Abstract (en)
[origin: EP1950516A2] The invention concerns a method for adapting the requirement for drying air in a wood dryer, whereby wood in the form of a package is placed into a drying chamber that is closed to the surrounding atmosphere and in which is maintained a water-containing atmosphere with a wet temperature, a dry temperature and the psychrometric difference that is associated with this by means of forced drying air that is caused to pass through the wood. In order to optimise the consumption of electricity during the drying process, the air speed of the forced drying air is regulated depending on the current water content of the wood or by a recorded reduction in the release of water from the wood, whereby monitoring of the current water content or the appearance of a reduced release of water takes place by measurements that are carried out during the drying process.
