The duck egg sterilizing pot is back-pressure sterilized during operation, that is, the compressed air is introduced into the pot to increase the pressure, and the soft pack is prevented from rising. The operation is described as follows: since the compressed air is a poor heat conductor, and the steam itself has a certain pressure. Therefore, during the heating process during sterilization, the compressed air is not placed, and only when the temperature is lowered after the sterilization temperature is reached, the compressed air is opened into the pot. Because after sterilization, the product temperature is at 121 ° C, then enter the cold water to cool down, the product appearance temperature is reduced, but the product center temperature is still 12 ° C, if you do not replenish the compressed air, it will rise the bag because of the internal and external pressure difference, so the reverse Pressure technology is a very important technical treatment.

Zhucheng Hengshi Machinery Duck Egg Sterilizer is equipped with automatic pressure and automatic air supply constant pressure system to ensure the quality of the product in the sterilization process. When the pressure in the sterilization pot is higher than the pressure required for sterilization, the exhaust valve will automatically open. The pressure in the pot is discharged to the pressure required for sterilization; when the pressure in the sterilization pot is under pressure, the air supply valve automatically replenishes the sterilization pot to the pressure required for sterilization.
