A drying apparatus has a housing, a conveyor for displacing a flat workpiece horizontally in a travel direction through the housing on a level, and a horizontal array of horizontally elongated upper nozzle boxes lying generally in a plane above the level. Each box is formed with a plurality of downwardly directed nozzle holes and heated air is fed to the boxes so it is projected from the holes against the workpiece for drying same. Respective upper shield plates each formed with a plurality of apertures are slidable on the respective boxes between a position with the apertures aligned with at least some of the respective holes and a position with the apertures out of line with the respective holes. At least one pivotal rod extending along a rod axis in the direction has radially projecting arms each engaged with a respective one of the respective shield plates. The rod can be pivoted about the rod axis to shift all the shield plates between their positions.

Continuous dryer for flat workpieces

A drier for broad articles such as plasterboard has a conveyor in entraining the plasterboard along a drying path in a transport plane and the nozzle boxes for contacting the plasterboard with the drying air have their orifice surfaces inclined to the plasterboard to achieve uniformity of drying in terms of residual moisture content.
