(° C) steam is supplied, and the wood (1) is heated in this high-temperature steam atmosphere. When the wood (1) is heated in this state for a predetermined temperature and time, the composition components of the wood (1), such as cellulose, hemicellulose, and lignin, are altered by steam oxidation and thermal decomposition, and the whole is colored brown. To do. At this time, since the wood (1) absorbs high temperature steam to the inside due to the steam pressure, the internal temperature rapidly rises and the constituent components cellulose, hemicellulose, and lignin are rapidly denatured due to oxidation or thermal decomposition. The whole is uniformly colored brown. Moreover, it is possible to freely control the dark brown concentration by adjusting the steam temperature and the heating time. For example,
When the oak wood was heated in a steam atmosphere at about 170 ° C. for about 1 hour, it was confirmed that the oak wood was colored brownish brown having the texture of the high-quality mahogany wood.

By treating the inside of the high temperature and high pressure container (2) with high temperature steam, the inside of the wood (1) can be uniformly colored brown in a short time in a single step without using paint or dye. it can. Therefore, it is possible to greatly reduce the coating time, and since the inside is uniformly colored, even if it is scratched, it is inconspicuous and it is not necessary to modify the coating. Moreover, the wood (1) is colored by the high temperature steam inside the high temperature and high pressure container (2), and at the same time, the piston rod (8a) is further extended by the compression cylinder (8) of the wood compressing device (5) to make the wood (1). ), The strength, surface hardness and growth density (annual ring width) of the wood (1) can be freely controlled. That is, wood (1)
When the wood is treated with high-temperature steam inside the high-temperature high-pressure container (2), the wood (1) is evenly colored brown to the inside and at the same time is softened by heating, so that the compression cylinder (5) of the wood compression device (5) By further pressing the wood (1) via the compression member (6) by 8), the wood (1) can be easily compressed. Then, the wood (1) is kept in a compressed state in a high temperature steam atmosphere for a predetermined temperature and for a predetermined time, so that the wood (1) undergoes a chemical change due to the high temperature steam and the deformation due to compression is fixed. When the wood (1) is compressed in this way, the strength, surface hardness and growth density (annual ring width) change, and the strength, surface hardness and growth density (annual ring width) are freely controlled by adjusting the compression ratio. be able to.
