Abstract
A heat exchange device for powdery and granular materials configured to reduce adherence and accumulation of the materials and manufacturing time. The heat exchange device includes at least one substantially hollow disk-shaped heat exchanger among a plurality of heat exchangers that is disposed on the shaft about which the heat exchanger rotates. The hollow disc-shape heat exchanger includes a cutout recess part, plate surfaces extending from one side edge of the cutout recess part and forming a wedge-shaped plate surface, and a smoothly bulging projection formed at a central part of the heat exchanger. In addition, an opening is provided in the hollow disk-shaped heat exchanger at a tip end of the projection, and a shaft is inserted into the opening and joined to the hollow disc-shaped heat exchanger.
