<p>The invention relates to a method and an apparatus for drying and/or thermally treating wood, wherein a batch of wood (2) to be processed is placed in a drying chamber (1) that is divided off from its surroundings, and energy is supplied to the chamber to dry the wood. In order to provide rapid drying, a negative pressure is generated in the drying chamber (1), and the energy used in the drying is supplied to the drying chamber (1) in the form of high frequency energy. When the moisture content has almost dropped to the final moisture level, the negative pressure is eliminated from the drying chamber (1), whereupon the final drying and/or thermal treatment are carried out by means of heat.</p> |
