In the fermentation industries, such like amino acids, glutamic acid, antibiotics, etc., the sterilized medium needs to be cooled promptly. However, for the used high-temperature water, which requires a large amount of cooling water and consumes a lot of water, it also requires auxiliary equipment such as chillers and cooling towers to cool down. Due to the large investment and high consumption of auxiliary equipment, that increases the cost of production, which is not conducive to energy conservation and environmental protection.Because plate heat exchangers have the advantages of high thermal efficiency, compact structure, convenient cleaning, disassembly and maintenance, easy to change the heat exchange area or process combination, and no dead ends of disinfection, the heat exchangers are now widely used by most manufacturers such as biological fermentation and heating.

Propellent plate heat exchanger is resistant to high temperature, high pressure and handles high viscosity, solid particles and fiber suspensions and other media. In the fermentation industry and distillation process, welded plate heat exchangers have broader application prospects than detachable plate heat exchangers.
