A casing covers the conveyor, with a chamber provided between the inner surface of the casing and the outer side of the conveyor, and the casing surrounding the whole or a part of the circumference of the conveyor. Hot blast is supplied to the chamber. Blast pipes connected to the chamber blow the hot blast upon the upper and lower surfaces of the conveyor.
