WWW Hardwood Drying Schedules

WARNING: There may be bugs in the programs that are used below, or in the data files that they read. If you detect any errors, please contact Steve Verrill at or 608-231-9375. Thank you.

We provide two kinds of drying schedules --- we list the accepted schedules for certain common species, and we estimate appropriate schedules for less common (primarily tropical) species.

The links for the common species are given below, and here is the link to the schedule estimation program.

If you already know the schedule code (for example, T6-D2), then you can go directly to the code to schedule program.

Known schedules

The source of these schedules is the Dry Kiln Operator's Manual, USDA, 1991.
