Wood-drying way in kiln basis on wood placement preferably on spacers inside the drying kiln, then providing the interior of the steam, heating it up to displace atmospheric air by steam and continue until the superheated steam is obtained, it characterizes according to invention, that after reaching the inside of the dryer temperature in the range of 70-80°C, wood is relaxing without changing of thermal conditions within the drying kiln for 2 to 3 hours. Then the drying phase is carried out at a maximum of 120°C, preferably keeping it in the range of 105-110°C until it reach the desired final moisture content of wood. The wood cools itself spontaneously, and the entire process is carried out in conditions of atmospheric pressure. Preferable is warming up at a rate of 1-1.5°C per hour. |
