Vacuum Pump for Vacuum Packaging Machine

Vacuum packaging machines usually need vacuum pumping to achieve a certain degree of vacuum packaging process. The main function of vacuum packaging is deoxidization, which is beneficial to prevent food deterioration. The principle is relatively simple. Because food mildew deterioration is mainly caused by the activities of microorganisms, and the survival of most microorganisms (such as fungi and yeasts) needs oxygen, while vacuum packaging can prevent food deterioration. It is based on this principle that oxygen is removed from the packaging bags and food cells, so that microorganisms lose their living environment.rotary-vane-vacuum-pump-distributor


Experiments show that when the oxygen concentration in the packaging bag is less than 1%, the growth and reproduction speed of microorganisms will decrease sharply. When the oxygen concentration is less than 0.5%, most microorganisms will be inhibited and stop breeding. (Note: Vacuum packaging can not inhibit the food deterioration and color caused by anaerobic bacteria reproduction and enzymatic reaction, so it needs to be combined with other auxiliary methods, such as refrigeration, quick freezing, dehydration, high temperature sterilization, irradiation sterilization, microwave sterilization, salt pickling, etc.).vacuum-pumps-price
