Abstract

Methods for drying a substrate. The methods include the following steps: (a) emitting infrared radiation towards a substrate moving through a process space using an emitter unit comprising at least one infrared emitter, (b) generating at least two process gas streams of a process gas directed towards the substrate, (c) drying the substrate by the action of infrared radiation and process gas on the substrate, and (d) extracting moisture-laden process gas from the process space via an extraction duct, forming an exhaust air stream leading away from the substrate. To specify a drying method which is reproducible and effective and leads to an improved result, in particular in terms of homogeneity and speed of drying of the substrate, the at least two process gas streams are guided to the infrared emitter before they act on the substrate, and an exhaust air stream is spatially assigned to each process gas stream.
