The invention relates to a method for drying preferably plate-shaped products containing water in a multistage continuous dryer as well as such a dryer for carrying out said method. The invention is characterized in that humid air accumulated below the housing (2) in a dryer of said type is sucked off and is conveyed into the suction zone (12) of the axial fans (9) located in the lower stages, whereupon humid air is admixed in a differentiated manner to an amount of drying air and is delivered to the nozzle boxes (5) of the dryer.
