DEFINITION

Classification: 99/522

(under subclass 520) Device including two or more hulling elements that each have plural apertures therein and each element revolves about its own respective axis.

(1) Note. At least one multi-perforated surface participates in the hulling operation; however, one or more of the multi-perforated surfaces may serve only as a "screen", as in subclass 528. Also, the plural axes may be collinear, or angularly related, or a combination of both.
