Background technique

The production and processing of meat products are easily contaminated by microorganisms. The growth and reproduction of microorganisms can lead to spoilage of meat products, shorten the shelf life of products, and even lead to the occurrence of poisoning events. Therefore, sterilization treatment is essential for meat products. Food sterilization is an indispensable link in the processing of meat products, and it is necessary to select efficient sterilization treatment methods. The traditional methods mainly include heat treatment and chemical treatment. These methods are not suitable for sterilization of meat food, and will produce harmful residues. The safety of the product is affected. Because of the high thermal sensitivity of meat food, thermal sterilization technology is greatly limited in this field. Various active groups and particles generated by plasma can react with various components in the microorganism. , thus hindering the normal growth of microorganisms and eventually leading to death, the temperature has no obvious change during the reaction process, and there is no direct contact with meat food, which is gradually receiving more and more attention.

The traditional plasma sterilization device only passes the meat food through the gap area between the two polar plates, so that the plasma generated by the two polar plates can be sterilized without forming a plasma chamber. Some sterilization devices with a plasma chamber can only sterilize one piece at a time. The meat food is sterilized, no protrusions are provided, and the protrusion and the meat food will not be relatively static during the movement process, and a mobile plasma chamber cannot be formed between the protrusion and the plate, and the sterilization time and sterilization effect are poor. , There is no fan in the plasma chamber, which will not make a circulating wind in the plasma chamber, resulting in uneven distribution of plasma in the plasma chamber, resulting in different sterilization effects at different positions of the meat food, reducing the sterilization effect of the meat food.
