UHT high-temperature instantaneous sterilization machine

detailed explanation

Uht high temperature instant sterilizer is suitable for instant sterilization of liquid materials such as fresh milk, fruit juice, beverage, ice lolly, ice cream slurry, soy sauce, soybean milk, condensed milk, alcohol, etc., as well as fluid materials. The feeding and discharging of this equipment are both equipped with three-way valves, and the flow rate can be adjusted as needed, ensuring reliable use.

1、 Classification of UHT high-temperature instantaneous sterilization machine

1. According to the heating method, it can be divided into two heating methods: steam heating UHT high-temperature instantaneous sterilization machine and electric heating UHT high-temperature instantaneous sterilization machine;

2. From a material perspective, it can be divided into two types: stainless steel 304 and stainless steel 316.

2、 Working principle of UHT high-temperature instantaneous sterilization machine

The working principle of this UHT sterilizer is to preheat the material by pumping it into the hot and cold material heat exchange device of the sterilizer through a centrifugal pump. Then, the material is quickly heated to the sterilization temperature through a high-temperature bucket filled with high pressure and maintained for about 3 seconds before and after, and the microorganisms and enzymes inside are quickly killed. After the material is discharged from the high-temperature barrel, it is cooled by heat exchange with the cold material, usually at a temperature below 65 ℃.

If the temperature needs to be increased in the next process, it can be achieved by adjusting the angle type shut-off valve or circulation, etc. Otherwise, the discharge temperature can be reduced by connecting cooling water.

The discharge is controlled by the throttle valve of the sterilizer, which can keep the boiling point of the material above the maximum temperature while maintaining a certain pressure. During normal production, adjust this valve to generate back pressure control flow by overcoming spring pressure with the driving force of the pump. When cleaning and sterilizing the machine, it should be fully opened. The circulating storage tank can be used to prepare acid-base solutions and effectively clean the scale on the inner wall of the coil.

Due to the simultaneous use of stainless steel three-way plugs, the flow rate can be appropriately adjusted.

3、 Application of UHT high-temperature instantaneous sterilization machine

UHT high-temperature instantaneous sterilization machine, also known as high-temperature instantaneous sterilization, generally operates at a temperature of 115-135 ℃ and has a sterilization time of 4-10 seconds.

The uht sterilizer is suitable for instantaneous sterilization of liquid materials such as fresh milk, fruit juice, beverage, ice cream, ice cream slurry, soy sauce, soybean milk, condensed milk, alcohol, etc., as well as fluid materials.

4、 Characteristics of UHT high-temperature instantaneous sterilization machine

1. Continuous production with extremely short sterilization time.

2. Due to the short heating time, excellent products can be obtained.

3. Due to the use of high-temperature sterilization, the sterilization effect is good.

4. Used in series with centrifugal pumps or high-pressure homogenizers, it has a wide range of applications and is suitable for sterilizing high viscosity materials.

5. Due to the economic benefits of waste heat utilization in the design of heat exchangers with hot and cold materials, the steam consumption is low.
