Properly tempered sorghum or other cereal grain is continuously metered by an auger in an axial direction into the center of the interior of a rotor where it is acted on by a flared textured cone to cause discharge into an independently rotating spreader having vanes which assure uniform distribution of the grain along the entire length of the interior of the rotor. The interior of the peripheral wall of the rotor has circumferentially-spaced axially-extending elements which guide the grain toward axial slots in the peripheral wall and which lead to a peripheral space between the rotor and a perforated stator wall where the grain is acted on by axial bars to promote cleavage of the grain and perform concomitant decortication and degermination, converting the endosperm tissues into particles of a desirable size and shape, free from attached seedcoat and germ tissues so that said particles are thereafter readily separable by known milling methods.
In milling apparatus having an outer housing, having a cylindrical stator supported in said outer housing, said stator having a perforated peripheral wall and there being an outer space between said outer housing and stator from which grain particles are adapted to be discharged, having a rotor and having means supporting said rotor for rotation on a horizontal axis within said stator, there being a milling space between said rotor and stator, and there being cooperating means on the interior of the peripheral wall of the stator and the exterior of the rotor for performing concomitant decortication and degermination in said milling space, the improvement comprising having the rotor hollow and provided with openings in its periphery communicating with said milling space, and means for feeding grain into the interior of said hollow rotor to be discharged from said rotor openings into said milling space.
