PCT No. PCT/FI87/00140 Sec. 371 Date May 25, 1988 Sec. 102(e) Date May 25, 1988 PCT Filed Oct. 26, 1987 PCT Pub. No. WO88/03193 PCT Pub. Date May 5, 1988.The invention concerns a procedure for drying a moving web material (E), wherein on the material (E) to be dried is directed infrared radiation, and wherein the moving web material is transported through the radiation zone of an infrared radiator, the web material to be dried absorbing radiation. On the moving web material to be dried is directed the radiation produced by at least one first infrared radiator (T1) and the radiation produced by at least one second infrared radiator (T2), the radiators being disposed close to each other, the maximum intensity wavelength ( lambda maximum) (T1) of the radiation from the first infrared radiator (T1) being smaller than the maximum intensity wavelength ( lambda maximum) (T2) of the radiation from the second radiator (T2), whereby in the drying process the spectrum of the total radiation is maximally advantageous in relation to the absorption spectrum of the material to be dried. The invention also concerns an IR dryer.
