FIELD: wood-working industry. SUBSTANCE: wood is first heated in chamber at atmospheric pressure, then it is subjected to evacuation at simultaneous supply of atmospheric air. Then equilibrium state is set which is maintained till preset magnitude of residual moisture content of wood is attained, after which evacuation of chamber and supply of air are discontinued. Wood is heated till relative humidity of medium in chamber reaches saturation state. Heat treatment is effected in this medium. EFFECT: enhanced efficiency. 3 cl
