  • Patent number: 5027530
    Abstract: An apparatus (30) is disclosed for effective drying of material, such as vegetables, by centrifugal force. The apparatus (30) includes a series of conveyor assemblies (52-58) distributed on a rotating shaft (34). A gear ring (76) can be held stationary while the shaft rotates to move conveyor belts (70) within the apparatus to simultaneously load material to be dried while dried material is removed from the other end of the apparatus. When the conveyor belts are loaded, the shaft and conveyor assemblies can be rotated at a higher rotational velocity to dry the materials for a predetermined period of time.
