Introduction of steam sterilizer

Steam sterilizer is a kind of sterilization boiler, with shutter type pressure vessel safety interlock device, independent electrical instrument control system, automatic constant temperature, heat preservation and timing. It is made of stainless steel material. It is beautiful, hygienic, safe and durable.
Advantages of steam sterilizer
1. This equipment has the characteristics of a double-layer water bath sterilizer. The output is doubled compared to the double-layer sterilizer. Save energy and time. Save equipment investment. Reduce user production costs.
2. Automatically switch the direction of water flow in the pot. The temperature is uniform and no dead ends.
3. High-temperature and short-time double-pot cross-sterilization saves time and effort.
4. The whole process is automatically controlled by the computer. No manual operation is required.
5. The temperature in the pot is automatically adjusted by the temperature film regulating valve. High sterilization accuracy.
6. The function of measuring f value.
7. Set up a variety of full-time sterilization formulas according to different products.
Steam sterilizer operating instructions
When a general food factory cooks and heats the packaged product under normal pressure. Will use this horizontal sterilizer. This equipment realizes back pressure sterilization by introducing compressed air. If you need to cool in the pot, pump it into the spray pipe at the top of the pot (or use a water circulation system). During the sterilization process. The temperature rises due to heating. The pressure inside the packaging bag will exceed the pressure outside the bag (in the pot). therefore. In order to avoid damage caused by pressurization in the packaging during the sterilization process. Need to apply back pressure. That is, compressed air passes through the pot to increase the pressure. Prevent damage to the packaging. The operating conditions are as follows:
Because compressed air is a poor heat conductor. The steam itself has a certain pressure. Therefore, compressed air is not released during the heating process during sterilization. After reaching the sterilization temperature, it is put into the pot when it is kept warm. Increase the pressure in the pot by 0.15 ~ 0.2 MPa. After sterilization and cooling. Stop the gas supply. Press the cooling water into the nozzle. Because the temperature in the pot has dropped. The steam condenses. The internal force of the pot is reduced by the pressure of the compressed air. .
