There are a lot of food in our daily life, can be used to sterilization sterilization pot, the production of canned production are sterilization pot for sterilization, food processing plants now for canned atmospheric water heating sterilization when using this form of horizontal sterilization pot, horizontal sterilization pot by introducing compressed air back pressure sterilization can be realized. Such as cooling should be carried out in the pot, must use water pump into the pot on top of the spray pipe (or use the water cycle system).
When sterilization, canned due to heating temperature, the pressure in the canned more than outside the tank pressure (in pot). Therefore, in order to avoid bactericidal glass tank pressurization and jump cover, two end face bulging of tinplate cans, must exert pressure, especially for high temperature sterilization of canned meat more so.

Using negative pressure sterilization, namely is to use compressed air into the pot to increase pressure, prevent the canned jump convex tank and cover, its operation points above are as follows: due to the compressed air is bad conductors, besides, steam is itself has a certain pressure. Therefore, in the process of sterilization temperature when, not in the compressed air, but only after the sterilization temperature reached in the heat preservation, to open the compressed air into the pot, add 0.5 ~ 0.8 a tm to the pot. After sterilization, cooling, cooling, stop supply steam, cooling water into the water spray. Due to the temperature drop in pot, steam condensation, and make the pan internal force to reduce the pressure of compressed air is used to compensate.

Should be paid attention to in the process of sterilization, vent, and then discharge of steam, the steam flow. Can be deflated once every 15-20 minutes, promote heat exchange. Anyhow must meet the provisions of the sterilization conditions, according to certain procedures, the sterilization temperature, the size of the pressure sterilization, sterilization time length and all the canned products such as sterilization operation method to make specific provisions.

Life still has a lot of food can sterilization pot equipment, such as sausage, rice pudding, and milk drinks, aquatic products, agricultural products, etc., sterilization pot can be used to operate.
