  • Patent number: 5354230
    Abstract: A food processing system (10) includes a first conveyor (12) having sprocket driven chains (14 and 16) extending along a loading run (26) and a return run (28) at a loading station (80). A support bar (52) extends transversely between the chains (14 and 16), and has a first movable hook (62) and a second stationary hook (64) mounted thereto. A food stick (74) for supporting a food product (76), such as a string of hot dogs, has a leading end (72) engageable with the movable first hook (62) for manually pushing the first hook along the support bar, and a trailing end (82) engageable with the stationary second hook. A second conveyor (102) at a transfer station (114) has spaced parallel sprocket driven chains (104 and 48) for transporting the food stick (74) and food product (76) to a processing station for cooking, smoking, chilling, etc.

  • Patent number: 5244683
    Abstract: An apparatus and method for processing a food product. A series of processing cabinets are each provided with an inlet and an outlet in one of the cabinet side walls adjacent an end wall. The product is carried by a series of individual product carriers, which are capable of turning relative to the rail. The carriers pass through the cabinet inlets, and are turned relative to the rail thereafter so as to pass through the cabinets in a closely packed arrangement. As the carriers approach the opposite end wall of the cabinet, the carriers are again turned so as to exit the cabinet in a direction perpendicular to the longitudinal axis of the cabinet.
