The plate heat exchanger is a new type of high-efficiency heat exchanger made up of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat exchange is carried out through the plates. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. It has the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, long service life and so on. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, the floor space is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more.
Plate Type Heat Exchanger is composed of plate heat exchanger, balance tank, centrifugal sanitary pump, hot water device (including steam pipeline, hot water injection device), bracket and instrument box. Used for sterilization and cooling of milk or other heat-sensitive liquids. The materials to be processed first enter the balance tank, and are sent to the heat exchanger by the centrifugal sanitary pump, after preheating, sterilization, heat preservation, and cooling. Any material that has not reached the sterilization temperature will be reversed by the instrument controlled pneumatic return valve and then returned. The balance tank is reprocessed. The material sterilization temperature is automatically controlled and continuously recorded by the instrument control box to monitor and inspect the sterilization process. There are mainly two types of plate heat exchangers: frame type (removable) and brazed type. The plate forms are mainly herringbone corrugated plate, horizontal straight corrugated plate and knob-shaped plate.
