The main function of the vacuum packaging machine is to remove oxygen to prevent food from spoiling. The deterioration of food mold is mainly caused by the activity of microorganisms, and the survival of most microorganisms (such as mold and yeast) requires oxygen, and vacuum packaging is used. This principle removes oxygen from the inside of the package and the food cells, causing the microorganisms to lose their living environment.
There are many types of vacuum packaging machines. Below, let's take a look at the types and applications of vacuum packaging machines.
When purchasing, the packaging of solid and granules is relatively dry and non-corrosive. It can be made of aluminum alloy, and the package is filled with soup. The material with high salt and acid content can be made of stainless steel or aluminum-magnesium alloy. . The sealing ring is generally made of silicone rubber and black rubber. A few low-grade products use foamed rubber. The silicone rubber has high temperature resistance, corrosion resistance, good sealing performance and long service life. The foamed rubber has poor sealing performance, easy to fall off and short service life.
So how do you choose a vacuum packaging machine?
First of all, making food healthy is the key to maintaining the health of materials that are prone to deterioration, such as food, and understanding the vacuum packaging skills. Vacuum packaging depends on the tightness of the overall packaging. If the packaging is not good, there will be a big omission in the use. Selecting the vacuum packaging machine will also cause more problems.
Secondly, the vacuum packaging machine meets the needs of consumers: the choice of vacuum packaging machine must avoid the extension of the system based on the vacuum packaging gap, and maintain the consumption choice of vacuum packaging. In the qualitative analysis process, only the vacuum packaging machine is The use also takes the advantage of choosing the packaging machine as one.
