Patent ID: 8291610

Claim:
An operating method of an apparatus for drying a painting product applied onto an object; the apparatus comprising a radiating assembly comprising at least one catalytic panel, which is fed with hydrocarbon gas for generating infrared radiations according to a first emission spectrum in the short-wave infrared band upon a catalytic reaction between the hydrocarbon gas and the oxygen present in the air and is adapted to emit the infrared radiations towards said object for drying the painting product; the method being characterized in that it comprises the steps of: blowing, by means of supplying means, a mixture of air and oxygen onto the catalytic panel for influencing said catalytic reactions so as to generate a second infrared radiation emission spectrum broader than that first emission spectrum and distributed in the entire short-wave infrared band; storing an optimal drying temperature univocally associated to the painting product in an electronic memory; measuring the temperature of said painting product by means of a temperature sensor associated to said catalytic panel; and adjusting, by means of a first solenoid valve, the feeding of said mixture of air and oxygen to said catalytic panel according to the deviation between the measured temperature of said painting product and said optimal drying temperature.
