ABSTRACT:
Grain is fed from a hopper to a horizontally oriented adjustable speed steam heated auger driven by a variable speed drive. The auger is long enough (approximately twenty inches) that temperature controlled steam fed to a plurality of inlets along the auger as related to the rate of grain movement through the auger heats the gain therein to approximately three hundred degrees Fahrenheit. Then it is dropped through a grain outlet opening into a high velocity cold air stream temperature shocking the hot grain causing a sudden contraction of grain outer layers causing them to crack and loosen from the grain core. The grain is then fed through tubes to space between a rotatable internally rubber (or soft plastic) sheet layer sheathed inner surface outer mill member fitted to and rotatable about a truncated cone member having outer surface metal channel members angled approximately forty five degrees adjacent at the top and diverging at the bottom. The grain is fed to and carried through a guide track with scrubber baffles and slightly corrugated along its length to an exit tube.
