Product introduction of sterilizing pot and sterilizing pot

The sterilizing pot is also called the sterilizing pot. The function of the sterilizing pot is very extensive, and it is mainly used in various fields such as food and medicine.

The sterilizer is composed of a pot body, a pot cover, an opening device, a locking wedge, a safety interlock device, a track, a sterilization basket, a steam nozzle and several nozzles. The lid is sealed with an inflatable silicone rubber temperature-resistant sealing ring, which is reliable and has a long service life.

Using steam with a certain pressure as the heat source, it has the characteristics of large heating area, high thermal efficiency, uniform heating, short boiling time of liquid material, and easy control of heating temperature. The inner pot body (inner pot) of this pot is made of acid-resistant and heat-resistant austenitic stainless steel, equipped with a pressure gauge and a safety valve, which is beautiful in appearance, easy to install, easy to operate, safe and reliable.

General food factories use this type of horizontal sterilizer when they heat and sterilize packaged products in water under normal pressure. This equipment realizes back pressure sterilization by introducing compressed air. If the cooling needs to be carried out in the pot, a water pump must be pumped into the water spray pipe on the top of the pot (or use a water circulation system). During sterilization, the pressure inside the packaging bag will exceed the pressure outside the bag (in the pot) due to the temperature rise due to heating. Therefore, in order to avoid damage due to pressurization in the packaging during sterilization, it is necessary to apply counter pressure, that is, the compressed air passes through the pot to increase the pressure to prevent damage to the packaging. The operation is described as follows:

Since compressed air is a poor heat conductor, and the steam itself has a certain pressure, during the heating process of sterilization, no compressed air is put into the pot, but only when it is kept warm after meeting the sterilization temperature, the compressed air is released into the pot. Inside, increase the inside of the pot by 0.15-0.2Mpa. After sterilization, when cooling down, stop supplying air, and press the cooling water into the spray pipe. As the temperature in the pot drops and the steam condenses, the pressure of the compressed air is used to compensate for the reduction in the internal force of the pot.

During the sterilization process, attention should be paid to the initial exhaust, and then to vent, so that the steam can circulate. It can also deflate once every 10 minutes to promote heat exchange. In short, the sterilization conditions must be met and carried out according to certain procedures. The sterilization temperature, sterilization pressure, sterilization time and operation method are all specified by the sterilization process of different products.

There are many types of sterilizers, most of which are customized according to customer needs, and the scale of equipment is customized according to the output required by customers and the specific conditions of the plant. The pressure and temperature are controlled by high-precision PLC, and the pressure and temperature are too high. Early warning processing.
