に生産性が悪く、実用性に乏しかった。As in the above-mentioned conventional method, after compression molding, wood is placed in a high-temperature and high-pressure steam atmosphere of 5 to 25 kgf / cm 2 to fix deformation by compression molding. If the compression molding form is released while the wood is still hot, the deformation will recover, so the compression molding form cannot be released until the wood cools to room temperature (about 50 ° C). Therefore, in the above-mentioned conventional method, after steam treatment,
To cool wood by natural cooling in a high-temperature high-pressure vessel,
It takes time (several hours) for the wood to be cooled to room temperature and removed from the compression mold. Especially if the wood is large,
For example, if the thickness is about 100 mm × width 200 mm × length 2000 mm, some deformation may recover or burst due to insufficient cooling at the moment when the compression molding formwork is released, even after cooling for several hours. It may take about half a day to completely fix the deformation. For this reason, the productivity was extremely poor and the utility was poor.
