Abstract: A toaster uses radiant heat at infrared wavelengths optimized for producing rapid and uniform toasting of a food product. The infrared wavelengths of the radiated heat are selected for optimum speed and quality (browning and moisture content) of the food product. The selected infrared wavelengths of the radiated heat may also effectively defrost a food product. Defrosting of the food product by the infrared radiated heat adds very little time in obtaining a desired toast color to the food product. A plurality of infrared wavelengths of radiated heat may also be used, wherein the plurality of infrared wavelengths are selected for optimal heat penetration and surface browning of the food product. Shorter wavelengths for browning and slightly longer wavelengths to penetrate the food product for evaporating the moisture therein to allow surface browning by the shorter wavelengths.
