With the development of modern packaging technology, more and more products begin to use vacuum packaging for preservation and preservation, and the application of vacuum packaging machines has become more and more extensive. So, what is the working principle of the vacuum packaging machine?

define the

we need to clarify the concept of vacuum packaging. Vacuum packaging refers to the extraction of the internal air of the packaged material in a sealed environment, so that it is packaged in a vacuum state, so as to achieve the effect of preservation and corrosion. The vacuum packaging machine is the machine equipment that completes this process.

types

There are two types of common vacuum packaging machines: sealed and side suction. Sealed vacuum packaging machine can be divided into manual, semi-automatic and fully automatic three; side suction vacuum packaging machine is usually used for mass packaging production.

working steps The working steps of

vacuum packaging machine usually include the following stages:

1. Place the packaged object. Place the items to be packaged in a vacuum packaging bag and ensure that the mouth of the bag is not squeezed, deformed or damaged.

2. Sealing. The bag mouth is processed by a sealing machine, leaving a certain width of the opening at the bag mouth.

3. Pumping. Put the bag in the vacuum packaging machine, start the machine, and remove the gas from the bag. At this time, negative pressure will be generated in the bag.

4. Sealing. After the end of the pumping process, start the sealing function of the vacuum packaging machine to seal the mouth of the bag again to prevent the oxygen inside from entering again.

advantages

vacuum packaging machine has the following advantages:

1. Extend the shelf life of food. Vacuum packaging can extract oxygen from the bag, thereby inhibiting the growth of bacteria and extending the shelf life of food.

2. Protect product quality. Vacuum packaging can reduce the oxidation, deterioration and discoloration of the product, and maintain the original freshness and taste of the product.

3. Save packaging materials. Vacuum packaging can reduce the volatile substances converted by oxygen, thereby reducing the use of packaging materials and saving costs.

summary

Through the introduction of this article, I believe readers have a deeper understanding of the working principle of vacuum packaging machines. With the increasing demand for the quality of food and other perishable items, the future application prospect of vacuum packaging technology is unlimited.
