UHT sterilization machine is a kind of equipment that uses high temperature to process food. It can raise the temperature to above 135 ℃, and kill all the bacteria, yeast, mold and other microorganisms in the food in a relatively short time, so as to effectively extend the preservation time of the food and maintain the original taste and nutrition of the food. Here we introduce the working principle of UHT sterilization machine. The

UHT sterilizer heats the raw material liquid to above 80°C through a device called a preheater. This process is designed to reduce the microbial activity in the food and prepare for subsequent high-temperature treatment.

Next, the food enters the heating zone of the UHT sterilizer. The temperature of the heater is quickly adjusted to above 135°C, and the food needs to stay at this temperature for a few seconds or more to further kill microorganisms. This process is called ultra-high temperature treatment (UHT), which can kill almost all microorganisms and make food shelf life for months or years.

In addition, UHT sterilization machine in ultra-high temperature treatment, but also through a rapid cooling process, this process is designed to avoid excessive temperature damage to the food, but also to avoid bacteria in high temperature conditions to grow again, the temperature dropped below 20 ℃, sterilization is completed.

In general, the high-temperature treatment technology of UHT sterilizer can effectively kill bacteria and other microorganisms in food, while maintaining the original taste and nutritional content of food. Compared with the traditional sterilization equipment, UHT sterilization machine is more efficient, can greatly shorten the sterilization time, improve production efficiency, is one of the essential equipment in the modern food industry.

In our daily life, we often find bagged or bottled juices, dairy products, soy milk and other beverages. They have been treated with high temperature by UHT sterilizer, which can ensure the freshness and hygiene of the products, and it is for our health and Convenience has created countless delicious foods.
