Some students asked, is the vacuum packing machine necessary for the product using the autoclave? First answer the question Yes, vacuum packaging is required first. The sterilization principle of high temperature and high pressure sterilization pot is to kill microbes and bacteria in the product under high temperature environment, so as to inhibit the propagation of bacteria and achieve the purpose of corrosion prevention.

Vacuum packaging is the prerequisite. If the product is not packaged in vacuum, it will come into contact with the air after coming out of the sterilization pot. The air contains a lot of microbes, which pollutes the product again. Sterilization is also a waste of work. You can see from the supermarket, basically the food is vacuum packaging, vacuum packaging is isolated from external pollution, the interior is also subjected to high temperature sterilization, without bacteria, microbial products will not deteriorate, so can be stored for a long time.
