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:
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.
It is the collection tank of machine with lower free flow valve for releasing load. All the material is gathered in its pure form in hopper. After completing each cycle of vacuum feeding the hose of hopper is opened to deliver bulk.
Filters are located inside the vacuum feeding machine and are used for the processing of loaded particles. They separate material from air and removes dust and waste from them.
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.
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.
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.
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.
It is located inside the suction tube which helps to adjust the amount of air by increasing or decreasing its level.
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 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.
An essential part which every machine requires for easy mobility is exactly the movable wheels. They are located under the machine with 360° degree movement strength.

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