suitable for family needs.

On the contrary,the mechanical shrink packaging is to assist the help of shrink packing machines,process of this shrink packaging method is also simple,just divided to two steps:wrap in advance and heat shrink.

The first step,you need to wrap the products with plastic film,and leave the necessary seam for the heat shrink step.And then is the next step,put the wrapped products on the heat shrinking equipment,when the heating starts,the film begins to shrink until it closely fit the product.

Technological Process of Vacuum Packaging

Vacuum packaging needs to use vacuum packaging machines,although there are many types of vacuum packaging machines,their working process is similar.The whole packaging process can be divided into three parts:extracting out air,filling into other gases,hot-sealing.

At the beginning,put product into the chamber of vacuum packaging machine,then the machine start work,extract the air of the packaging pouch until the vacuum index in the pouch is up to requirement.

After this step,the machine fills other gases such as nitrogen, carbon dioxide, rare gas and other single gas or a mixture of two or three gases into the packaging pouch,to guarantee that the pouch is under the positive pressure,which makes the product hard to be damaged.

The final step is hot-sealing,the chamber inflates and the hot pressure frame presses the mouth of packaging pouch to complete the hot-sealing operation.Until now,vacuum packaging process is finished.

8.What are the similarities of shrink Packaging VS vacuum packaging?

Even though shrink packaging and vacuum packaging are two different type of packaging methods,they also have some similarities,which are to the below:

Transparency

In common,either shrink packaging or vacuum packaging uses transparent films or pouches to package products,this is one of their similarities.

Heat-sealing

During the packaging process,both shrink packaging and vacuum packaging have a heat-sealing step to ensure the products are sealed into the package.

Neat Packaged Appearances

Moreover,products which are shrink packaged or vacuum packaged all kept in a good and neat appearance,they looked compact,clean,exquisite and beautiful.

Widely Used in Food Packaging

The most similar point of shrink packaging and vacuum packaging is that both of them are widely used in food packaging field because they can make food keep fresh.

9.What are the differences between shrink packaging and vacuum packaging?

Certainly,when there are similarities,there are differences,now lets start to explore the differences between shrink packaging and vacuum packaging.

Thickness of Packaging Material

As is known,the packaging material of shrink packaging is plastic film while vacuum packaging uses packaging pouch,in many cases,the packaging pouch maybe a little thicker than plastic film.

Packaging Machine

It is mentioned a little bit in the previous article that the two packaging methods all have their own packaging machines:shrink packing machine and vacuum packaging machine,the two types of packaging machines have different function and working process.

Presence of Oxygen

The most essential difference is the presence of oxygen,shrink packaging uses high temperature to realize heat-sealing,it doesn’t affect by whether there is air,on the contrast,vacuum packaging needs low oxygen,it has a high requirement of vacuum.

That is the most obvious distinction of shrink packaging and vacuum packaging.

10.Which one is better-shrink packaging or vacuum packaging?

After reading all above text,you may find that the shrink packaging and vacuum packaging have their own advantages and disadvantages separately,you can not absolutely say which of them is better,how about just say which one is better in specific situations?

When you need to pack liquid product,it is better to put the product in proper container and use shrink packaging cause vacuum packaging isn’t suitable for all kinds of liquid products.

When you need to pack products which is in a large size,such as furnitures,cartons,or even larger objects,it seems hard to find packaging pouches in such a large size,in this case,shrink packaging is a better choice.

If you need to pack products which are sensitive to high temperature,choose vacuum packaging is better,the reason is that the process of shrink packaging is in a high-temperature condition,may cause damage to this type of products.

And there are some products which will release toxic substances when they are under high temperature,it is obviously you can not use shrink packaging to pack them,vacuum packaging is better in this situation.

Of course that there are many other situations,you need to consider the real condition,choose more proper one of the shrink packaging and vacuum packaging.

Conclusion

Totally speaking,both shrink packaging and vacuum packaging are useful and convenient for your daily life,you can choose each of them according to your actual requirement.After reading this article,if you still have some confusions,welcome to contact us.

Multifunctional Pulverizer: The Complete Buying Guide in 2025

Multifunctional Pulverizer

Multifunctional Pulverizer: The Complete Buying Guide in 2025

A multifunctional pulverizer is a machine that uses to pulverize large-sized materials into the desired size items and this process of grinding is called pulverization. During pulverization through this equipment, an external force has been applied to crush the materials.

In the year 2023, the multifunctional pulverizer has numerous applications in different industries including agriculture, food industry, manufacturing industries, landscaping, pharmaceutical industries, printing, recycling, etc. This can be used for all kinds of materials either it is wet or dry. Before buying it, several questions arise in our mind related to its proper functioning and based on its cost. This article would be helpful to resolve queries that arise during buying of a multifunctional pulverizer, here we discuss.

Add a header to begin generating the table of contents

1.What is Multifunctional Pulverizer?

A multifunctional pulverizer is a machine used to crush sawdust, waste materials from the furniture factory, wood chips, the cotton stalk, cornstalk, the beanpole, the peanut shell, wheat straw, and others. It is also called slimmer, it has various advantages as it can be used for simple material, although its operational principle is also stable, and have a good pulverizer effect. After pulverization, the crushed materials can easily be released from the crushing compartment of the multifunctional pulverizer.

During pulverization, the external forces exerted on materials, include:

Shearing

The shearing is suitable for crushing fibrous, tough materials and large stones, it has applications in coarse crushing and crushing.

Impacting

The impacting is mainly suitable for crushing brittle materials and it is usually used in crushing work.

Rolling

The rolling is used mainly for each type of material and is applied for high-fineness and ultra-fine pulverization.

Grinding

The grinding is mainly for ultra-fine and for super-large pulverization machines, which can be further pulverized.

Nevertheless, in the real crushing method, many external forces are applied at the same time. These machines are mainly customized based on high-end crushers.

2.What are the Different Types of Multifunctional Pulverizers Available on the Market?

In fact,the multifunctional pulverizers can be divided into four main types,which include tabletop pulverizer machine,portable pulverizer machine,multipurpose dry and wet pulverizer and industrial pulverizer.

Tabletop Pulverizer Machine

Tabletop pulverizer machine,as the name implies,it is designed compact and small enough to be put on tabletop,very convenient to carry and operate.It always be used to grind products such as rice,wheat,chop,millet, pepper and so on.

The working principle of this type of pulverizer is quite simple,the materials are feed into the machine through the hopper,and then be delivered into the chamber,in the chamber,the materials are repeatedly beaten by the hammer until they become smaller particles or powder.

Portable Pulverizer Machine

Portable pulverizer machine is used to pulverize materials which is sticky,it is widely used in pharmaceutical,chemical,food industries,etc.

The working principle of portable pulverizer machine is friction between different gear discs,the machine is equipped with a moveable gear disc and a fixed gear disc.Once the machine begins working,the two gear discs impact and rub with each other,under the pressure and friction,the materials are pulverized.

Multipurpose Dry and Wet Pulverizer

This type of pulverizer machine is the most universal,it can work in a high speed,constantly grind,crush or pulverize materials,whether the materials are wet or dry.It can be used to pulverize a variety of materials such as food,spice,sauce,poultry feed and others.
The working principle of multipurpose dry and wet pulverizer is similar to that of portable pulverizer machine,they both take use of friction of different gear discs to pulverize materials,the difference is that the multipurpose one can pulverize more types of materials in a higher speed.

Industrial Pulverizer

The industrial pulverizer,is the most large one among the four types of multifunctional pulverizer,it is used for industrial applications.This machine is suitable for minerals, chemicals, spices, grains, herbs,etc.And its production capacity is excellent,it can pulverize a large amount of materials one time.

The working principle of industrial pulverizer is that,the materials are feed into the machine from the feed hopper,and then flow to the chamber,and after that,the hammer will constantly hit the materials to pulverize them.

3.What are the Differences between Grinder and Pulverizer?

In a certain degree,the grinder and pulverizer have common function,although the two types of machine have some similarities,they also have many differences,in this part,you will figure out the differences between them and have a deeper knowledge.

1.What Is A Vacuum Feeding Machine?

A vacuum feeding machine is the most ideal, improved and new invention of modern technology that is employed to deliver bulk materials such as powder, granules, pellets, flakes, and many other small particles. Through dust-free close pipe it generates fast conveying process ensuring zero environmental pollution.

Moreover, its modular design enables the quick connection of vacuum loader with other bagging machine and assures the damage free flow of fragile items during transport.

2.How Does A Vacuum Feeding Machine Work?

A vacuum feeding machine works by the predetermined procedure that is sequencially explained below in detail:

The initial process starts when vacuum pump creates negative pressure inside the vacuum housing while bottom valve is closed. Through inlet modular air is sucked from the pipeline connected with feeding station which generates the airflow and ultimately starts the movement of particulate material.

The vacuumed air produces swirling motion of particles which adheres to the filters fitted upward in vacuum suction feeder and accumulates all the depositing material in separating containers/filters.

At same time, air shocks are produced by tanks each connected to a filter and completely separates the gas, dust and raw materials. When the required transport time is realized the vacuum pump switches off, the valve of hopper is opened and material is delivered to receiving vessel through the hose of hopper. The air compressor immediately cleans the filters and the same process goes on in rhythm until it is desired.

3.What Are The Key Components Of A Vacuum Feeding Machine?

Some of the major components which together form the structure of a vacuum feeding machine are mentioned below:

Vacuum Pump

It is the main part of any vacuum feeding machine which produces the false air in order to accelerate the movement of materials present in machine.

Air Compressor

This component of machine plays an essential role in providing neat, safe and healthy environment for goods’ processing. When the load is released from hopper air compressor quickly clean the filters with back flow pulse.

Control Device

Another core part of vacuum feeder is the control system which enables you to set the parameters like product amount, time and flow of air required for material operation. Once you have fixed the measurements, machine will take the instructions and work automatically.

Product Intake

It is the product feeding station where bulk materials are loaded before their transportation for operation. Material can be directly entrained from this plant into vacuum feeding suction.

Suction Tube

This tube is either made up of flexible plastic or stainless steel whose function is to sucked the air. Eventually the air grabs loaded material from feeding station and move it towards vacuum conveyor.

Ball Valve

It is located inside the suction tube which helps to adjust the amount of air by increasing or decreasing its level.

Transport Line

Transport line is the bridge between feeding station and actual vacuum conveyor. It consists of the vacuum-tight pipeline through which items are transferred to inlet modular of vacuum feeder.

Receiving Vessel

Receiving vessel is usually a container placed under the hopper of vacuum feeder. When the material is passed through complete procedure the contamination free products are then delivered to receiving vessel.

7.Explain In Detail The Types Of A Vacuum Feeding Machine?

A vacuum feeding machine can be divided into two major types. Every vacuum feeding machine is either dilute phase or dense phase. To know both of them well look into the comprehensive details given below:

Dilute Phase Vacuum Feeding

Dilute phase feeding refers to the process of conveying particles by using high velocity and low pressure. The method of dilute phase is essentially continues due to which it is most commonly used. It needs relatively large amount of air to feed less amount of particles.

Working Principles

This method of vacuum conveying is very common and starts with the loading of powder. The powder is diluted in pipe line having low volume. The transported material looks like cloud due to high distance. After cleaning material, the vacuum feeder processes it and release for final discharge by opening the valve.

Components

The components of a dilute phase vacuum feeding machine includes pressure blowers, vacuum pump, rotary airlock valves, beam cooling, extracting valve, dust filter and bin vents, material piping, cyclone separators and storage vessel etc.

Types

Dilute phase feeding consists of two types; positive pressure feeding and negative pressure. Positive pressure operate above atmospheric pressure, having low cost and suitable for powders. Negative pressure process with air below atmospheric pressure, having high cost due to complex components and best for hazardous substances.

Advantages

This system of conveying is highly flexible and easily handle the processing of various material. It has simple operational system and is cost economical. Parts can be easily disassembled for cleaning.

Disadvantages

High velocity and air volume consume more power. Not suitable for abrasive material because the constant high speed transportation of these materials can cause pipe wear. Fragile or friable products may deformed or crushed during the process.

Application

Due to high air pressure this method is good for processing powders, non-fragile and hard products. Industries including cement, flour and chemical are taking the services of this machine.

Dense Phase Vacuum Feeding

Dense phase vacuum conveying is the process where large amount of bulk material is processed using low velocity. This method is efficient as it take dense volume of particles. Its main principle is to slow down the velocity so as to avoid the stage where material may break or degrade.

Working Principles

The process initiates after switching the machine on. The air is entered into transport line where low power of air is required to process bulk material. Mostly, it is liquidized for continuous and smooth flow. The particles are filtered and delivered to containers below the hopper.

Components

It consists of supply vessel, motive gas device,line charger, clean gas piping, filter, inlet valve, vent valve, transporter and plant air supply.

Types

Types of dense phase feeding can be divided on the basis of their function like:

The first one is fluidized dense phase which prevent the spaces between particles and good for processing material like soap powder, fly ash, limestone etc. Another one is low velocity slug flow, it is good for friable granules such as sugar, wheat, milk powder and peanuts etc. Next is extrusion flow, which convey products with pipe full of material. For feeding meat lumps for canned animal food, chopped fish chunks and gravy etc.

Advantages

Due to low velocity it reduces the chances of material slip thus increase the level of efficiency. The particles do not abrade conveying and avoid wearing it. It consume less air, eventually would require small air-solid separation devices.

Disadvantages

Dense phase feeding system is more expensive compare to dilute phase feeding system due to its specs of components. To know the process of dense phase feeding certain level of qualification is required which make if difficult to operate the machine. Often, particles are liquidized for smooth flow but this causes mess as water goes down the line.

Application

There is no such limitation on the type of product that has to be processed by dense phase vacuum feeding. Instead, it can process multiple items like soft, hard and especially abrasive substances because of its high bulk density. Most of the nuclear industries, chemical, food and medical industries are looking for using this machine.

8.Differentiate Between Dilute Phase Vacuum Feeding And Dense Phase Vacuum Feeding?

A vacuum feeding machine can be categorized into two main types on the basis of its possible feeding conditions. How each is different from another is what we have clarified below:

No	Factors	Dilute Phase Vacuum Feeding	Dense Phase Vacuum Feeding
1	Definition	In dilute phase feeding, particles are delivered with high air speed through continuous process	Where as a vacuum feeding machine conveys particles in batches with low air velocity it is called dense phase feeding system
2	Process	Its process is simple with loading material from feeding station in form of suspended particles	It is little bit difficult to operate and need proper expertise. However, it takes the material in bulk with low velocity
3	Speed	Its conveying power very fast but deliver less amount at a time	This process is gentle and slow in nature due to low air pressure but convey large amount of bulk material
4	Suitable Material	It can harm fragile items thus is only ideal for material with low density and hard structure	It is material friendly and never damages brittle materials
5	Abrasive Material	It can be dangerous to feed electrostatic material by dilute phase	It is suitable for processing abrasive material and do not create any electric charge
6	Capacity	Its capacity of conveying is extremely high and can reach up to 10TPH	Due to reduced air tension dense phase delivering capacity is lower than 10TPH
7	Cost	Construction of dilute phase feeder is typically less expensive due to light duty work	It is more expensive with heavy duty components
8	Example

9.What Are The Common Problems And Troubleshooting Of A Vacuum Feeding Machine?

Vacuum feeding machine is highly effective equipment for transporting variety of materials. However, few problems may arise during the process which can be resolved by knowing underlying troubleshooting:

No	Problem	Solution
1	Vacuum pump pressure is higher than normal and particles are escaping from line	There may be product build-up problem or leakage in elbow. Recover the coupling line and plugged convey lines
2	The filters and bin vents are fluctuating with inconsistent pulses	Bags are dirty or solenoid is bad. Replace inspecting filter bags and diaphragm
3	Sudden blockage in pipeline	It may be due to heavy load or low air pressure. Maintain the velocity of air and fix particular rate for feeding so that material can be easily passed through pipeline
4	Particle degradation problem occurs during feeding	Friction against pipeline can create break in friable material. To prevent this make sure that air pressure is low and use dense phase feeding for fragile items
5	Material become sticky and leads to condensation	The reason can be temperature change due to which particle absorb moisture. To solve this, trace the heating part and adjust proper air blowing

10.What Should Be Considered Before Buying A Vacuum Feeding Machine?

While purchasing a vacuum feeding machine you must have to be vigilant enough and stay alert to consider some of the important aspects such as:

Nature of Products

What type of material you are assuming to feed either it is fragile or strong, free flowing or cohesive, these all questions matters a lot. Same as, for soft and easily broken material dense vacuum feeding machine is best suitable for retaining their sterility like that of medicines. While on other hand, for hard material dilute phase vacuum feeding machine is good.

Material of Construction

Before choosing any automation solution it is very important to know what its texture is tailored with whether stainless steel, carbon steel or pharmaceutical sanitary grade. By looking properly into it can relieve you in processing variety of materials due to higher degree of energy efficiency and solid build-up.

Machine Features

Do you know the features of vacuum feeder which you are considering to purchase it? Like what is its upstream process? Is it coming from hopper, feeder or reactor? The airflow direction and size of vent, fans, and filters these all can influence the feeding of your products so make sure they are ideally equipped and compatible to your needs.

Velocity of Feeding Rate

How much volume a vacuum feeding machine can deliver per hour is another crucial factor to know. So make sure that its rate of conveying is up to the mark.

Type of Process

Usually, feeders are of two types; volumetric and gravimetric. Volumetric feeders process material in batches without exact measurement and are less expensive. If you just want to feed the products this is better applicable. While as, items which requires high accuracy level with continuous processing are in need of gravimetric feeders.

Headroom above Process Equipment

Find out how much headroom is available in machine. It is the compulsory space for processing because even smaller vacuum feeders require at lead 30″ headroom.

Conclusion

A vacuum feeding machine has brought automation in feeding industry due which it has been recognized globally with super-fast and safe performance. Allpack is the leading supplier of vacuum feeding technology for more many years. If you are eager to know more about this machine, feel free to ask.

9. What Is the Working Principle of a Food Vacuum Packaging Machine?

Sealing Process Table

The main function of the food vacuum packaging machine is to remove oxygen, which is beneficial to prevent the food from spoiling.

The working principle of the food vacuum packaging machine is relatively simple.

Because food spoilage is mainly caused by the activity of microorganisms, and most microorganisms (such as molds and yeasts) require oxygen to survive.

Food-Vacuum-Packaging-Line-Chain

Food Vacuum Packaging Line Chain

Vacuum packaging uses this principle to remove the oxygen in the food in the packaging bag, so that the microorganisms lose the environment for survival.

Experiments have shown that when the oxygen concentration in the packaging bag is less than 1%, the growth and reproduction speed of microorganisms will drop sharply. When the oxygen concentration is lower than 0.5%, most microorganisms will be inhibited and stop multiplying.

Oxygen Content Table

(Note: Vacuum packaging cannot inhibit the reproduction of anaerobic bacteria and the deterioration and discoloration of food caused by enzymatic reactions, so it needs to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high-temperature sterilization, irradiation sterilization, microwave sterilization, salt pickled etc.)

In addition to inhibiting the growth and reproduction of microorganisms, another important function of vacuum oxygenation is to prevent food oxidation.

Because oily foods contain a lot of unsaturated fatty acids. Unsaturated fatty acids are easily oxidized by the action of oxygen, thus making the food taste bad and spoiled.

Carbondioxide-Content-Table

Carbon dioxide Content Table

In addition, oxidation can easily cause the loss of vitamin A and vitamin C. The unstable substances in food coloring are exposed to the action of oxygen, darkening the color.

Therefore, oxygenation can effectively prevent food spoilage.

In addition to the function of oxygenation and quality preservation, vacuum packaging mainly has the functions of anti-pressure, gas resistance, and preservation. This can more effectively keep the original color, aroma, taste, shape and nutritional value of the food for a long time.

In addition, there are many foods that cannot be vacuum-packed, but must be vacuum-inflatable packaged. Such as crunchy and brittle food, and food that is easy to agglomerate and easy to deform and lose oil; food with sharp edges and corners or high hardness that will pierce the packaging bag, etc.

Potato-Chips-Vacuum-Packaging-Machine

Potato Chips Vacuum Packaging Machine

After the food is vacuum inflated, the inflation pressure in the packaging bag is stronger than the atmospheric pressure outside the packaging bag. This can effectively prevent the food from being crushed and deformed under pressure, making the appearance of the packaging bag more beautiful.

The vacuum inflatable packaging is filled with a single gas such as nitrogen, carbon dioxide, oxygen, or a mixture of two or three gases after vacuum.

Among them, nitrogen is an inert gas, which plays a filling role to maintain a positive pressure in the bag. In this way, the air outside the packaging bag can be prevented from entering the bag, which has a protective effect on the food.

Nitrogen-Vacuum-Packaging

Nitrogen Vacuum Packaging

Carbon dioxide can be dissolved in various fats or water to form carbonic acid that is less acidic. This carbonic acid can effectively inhibit the activity of microorganisms such as mold and spoilage bacteria.

Oxygen can inhibit the growth and reproduction of anaerobic bacteria, and can maintain the freshness and color of fruits and vegetables. High concentrations of oxygen keep fresh meats bright red.

12. Why Does the Vacuum Packaging Machine Leak Air During Packaging?

Air-Leaking-of-Bad-Sealed-Packaging-Bag

Air Leaking of Bad Sealed Packaging Bag

There are many reasons why the vacuum packaging machine cannot be vacuumed cleanly. The main reasons are: the vacuuming time is too short. The vacuum pump is aging or not properly maintained.

The vacuum studio is not well sealed, and there is air leakage when vacuuming. The power of the vacuum pump is too small and the actual pumping speed ratio does not match, and the vacuum cannot be fully pumped.

The solution is as follows:

You should prolong the vacuuming time.

You should replace the vacuum pump, and pay attention to maintaining and replacing the vacuum pump oil timely.

If the vacuum pump has not been maintained for a long time, you should first clean up the waste oil in the vacuum pump before replacing it.

(Generally, the first maintenance is after the vacuum packaging machine has been working continuously for 300 hours.

After that, the maintenance will be carried out after the vacuum packaging machine has been working continuously for 500 hours.)

Proper-Operation

Proper Operation

You should check the vacuum chamber for leaks. If there is an air leak, you must replace the sealing strip in time.

If the vacuum pump is too small to achieve the desired vacuum effect, you need to replace it with a higher-power vacuum pump.

After the mechanical equipment is bought and used for a period of time, you must pay attention to its maintenance.

Just like a car, it needs regular maintenance. If maintenance is not in place, no matter how good the equipment is, it cannot be used for a long time.

13. How Long Can Vacuum-packed Food Generally be Stored?

Vacuum-packed food can generally be stored for about 1 to 12 months. The storage time varies depending on factors such as the type of food and the processing before packaging.

Different types of food after vacuum packaging have different storage times at room temperature.

In general, fresh agricultural products or lightly processed meat products can be kept at room temperature for 2 days. But after vacuum packaging, it can be extended to 6 days, and some can be extended to 18 days.

Vacuum-Packed-Fresh-Agricultural

Vacuum Packed Fresh Agricultural

Dried fruit vacuum-packed food can be stored for a long time, even more than twelve months.

Storage Time Table

Cooked vacuum-packed food will keep for a shorter period of time. Typically, it stays fresh for around 15 days in winter and spring. And in summer and fall, it will only keep for about 4 days to about a week, but preferably needs to be refrigerated.

14. How to Vacuum Pack Food With Liquid?

At present, the most common vacuum packaging of pure liquids on the market is Tetra Fino Aseptic, which is what we see as boxed milk. This is the vacuum packaging of pure liquids.

Tetra-Fino-Aseptic

Tetra Fino Aseptic

When the food with soup is vacuum packed, you can choose a liquid vacuum packing machine. This machine is provided with a groove. This allows the liquid to sink without spilling during vacuum packaging.

There is a double-chamber concave liquid vacuum packaging machine and a rolling vacuum packaging machine. By adjusting the angle of the machine, a certain angle of inclination can be created to prevent the soup from spilling.

15. Can You Eat the Leaking Vacuum-packed Food?

Vacuum-packed-greens

You would better not eat food that is leaking air.

It is best for you not to eat food that leaks air, because the vacuum packaging is for the purpose of preventing air from entering, preventing oxidation, and preventing corrosion.

If the vacuum packaging leaks, it proves that the air enters, so the items may deteriorate.

Inflatable packaging is generally filled with nitrogen and carbon dioxide, which can protect fragile food and prevent corrosion.

Once air leaks, the food will be oxidized with the air, and it is likely to deteriorate.

If the air leaks for a long time, it is impossible to judge whether the food is edible or not. It is likely to cause symptoms of abdominal pain, bloating, and diarrhea.

Similarly, food that has no air leakage but has expired is also inedible.

16. What Should You Do When Choosing Food Vacuum Packaging Bags?

Food-Vacuum-Packaging-Bags

Food Vacuum Packaging Bags

The outer packaging of food vacuum packaging bags needs to be marked with text. Label the factory name, factory address, and product name. And the words “for food” should be clearly marked.

Products are accompanied by a product inspection certificate after leaving the factory. This food vacuum packaging bag is relatively safe.

Colored vacuum bags (dark red or black, etc. currently on the market) cannot be used for food packaging. Because these vacuum bags are often made of recycled plastic.

Food-Vacuum-Packaging-Bags(1)

Food Vacuum Packaging Bags

Food vacuum packaging bags are odorless when they leave the factory. Vacuum bags with special odors cannot be used as food vacuum bags.

Try to use food vacuum packaging bags that are not coated or plated.

In the current packaging design, in order to make the packaging bag more beautiful and corrosion-resistant, many manufacturers have used a large number of materials with coating.

This not only brings difficulties to the recovery and reuse of materials after the products are scrapped. And most of the coating material itself is toxic, if you use these food packaging bags, it will bring great harm to your health.

Sometimes, there are some products need a strict hygiene environment in the packaging process,by using a vacuum packager,you can avoid the pollution,to ensure the products are sanitary.

8.What are the categories of vacuum packagers?

In terms of the different form,there are six main types of vacuum packagers:automatic continuous vacuum packager,automatic thermoforming vacuum packager,external pumping vacuum packager,internal pumping vacuum packager,vertical vacuum packager and feed bag vacuum packager.

Automatic Continuous Vacuum Packager

Automatic continuous vacuum packager is the most common vacuum packager in the market,this is an intelligent vacuum packer which is controlled by touch screen system.It is multifunctional and can operate automatically.

The automatic continuous vacuum packager is composed of transmission system, vacuum chamber, inflatable system, electrical system, water cooling and washing device, conveyor belt and fuselage, etc.

In terms of the operation,you just need to put the product on the conveyor belt,the machine will complete a series of operations automatically.

In a brief,the automatic continuous vacuum packager has a high degree of automation and high production efficiency. It is widely used in vacuum packing of powder or liquid products.

Automatic Thermoforming Vacuum Packager

Simply speaking,automatic thermoforming vacuum packager is a type of device which makes the packaging pouch be molded automatically by heating the film.It is the most modern and automatic vacuum packager.

The working process of this type packager is:heating and stretching the below film until it’s formed,then fill the products into the formed below film,after that,heat-sealing the upper film and the below film,finally the packaging pouch is created.The assembly line production of the machine improves efficiency.

As a result,automatic thermoforming vacuum packager is widely used in all kinds of food and non-food vacuum packaging, and it is suitable for large-scale vacuum packaging needs

External Pumping Vacuum Packager

External pumping vacuum packager,as the name shows,is a device which put products on the outside of the machine during the vacuum packaging process.

On contrary to other vacuum packager,this type of machine is to put the pump into the packaging pouch,when the extraction process is finished,take out the pump and then seal the packaging pouch.

The external vacuum packing machine has high speed and is not limited by the size of the products, and it can ensure the beauty of the products to be packed

Internal Pumping Vacuum Packager

Comparatively,internal pumping vacuum packager complete the vacuum process inside the machine.The machine extracts the air of the packaging pouch in its own vacuum chamber and then completes the sealing operations immediately.

Conventionally,internal pumping vacuum packager can be divided into single chamber vacuum packager and double chamber vacuum packager.

Single Chamber Vacuum Packager

As you can see,single chamber vacuum packager is in small size,sometimes you can just put it on the tabletop.The working principle is simple,extracting the air in the packaging pouch,and then sealing automatically.

Generally,single chamber vacuum packager can be used for meat products, seasoning, soybean products, medicine, grain and other powder, solid, liquid vacuum packaging.

Double Chamber Vacuum Packager

Be similar to the single chamber vacuum packager,the double chamber vacuum packager uses its chamber to do the extraction operation,and fills inert gases into the packaging pouch,to achieve the purpose for anti-corrosion.

But the difference is that double chamber vacuum packager has two chambers,the two chambers can work alternately.

Vertical Vacuum Packager

The vertical vacuum packager is mainly provides vacuum packaging to powder and granule products.For instance,vertical vacuum packager should be applied when there are large packaging demands such as agricultural feed or chemical fertilizers.

Bag-type Vacuum Packager

As the picture shows,bag-type vacuum packager can complete the assembly line operation of packaging process automatically.Therefore,this type of vacuum packager improves the production speed and saves the cost of labor.

Generally,bag-type vacuum packager is applied in packaging casual snacks.

9.What are the application fields of vacuum packager?

After all,vacuum packager is applied in many aspects in your daily life,then this article will tell you some typical application fields of vacuum packager.

Food

To be honest,the most common application field you can see is the food packaging,vacuum packager provides vacuum packaging to food such as meat,fruit,vegetable,cookies,snacks and so on.

By using vacuum packaging,the color,taste and the mouthfeel of the products can be kept in a perfect condition,with such a advantage,vacuum packager is widely used in food packaging.

Medicine

Apart from the food industry,vacuum packager is also applied in medicine field,because of the particularity of medicine,the sanitary requirement is quite high.Vacuum packager can give a sterile package to the medicine product,then extend the storage time of the medicine and maintain the properties of drugs.

Electronic Component

Furthermore,vacuum packager can be used to package electronic components,but the material is a type of special plastic packaging pouch with shielding function,for the purpose to protect the electronic components from the damage of static electricity.

Metal

Even if metal is hard,it is easy to become oxidized,when the metal products oxidize,the appearance and the usage will both be affected.To resolve this problem,vacuum packager is also used in packaging metal.

10.What is the structure of vacuum packager?

After reading the previous text,I guess you are more interested about the vacuum packager,the next part is to tell the structure of it.In the basic case,vacuum packager consists of the following components:

Upper and lower vacuum chamber and sealing ring

Generally,vacuum packager is a cavity structure,consists of the upper and lower vacuum chamber and the sealing ring which is between the two chamber.

Hot pressing sealing device

This device is installed in the vacuum chamber,it is composed of heat seal chamber frame,reset device,hot pressing frame and hot sealing chamber.

Vacuum pump,vacuum gauge and vacuum solenoid valve

Vacuum pump is equal to the heart of the vacuum packager because it’s the extraction air device of the machine.

Vacuum gauge is to monitor the vacuum index of the packaging products.

The vacuum solenoid valve is a special valve installed on the vacuum pump,it is connected to the same power supply with the vacuum pump, and the opening and stopping of the vacuum pump directly controls the opening and closing of the solenoid valve.

Time relays, transformers and contactors

There are always two time relays,one is to control the time of vacuum,the other one is to control the time of heat-sealing.

A transformer is a static electrical device. It is according to the principle of electromagnetic induction, a certain level of AC voltage and current into the same frequency of another level of voltage and current equipment.

Contactor is actually a kind of electromagnetic switch, can automatically break the high current circuit.

11.What is the working principle of vacuum packager?

Well,after understanding the structure of vacuum packager,next part is the working principle,in other words,what’s the technology support of vacuum packager.

To explain this question,we have to talk about microorganism,which results in the spoilage of the products.As well as known,the survival of microorganism is depended on oxygen of the air.How about making it lose the oxygen?

Now you can see the working principle of the vacuum packager is so simple,just extracts the air of the packaging pouch,then the microorganism loses its main living environment,the rate of their growth and reproduction are dramatically reduced, or even suppressed .So,the purpose of using vacuum packager is achieved.

12.What is the working process of vacuum packager?

In fact,there are four parts of the whole working process of vacuum packager:vacuum,heat-seal,gas returning and circulation.

Vacuum

At the first step,the cover of the vacuum chamber is closed,and then the vacuum pump begins working,at the same time,the vacuum process is started. As this operation goes on,the vacuum index is increased,when it reaches the rated vacuum degree,the vacuum pump stop working.

Heat-seal

The second step is the heat-seal,the outer air enters the heat seal chamber through the air inlet,at that moment,the gas in the heat seal chamber is expanding because of the pressure difference between the vacuum chamber and the heat seal chamber.

As a result,the upper thermopress frame begins to move down and press the mouth of packaging pouch,meanwhile,the heat seal transformer starts working and the seal operation is finished.

Gas returning

Next,the air enters the vacuum chamber,the vacuum index return to zero,the hot press frame is reset,then the cover of vacuum chamber is opened.

Circulation

If the vacuum packager is a double chamber vacuum packager,according to the procedure steps, the vacuum chamber is moved to another vacuum chamber, and the next working cycle is starts,the left and right chambers work alternately to achieve the cycle repeats.

13.How to use a vacuum packager?

Simply speaking,the operation steps of the vacuum packager is not complex,it is easy for you to use a vacuum packager.

Firstly,you should switch the power supply,choose the correct power switch according to your demand,after that,the power indicator is on.

Secondly,put the packaging pouch in the vacuum chamber,pay attention to the mouth,it should be put on the heat sealing strip neatly.

Then,you should close the cover of vacuum chamber,and adjust the knob of vacuum operation to control the vacuum degree according to the packaging requirement.

Next,when it is at the end of the extracting air process, the inflating operation begins, and you can control the length of time by adjust the knob of inflating operation.

After the above steps,the machine enters the heat-sealing part,you should adjust the time and temperature,a vital point is that you need to adjust the knob in a small range.

Finally,when the heat-sealing operation is finished,the cover of the vacuum packager will be opened,it means that the operation process is finished,you can prepare for the next cycle.

14.What are the operation key points of vacuum packager?

Although the operation step of vacuum packager is not difficult,there are still some key point you should pay attention to when you use the vacuum packager.

The first one is that you should keep the working area clean and tidy,which can

Effectively avoid the occurrence of the safety accidents.

Besides,please don’t use the vacuum packager in moist or high temperature environments,to prevent the machine from breaking down or blowing up.And you should also keep the good lighting condition of he working area.

What’s more,the vacuum packager has its own performance range,you can’t make it work overload,too much work may cause damage to the machine itself.

And please don’t maintain the vacuum packager while it is in operation,because when it is in operation,the machine is electric,it is not suggest to maintain it in such a condition.

The last but important,when you need to replace the accessories or reinstall the machine,you should turn off the power supply before the operation.

All above is the key points of operation,during the use of vacuum packager,you should memorize these points all the time,so that you can protect your machine and extend its service life.

15.How to maintain a vacuum packager?

It is interesting that the machine is similar to human,if you don’t maintain it,it also has a temper and then breaking down.For this reason,you need to maintain the vacuum packager regularly,the maintaining methods are as follows:

The most crucial one is that the vacuum packing machine should be used in the environment where the temperature is -10℃ -50 ℃, the relative humidity is no more than 85%, and there is no corrosive gas, no dust and no explosive danger in the surrounding air.

To ensure the vacuum pump can work normally,you should check the oil of it termly,if there’s moisture in the oil or the oil turns black,you should replace with new oil.

Don’t forget,the magazine filter should be removed and washed every one to two months.

When the vacuum packager has worked for continuous three months,you should add lube to the connecting parts of the machine.

In addition,the sealing strip should be kept clean,or the quality of sealing will be greatly compromised .

In order to avoid collision,don’t place the vacuum packager obliquely in the process of transport.And when install the vacuum packager,you should guarantee the machine can be put on floor stably.

In the operation process,you should ventilate the vacuum packager before turning on the power,on the contrary,at the end of operation,you need to turn off the power firstly.

16.How to deal with the malfunctions while using vacuum packager?

Whereas,it is inevitable that the machine may be out-of-order,what can you do when it’s broken-down?Just as the follow text:

The first situation is that the vacuum degree is low,there are several possible reasons.If the oil of vacuum pump is polluted,too little or too thin,you need to wash the vacuum pump,and add new oil.If the time of extraction is too short,you need to extend it;

If the exhaust filter is blocked,you need to wash or change it;If there is air leakage,you need to turn off the power,and then check whether the solenoid valve, pipe joint, vacuum pump suction valve or the surrounding gasket of the studio have air leakage.

The second situation is that the heating part occurs malfunctions.On the one hand,it doesn’t heat,you need to check the heater strip,time relay,heating wire and other heating device to find out which part is faulted,then change it.

On the other hand,when the heating device doesn’t stop,if the time relay is out of contact, adjust or replace it. If the AC contactor doesn’t reset, repair or replace it.

The third situation is that there is aloud noise. If the vacuum pump coupling is worn or broken,you need to replace it. If the exhaust filter is blocked or installed in an incorrect position,you need to clean or replace the exhaust filter and install it correctly.If there is oil leakage,check the solenoid valve.

And there are another situation is that the oil returning valve is blocked,you need to remove and wash it.

17.How to choose a proper vacuum packager?

Actually,you already have a relatively comprehensive understanding of vacuum packing machine,now you only need to learn how to choose a vacuum packager.Well,there are many types vacuum packager on the market,to find a proper one,you need to consider the follow factors:

To the beginning,if you want to improve the production efficiency,the first factor you need to think is the packaging speed,it is suggested that you can choose a double chamber vacuum packager.

Then,if the packaging products need to be fill other gases,you need to find a vacuum packager which has the air charging system.

According to the requirement of the vacuum degree,if the packaging products need to be storage in a high degree vacuum condition,you can choose a cavity vacuum packager.

But,after all,the demand of everyone is different,the most essential principle is that you need to choose vacuum packager based on your packaging demand.
