ABSTRACT:
A sorting apparatus to remove sticks, weeds and other debris from a batch of peanuts and sort the peanuts into size categories. At least two longitudinally spaced apart sets of endless belts wrap over separate sets of drive rollers. The belts are interposed to position a belt from one set adjacent a belt from another set. The sets of belts travel at different speeds to move peanuts and debris into the longitudinal gaps between the belts. Debris, such as sticks and peanuts transverse to the belts are induced by the relative movement of the belts to align longitudianally into the gap between adjacent belts. Peanuts and debris smaller than the gap fall through into a hopper and larger peanuts and debris fall into a separate hopper. Larger debris falls off the end of the apparatus where the endless belts turn over a drive roller from a horizontal direction to a downward direction.
