It can be used in aseptic heat treatment system of liquid beverage and food, using high-precision product/water temperature difference control. It rises to the predetermined value, and then is indirectly heated to 120 ℃ by water heated by steam. The material is maintained at the required temperature in the temperature holding tube for a period of time for ultra-high temperature sterilization. The heat exchange is finally cooled to the predetermined outlet temperature in the cooling section, and the whole process is carried out in a closed state to achieve the purpose of ensuring the biological stability of the material. According to the user's different process requirements for material heating, heat preservation, sterilization and cooling, a specific combined system design can be carried out to meet various process requirements.
1. Both the material and the heating medium are heated through non-contact heat exchange in their respective sealed systems to ensure the hygiene and safety of the material; 2. The sterilization time is short, which can ensure that the nutrients of the material are not destroyed; 3. The whole machine is made of food-grade stainless steel to ensure that it meets the national safety and hygiene requirements for beverage and food equipment; 4. Good heat transfer effect, high heat recovery rate and low energy consumption; 5. The main control components, valve parts and accessories are all imported parts, and the service life is long; 6. PLC control is adopted, which can automatically control the heating temperature, hot water temperature, steam flow adjustment, etc. of each section of the material, and is equipped with an automatic material return system to ensure that 100% of the material achieves sterilization effect; 7. Simple structure, easy to clean, easy to operate and low maintenance cost.
