Abstract
A conveyor is provided comprising an endless conveyor chain, a plurality of spacers, and at least two conveyor supports mounted on opposite sides of the spacers to permit air to freely flow therethrough. Each conveyor support comprises at least one elongate member mounted to any of a second plurality of spacers and any other elongate members to permit air to freely flow therethrough as well. Further, each elongate member has both inner and outer surfaces, and both top and bottom edges adapted to support the endless rolling conveyor chain from below. The inner surfaces of the elongate members are sloped and the outer surfaces of the elongate members are preferably substantially vertical to enhance downward movement of particulates. The top and bottom edges of the elongate members preferably include UHMW wearstrips to reduce friction. The conveyor may include guide rails to guide articles being transported along the conveyor, and a stop mechanism for stopping articles being transported at a predetermined position along the conveyor.
