The present disclosure provides a method of drying and dyeing wood, the method comprising feeding a green wood having a varying moisture content into an oven and drying the green wood in the oven. The residence time of the biomass in the oven and the temperature of the oven are selected according to a time and temperature profile based on the pre-drying moisture content of the biomass to produce dry surface wood having a moisture content of about 15% or less at the dry surface. The method further includes conveying the dried surface wood to a dyeing chamber and directly dyeing all sides of the dried surface wood after the drying. A system for carrying out the method and a dyed wood product produced according to the method are also contemplated.

The invention discloses a wood fiber green dissociation method based on peroxide. The dissociation method comprises the following steps that a peroxide and a wood fiber raw material are stirred in a solvent, a dissociation product is obtained, and the peroxide is selected from sodium percarbonate. According to the method, partial lignin in an intercellular layer in a wood fiber cell wall of sodium percarbonate is used for transverse permeation and depolymerization, mechanical stirring is combined for longitudinal dissociation of the wood fiber cell wall, and a dissociation product with high lignin content and high crystallinity is prepared under the condition of low power consumption.

The present invention relates to a process for gluing native green wood with a high moisture content (above 20%) for use as building construction material, and to the use thereof on native species, such as roble beech, coigue, lenga beech and rauli beech.
