Abstract:
A unit was developed that separates onions from soil clods by the difference in their rebound trajectories, after bouncing on a rotating steel roller. The effect of the parameters was investigated in the laboratory with two modes of operation, forward and backward bouncing. Feeding velocity and impingement location on the roller were found to be very critical factors. At the proper combination of the parameters, good separation was obtained. A field unit based on two stages was operated successfully on an onion harvester.
