5.Describe The Major Parts Of A Gas Flushing Machine?

Major-Parts-Of-A-Gas-Flushing-Machine

A gas flushing machine is the compound of various parts which consist of:

Control Panel

This part of machine is actually touch screen display through which configurations and dimensions of a gas flusher are fixed. It is usually located on the top front of machine.

Emergency Button

Emergency button keeps the processing safe and allow quick break of whole mechanism if any sort of sudden emergency or mishap occurs.

Table

Almost every gas flushing machine has straight, flat table on which the task of packaging is accomplished. One by one bags are kept on it, gas flushed and sealed sequentially.

Film Roller

Another component of a gas flushing machine is the film roller, fixed in specific direction to the goods so the film can be applied in perfect way without leaving any food uncovered.

Sealer

Sealer is located on the upper front of machine. It consists of sealing frame and is required to seal the loaded bags with thick layer.

Gas Pump

The most significant part of a gas flusher is obviously a gas pump comprised of inert gases. It supplies the machine with sufficient amount of gas to complete its modified air packaging. It constantly fills the pouches with gas and extract accordingly.

6.How Does A Gas Flushing Machine Can Be Operated?

Gas Flushing Machine Can Be Operated

The operating procedure of a gas flushing machine is quite easy. The only thing you need to understand is to maintain the level of gases and make sure that sealing is firm. Further process can be analysed by following steps:

Barrier bag is essential for protecting food and especially when using a gas flushing machine. In this way, a loaded vacuum container is placed in a gas flushing machine, where it injects gas into bag and displaces the oxygen inside it.

The infused gas act as a buffer against bacteria and the repeated flushing of gas completely remove oxygen from package. Consequently, a tight thick layer of sealing is applied.

For fragile products which are likely to crush and damage, some amount of gas is leaved in bag. Once the sealing is completed, package is fully enclosed and ready for shipping to stores.

7.What Are The Types Of A Gas Flushing Machine?

There are six types of a gas flushing machine available in market which is described below:

Vertical Flow-Pack

Vertical-Flow-Pack

In vertical flow pack machine film is drawn down and single layer of film is applied over the product. After the continuous gas flushing the film is sealed under the center of package. This machine is mostly used for bulk products and diced-food stuff.

Working Principles

In vertical flow pack machine film accurately weighed and drawn down from film roller. A vertical pouch is then formed after single layer of film is dispensed. At this stage products are released from hopper and the continuous gas flushing is going on after which sealing is achieved under the center of package.

8.Explain The Common Gases Used By A Gas Flushing Machine?

Common-Gases-Used-By-A-Gas-Flushing-Machine

A gas flushing machine commonly uses nitrogen and other exotic gases for flushing vacuum containers. These gases varies in their nature and functions such as:

Nitrogen

Nitrogen is an inert non reactive gas which is mostly used by a gas flushing machine particularly for eliminating oxygen present inside the vacuum containers. It is best for snack foods and fat containing food as it prevent them from oxidative deterioration.

Carbon Dioxide

Carbon dioxide is an anti microbial agent which restrains aerobic bacteria and molds from growing. The higher level of carbon dioxide can further extend the shelf life of products. Meanwhile, balance should be kept for level of carbon dioxide because its extreme degree can lead to the flavor tainting and drip loss.

Argon

Similar to Nitrogen, argon is also an inert gas. Having been a tasteless and odorless gas, argon is heavier than nitrogen and inhibits the microbial buildup, degrative chemical reactions and enzymic activities.

Carbon Monoxide

Carbon monoxide is a toxic gas which is formed by the incomplete combustion of feul. It is best for maintaining the bloom red color of meat along with retaining its actual tenderness and juiciness. It may be hazardous for inhaling but is safe for packaging purpose thus it keeps the pathogenic bacteria far away from meat and allow it to stay longer.

9.What Factors Are Necessary To Determine The Required Gas Flushing For Foodstuff?

The amount of gases necessary for storing your food is not always be the same. You have to consider some factors for knowing the required amount. For this we have pinned three most important points:

Type of Food

Type of Food

Food which gets spoil quickly will definitely require more time and amount of gas flushing than that of food with stable shelf life. For instance, vegetables are more likely to influence by the surrounding atmosphere compare to dry cereals.

Type of Packaging

Type-of-Packaging

Check whether your packaging containers are sturdy or porous. If they are solid and dense few blows of gas flushing are good. While as, weak containers have tendency of gas escaping.

Type of Storage

Type of Storage

We are familiar with the fact that packed food can be stored either in refrigerator, freezer or in open shelves. Here it is important to note that a product which is supposed to be stored in room temperature would need more amount of gas for its preservation.

10.Which Is More Suitable Between Gas Flushing And Vacuum Extraction?
NoFactorsVacuum ExtractionGas Flushing
1DefinitionVacuum extraction only relies on air removal and suck out the air from container but a small amount of oxygen is still present inside which can grow microbe.Gas flushing not only excludes the air out but also infiltrates the gases continuously to ensure zero percent of oxygen presence.
2SizeVacuum packaging machine is based on “one size fits all” method.Gas flushing machine is not confined to any particular size rather it is more versatile
3MaterialVacuum packaging is suitable for meat, hard cheese, dry food etc.Gas flushing is best for processing sensitive to sturdy products like soft cheese, bakery products etc.
4ApplicationVacuum packaging is better for small scale industries and is inexpensive.Gas flushing machine is bulky with expensive price although it is best for large scale industries.
5Presence of gasAs it extracts the air out from bag, material may collapse or released from bag due to spoilage.Since, it replaces oxygen with other gases so the beautiful shape of products can be maintained which also prevent food damage.
