Abstract

Drying stacked cut wood in a drying chamber is accomplished by conducting air between the layers of cut wood. Before and/or during the drying, the air velocity profile in the plane of admission into the stack is adjusted to a modifiable theoretical value. The drying apparatus has at least two measuring sensors for the wood moisture level and/or the flow velocity of the air. The sensors are arranged at some distance from each other in the area of the stack. A flow control system is adjustable dependent upon the measured values obtained by the measuring sensors.
