Abstract: A process for drying or curing green wood including the heating of green wood in a heating enclosure to a predetermined temperature over about 120 F while maintaining the moisture content of the wood close to the original moisture content of the felled wood, and then immediately cooling the heated wood with a cooling fluid at a temperature and humidity substantially less than the temperature and relative humidity of the heating enclosure for a time period sufficient for the wood to reach substantially the reduced temperature of the cooling fluid for normally removing at least about 5% of moisture from the green wood. The green wood is conditioned by the cooling step for subsequent drying steps in which moisture removal rates are substantially higher than moisture removal rates under prior conventional drying steps. The green wood process as set forth is effective to minimize staining of the wood.

Abstract: A green wood treating process for treating wood in a green stage prior to curing for preventing or minimizing staining of the wood. The process includes the heating of green wood in a heating enclosure (30, 40) within a maximum time period after felling or cutting of the tree forming the wood while maintaining the moisture content in the wood after the tree is felled without any appreciable loss of moisture. After the logs are cut into lumber, the lumber is placed in bundles in the heating enclosure for heating preferably by steam within a predetermined time period. The wood is heated in the enclosure to a temperature over 120 F. for a predetermined time period generally over about two hours and sufficient to provide a generally uniform heating of the lumber. After heating of the wood to a predetermined temperature, a cooling fluid having a temperature substantially less than the temperature of the heating enclosure is applied to the heated wood for a predetermined time period.
