Patent ID: 7897188

Claim:
A method for baking an edible product comprising the steps of: conveying the edible product along a conveyor track using a motor; controlling the intensity of an electric infrared radiator disposed adjacent the conveyor track during a first heating step so that, per unit of time, more radiation energy is supplied to the surface of the product than can be transmitted to the interior of the product, wherein the infrared radiator comprises a spiral filament disposed in a gastight, infrared radiation-transmitting casing; controlling the intensity of the infrared radiator during a second heating step so that, per unit of time, at the most as much radiation energy is supplied to the surface of the product as can be transmitted to the interior of the product; monitoring breakage of the infrared radiator casing using a transducer, the transducer measuring the electric power taken up by the infrared radiator and transmitting a signal to a controller upon a decrease of the electric power; and automatically stopping the conveying of the edible product along the conveyor track with the controller upon monitoring a breakage of the casing of the infrared radiator.
