Abstract

The drying times of full-length (8-ft (2.44-m)) sugar maple sapwood boards were compared to those of matched, short [11.5-in. (292-mm)] boards at eight temperature, relative humidity, and air velocity combinations. The results showed little practical difference in the drying times of the boards. We conclude that studies on drying time can be made more efficient by reducing the amount of material and the size of the drying equipment.
