yogurt milk fruit jam juice sauce Pap sterilization machine Pasteurizer
Pasteurizer is composed of inner layer, jacket, insulation layer, outer cover, reducer, mixing slurry and thermometer. It has the advantages of convenient operation, corrosion resistance, strong production capacity and convenient cleaning.
Principle of pasteurization
In a certain temperature range, the lower the temperature, the slower the bacterial reproduction; the higher the temperature, the faster the reproduction. But when the temperature is too high, the bacteria will die. Different bacteria have different optimum growth temperature, heat and cold resistance. Pasteurization is the use of pathogens is not very heat-resistant characteristics, to kill all pathogens with appropriate temperature and heat preservation time treatment.
There are two pasteurization process commonly used:
1.to heat the milk to 62 ºC - 65 ºC and keep for 30min. This method can kill all kinds of growth type pathogenic bacteria in milk, and the sterilization efficiency can reach 97.3% - 99.9%. After disinfection, only a part of thermophilic bacteria, heat-resistant bacteria and spores are left, but most of these bacteria are lactic acid bacteria, which are not only harmless to people, but also beneficial to health;
2. to heat the milk to 75 ºC - 90 ºC and keep for 15s-16s, which can shorten the sterilization time More efficient.
The basic principle of sterilization is that just kill the pathogen will be alright , if the temperature is too high, there will be more nutrition loss.
Application:
Pasteurization is mainly a sterilization method for milk, which can not only kill the pathogenic bacteria harmful to health, but also make the milk quality change as little as possible. Pasteurization cannot kill all bacteria, it can only reduce the number of pathogens to a level that will not cause harm to consumers. Besides milk, pasteurization can also be applied to fermented products
Pasteurization tank can be used as detoxification tank, mixing tank, temporary storage tank, batching tank, etc. Pasteurization tank is widely used in dairy industry, food, pharmaceutical, chemical industry, beverage and other industrial sectors. As a necessary equipment for heating, cooling, heat preservation, sterilization treatment or slurry storage, pasteurization tank is especially suitable for pasteurization and heat preservation of milk.
