The working principle of fresh milk pasteurization machine is in a certain temperature range, the lower the temperature, the slower the bacterial reproduction; The higher the temperature, the faster the reproduction. But get too hot, and the bacteria die. Different bacteria have different optimum growth temperatures and heat and cold tolerance. In fact, pasteurization is the use of pathogens are not very heat-resistant characteristics, with appropriate temperature and holding time treatment, to kill all of them, but after pasteurization, still retain a small number of harmless or beneficial, relatively heat-resistant bacteria or bacterial spores.
In the process of continuous development of fresh milk pasteurization machine, some technologies are also improving. There are two kinds of heating and cooling principle: compressor and water cycle. In contrast, water cycle is more efficient than compressor, and it retains the original flavor of milk, gradually replacing the compressor pasteurization machine. The category of water cycle pasteurization machine on the market has mini type, simple type, luxury type, cabinet type, yogurt milk machine and so on. With the continuous development of pasteurization process, the types of pasteurization machine are also increasing.
