[0002] Bacteria refer to one of the main groups of organisms, and they also have a great impact on human activities. On the one hand, bacteria are the pathogens of many diseases, are highly contagious, and are extremely harmful to society. On the other hand, humans often use bacteria for production or processing; and in the process of food processing, food will come into contact with various bacteria. In order to increase the cleanliness and quality of food, today's production companies often use sterilization equipment to sterilize and disinfect the surface of food to improve the quality of food production.

[0003] Prior art includes a utility model with publication number CN219613005U, which discloses a food surface sterilization device, which adopts a frame, a processing box installed on the frame, and a conveying component for conveying food in and out of the processing box; the conveying component includes a rotating shaft installed on the four corners of the frame and a conveyor belt sequentially attached to the outside of the four rotating shafts; a partition is fixedly arranged in the processing box, and the interior of the processing box is divided into a spray chamber and a sterilization chamber by the partition, and a spray component and a heating component are arranged in the spray chamber along the conveying direction of the conveyor belt, and a feeding component and a sterilization component are arranged in the sterilization box along the conveying direction of the conveyor belt; the shortcomings of the prior art are overcome, food is conveyed by a conveyor belt, and the surface of the food is disinfected and sterilized by two groups of ultraviolet lamps at the same time, the degree of automation is high, the operation is simple and convenient, and the problem that most existing food sterilization equipment adopts immersion or spraying for disinfection and sterilization, but there are many foods that cannot be immersed and sprayed, and there is a lack of disinfection and sterilization equipment is solved.

[0004] The inventors have discovered in their daily work that in the process of sterilizing and disinfecting food with the help of sterilization equipment, there are existing sterilization equipment such as the above-mentioned ones. When in use, the conveyor belt that conveys food will be dried with the help of a heating mechanism to assist the spray mechanism in disinfecting and sterilizing the conveyor belt. Since the distance between the hot air outlet of the heating mechanism in the above-mentioned equipment and the conveyor belt is relatively far, when the heating mechanism blows the hot air to the conveyor belt, because the equipment has a large disinfection space for the conveyor belt, the hot air will dissipate in the disinfection space and it is difficult to blow accurately to the conveyor belt. At the same time, the hot air dissipated in the disinfection space will increase the heat in the disinfection space, causing the disinfection liquid sprayed by the spray mechanism to be dried by high temperature before it contacts the conveyor belt, which in turn leads to the problem that the conveyor belt disinfection mechanism of the equipment is designed unreasonable and the disinfection effect on the conveyor belt is limited.
