Research output: Contribution to journalArticlepeer-review


A new process using pressurized carbon dioxide was investigated in order to minimize the carrying cost of wood. This process was performed using the following steps: (1)Firstly, woods were placed in a pressure vessel, (2) Secondly, the vessel was pressurized with carbon dioxide, (3) Thirdly, the pressurized state was held for a certain period and the pressure was then released suddenly. Experimental results obtained from this study were as follows; The carbon dioxide drying process could easily reduce one half of the moisture content ratio of woods. The higher pressure of carbon dioxide gave the more effective drying of woods.
