Embodiment Construction

[0031] figure 1 An embodiment of the hoods 4 , 5 of the drying device 1 according to the invention is shown. The hood 4 here surrounds the last drying group of the drying plant 1 according to the invention, and the hood 5 surrounds the penultimate drying group of the drying plant 1 according to the invention. The other hoods 4 equipped with higher drying devices have a higher height than the hoods 5 of the first drying group. The hood 4 preferably has hood doors 10 , 11 on the operator's side, which do not extend over the entire height of the hood 4 . A window 8 and a door 9 are provided in the hood doors 10 , 11 . This enables, on the one hand, an external visual inspection from the operator level 2 and, on the other hand, access to the lower region of the drying group for inspection purposes without interfering with the production run. For quick opening of the hood 4 and thus quick ventilation, a movable flap opening 14 is provided above the hood doors 10 , 11 and in the ...
