Regarding the operation of the sterilization pot, what must not be less?

Before operating the equipment, we should first understand the composition and characteristics of the sterilizer:

The sterilization pot includes the body, the lid, the bending arm device, the safety interlocking device, the rail, the sealing ring, the steam, the nozzle, the cooling water pipe, the pipeline, the pressure maintaining device and the gate valve. The sealing device of the air-cushion sealed sterilizer adopts domestic advanced technology configuration, the whole machine has reasonable design, safe and reliable operation, compact structure, easy operation, convenient maintenance and simple installation. The pressure control adopts an automatic control device, which can be automatically adjusted when the pressure exceeds the limit to ensure that the container works normally within the allowable range.

So, what are the procedures and precautions for the operation of the sterilization pot equipment? The following is a detailed explanation:

Check

(1) The user shall implement the provisions of Chapter 5 of the “Pressure Vessel Safety Supervision Regulations” issued by the State General Administration of Labor in May 1981, and the relevant container safety technical regulations.

(2) The user should formulate the safe operation rules of the sterilization pot according to the sterilization conditions of the production process of the unit and the technical performance of the sterilization pot, and strictly enforce it.

2. This equipment is strictly prohibited to exceed the design pressure and exceed the design temperature.

3. The operator who uses the sterilization pot should pass the training and test, and should strictly abide by the safety operation rules and the post responsibility system. And always maintain safety accessories, complete, sensitive, reliable, and found that abnormal phenomena should be handled in a timely manner.

4. The sterilization pot is equipped with safety accessories such as safety valve, pressure gauge and thermometer. The temperature adjustment device is added to the equipment, and maintenance and periodic verification should be added during the use. The safety valve opening pressure of this equipment is equal to the design pressure, and should be kept sensitive and reliable at all times, and should be prevented from being adjusted at will. The accuracy of the pressure gauge is not less than 2.5, and the lead-free pressure gauge must not be used. The accuracy should be at least once every inspection, the pressure gauge indicates failure, the scale is unclear, the dial is broken, the pointer does not return to zero after the pressure is released, and the seal is damaged, etc., should be replaced immediately. The thermometer should be inspected regularly. It should be calibrated with a standard thermometer before use. It should be verified once a year. If the mercury column breaks and the difference from the standard temperature exceeds 0.5 °C, it should be repaired or replaced.

5. The sterilizing pot should be inspected regularly, at least once every six months, and at least once every year. The preparations and inspection items before the inspection are carried out in accordance with the “Procedures” and relevant regulations, and the inspection reports are filed and filed.

The safe operation procedures of the sterilization pot should at least include:

1, the operating parameters of the sterilization pot and zui high working pressure, zui high working temperature.

2, the operation method and procedures of the sterilization pot and precautions.

3. During the production operation, it is important to check the project and location, as well as the abnormal phenomena and preventive measures that may occur during operation.

4. Sealing and maintenance methods when the equipment is deactivated.

After checking the above items, the equipment can be operated. The whole process of the sterilization pot is as follows:

1 The packed product basket is sent to the sterilizer and the kettle door is closed. Then the door is secured by a triple safety interlock. In the whole sterilization process, the mechanical and electrical methods are interlocked to ensure the safe operation of the sterilization pot.

2 into the softened water: the sterilizing water is injected into the sterilizing pot to the appropriate water level.

3 Temperature rise: The sterilizing water in the pot is continuously circulated by the water, and the steam is introduced into the heat exchanger and the sterilizing water is exchanged for heat, and the temperature of the product is continuously increased.

4 Sterilization: The circulation pump continuously circulates the sterilizing water in the closed circuit system, and the water forms a mist sprayed onto the surface of the food. The pressure inside the tank is adjusted to a desired range by a pressurizing valve and a pressure relief valve.

5 Cooling: Stop the steam and start to pass cold water into the heat exchanger. The sterilizing water in the pot is continuously circulated, and the temperature of the sterilizing material is continuously reduced, and it is lowered to the set temperature.

6Recycling: The circulating pump draws the sterilizing water back to the hot water tank for the sterilization of the next batch of food.

7 After the recovery is completed, the pressure in the pot is vented through the exhaust valve, the air introduction valve is opened, the pressure in the pot is zero, and the product is discharged.

In summary, each point is a matter to be paid attention to when operating the sterilization pot, and it is not necessary to reduce the use of the sterilization pot to achieve the desired effect.
