Module 1 – Introduction to Wood Drying

Workshop Duration: 5 days

What you will learn:

This workshop introduces the terms, concepts and processes involved in drying wood. The course begins by detailing wood anatomy and moisture movement. Students will become familiar with kiln design considerations, drying schedules and kiln loading considerations. Other topics include drying with air, drying degrade, lumber storage and handling, control systems and power plants. These topics are expanded upon in later modules of the program.

Benefits of Attending:

  • Improved drying uniformity
  • Reduced drying times
  • Potential of reduced energy rates
  • Understand the basic design criteria before the purchase of
  • new kilns

 Who should attend:

  • Kiln managers
  • Supervisory & QC staff
  • Maintenance personnel
  • Kiln operators

Module 1 Cost: $995  Kiln Drying Certificate cost (lump-sum fee) $3982

Workshop Schedule:

Wood Anatomy
Strength and mechanical properties, variations in wood structure, moisture content

Drying with Air

Schedules & Availability

CAWP endeavours to make kiln drying course modules available as often as possible and in as many locations as is feasible. As scheduling is decided on an on-demand basis, we encourage potential participants to let us know that a course is desired in their area.  Kiln drying courses may also be delivered in-plant at your company location, or customized to meet specific learning goals.
