摘要： A drying apparatus for sheets of material. The apparatus includes a drying chamber through which a sheet of material which is to be dried is conveyed, and in which the sheet of material is contacted by flowing drying gas. The apparatus also includes a feed line for supplying drying gas to the apparatus, a heater for heating the drying gas, and a withdrawal line for withdrawing the drying gas from the apparatus. The drying chamber includes cup-shaped and rounded-off wall elements which are easily detachably connected to one another. The wall elements have a smooth inner surface. A jacket is disposed around the drying chamber. An intermediate space is defined between the inner surface of the jacket and the outer surface of the wall elements of the drying chamber. Drying gas is introduced through the feed line into the intermediate space. After this drying gas has been heated in the heater, it flows through the drying chamber. A pressure gradient is maintained between the intermediate space, the drying space, and the atmosphere, with the pressure being lowest in said drying chamber means. The hot drying gas in the drying chamber gives off at least some of its heat to the drying gas in the intermediate space. The used drying gas leaves the drying chamber via the withdrawal line.
