  • Patent number: 5024148
    Abstract: A device for removing coatings from granular materials such as hull-encased meats of grains. The device includes a housing within which is journaled a rotatably disposed drum. A wall is also mounted within the housing, the wall angling downwardly and being spaced at a distance from an outer surface of the drum to define a processing space therebetween. Typically, the processing space narrows downwardly within the housing. The drum is disposed for rotation so that any material fed into the housing through a hopper mounted on the top thereof will be drawn along the drum surface into the processing space. The processing space narrows sufficiently so that an abrasion is effected upon the material as it is deposited within the processing space because of the relative movement of the outer surface of the drum and the downwardly extending wall.
