Many people have eaten sterilized food, but they don't know what kind of equipment the sterilizer is. Sterilization pot is to use water and steam under high pressure can reach 120 ℃ or even higher temperature to eliminate all bacteria in food. Generally speaking, the sterilizer is controlled by electric semi-automatic, computer semi-automatic and computer automatic sterilizer. The semi-automatic electric appliance is much simpler than the pure manual type operated by people. It is a button type switch, which needs to be operated by the operator. Computer semi-automatic can realize curve heating, which is better for some products that need curve heating. The computer can realize PLC control, curve heating, one key start of sterilization process, no need for human operation, and also can save many medium sterilization processes, for the high amount of labor, save labor.
When using the full-automatic sterilizer, it is necessary to pay attention to its operating procedures to ensure the normal operation and service life of the equipment:
1. In order to avoid the propagation of microorganisms, the time between sealing and sterilization of the product shall not exceed the rated time.
2. Before sterilization, the operator shall check whether the initial temperature conforms to the temperature specified in the sterilization process specification. If it meets the requirements, it is normal to sterilize; otherwise, if it does not meet the requirements, it is necessary to heat the product to the specified temperature first, and then conduct sterilization after preheating for a certain time.
3. When sterilizing, it is necessary to avoid the confusion between sterilized and unsterilized products.
4. In the process of sterilization, in case of power failure, steam shutdown or other accidents, the sterilization can be suspended and handled in time. After the accident is solved, continue to sterilize or cool down to sterilize again according to the deviation correction procedure.
5. During the whole sterilization process, the sterilization operator shall operate in strict accordance with the sterilization process procedures, and carefully observe whether the temperature on the thermometer, automatic recorder and control screen is the same.
6. The sterilized can should be cooled to 30 ℃ quickly and then cooled naturally. The workshop water is ozone disinfection water without adding chlorine.
7. After sterilization, the product shall be put into the standing room after recording, and the standing time shall not be less than the rated value
The sterilizer is equipped with safety valve, pressure gauge, thermometer and other accessories to keep it safe, complete, sensitive and reliable. Maintenance and regular calibration shall be added during use. The starting pressure of the safety valve of the equipment is equal to the design pressure, which shall be sensitive and reliable, and shall be prevented from being adjusted at will. The accuracy grade of pressure gauge and thermometer is 1.5, and the difference within tolerance is normal. The pressure gauge without lead seal shall not be used, the indication of the pressure gauge fails, the scale is unclear, the dial plate is broken, the pointer does not return to zero position after pressure relief, and the lead seal is damaged, etc. shall be replaced immediately. The thermometer shall be inspected regularly. Before use, it shall be calibrated with a standard thermometer. After that, it shall be calibrated once a year. The sterilizer shall be inspected regularly. At least one external inspection shall be conducted every half a year. At least one inspection shall be conducted every year. The preparation work and inspection items before inspection shall be carried out in accordance with the "procedures" and relevant regulations. The inspection report shall be filed for record
