The principle of sterilization is that within a certain temperature range, the lower the temperature, the slower the bacteria reproduce; the higher the temperature, the faster the reproduction. But if the temperature is too high, the bacteria will die. Different bacteria have different optimum growth temperatures and heat and cold resistance. In fact, pasteurization is to take advantage of the characteristics of pathogens that are not very heat resistant, and treat them with appropriate temperature and holding time to kill them all. However, after pasteurization, a small number of harmless or beneficial, heat-resistant bacteria or bacterial spores are still retained.
During the continuous development of the pasteurization machine, some technologies are also continuously improving. The heating and cooling principles include compressors and water circulation. In contrast, water circulation is more efficient than compressors, and it retains the original flavor of milk and gradually replaced it. Compressor pasteurizers, water circulation pasteurizers are available in the market as mini, simple, luxury, cabinet, yogurt and milk all-in-one machines. With the continuous development of pasteurization technology, pasteurization, the number of sterilizers is also increasing.
The pasteurization machine on the market is mainly used for commercial purposes. At the same time, pasteurization is also an international universal sterilization standard. It is used by many large enterprises. The other flavors of pure milk on the market are pasteurized. With the development of green and healthy food at any time, pasteurizers are used in many small dairy farms, and small dairy farms use 100 liters or 200 liters, mainly for making fresh pure milk and distributing it to the market. . The pasteurization machine is equipped with a cold water circulation system. There are two general refrigeration methods. One is: compressor refrigeration. This refrigeration method is fast and effective. Another refrigeration method is cold water circulation refrigeration. The physical cooling method will be much lower in cost.
