Process flow:
Pasteurization machine is the temperature controller set PU value to convert into the actual control temperature curve of the water tank in each temperature zone, in order to accurately control the temperature change of each temperature zone through temperature detection. The main drive motor drives up and down the two layers of the bottle chain network will once the material through three temperature zone step by step heating preheating, and two temperature zone sterilization and three temperature zone step by step cooling and cooling process.
Pasteurization machine in the process of the development of some technology is also in constant progress, principle of heating and cooling compressor and two kinds of water circulation, compared with the water cycle than high efficiency compressor, and retained the flavor of milk, pasteurized machine gradually replaced the compressor, the category of the water cycle pasteurization machine on the market have a miniature, simple type, luxury, types such as cabinet, yogurt milk machine, with the continuous development of pasteurization process, pasteurization machine of the species are also increasing.
Milk sterilization is to treat fresh milk at 62-65℃ for 30 minutes, or treat it at nearly 100℃ for 15 seconds. The method can eliminate pathogenic microorganisms and some enzymes due to low disinfection temperature; Less damage to the nutrients in milk, so can maximize the preservation of milk nutrients and some of the beneficial bacteria, such as lactobacillus. But pasteurized milk requires "cold chain technology." Storage, transportation, sales and drinking should be controlled under the condition of low temperature refrigeration, which is difficult to preserve. Generally, it is mainly stored in plastic bags, glass bottles or freezers.
