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