ABSTRACT:
Crop drying apparatus comprises a horizontal rotatable drum divided internally into a plurality of outer chambers for containing crop to be dried, and a central, axially-extending, multi-sided duct which receives an axial air flow. The inner surface of each chamber has a perforate area to permit flow of air from the duct into the chamber to dry the crop therein and the outer surface of each chamber has a perforate area to permit discharge of moisture-laden air from the chamber to the surrounding atmosphere, the inner perforate area of each chamber leading the associated outer perforate area in the normal direction of rotation of the drum. Control flaps are provided to control the air flow through the inner perforations during rotation of the drum.
