Description
Technical Field
[0001] The utility model relates to the technical field of sterilization for food processing, in particular to a sterilization device for powdered food. Background Art
[0002] Food sterilization is to kill and sterilize the main factors that cause food spoilage - microorganisms - to stabilize food quality, effectively extend the shelf life of food, and thereby reduce the number of surviving harmful bacteria in food, avoid human infection caused by the intake of live bacteria, or prevent human poisoning caused by bacterial toxins produced in food in advance.
[0003] For example, the authorization announcement number "CN220423096U" is named a sterilization device for powdered food. Although ozone can be transported to the sterilization chamber through the walls of the four guide tubes and blown out from multiple sterilization holes, it can directly sterilize powdered food from multiple angles and areas. However, the existing sterilization device for powdered food uses ozone and ultraviolet rays to achieve the sterilization effect when sterilizing powdered food. However, ultraviolet sterilization requires sufficient ultraviolet irradiation intensity and irradiation time to achieve the sterilization effect. At the same time, because ozone is not chemically stable enough, it is easier for ozone to undergo chemical reactions during sterilization, and then converted into other substances and can no longer play a sterilization effect. Therefore, the actual sterilization ability of the existing sterilization device for powdered food is relatively weak.
[0004] Meanwhile, the existing sterilization device for powdered food needs to sterilize the powdered food. The powdered food is easy to clump or be mixed with other debris during processing, so it is difficult to separate the clumps or sort out the debris during the sterilization process. Therefore, the powdered food that has been sterilized is prone to low cost and quality. Utility Model Content
