Patent ID: 7335858

Claim:
An apparatus for toasting a food product, comprising: a toasting chamber adapted for receiving a food product to be toasted, the toasting chamber having first and second sides; a first infrared heater comprising a first electrically conductive filament inside of a first quartz glass tube, the first infrared heater being located on the first side of the toasting chamber; a second infrared heater comprising a second electrically conductive filament inside of a second quartz glass tube, the second infrared heater being located on the second side of the toasting chamber; a first radiant heat reflector located on the first side of the toasting chamber, wherein the first infrared heater is located between the toasting chamber and the first radiant heat reflector; and a second radiant heat reflector located on the second side of the toasting chamber, wherein the second infrared heater is located between the toasting chamber and the second radiant heat reflector; wherein the first and second quartz glass tubes are chemically etched so as to pass a desired infrared wavelength from the electrically conductive filament, and wherein the first and second infrared heaters emit infrared radiant heat at a wavelength optimized for toasting of the food product.
