Abstract (en)

A process capable of improving dimensional stability and surface properties of a lignocellulosic material is disclosed which comprises holding a lignocellulosic material (W) between hot platens (1a,1b) in a sealed condition, and heating the lignocellulosic material to vaporize moisture contained in the lignocellulosic material per se; thereby effecting high-pressure steam (V) treatment of the lignocellulosic material. In the treatment, the lignocellulosic material may be maintained in a compressed condition, or an external high-pressure steam (V) may be supplied from the surfaces of the hot platens toward the lignocellulosic material. <IMAGE>
