The Hot Air Dryer with KHLT Recirculation is a convective heat exchange system for drying various types of products, mainly fish meal. The system consists of two closed and different air recirculation circuits: one is the drying air flow, which comes into direct contact with the product, and the other is a hot air flow, originating from the heat generator. The drying air enters into direct contact with the product by means of a rotating drum calculated by the air flow and by the residence time of the product inside the drum. The drying air is heated by hot air through a multitubular heat exchanger.
