1. A conveyor system comprising:
a woven-wire belt assembled from interwoven helically-wound spirals and connector rods, a pair of connector rods being associated with each helically wound spiral to define open-access recesses of uniform cross-sectional configuration and dimension, said recesses extending in uniformly spaced locations across a width of said belt; and
at least one rotatable member including an outer cylindrical surface symmetrically disposed relative to a central axis of rotation of said member and a plurality of spaced, uniformly radially-oriented protrusions on said outer cylindrical surface for engaging said open-access recesses of said woven-wire belt, each of said protrusions including a parallelogram-shaped body substantially corresponding to the cross-sectional configuration and dimension of correspondingly-located recesses of said woven-wire belt;
wherein said at least one rotatable member includes a hollow tubular member and the outer cylindrical surface of said at least one rotatable member includes a plurality of openings into an interior of the hollow tubular member.
