Warren, S. | Johnson, G.
This study evaluates the economic benefits of sorting green lumber into moisture content classes before kiln-drying. Laser moisture sensing technology was implemented in the sawmill for sorting purposes. The grade outturn and energy savings resulting from shortened drying times were examined. The final moisture content distribution resulting from moisture sorting did not show overdrying or underdrying. Based on grade outturn, the benefits were as much as $15.94 per thousand board feet (MBF) for 2 by 4 by 16 lumber and $19.66 per MBF for 2 by 6 by 16 lumber; energy savings were $1.88 per thousand board feet.
