Characteristics of experimental special sterilizer

1. Professional experimental products: meet the needs of mass product testing and small products

2. High simulation program: identical with mass production

3. Wide application range: meet the requirements of static water spraying and rotary water spraying

4. High degree of automation: automatic recording of temperature and pressure throughout the process

5. Material: all stainless steel, meeting food hygiene requirements

Use, maintenance and repair of sterilization pot:

1. The specifications, standards and inspection basis for the design and manufacturing of this equipment: Steel Pressure Vessels (GB150-1998) and Safety Technology Supervision Regulations for Pressure Vessels (Version 99) for manufacturing, testing and acceptance; Welding shall be carried out in accordance with Welding Specification for Steel Pressure Vessels (JB/T4709-2000); Radiographic inspection shall be conducted as per Level III of (JB4730-94).

2. The user shall formulate and strictly implement the safe operation procedures of the sterilization pot according to the production process sterilization conditions of the unit and the technical performance of the sterilization pot. The safety operation procedures of sterilization pot shall at least include:

(1) The operation process index, maximum working pressure and maximum working temperature of the sterilization pot.

(2) Operation methods, procedures and precautions of sterilization pot.

(3) During production and operation, key inspection items and parts, as well as possible abnormalities and preventive measures during operation shall be focused.

(4) Maintenance method when the equipment is out of service.

3. It is strictly prohibited to operate the equipment beyond the design pressure and temperature.

4. Operators who use sterilization pots shall pass the training and examination, and strictly abide by the safety operation procedures and post responsibility system; Any abnormal phenomenon shall be handled in time.

5. The sterilizer is equipped with safety valve, pressure gauge, thermometer and other accessories, which should be safe, complete, sensitive and reliable. Maintenance and regular calibration shall be added during use. The starting pressure of the safety valve of this equipment is equal to the design pressure, which should be sensitive and reliable, and should not be adjusted randomly. The accuracy class of pressure gauge and thermometer is 1.5, and the difference within the tolerance is normal. The pressure gauge without lead seal shall not be used. The pressure gauge shall be replaced immediately in case of indication failure, unclear scale, broken dial, pointer not returning to zero after pressure relief, and lead seal damage. The thermometer shall be regularly inspected. Before use, it shall be calibrated with a standard thermometer. After that, it shall be verified once a year. If the mercury column breaks and the difference between the mercury column and the standard temperature exceeds 0.5 ℃, it shall be sent for repair or replacement.

6. Sterilizing pans shall be inspected regularly, external inspection shall be carried out at least once every six months, and comprehensive inspection shall be carried out at least once every year. Preparations and inspection items before inspection shall be carried out in accordance with "Procedures" and relevant regulations, and inspection reports shall be filed.

7. The sliding and rolling contact parts such as bevel self-locking wedges, rollers, pan ears, rotating ring flanges, etc. shall be often coated with grease and oil during use to ensure that the friction surface is lubricated.

8. If the sealing ring on the flange surface of the boiler body is aged, damaged or excessively worn, it should be replaced in time to ensure sealing and prevent leakage.

9. When the equipment is out of service, the internal and external surfaces of the sterilization pot and pot cover shall be cleaned. The exposed processing surface is brushed with antirust paint, and the safety detection control instrument is covered and protected.
