Process and apparatus for drying work pieces with a surface coating

摘要

At least a part of the walls in the area of the conveyor zone (3') and/or structures of the drying zone (3) is fed with hot air. The walls are located in the area of an output air channel (15) for feed-back of the hot air. The walls form at least one section of the under side (29) of an output air channel (15). The output air channel is located above the conveyor zone of the workpiece conveyor device, and extends in the conveyor direction. At least one side of the output air channel is provided with an input air channel (7,8) for feed of input air. The input air channel has several outlet apertures (27,28) from which the hot air emerges for feed to the walls or the structures.
