A more efficient combined husking and polishing action is accomplished by providing a rotor comprising a plurality of cam-like abrasive discs spaced apart by a corresponding plurality of spacer rings having a diameter smaller than that of the discs so as to form grain expansion chambers therebetween, whereby an energetic husking action followed by a moderate abrading polishing action are effected along the treatment chamber.Field of SearchWith disjoining hull from grainBy projecting grain against surface With means to vary spacing between hulling surfaces Directing gas adjacent hulling zone Internally and externally of hulling zone By valved gas passages With screen to separate products By hulling means Moving perforated surface With nonperforated hulling surface area Cylindrical or conical perforated enclosure With axially extending nonperforated hulling portion With additional hulling surface characteristics on enclosure Integral with moving hulling member With discharge control By plural hulling zones Serial zones Axially spaces zones With interior partition By rotating surface Enclosing a rotating, yieldably hulling element Adjustably or yieldably mounted hulling surface Radial hulling surface Relatively moving adjacent surfaces From plant material Outer covering, e.g., shell, husk, etc. By abrading | |
