Plate heat exchanger is a new type of high efficiency Heat Exchanger which is stacked by a series of metal pieces with certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. Plate Heat Exchanger is an ideal equipment for heat exchange of liquid-liquid and liquid-steam. It has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, long service life and so on.
In the case of the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, the area is one-third of the tubular heat exchanger, and the heat recovery rate can be as high as 90%. Plate Heat EXCHANGER (Plate Type Heat Exchanger), the complete set of equipment by plate heat exchanger, balance groove, centrifugal sanitary pump, hot water device (including steam pipe, hot water injector), bracket and instrument box, etc. For sterilization and cooling of milk or other heat-sensitive liquids. To deal with the material first into the balance groove, through the centrifugal sanitary pump into the heat exchanger, after preheating, sterilization, insulation, cooling sections, where not to reach the sterilization temperature of the material, by the instrument control pneumatic reflux valve commutative, and then back to the balance groove reprocessing. The material sterilization temperature is automatically controlled and continuously recorded by the Instrument control box in order to monitor and inspect the sterilization process. This device is suitable for pre-sterilization and pasteurization of milk. The type of plate heat exchanger mainly has frame type (detachable type) and brazing type two categories, the plate form mainly has the glyph corrugated plate, the horizontal straight corrugated plate and the tumor-shaped plate three kinds.
