Abstract:
A continuous conveyor transports food products in, through and out of a rectangular freezing vault containing a blower and a refrigeration coil. The conveying strand is made up of a series of individual plates attached outwardly of the chain connecting the plates and is free to flex in only one direction. Within the vault the conveyor travels about two parallel elongated spiral networks, each including two vertical shafts supporting a stacked array of rotating sprockets. A crossover strand connects the two networks at the base of two adjacent shafts and a second crossover strand connects at the top of the opposite pair of shafts. The top crossover strand is brought outside the vault and there travels about a driving sprocket and an idler forming an outside loop enclosing a work table for performing operations on the products. The outside loop traces out an asymmetrical geometrical figure having two parallel sides, with the driver located at the acute angle formed therein. The driving sprocket can be sized independently of the other sprockets over which the conveying strand travels within the vault. The vault itself is divided into two chambers, one a vestibule through which the products travel as they enter or exit the vault, and serving to isolate the second chamber from the outside air. The second chamber contains the conveyor networks, the blower and refrigeration coil. The cooling is accomplished by circulating the air within the compartment in a direction transverse to the paths over which the conveyor travels. Deflection systems are employed to insure complete distribution and effective cooling of the products. The blowers and refrigeration coil are located above the conveyor networks along substantially the entire length of the conveyor networks.
