Sanitary Heat Exchanger

Working Principle

The material flows through the inside of the sanitary heat exchange tube, 

and the refrigerant or heat medium flows through the outside of the heat exchange tube in the opposite direction. The end of the heat exchange tube is fastened with double tube plates, and serves as a leakage monitoring point to prevent the two-way cross contamination of the material and heat exchange medium.

Double tubesheet structure: 

This series of heat exchangers adopt double tubesheet structure design, so that the tube side and shell side are connected by their own tubesheet respectively, breaking the traditional of tube heat exchangers, where the tube side and shell side share the same connecting tubesheet, so as to minimize the risk of cross contamination, facilitate the timely discovery of potential leakage, and ensure the safe production of users.

Full emptying design: 

the heat exchange tubes are 316L sanitary pipes with smooth surface, straight structure, no dead corners, convenient and thorough cleaning, and the lowest point of the equipment is equipped with an emptying valve, which is conducive to the emptying of materials, cleaning water and condensate after online sterilization. The full emptying design avoids dead corners at the product contact parts, prevents the growth of microorganisms, and is easy to clean and sterilize.

Material and surface treatment: 

this series of heat exchanger is made of 316L stainless steel, or the material required by customers. The roughness coefficient of the inner surface of the pipe in contact with the material is from 0.25 - 0.4 μ m.
