Abstract: A method for heat-treating wood, including at least one step of maintaining the wood to be treated at a predetermined temperature in a treatment chamber in order to destroy at least partially the hemicellulose of the wood. The method comprises monitoring the current amount of at least one of the gases given off during hemicellulose decomposition throughout said step, and stopping the treatment step once said amount begins to reach a substantially constant value.

Abstract: The invention relates to a process for separating the surface layer from the core of a piece of wood. During said process, the surface of the piece of wood receives prior mechanical damage, e.g. it is roughened, and subsequently the resultant piece of wood is immersed in water or a water solution until the level of dampness in the surface layer of the wood is at least 30 %. The resultant piece of wood is subsequently steamed at a temperature of from 120 to 160 DEG Celsius, and the surface layer to be removed is consequently superficially etched to such an extent that it can be detached from the piece of wood in a subsequent stage.

Abstract: In order to remove toxic substances from timber for disposal, the timber is ground and a suspension of water, a water-soluble organic solvent and the ground timber is centrifuged in a centrifuge (2). The mixture or water and solvent is extracted from the centrifuge (2) and, after the toxic substances in the mixture have been separated and the organic solvent has been distilled off from the water, the water is reintroduced into the circuit of the centrifuge (2) in order to form a fresh suspension of water, organic solvent and the timber (12) separated in the centrifuge (2). This process is repeated until the timber (12) has been freed from toxic substances.

Abstract: For accentuating the surface play of pinewood, especially pinewood furniture, the wood is subjected to an acid/lye treatment, which additionally affects the colour shade of the fresh wood. Instead of aiming at a light colour shade corresponding to undressed wood, the natural colour shade of which is almost impossible to preserve or reproduce, the invention aims at a darker shading, which is achievable as an exactly true to nature patination of the wood, whereby a real natural colour shade is obtainable, though referring to aged undressed wood. The result is obtained mainly by using a relatively concentrated lye liquid.

Abstract: The invention relates to a method for stocking and preserving green round wood and sawn timber, which is stored in an airtight and lighttight sealing cover. The oxygen inside the cover is decomposed by the respiratory process of mushrooms, bacteria and wood cells that are still alive, thereby forming CO2 and H2O. Fermentation processes also lead to the decomposition of hemicelluloses and saccharides which are converted to organic acids and CO2. The oxygen content in the cover is less than 0.1 vol. % after an adjustment time of 3 to 10 days of total stocking, while said CO2 content rises to more than 21 to 40 vol. % . This method enables green round wood and sawn timber to be stocked over long periods without wastage or environmental damage.

Abstract: The invention concerns an apparatus for the heat treatment of lignocellulosic material, and comprises a chamberfor the treatment of the material, at least one combustion chamber (30) with at least one burner (31) functioning in a reducing atmosphere, stirring mechanisms (26, 26') to ensure the circulation of gases in the treatment chamber so that a part of the gases originating from the chamber circulate across the combustion chamber (30). The invention further relates to a corresponding treatment process comprising the following steps: preheating and drying of the material at a temperature akin to that of saturated liquid; heating of the material in a reducing atmosphere; cooling of the material by the injection of water vapor. The first two steps can be automatically controlled by regulating the burner or burners so that the difference between the temperature outside and that within the material remains substantially constant.

Abstract: A method of drying wood, which can dry wood in a short period of time without the generation of crack, and a method of subjecting wood to impregnative treatment, which can have an impregnant permeate deep into wood at low cost. The method of drying wood comprises the steps of receiving wood in a closed type vessel to heat wood, decompressing an interior of the closed type vessel and restoring to the atmospheric pressure the interior of the closed type vessel after the decompressing step. Also, the method of subjecting wood to impregnative treatment comprises the steps of heating wood, placing the heated wood under decompression, immersing the heated wood in an impregnant under decompression, returning an ambient pressure around the wood, which is immersed in the impregnant under decompression, to the atmospheric pressure to immerse the wood in the impregnant under the atmospheric pressure.
