Abstract
An emitter tube has an outer surface and an inner surface, wherein the inner surface defines a cavity of the emitter tube, and the cavity of the emitter tube is adapted for receiving food. An outer tube has an inner surface that defines a cavity of the outer tube, and the emitter tube is positioned in the cavity of the outer tube. A heating unit is for heating the outer surface of the emitter tube so that heat energy is transferred by conduction from the outer surface of the emitter tube to the inner surface of the emitter tube, and the inner surface of the emitter tube emits infrared radiant energy into the cavity of the emitter tube so that a majority of the energy that is transferred to the food within the emitter tube is in the form of infrared radiant energy.
