Abstract

A method and an apparatus for drying a substance that is being rapidly conveyed in a conveyor apparatus, in particular for drying layers of printing ink on rapidly transported paper, wherein in a drying zone by means of incident electromagnetic radiation a moisture component, in particular a solvent, is separated from the substance to be dried. The separated moisture component is transported away from the drying zone by means of a transport gas current. Efficient and rapid drying of in particular printed newsprint or thermal printing paper is attained at high conveyor velocities.
