Abstract
A process for drying a liquid layer which has been applied to a carrier material moving through a drying zone and which contains vaporizable solvent components and non-vaporizable components, wherein a drying gas flows in the longitudinal direction of the carrier material parallel to the liquid layer and is accelerated in the drying zone in the direction of flow, is disclosed. Also disclosed is a device for accomplishing the drying process, comprising a drying channel through which the carrier material bearing the liquid layer runs in the longitudinal direction, and a gas-permeable channel-covering surface, through which the gas stream flows into the drying channel.
