The pasteurizer consists of plate heat exchanger, balance tank, pump, hot water
circulation system (including mixer of steam and water, hot water pump, steam adjusting valve and water level control) and computer system for pasteurisation
program, CIP program, and temperature control. It is used in heating and cooling raw material. The pasteurizer is usually used in the process of milk, ice-cream, milk powder, fruit juice, and beverage, which is sensitive to heat. The material is pumped to the plate heat exchanger, then undergone preheating, holding, heat energy recover and cooling, which can keep the products original physical nature and taste. If the temperature is below the set degree, this is sensed by a temperature transmitter. A signal activates flow diversion valve and the material flows back to the balance tank, then the material is pasteurized again. The state of the pasteurization temperature is recorded on a disc of the recorder in process of pasteurization.
