Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of milk processing, in particular to a pasteurization device. Background Art
[0002] Pasteurization is a method that uses a relatively low temperature to heat food within a specified time to kill the vegetative bodies of microorganisms. It is a method that can achieve the purpose of disinfection without damaging the quality of food. The process is to heat the mixed raw materials to 68-70°C, maintain this temperature for 30 minutes, and then rapidly cool them to 4-5°C. The principle is that the lethal points of general bacteria are all at a temperature of 68°C and a time of less than 30 minutes, so after the mixed raw materials are treated by this method, the pathogenic bacteria and most of the non-pathogenic bacteria in them can be killed. The mixed raw materials are suddenly cooled after heating, and the rapid changes in heat and cold can also promote the death of bacteria.

Therefore, we propose a new type of pasteurization device. Utility Model Content
