Plate sterilizer introduction It is suitable for heating, sterilization, heat preservation and cooling of liquid beverage food such as fresh milk, fruit juice and wine. Using high precision products/water temperature control, product by the balance tank into the heat exchanger, the heat thermal material part and kill bacteria so cold material after heat transfer temperature reaches the preset value, and then through indirect heating by steam heating to the sterilization temperature, the material in the temperature in the tube to maintain the required temperature for a period of time for ultra high temperature sterilization,After coming out of the temperature holding tube, heat exchange is carried out with the cold material entering the machine, and finally it is cooled to the predetermined outlet temperature in the cooling section. The whole process is carried out in a closed state to ensure the biological stability of the material.And according to the user of the material heating, heat preservation, sterilization cooling of different technological requirements for specific combination system design, to meet all kinds of technological requirements.
