High temperature drying of southern hardwoods (E. V. Smith)


THE IDEA Of drying lumber at temperatures above the boiling point of water has intrigued lumbermen for years. Since World War II there has been a renewed interest in this subject, stimu-lated largely by successful applications in Europe and encourag-ing research results with Canadian woods.
It is well known that different species and different thicknesses of lumber differ considerably in drying rate and in tolerance to accelerated drying schedules. In view of these facts, the present
exploratory study was designed to learn if useful lumber thick-nesses of representative southern hardwoods could be dried at temperatures above the boiling point of water without excessive
degrade.

The effectiveness of high temperature drying in reduc-ing the hygroscopicity of wood was also to be evaluated.
