Abstract
A food preparation device may include a tunnel cavity having a prep portion and a cooking portion, a conveyor belt extending through a length of the tunnel cavity, a cooking controller operably coupled to the prep portion and the cooking portion to selectively distribute power to at least a radio frequency (RF) capacitive heating source and a cold air source in the prep portion and at least a heat source in the cooking portion, and an interface panel. The prep portion and the cooking portion are positioned in a linear series in the tunnel cavity. The RF capacitive heating source comprises a ground plate and an anode plate.
