Abstract:
A device for drying sheets includes:
a conveying device for conveying sheets through the device for drying sheets,
a first drying stage arranged towards an upstream end of the device for drying sheets and comprising at least one drying chamber,
first stage drying air supply means for introducing hot air into said at least one drying chamber of said first drying stage at a drying air inlet;
air discharge means for discharging exhaust air from said at least one drying chamber of said first drying stage,
a second drying stage arranged downstream of the first drying stage and comprising at least one drying chamber;
transfer means for transferring exhaust air discharged from said at least one drying chamber of the first drying stage into said at least one drying chamber of the second drying stage;
humid drying air supply means for introducing said exhaust air into said at least one drying chamber of said second drying stage, said humid drying air supply means comprising at an humid drying air inlet for introducing humid drying air arranged at an upstream position of the second drying stage;
supplemental air supply means for introducing supplemental air into said second drying stage at an supplemental air inlet arranged downstream of said humid drying air inlet.
A method for drying sheets is also disclosed.
