An automated material processing system includes a frame having a longitudinal axis and a gantry movable along the longitudinal axis of the frame; a first belt extending along the longitudinal axis and moving about a cavity having a cavity opening within the gantry. A second belt supported by the gantry extends across the frame in a cross-frame direction perpendicular to the longitudinal axis and covering at least a portion of the cavity opening. A material treatment system to treat a material extends across at least a portion of the first belt and a portion of the second belt, and a vacuum system movable with the gantry and operatively connected to a manifold adjacent to both sides of the cavity opening.
