Abstract: An oat crimping device which is characterized by a housing fitted with a feed barrel and including a hopper located inside the housing for receiving raw oats to be crimped or processed. A pair of rotating, knurled drums are provided in the hopper and raw oats are fed from the feed barrel through top slots or openings in a feed auger tube to a rotating feed auger inside the feed auger tube, which feed auger distributes the raw oats through bottom slots in the feed auger tube, to the rotating drums for dispensing through the lower portion of the hopper into a collection container. Manual adjustment of the raw oat feed stream is accomplished by rotation of the feed auger tube to adjust the slots for dispensing the raw oats from the feed barrel to the feed auger crimping rollers.
