Working principle and operation precautions of high temperature sterilization pot

The high temperature sterilization pot uses high temperature saturated steam to sterilize the product. Suitable for canned meat products, canned drinks, canned fruits and vegetables, glass bottled fruits and vegetables, etc.

The working principle of high temperature sterilization pot:

1. The bottom of the high-temperature sterilization pot is a storage tank. When the material is loaded into the sterilization basket and the pot door is closed. The circulating pump pumps the sterilizing water in the water tank through the filter, and sends it to the heat exchanger for heating with steam. Spray the spray pipe from the top of the sterilization basket evenly over the desired sterilized material. Due to the large amount of circulation, the temperature in the high temperature sterilization pot is very uniform. The PLC automatically opens or closes the steam valve based on the measured temperature of the sterilizing water.

2. By calculating the pressure required in the pot at this temperature, the switch of the inlet and outlet valves is automatically controlled, so that the pressure in the pot and the temperature in the sterilization process of the whole high-temperature sterilization pot have a certain relationship. When the high temperature sterilization pot is in the heating and holding state, the steam valve and the steam trap are automatically opened, and the cooling water valve is automatically closed; when the high temperature sterilization pot is in the cooling state, the steam valve and the steam trap are automatically closed, and the cooling water inlet and outlet valves are automatically opened. .

3. After the sterilization is finished, the high temperature sterilization pot circulation pump stops, and the circulating water returns to the bottom water storage tank for the next cycle.

High-temperature sterilization pot is mainly used in various fields such as food industry, medicine, etc. It has the characteristics of large heating area, high thermal efficiency, uniform heating, short boiling time of liquid material, easy control of heating temperature, etc., so it is widely used. In the same operation, you need to pay attention to many aspects of the problem. Here are a few simple things:

1. The sterilizer must be equipped with a mercury thermometer and pay attention to the range, scale and installation position of the thermometer.

2. It is necessary to equip the automatic temperature recorder, because there are many times when manufacturers save costs, they will be omitted. So be equipped when using.

3. If it is water, be sure to install a water circulation system and install a flow meter on the circulation line to indicate a steady flow.

4. There are requirements for the size of the sterilizer pot, the layout of the pipeline, and so on.

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.
