A sanitary conveyor system is disclosed in which a conveyor bed, with or without curves, is mounted on a frame for movement of food trays between a plurality of work stations or movement of soiled trays from the cafeteria to the ware-washing area. A central box channel is mounted remote from the work stations and is provided juxtaposed to and below the pair of conveyor beds. The conveyor system includes a first set of pulleys being disposed adjacent to the tail end of the conveyor beds which are horizontally aligned and angled upwardly from the box channel to the conveyor beds such that each belt in the lower return flight path of the box channel are moved upwardly to the corresponding upper flight path of the conveyor bed. A second set of pulleys is disposed adjacent to the drive end of the conveyor bed and operatively connected to a belt drive unit such that belts are moved from the upper flight path of the conveyor bed to the lower return flight path of the box channel. Accordingly, in the lower return flight path, the belts are constrained within the box channel during their lower return flight path remote from the work stations.
