Abstract
Abstract A rotatable platform rotatably mounted in a refrigerated compartment is adapted to support a plurality of chunks of meat thereon. An arm in the refrigerated compartment is in operative proximity with the platform and mounted to sweep chunks of meat off the platform. A meat grinder in the refrigerated compartment below the platform catches and grinds chunks of meat swept off the platform. The meat grinder has an output opening formed through its bottom, whereby meat ground by the meat grinder is provided at the output opening. A drive in the refrigerated compartment coupled to the platform and the meat grinder rotates the platform and operates the meat grinder to grind meat supplied to it. A patty member is placed in the refrigerated compartment beneath the output opening of the meat grinder, whereby ground meat at the output opening is dropped onto the patty member. The patty member has an upper surface and a plurality of depressions formed in the upper surface. A leveling device in operative proximity with the upper surface of the patty member moves ground meat on the upper surface into the depressions and levels the surfaces of the meat in the depressions coplanarly with the upper surface. A grill in a heating compartment grills the meat in the depressions of the patty member. A transport device in the refrigerated compartment transports the patty member through the refrigerated compartment and into the heating compartment. A transport device in the heating compartment transports the patty member through the grill in the heating compartment.
