摘要： A food holding oven, which is used to keep previously-prepared foods hot until they are served, is provided with a food holding tray having a roughened or matte finish. The matte finish keeps the tray's service temperature lower and easier to handle than prior art trays with highly reflective, shiny surfaces. When the matte-finish tray is held under a principally pure infrared heat source for long periods of time, the tray's surface temperature prevents food from being burned and reduces the likelihood of a user being burned.

摘要： A controller for a food holding oven determines one or more time periods during each of which heat is directed at a pre-cooked food item. By controlling the heat intensity and the time over which different amounts of heat are provided to different types of pre-cooked food items, the time during which a particular type of pre-cooked food item can be kept palatable is maximized.

摘要： 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.
