A continuous oven for heating a food product having an outer surface and
an interior includes an enclosure with a first heating zone and a second
heating zone. A conveyor is configured to convey the product from the
first heating zone to the second heating zone. At least one
surface-browning infrared emitter is adjacent the first heating zone of
the conveyor and is configured to provide a first electromagnetic
radiation profile to the product in the first heating zone that is
adapted to evaporate surface moisture to produce a crust matrix on the
outer surface of the product. At least one interior-heating infrared
emitter is adjacent the second heating zone of the conveyor and is
configured to provide a second electromagnetic radiation profile to the
product in the second heating zone that is different from the first
electromagnetic radiation profile. The second electromagnetic radiation
profile is adapted to heat the interior of the product. This
configuration can produce food products that have characteristics
approximating immersion-fried food products.
