The material enters the outer flow channel of the double-set coil through the feed pump, and the hot material flowing out of the inner layer is indirectly heated to get preheated. When the material enters the high-temperature coil set in the high-temperature barrel, the steam in the barrel is indirectly heated. It is heated to the required sterilization temperature, and then kept in the single coil outside the barrel to kill the bacteria of the material. When returning to the double coil, the material enters the inner flow channel and is absorbed by the outer cold material. Cooling, so that the discharge temperature is significantly reduced (generally lower than 65 ℃). If the process needs to increase or decrease the discharge temperature, the angle-type shut-off valve can be activated to connect the heat source (steam) or heat source (water or ice water, etc.) to the outer flow channel at the lower end of the double sleeve. The throttle valve of the ultra-high temperature instant sterilizer can be adjusted. On the one hand, the material is maintained under a certain pressure and its boiling point temperature is increased to prevent vaporization; on the other hand, it is also used to adjust the flow rate. The material is finally removed by the three-way cock. The lower end of the cock is connected to the spiral tube, and the outlet of the plug will be the storage tank. When necessary, the spiral tube can be rotated to align with the overflow tube. The upper end of the feed tee cock is connected with the storage tank, and the lower end is connected with the material source pipeline

Classification of ultra-high temperature instant sterilizer:
1. According to the heating method, it is divided into two heating methods: steam heating UHT sterilization machine and electric heating UHT sterilization machine;
2. According to the material angle, it is divided into two materials: stainless steel 304 and stainless steel 316

Working principle of ultra-high temperature instant sterilizer
Also known as UHT, UHT sterilizer, the working principle of the sterilizer is that the material is preheated by pumping the material into the heat exchange device of the cold and hot material in the sterilizer by a centrifugal pump, and then the material is quickly heated to sterilization through a high-temperature barrel full of high pressure The temperature is maintained for about 3 seconds before and after, the microorganisms and enzymes in it are quickly killed. After the material leaves the high-temperature barrel, it is cooled by heat exchange with the cold material, and the temperature is generally lower than 65°C. If the next process needs to increase the temperature, it can be achieved by adjusting the angle shut-off valve or circulation, and vice versa, by connecting cooling water to reduce the discharge temperature. The discharging is controlled by the throttle valve of the sterilizer, this valve can make the boiling point of the material higher than the maximum temperature while maintaining a certain pressure. Adjust this valve during normal production, and the back pressure control flow is generated by the driving force of the pump to overcome the spring pressure. It should be fully opened when cleaning the sterilizer. The circulating storage tank can be used to prepare acid and alkali solutions to effectively clean the scale on the inner wall of the coil. Due to the use of stainless steel three-way cock at the same time, the flow can be adjusted appropriately.

use
Also known as ultra-high temperature instant sterilization, the temperature is generally 115-135℃, and the sterilization time is 4-10 seconds. The sterilizer is suitable for the instantaneous sterilization of liquid materials such as fresh milk, fruit juice, beverages, popsicles, and ice cream slurry, soy sauce, soy milk, condensed milk, alcohol, etc. It can also be used for the sterilization of fluid materials.

Features
1. Continuous production, extremely short sterilization time.
2. High-quality products can be obtained due to the short heating time.
3. Due to the ultra-high temperature sterilization, the sterilization effect is particularly good.
4. Used in series with centrifugal pump or high-pressure homogenizer, it has a wide range of applications and is suitable for the sterilization of high-viscosity materials.
5. Because the heat exchanger with cold and hot materials is designed to have the economic effect of waste heat utilization, the steam consumption is small.

connection. When the processing capacity needs to be improved, the "U"-shaped pipe can be removed and a centrifugal pump can be connected. This ultra-high temperature instantaneous sterilizer is a hand-controlled sterilizer. The sterilization temperature is adjusted by the angle type shut-off valve, and the discharge temperature is made of stainless steel 304
