WOOD SMOKING-SEASONING METHOD comprising a furnace is set to the floor section where wastes such as wood chips, scrapped wood, or wood pieces are put, flammable wastes such as planer chips, plane chips, bark, branches and leaves, or waste paper are arranged as an ignition material so as to cover the upper and lower sides of the wastes, and several resistant steel lids are lain one upon another on the upper side of the furnace so that heat and smoke can pass through the gap between the lids, and therefore the ignition material is ignited, fire expands on the whole surface and inside combustion material is burned keeping the central portion of green-wood stacked on the upper side in a range of 75 to 80 °C and thereby, incomplete combustion is performed and is smoking-seasoned at a low temperature by supplying smoke and hot air to the wood and the stacked wood is seasoned at a low temperature for three days in summer or five days in winter by uniformly circulating smoke and hot air through the wood by convection blowers arranged at various positions in the indoor temperature adjusting damper and the room, and then the wood is left as it is until the difference between the core temperature of the wood and the outside air temperature comes to 5 °C or less and thereafter, the shutter in the room is opened to bring out the wood. According to the seasoning method of the present invention, low-temperature smoking-seasoning is realized, the fuel cost is reduced by using wastes, and a product free from warp or crack is obtained and it is possible to decrease the energy cost by using wastes and manufacture the wood having a small occurrence rate of warps or cracks, mildewproof property, insectproof effect, and high rotproof effect.

L'invention porte sur un procédé de fumage et de séchage de bois d'oeuvre selon lequel du bois résiduel (7) est entassé dans l'enceinte réfractaire d'un four (1) afin d'y être soumis à une combustion partielle par l'intermédiaire d'un conditionnement de l'air. Fumée et chaleur sont amenées par convection entre des pièces de bois (9) empilées et séparées par des lattes d'espacement afin de les fumer et de les sécher à basse température. Ce procédé, qui réduit au minimum le gauchissement et la fissuration est simple et abaisse les coûts car il exige moins de combustible.
