摘要： Object for the invention is a method for treatment and drying of wood, in which at the first phase wood is warmed up over to the temperature close of the boiling point of water, and wood is compressed with a variable pressure between moisture permeable pressing elements, the temperature of the wood is increased so quickly, that the moisture existing in the wood does not have time to evaporate essentially before the temperature of the wood has increased around the boiling point of water. According to the invention when the surface layers of the timber have reached the temperature close the boiling point of the water the pressure is increased, and at the pressing phase the temperature of wood is kept at the temperature range close the boiling point of the water under that higher pressure.
