Operating instructions of sterilization pot:

General canned food factories use this type of horizontal sterilization pot when boiling and heating cans under normal pressure. This equipment can realize back pressure sterilization by introducing compressed air. If cooling needs to be carried out in the boiler, water pump must be used to pump water into the spray pipe at the top of the boiler (or water circulation system shall be used).

During sterilization, the pressure inside the can will exceed the pressure outside the can (in the pot) because the temperature of the can will rise due to heating. Therefore, in order to avoid cap jumping due to pressurization in glass bottles during sterilization, counter pressure must be applied to the protruding ends of tinplate cans, especially for meat cans requiring higher sterilization temperature.

The use of counter pressure sterilization means that compressed air is introduced into the pot to increase the pressure, so as to prevent the can from protruding and jumping. The operation is described as follows: since compressed air is a poor heat conductor, the steam itself has a certain pressure. Therefore, during the temperature rise process during sterilization, compressed air is not put into the boiler, but only when the sterilization temperature is reached and the temperature is maintained, compressed air is opened into the boiler to increase the pressure in the boiler by 0.5~0.8 atmospheres. After sterilization, when cooling, stop supplying steam and put cooling water into the spray pipe. The pressure of compressed air is used to compensate for the reduction of the internal force of the boiler due to the temperature drop in the boiler and the condensation of steam.

In the process of sterilization, attention should be paid to the initial exhaust, and then the steam should be released to make the steam circulate. It can also deflate every 15-20 minutes to promote heat exchange. In a word, it must meet the requirements of sterilization conditions and be carried out according to certain procedures. The sterilization temperature, sterilization pressure, sterilization time and operation method are all specified by the sterilization process of canned products.
