Abstract

Low-temperature forced-air drying involves drying green lumber in heated buildings with forced-air circulation and partial control of temperature and humidity conditions. The lumber is dried to about 20 percent moisture content at dry-bulb temperatures of 70º to 110ºF and with air velocities of 300 to 600 feet per minute. Equipment, methods, and procedures for commercial application of low-temperature drying in the Appalachian hardwood region are described, including dryer design and construction, drying schedules and drying times for commercially important Appalachian species, and detailed instructions for operating the dryer and using the schedules.
