ABSTRACT:
An apparatus for cleaning grain and the like by gravity feeding through a casing having within it a central zig-zag chute with top-hinged screens resting across openings in each underside of each zig and each zag of the chute, the action of the grain itself resonating the screens for increased agitation. A large access door to the edge of the screens permits each inspection and replacement as the screens are hinged by means of a top strip which slides into an open-ended slot at the knee of each zig and each zag.
