Abstract: Methods for producing a mono- or multilayer composite are provided in which one or several layers are applied onto a carrier material by coating, the coated mono- or multilayer composite is dried and rolled up, and the installation is subsequently cleaned. The air circuit in the drying oven is entirely set to fresh air supply, and the drying oven is configured to be cleaned in a controlled manner. All components of the drying oven that come into contact with the product do not have to be removed during cleaning, but can be cleaned-in-place using technology integrated into the drying oven. The drying oven Outer housing is designed so that it can be lifted upwardly. All assembly parts in the drying oven interior are designed to eliminate disassembling for cleaning purposes. Transport rollers within the drying oven are designed as hollow shafts and provided with spraying nozzles.

Abstract: A device and a process for drying thin layers or films which are manufactured by applying a coating mass, which is produced on an aqueous basis, to a support, the said layer or film being transported through a drying device having at least one drying zone, is characterized in that in at least one drying zone, designated as moisture-compensation zone, air is supplied which has a moisture content corresponding to the constant moisture content of the film to be prepared or the layer to be prepared.
