Abstract: Cottonseed processing system includes a huller/separator combination. The huller assembly has a pair of counter-rotating, toothed rollers for shearing the seed hulls, with the shearing surfaces provided by removable segmented plates. The separator assembly is provided by a vertically disposed, angularly stepped, air duct with upwardly directed air flow separating the seed hulls from the seed meat products. A paddle wheel feeder assembly functions as an air lock between the huller assembly housing and the air duct.

Abstract: Cottonseed processing machinery has an automatic variable speed feeder. Cottonseed flows through a chute into a hopper and out of the hopper onto a gratefall adjacent turning saw blades. A curved section coextensive with the gratefall overlies the gratefall and urges the cottonseed toward the gratefall and saw blades. The sensing means of a switch detects movement of a weighted arm urging the curved section toward the gratefall. A float shaft is rotated between the gratefall and the curved section in the cottonseed roll. Pulleys drive one part of an electric clutch from the clutch shaft. The other part of the electric clutch when energized connected the first part to the speed reducer which in turn drives the feed roll shaft.
