The detachable plate heat exchanger is made up of many stamped corrugated metal plates at a certain interval, sealed with gaskets around them, and laminated and compressed by a frame and a compression screw. As more and more industries adopt plate heat exchangers as intermediate heat exchange systems, the market for plate heat exchangers has become more and more marketable. In addition to the commonly used civil, chemical, power plant and shipbuilding industries, the food industry is also a very large market. Plate heat exchangers are especially used in the field of milk pasteurization. What is the difference between plate heat exchanger and plate sterilizer?
(1) The similarities between plate heat exchanger and plate sterilizer
The appearance is in the form of a plate heat exchanger, and the gaskets and heat exchanger plates inside are the same as the plate type.
(2) The difference between plate heat exchanger and plate sterilizer
a. Gasket requirements. Because it is the food industry, the production standard of gaskets must be food-grade.
b. Frame bolts. The plate type sterilizer is made of stainless steel.
c. Segmented. Because the pasteurization process is different from the conventional plate type process, the plate type sterilizers are divided into multi-stage. The three-stage type (the first stage sterilization stage, the second stage heat recovery stage, and the third stage cooling stage) is commonly used, and there are also 5-stage types, which are used for ultra-high temperature sterilization.
