Abstract

Abstract Meat processing apparatus including an elongate enclosure having an inlet end and outlet end with a plurality of treatment zones defined therein. A plurality of walking beam conveyors are mounted in the enclosure and extend from the inlet to the outlet end and are movable between a retracted position in the direction of the inlet and an extended position in the direction of the outlet. Lifting means are located in each treatment zone for lifting meat and similar products from the conveyors prior to a retraction movement of the conveyors, and to subsequently return the products onto the conveyor prior to an extension movement of the conveyors to cause the products to advance toward the outlet end and to control the time required to advance the products through each treatment zone. A plurality of transverse partitions define the end walls of the treatment zones, and an opening in each of the partitions permits movement of products into and out of the treatment zones by the walking beam conveyors. A door is mounted on each partition for movement between opened and closed positions with respect to the opening. The partitions are formed with slots for slidably receiving the walking beam conveyors and permitting the reciprocation of the walking beam conveyors in any position of the doors.
