ABSTRACT:
A housing having propeller type fans in the housing adjacent to an object or objects to be dried. Shafts, carried by sleeves projecting through the side walls or top wall, rotate the fans. Motors externally of the housing drive the shafts.
In one form of the invention, the air circulated by the fans is heated by steam coils adjacent to the periphery of the blades of the fans. In another embodiment, an open flame gas or oil burner, disposed in a combustion chamber, heats air, which is subsequently directed by ducts to the fans. Exhaust blowers and exhaust ducts exhaust the fume laden air from the chamber. Still another embodiment shows pairs of juxtaposed oppositely blowing fans carried by shafts protruding through the walls of the oven and spaced heaters between the fans. Still another embodiment shows opposed fans for drying a cylindrical member passed through the chamber.
