How to Dry Lumber for Quality and Profit

Kiln operators, supervisors, and others associated with industrial lumber drying have benefited from How to Dry Lumber for Quality and Profit since 1949. In this, the 76^th annual offering, there are in-person and online courses for kiln personnel and non-kiln personnel.

Why lumber drying is important

Reducing downfall from #2&Better to #3 by 1% can add $250,000 annually to the bottom line of a large sawmill. Further, drying consumes 70% of the energy used to convert a tree to lumber and represents 10-15% of the cost. These courses emphasize improving grade while reducing operating costs and maintaining or increasing production.
