What is the reason for the use of Automatic sterilizer?

Automatic sterilizer is a sterilization treatment equipment that uses an electronic control system to achieve heating, heat preservation, timing and other processes. At present, edible mushroom sterilizers are widely used in agricultural cooperatives. The top of the edible fungus sterilizer is equipped with temperature gauges, pressure gauges, automatic control instruments, valves, etc., using high temperature and high pressure sterilization, which can effectively sterilize more than 99%.

How does the Automatic sterilizer work?

The Automatic sterilizer monitors the temperature change in the pot through a thermal electrode, and the temperature displayed on the display is the actual working temperature in the Automatic sterilizer. Even if the cold air is not exhausted, the temperature requirement for sterilization can be guaranteed. Since the sterilization effect of saturated steam is the best, cold air should also be discharged to improve the sterilization effect when using an automatic temperature-controlled sterilizer.

What does the Automatic sterilizer's security check do?

Automatic sterilizer

① Manually open the safety valve to see if the safety valve is normal;

②When adding water, observe whether the water level indicator light shows the water level normally;

③Under the premise of excluding cold air, observe the difference between the temperature on the display and the temperature indicated by the pressure gauge. Usually, the temperature on the pressure gauge is slightly higher than the temperature on the display. If the pressure difference does not exceed 3°C, it can be used normally.

water

The water temperature should be as low as possible. The temperature does not exceed 15 ℃. The hardness value of water is between 0.7～2.0mmoL/L.

Dryness of the steam

The sterilizer should use saturated steam with a degree of drying not less than 0.9, that is, the moisture content of the steam should not exceed 10%, and the degree of drying should not be less than 0.95 under the metal load state, so as to maintain a linear relationship between temperature and pressure.

Sterilization time

Sterilization time refers to the time required for sterilization after the sterilization chamber reaches the specified temperature during the sterilization process.

During operation, attention should be paid to observe the steam inlet speed and pressure, and generally keep the pressure and temperature rising synchronously.

What are the precautions for using Automatic sterilizer?

When the Automatic sterilizer is sterilizing liquid substances, when the sterilization is over, pay attention to the pressure relief not too fast, close the exhaust valve as much as possible, maintain the natural pressure reduction, and maintain the original balance of the system to prevent liquid reduction or splashing. Phenomenon.

Reminder: The autoclave is a high-pressure equipment, and the operator needs to be assessed and obtained by the local special equipment supervision department. The pressure valve should also be regularly sent to the professional department for inspection. On weekdays, use and maintain the equipment in accordance with the requirements of the equipment operation instructions and make a record.

WeiShu Machinery Technology (Shanghai) Co., Ltd. has been a Chinese pioneer in Automatic sterilizers for several years. You can work with customers from design to completion to ensure that all technical requirements are met.
