What products are applicable to a bactericidal cooker?

Can be divided according to different forms of packaging:

Different packaging materials determine the specific structure of the sterilization kettle. Let’s discuss the different sterilization kettle structures corresponding to various packaging materials.

Soft packaging products: Soft packaging products can be changed with the shape of the product. If the soft packaging is vacuum, the shape of the packaging material will be closely attached to the outer surface of the product and shows the appearance of the material. Because it is a vacuum -packaged product, the pressure in the sterilization kettle during the sterilization process can be at a certain value at a certain value of vaporization pressure when the circulating water sterilization temperature. Under such a prerequisite, using a fixed -voltage sterilization mode is the best choice. For the heat transfer effect, the state of all products in the water is the fastest and sufficient. That is, the best sterilization model is a water bath -type sterilization kettle

Glass bottle packaging products Glass bottle should pay attention to the environmental temperature cannot change suddenly during the sterilization process. The glass bottle is a rigid material. It usually uses high -temperature filling to make the pressure in the packaging material in the room at room temperature lower than the atmospheric pressure. That is, a negative pressure state (one of the purpose of the negative pressure status is to cause some gases in the storage and transportation process before consumption. The bottle cap is raised, reminding consumers that the materials inside the bottle cannot be eaten again). However, in the process of high temperature sterilization, the pressure in the glass bottle will increase. To prevent circulating water outside the bottle, the pressure outside the bottle should not be sealed in the bottle. The pressure outside the bottle should not be higher than the pressure in the bottle. According to these features, it is more appropriate to choose a water -water sterilization mode for glass bottles packaging products.

The packaging materials such as iron can packaging materials look like iron cans, but because of its large specifications, its pressure difference is weak. Adjust the temperature changes so that the pressure difference between the iron can be controlled within a tolerable range. It should be noted that the corresponding pressure should be different from the same temperature during the heating stage and the cooling stage. Because the heating stage is to pass the heat to the product, the temperature in the tank is lower than the temperature in the sterilization kettle, the pressure required in the sterilization kettle will be lower; and during the cooling stage, the heat inside the product is emitted outward, and the can of the tank, the can of the can, and the tank. The temperature in the body is higher than the temperature in the sterilization kettle, and the pressure required in the sterilization kettle will be higher, which needs to be paid attention to. For different product specifications and different contents, the pressure controlled is also different, and it needs to be set one by one.

The sterilization of plastic packaging stretching membrane packaging still requires strictly controlling the value of the pressure during the temperature transformation process. Because there is a certain air in the box, the heat transfer is relatively slow, so during the process of heating and cooling, the temperature changes cannot be too fast, and all the products placed in the sterilization kettle must be synchronized in a smaller temperature range as possible. Rising temperature and cooling. The purpose of this is to make the packaging material basically do not withstand the pressure difference, so that the packaging materials can not be deformed due to the effect of pressure during the entire sterilization process. As mentioned earlier, to make all products in the sterilization kettle simultaneously heating and cooling in a smaller temperature range, which has higher requirements for the thermal distribution performance of the bactericidal kettle.

The sterilization of products such as box -shaped packaging still requires strictly controlling the value of the pressure during the temperature transformation process. Because there is a certain air in the box, the heat transfer is relatively slow, so during the process of heating and cooling, the temperature changes cannot be too fast, and all the products placed in the sterilization kettle must be synchronized in a smaller temperature range as possible. Rising temperature and cooling. The purpose of this is to make the packaging material basically do not withstand the pressure difference, so that the packaging materials can not be deformed due to the effect of pressure during the entire sterilization process. As mentioned earlier, to make all products in the sterilization kettle simultaneously heating and cooling in a smaller temperature range, which has higher requirements for the thermal distribution performance of the bactericidal kettle.

The sterilization of cup -shaped packaging bowl -shaped packaging still requires strict control of the value of the pressure during the temperature transformation process. Because there is a certain air in the box, the heat transfer is relatively slow, so during the process of heating and cooling, the temperature changes cannot be too fast, and all the products placed in the sterilization kettle must be synchronized in a smaller temperature range as possible. Rising temperature and cooling. It is worth noting that if the air content in the packaging material is small, you can consider the problem of compression of the product, that is, you can increase the anti -pressure in the sterilization kettle, so as to make the sterilization process always be in one sterilization kettle in a one pressure. Because the materials in the packaging material are not compressed and the air content is small, even if the external pressure is large, it will not have the effect of deformation on the packaging material itself.
