Infrared can supply 8000 ~ 2500kJ / (h m2) of the heat to the surface of  materials , useing such heat for drying operations dryer knowns as infrared dryer. It is mainly used for thin materials, coating and drying liquid paint drying and so on. As infrared heat source of infrared light (filament temperature of 1700 ~ 2200 ℃) and the resistance heating body (600 ~ 1200 ℃), often arranged in such tunnel-shaped heat source, so that continuous passage of material to be dried.In order to focus on the material heat the surface, but also has a sounding board.There are a large difference in energy absorption between different colors of materials.

There is a photo of  infrared dryer which is invented and made by Suzhou Oude:
