Hardwood Lumber Drying Short Course

Operating a lumber drying facility, especially one drying hardwood lumber, requires special skills.  A significant amount of lumber can be degraded or damaged during drying when proper techniques are not used.  This course is for beginning operators and supervisors drying hardwood lumber in steam or dehumidification dry kilns and in predryers.  The program will cover practical techniques for the efficient and effective operation of predryers and dry kilns.  The program will include moisture measuring and the use of sample boards; kiln and predryer operational techniques; drying schedules; causes and cures for drying defects, and quality control procedures.
