Abstract
The present invention relates methods for heat treatment of wood. The invention further relates to wood obtainable by the methods of the invention as well as the use of the method for preparing treated wood. The method comprises the step of pressurising said airtight tank (4) to a predefined pressure (P1) in order to establish a pressurised environment for said wood (6). The method comprises the step of placing said wood (6) in an airtight tank (4) and heating said wood (6) to a predefined temperature (T2, T3). The predefined pressure (P1) is kept so high that the water in the wood (6) cannot evaporate at the predefined temperature (T2, T3).
Claims15
A method for heat treatment of wood comprising the steps of
- placing said wood in an airtight tank,
- pressurising said airtight tank to a predefined pressure to establish a pressurised environment for said wood,
- heating said wood to a predefined temperature by dielectric heating, wherein the predefined pressure during heating prevents water present in the wood from evaporating at the predefined temperature.
