An elevated rack device for preparing food includes a base to which a plurality of uprights is attached. Each upright extends substantially perpendicularly from the base proximate to a first end of the base. A rack is attached to the plurality of uprights distal from the base and extends substantially colinearly with the base toward a second end of the base. A food item can be positioned on a top of the rack with surfaces of the food item being substantially accessible to a user and the food item being slidable from the rack.

A heat transfer device for thermal treatment of food items includes an enclosure defining an interior of the heat transfer device. A first and second driven conveyor systems are positioned within the enclosure. A first primary heater is arranged interior of the first chain conveyor belt. A first chain heater is arranged proximate to the first chain conveyor belt at a location of the first chain conveyor belt proximate to the opening. A second primary heater is arranged interior of the second chain conveyor belt. A second chain heater is arranged proximate to the second chain conveyor belt at a location of the second chain conveyor belt proximate to the opening.

The invention involves an electrical corn-on-the-cob roaster including a repository with a cavity having a structure that generally forms a plurality of cylindrical tubes for receiving a plurality of cobs of corn. In exemplary embodiments, a corn roaster assembly includes a cover concealing a heating element, a repository including a cavity defined by the heating element, a and a removable cage forming a plurality of cylindrical receptacles, each of the plurality of cylindrical receptacles configured to receive a cob of corn. To improve heating or roasting the cob of corn a polygonal, circular, or semi-circular configuration of heating panels may be disposed about a heating chamber so as to maximize heat for roasting the corn but minimizing heat on the casing or cover surrounding the heating element.
