Abstract: An air flow chamber for cooking or chilling using alternating horizontal air flow has an air heating or cooling apparatus and an air recirculating flow control mechanism for forcing heated or cooled air through an enclosure wherein said air is alternatingly directed horizontally through said enclosure in a first cycle in one horizontal direction and in a second cycle in the opposite direction.

Abstract: A paint spray booth for painting articles is disclosed having a liquid wash scrubber beneath an upper chamber for removing the overspray paint particles from the air by intermixing the paint latent air with a liquid such as water. The scrubber forms a substantially horizontal water and air flow path to reduce the vertical height of the scrubber and therefore reduce the vertical height of the overall spray booth. The scrubber forms a trough extending longitudinally through the booth having a liquid flow exit from the bottom of the trough laterally from the bottom of the trough. Downstream from the trough, a baffle blocks the flow of the liquid forming a liquid trap to create turbulence in the liquid flowing through the scrubber to intermix the liquid with the paint latent air.

Abstract: A multi-product meat processing assembly (10) of the type for smoking meat includes a plurality of sequentially adjacent chambers (12,14,16,18,20,22) and trolley assemblies (26) for carrying meats hung from racks (24) through the chambers. An indexing mechanism (54) positions the racks (24) at predetermined positions within each of the chambers. The assembly (10) also includes telescoping doorways (74) separating the chambers. The assembly (10) further includes a reversible fan (132) for moving air in two directions through each of the chambers.

Abstract: An elongated meat processing system including an improved lifting mechanism for lifting products from a conveyor during conveyance through a treatment zone defined by a housing of the system so as to control the rate of advancement of the products and the time the products are present in the treatment zone. The system preferably includes a plurality of the conveyors arranged in a vertically spaced relationship with each of these conveyors being of a reciprocating type including a pair of laterally spaced reciprocating beams that carry product sticks on which the products are hung. The lifting mechanism includes laterally spaced lifters along the length of the system for lifting the products after forward reciprocation of the conveyor beams so the products are suspended and do not move rearwardly during subsequent rearward beam reciprocation. Prior to a subsequent forward reciprocation, the lifters return the products to the beams to provide product advancement.
