Abstract
A method for drying lumber in a short time with less use of energy. The method of drying lumber includes: enclosing lumber in a batch container having a pressure release valve; filling fluid into the batch container under pressure; maintaining a temperature and a pressure at or above a critical point of the fluid for a certain period of time; and then opening the pressure release valve of the batch container to reduce the internal pressure to atmospheric pressure.
