Operating instructions:

Generally, canned food factories use this type of horizontal sterilization pot when boiling and heating canned food under normal pressure for sterilization treatment. This equipment introduces compressed air to achieve sterilization

Now reverse pressure sterilization. If cooling needs to be carried out inside the pot, it is necessary to use a water pump to inject water into the spray pipe at the top of the pot (or use a water circulation system). During sterilization, due to heating

Raising the temperature of the can will cause the pressure inside the can to exceed the pressure outside the can (inside the pot). Therefore, in order to avoid pressurization inside the glass bottle during sterilization

Jumping lid, when the two ends of the tin can protrude, reverse pressure must be applied, that is, compressed air is passed through the pot to increase pressure and prevent the can from protruding and jumping lid

The operation situation is described as follows:

Due to the fact that compressed air is a poor thermal conductor and steam itself has a certain pressure, compressed air is not introduced during the heating process during sterilization,

Only when the sterilization temperature is reached and the pot is kept warm, compressed air is opened into the pot to increase the temperature by 0 5 ～ 0. 8 atmospheres of pressure. After being killed

After sterilization, when cooling down, stop supplying steam and inject cooling water into the spray pipe. Due to the decrease in temperature inside the pot, steaming

Steam condensation reduces the internal force of the pot

Compensate with the pressure of compressed air.

During the sterilization process, attention should be paid to the initial exhaust and subsequent release of gas to allow steam to circulate. It is also possible to release air every 15-20 minutes to promote heat exchange.

In short, the sterilization conditions must be met and carried out according to a certain procedure, including the sterilization temperature, sterilization pressure, sterilization time, and operating methods
