ABSTRACT:
In a drying oven having plural superposed endless belts on which material to be dried, such as fruit, moves in a circuitous path from top to bottom, excessive drying of the material on the lower belts is prevented, by directing hot air toward the upper belts but a mixture of hot air and relatively cool outside air toward the lower belts. Adjustable shutters for the inlet air, and for the division between the two portions of the hot air, are provided, there being separate fans for the two air streams.
