Abstract
A food holding oven holds pre-cooked food at a selected temperature by heating the food in a food-holding tray using infrared energy obtained from a multi-layer planar infrared energy source above the food. The infrared emitted from the planar IR source is produced by electrically heated windings in either a boustrophedonic or crenellated pattern, the loops and crenellations of which are more closely spaced near the edge of the heater than they are away from edges of the heater. The IR from the heater is directed toward the tray such that there is more IR directed at the tray edges than is directed toward the tray interior regions.
