  • Fig. 11 shows a third constellation of the position of the flap parts 64, 66, which differs from the constellation Fig. 10 differs in that the flap member 64 is in an intermediate position in which it acts as a flow baffle.
  • Fig. 12 shows the flap parts 64, 66 in their closed position, in which they are substantially horizontal are arranged and close the opening 32. In the closed position, the flap parts 64, 66 bear tightly against one another with their free ends. However, they can overlap.
  • the shut-off device 62 serves to increase the energy efficiency of the drying device 2 and at the same time offers manifold possibilities of the flow line.
