ABSTRACT:
The apparatus comprises a cage (rotatable in one direction) formed by roller brushes (rotatable in the opposite direction) radially arranged about a axis to define a sloped chamber. A fender is located along one side of each roller brush. A stationary tube, closed at both ends and having a motor-driven rotatable auger therein, extends through the chamber. The tube has four openings (proceeding from the high to the low end of the chamber): a top (supply) opening; a bottom (feed) opening; a top (recovery) opening; and a bottom (discharge) opening. Unhulled nuts from the supply opening are fed through the feed opening by the auger and form a single layer against the chamber wall and advance through the sloped chamber. During cage and roller rotation, each nut is trapped between a fender and the bristles in the outgoing quadrant of the adjacent roller brush and the hull is removed. Fully-hulled nuts, when they reach the 3 o'clock to 1:30 o'clock position of the rotating cage, fall through the recovery opening into the tube and are expelled from the tube through the discharge opening by the auger.
