Lumber Drying Training


How to Dry Lumber for Quality & Profit


Kiln operators, supervisors, and others associated with industrial lumber drying have benefited from How to Dry Lumber for Quality and Profit since 1949 when it was first offered at Oregon State University.  In this, the 75th annual offering, there are separate courses for kiln personnel and non-kiln personnel.


This course is divided into 12 modules each with two to eight lessons. Each lesson has full audio, photographs, and some video that the learner can take at their own pace. There are four discussion assignments (selected from eight topics) for the learner to post an experience or example related to the topic. Overall, the course requires 20 to 30 hours to complete.

The complete course can be taken anytime without webinars. A webinar option will occur from October 9 to December 9, 2023, with webinars at 8 am Pacific on October 18, November 1 ,15, and 29, and December 6.


This course is for personnel who need to interact with the kilns but not operate one. It will benefit personnel who prepare lumber and load kilns as well as maintenance personnel and managers in other departments. Why lumber is dried and how kilns work are covered and the impacts of sorting, stacking, and handling on kiln performance are discussed. Handling of dry lumber is also covered. Examples of the costs of poor practices are included. The narration time is one hour, and the course can be completed in under two hours. It is self-paced and available anytime.
