Synopsis

Master the practical science of kiln drying lumber at atmospheric pressure for real-world results.

This guide presents the essential principles that govern heat, humidity, and airflow in drying operations. It translates experimental findings into usable methods for commercial practice, with an emphasis on safe, effective drying.

The book frames drying as an engineering problem: control heat and relative humidity to move moisture out of wood efficiently. It explains why thorough initial heating, gradual humidity changes, and uniform temperature throughout the pile matter, and how large air circulation supports these goals. The discussion also covers how to design and operate kilns, and how to adapt methods to different woods and uses.

Grounded in Forest Service experiments, the text offers practical approaches for applying core principles. It describes methods for regulating humidity with water-spray condensers, maintaining heat with ample air flow, and using temperature to drive drying without compromising wood quality. There is also guidance on when and how to adjust procedures based on observed results.

• Heat wood thoroughly before drying begins to improve moisture transfer.
• Control humidity rather than simply increasing circulation to avoid defects.
• Maintain a large, consistent air flow to keep temperatures even inside the pile.
• Use steam jets or humidity-regulating systems to prevent checking and over-drying.

Ideal for operators of dry kilns, mill managers, and others seeking reliable, empirically grounded methods for drying lumber.
