Abstract

A method and device for drying sheets is described. The sheets are guided through a drier divided into drying chambers and brought in contact with the drying air by means of impinging jet aeration. The impinging-jet aeration utilizes cross-aerated nozzle boxes and the main drying stage exhaust air is introduced in the pressure chamber of one or more drying chambers in the first half of the final drying stage. Pan of the exhaust air in the recirculated-air operation is used for drying in the drying chamber and part of the exhaust air is introduced into the suction chamber of the respective subsequent drying chamber. The exhaust air collectively passes through the final drying stage in this manner, and the exhaust air from one or more drying chambers in the second half of said stage is extracted at a significantly lower temperature.
