Stainless Steel Plate Heat Exchangers

Hygienic solution for the food industry

Stainless steel plate heat exchangers are used in the food industry and prevent problems such as bacterial growth. Unlike conventional plate heat exchangers, they ensure hygienic heat transfer, which explains their popularity in the food processing industry. These systems are primarily used for heating and cooling milk and other food products.

Operating principle

Un échangeur de chaleur à plaques se compose essentiellement de deux orifices d'entrée, de plaques de transfert de chaleur à canaux et de deux orifices de sortie. Le rôle des plaques à l'intérieur du serpentin est de transférer la chaleur du fluide caloporteur au fluide chauffé sans les mélanger. La structure canalisée de ces plaques permet au fluide de circuler avec une forte turbulence, engendrant une distribution de chaleur plus uniforme et donc un transfert de chaleur plus efficace.
