High temperature and high pressure sterilization pot operation steps

1, obey the sterilization process operating specifications, zui high working pressure 0.25Mpa, zui high working temperature 123 ° C

2. Sterilization pot operation method;

a. Push the sterilization frame of the loaded goods into the tank and close the tank door;

b. Start the quick-opening safety interlocking device. When the “door closed in position” and “safety pin in place” warning lights do not flash, it indicates that the quick opening door has reached the predetermined closing position, close the lower end of the tank exhaust valve, open the steam valve, when the tank When the cold air in the body is exhausted, close the upper exhaust valve to gradually increase the temperature inside the tank;

c. When the tank is raised to the specified temperature, close the steam inlet steam valve to make the temperature constant. At a constant temperature, maintained for the required time (different product insulation time is different), meat products are generally at 121 ° C,

d. During the heat preservation process, the lower exhaust valve of the tank is opened from time to time, so that the condensed water in the tank is immediately discharged. If the temperature of the tank is lowered, the inlet valve needs to be opened again to make the temperature of the tank reach the specified temperature (heating time) That is the sterilization time);

e. After reaching the holding time, open the lower exhaust valve to discharge the steam in the tank. After the Zui, open the upper exhaust valve to exhaust the steam in the tank. When the pressure difference in the tank is zero, the door switch can be opened and the contents of the tank can be taken out.

3. This equipment is strictly prohibited to exceed the design pressure (0.3Mpa) and exceed the design temperature (143°C).

4. Operators should strictly abide by the safety operation rules and post responsibility system, and always keep the safety accessories complete, sensitive and reliable, and detect abnormalities in a timely manner.

5. The sterilization pot is equipped with safety valve, pressure gauge and thermometer safety accessory. During the use process, maintenance and regular calibration should be strengthened. The safety valve opening pressure of this equipment is equal to the design pressure. It should be kept sensitive, reliable and prevent random adjustment. The accuracy of the pressure gauge is not less than 2.5. The lead-free pressure gauge must not be used. The accuracy should be checked at least once a year. The pressure gauge indicates failure, the scale is unclear, the dial is broken, the pointer does not return to the original position after the pressure is released, and the seal is sealed. Damages, etc. should be replaced immediately. The thermometer should be periodically calibrated. It should be calibrated with a standard thermometer before use. It should be calibrated once a year. If the mercury column breaks and the temperature difference is more than 0.5 °C, it will be repaired or replaced.

6. The sterilizing pot should be inspected regularly, and at least one external inspection should be conducted every year, and at least once every three years.

7. During the use process, the resident mechanism should apply grease and oil to the sliding and rolling contact parts of the lock block and the active ring blue to ensure that the friction surface is in a lubrication state.

8. When the sealing ring on the flange surface of the pot body is aging, if the defect and friction are too large, it should be replaced in time to ensure the seal and prevent leakage.
