Working principle of pasteurization

In a certain temperature range, the lower the temperature, the slower the reproduction of the strain; the higher the temperature, the faster the reproduction (the suitable temperature for general microbial growth is 28-37), but if the temperature is too high, the strain will die, and different strains have different suitable growth temperatures and heat and cold resistance. Pasteurization actually uses the fact that pathogens are not very heat resistant, they are treated at the appropriate temperature and holding time to kill them, but after pasteurization, a small amount of harmless, beneficial, heat-resistant bacteria or bacteria spores remain.

　　Pasteurization lineAlso known as pasteurizer, it can be used with elevators, conveyors and air dryers to form a continuous assembly line. Pasteurizer is a new product successfully developed by our company, which absorbs foreign technology and combines the production process requirements of domestic food, beverage, medicine and other industries.

　　Pasteurization lineOperation skills

Many milk drinks have the word "pasteurized" on their outer packaging, and TV advertisements often promote the use of "pasteurized" products.Pasteurization lineSafer, more nutritious and better to drink! So how does pasteurization work? That is, pasteurization lines are used for operations.

So,Pasteurization lineAs we all know, the strains reproduce slowly at low temperatures and reproduce quickly at high temperatures, but when the temperature is high enough, the strains are killed! We often boil water at home, that is, we use high temperature to kill the bacteria in the water, so as to prevent the bacteria from harming people. However, milk is different from water. If milk is heated to 100, its properties will change, nutrients will be lost, and flavor and taste will also change.

　Pasteurization lineThe advantage is that it can not only sterilize, but also reduce the loss of nutrients to the greatest extent, and ensure the flavor and taste of the beverage. However, due to the lack of sterilization, a small amount of harmless or beneficial heat-resistant bacteria and bacterial spores remain in the beverage. Therefore, the pasteurized beverage needs to be stored in a low temperature environment of about 4 degrees, with a relatively short shelf life and a length of about half a month.

　　Pasteurization lineThe structural characteristics

　Pasteurization lineThe work of the air temperature controller is to convert the set PU value (I .e. pasteurization unit, the sterilization effect caused by 1 minute at 60 degrees into pasteurization unit, I .e. a PU value) into the actual control air temperature curve of the water tank in each air temperature zone. By detecting the air temperature and controlling the air temperature change in each temperature zone, the main drive motor drives the upper and lower conveying chain network, which is divided into two temperature zones and three temperature zones, preheat the product step by step.
