DEFINITION

Classification: 99/521

(under subclass 520) Device wherein at least one of the plural hulling zones includes two or more hulling elements (one of which revolves about an axis) that cooperates to perform a hulling operation and these cooperating elements are not multi-perforated.

(1) Note. The hulling elements of this subclass may contain a single opening to allow grain to flow in or out, but are otherwise imperforate (they are usually of the "grinding stone" variety).
