The Principle Of Flush Grid Conveyor Belt For Sterilization Machine

The principle of Flush Grid Conveyor Belt for sterilization machine: plastic mesh belt sterilization, mainly for low temperature sterilization. The goal of sterilization is to reduce the number of bacteria to one hundred thousandth. At a certain temperature, the heating time is the bacteria D at this temperature. 5 times the value. After sterilization, the bacteria in the milk are not completely killed. It still needs to be refrigerated after sterilization. Even in the refrigerated condition, the remaining bacteria will grow slowly. The so-called shelf life of the pasteurized milk, It's actually the time before these bacteria grow to a certain amount. Normal temperature milk is kept at an ultra-high temperature (usually above 135 degrees Celsius) for one or two seconds, that is, its heating time is at least 12 times the D value at that temperature. One of the important health indicators in raw milk is the total number of colonies. The current EU standard is less than 100,000 / ml, and in fact, if the total number of colonies exceeds 300,000 / ml, Roller Top Belt can not be processed into Pap milk.

The working principle of the pasteurization machine is to take advantage of the fact that the bacteria are not very heat-resistant. One is to heat the milk to 62~65°C for 30 minutes, and the sterilization efficiency can reach 97.3%~99.9%. Some thermophilic bacteria and heat-resistant bacteria and spores, etc., but most of these bacteria are lactic acid bacteria, which are not only harmless to humans but also good for health. The second method heats the milk to 75-90 ° C and keeps it for 15-16 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. The working principle of the pasteurization machine is to electrically heat the water in the water tank, and then the water passes through the heat sterilization layer of the sterilization layer of the sterilization tank to heat the fresh milk in the milk tank to achieve the purpose of sterilization. Simply put, the working principle of the pasteurizer is 85 degrees low temperature heating to achieve sterilization.
