  • Method of drying lumber
    Patent number: 4182048
    Abstract: Lumber within a kiln is subjected to a multi-step process including initial dehumidification drying to a moisture content of approximately 12 to 20 percent followed by drying at a substantially higher temperature without dehumidification. The higher temperature drying step is continued until a moisture content of approximately 6 percent is reached, after which high humidity conditions are preferably introduced into the kiln for equalization and/or conditioning of the lumber.
