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 area is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more.
The Plate Type Heat Exchanger (Plate Type Heat Exchanger) is composed of a plate heat exchanger, a balance tank, a centrifugal sanitary pump, a hot water device (including a steam pipe, a hot water injector), a bracket, and an 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. For materials that have not reached the sterilization temperature, the pneumatic return valve is controlled by the instrument to change the direction and return The balance tank is reprocessed. The material sterilization temperature is automatically controlled and continuously recorded by the instrument control box to monitor and check the sterilization process. There are two main 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.
