An object of the present invention is to provide a heat exchange device for a powder and granular material, which is capable of suppressing an object to be processed from adhering/accumulating, and reducing the number of manufacturing processes (time), while keeping high heat efficiency, piston flowability and other advantages of a conventional device that uses wedge-shaped hollow rotating bodies. In order to achieve this object, a heat exchange device for a powder and granular material according to the present invention is configured such that at least one of a plurality of heat exchangers 30 to be disposed on a shaft 13 is formed as a substantially hollow disk-shaped heat exchanger in which a cutout recess part 31 directed from a circumferential edge of the heat exchanger toward a center of the same is provided; plate surfaces extending from one side edge 31a of the cutout recess part to another side edge 31b of a following cutout recess part are formed into a wedge-shaped plate surface 32 by gradually increasing a distance between the plate surfaces; a projection 33 that smoothly bulges in a horizontal direction as viewed from the side is formed at a central part of the heat exchanger; and an opening 34 is formed at a tip end of the projection, and the heat exchanger is disposed on the shaft by inserting the shaft into the opening.
