The main mechanism of action of
fully automatic (inflatable) vacuum packaging machine The fully automatic (inflatable) vacuum packaging machine adopts a microcomputer program control system and a liquid crystal display. The working program control is precise and stable, and the parameters are set intuitively. Users can preset the working mode according to their needs: vacuuming, gas filling, sealing and other procedures. When using, it is necessary to call up the preset one, and the operation is simpler, more convenient, and stable in performance.
The machine is leading the way, and the nozzle can be adjusted freely. In addition to the automatic lifting drive design, it is only necessary to automatically raise or lower to a suitable vacuum position, so that the pumping and charging speed is faster, the work efficiency is higher, and the operation is extremely simple and convenient. At the same time, it has the functions of vacuuming and aeration, or filling and filling gas, and it is more convenient to use the packaging to keep fresh, color and quality.
Fully automatic (inflatable) vacuum packaging machine manufacturers analyze its working principle:
The main function of vacuum packaging is to remove oxygen, which is beneficial to prevent food spoilage. The principle is also relatively simple, because 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. Vacuum packaging is the use of this principle to remove oxygen from the inside of the bag and the food cells, so that the microorganisms lose the "environment of survival." Experiments have shown that when the oxygen concentration in the package is less than 1%, the growth and reproduction rate of microorganisms drops sharply. When the oxygen concentration is ≤ 5%, most microorganisms will be inhibited and stop breeding.
Note: Vacuum packaging can not inhibit the deterioration and discoloration of food caused by anaerobic bacteria reproduction and enzyme reaction, so it must be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt cells. System.
In addition to inhibiting the growth and reproduction of microorganisms, vacuum deoxidation is another important function to prevent oxidation of foods. Oils and fats contain a large amount of unsaturated fatty acids, which are oxidized by the action of oxygen to deteriorate the taste of foods. In addition, oxidation also causes loss of vitamins A and C, and unstable substances in the food coloring matter are subjected to oxygen to darken the color. Therefore, oxygen scavenging can effectively prevent food from spoiling and maintain its color, aroma, taste and nutritional value.
