    摘要: A device for the heat treatment of a product includes a housing, and a conveyor for conveying the product between an inlet of the housing and an outlet of the housing. The conveyor includes a screw which is mounted so as to turn in the housing according to a geometric axis of rotation and comprising an actuator for rotating the screw according to said axis, with ohmic heating of the screw. Accordingly, the housing comprises an envelope consisting of a refractory material through with the screw extends, said envelope being shaped in the form of a tube, the main inner surface of which follows contours of the screw.
