Sterilization method of pasteurization machine
The principle of sterilization is that within a certain temperature range, the lower the temperature, the slower the reproduction of bacteria, the higher the temperature, the faster the reproduction. But if the temperature is too high, the bacteria will die. Different bacteria have different Zui suitable for growth temperature and temperature and cold resistance. Pasteurization is actually the use of pathogens that are not very heat-resistant. They are treated with appropriate temperature and holding time to kill them all. However, after pasteurization, a small number of harmless or beneficial, heat-resistant bacteria are retained.
Sterilization method:
There are a wide variety of pasteurization procedures in use today. The “low temperature and long time†treatment is a batch process that is now used only by small dairy factories to produce some cheese products. The "high temperature short time" process is a flow process, usually carried out in plate heat exchangers, and is now widely used in the production of drinking milk. The product obtained by this method is not sterile, i.e. still contains microorganisms, and requires refrigeration during storage and handling. "Quick pasteurization" is mainly used in the production of yogurt dairy products. There are two main types of pasteurization methods adopted internationally:
One is to heat the milk to 62-65 degrees for 30 minutes. Using this method, it can kill various growth-type viruses in milk, and the sterilization effect can reach 97.3~99.9%. After disinfection, only some of the phage and heat-resistant bacteria and spores remain, but most of these bacteria It is a lactic acid bacteria, which is not only harmless to humans but also good for health.
The second method heats the milk to 75 to 90 degrees and keeps it for 15 to 16 seconds. The sterilization time is shorter and the work efficiency is higher. However, the basic principle of sterilization is that the pathogen can be killed, and the temperature is too high, but there will be more nutrient loss.
