Abstract
A plurality of axially spaced blades are rotated by a drive shaft positioned above the feed trough. The blades rotate transversely through the upper feed layer skimming off the foreign matter which is deposited in a container alongside the trough as the blades are rotated downwardly. Preferably, the blades are rotated through scraping wires on their downward track to clean the blades prior to passing through the feed once more.
