Patent ID: 7853128

Claim:
A method for toasting a food product with infrared radiant heat, said method comprising the steps of: evaporating moisture from and browning surfaces of a food product in a toasting chamber with radiant heat at a first infrared wavelength emitted from infrared heaters located on each side of the food product and radiant heat at a second infrared wavelength reflected from radiant heat reflectors located on each side of the food product wherein: the infrared heaters are located between the radiant heat reflectors and the food product; at least one of the infrared heaters comprises an electrically conductive filament inside of a quartz glass tube; and the quartz glass tube comprises at least one of: a quartz glass tube chemically etched so as to pass at least one of the first infrared wavelength and the second infrared wavelength from the electrically conductive filament; and a quartz glass tube having extruded grooves therein so as to pass at least one of the first infrared wavelength and the second infrared wavelength from the electrically conductive filament.
