Lumber drying by jet impingement of air on the surface is discussed. The method requires less drying time than conventional drying methods. A description of a prototype jet impingement dryer capable of handling wood four inches thick, twelve inches wide, and 30 inches long at temperatures from 80 to 400/sup 0/F is briefly described. The influence of operating variables on drying times and wood quality was demonstrated in tests run on drying silver maple and yellow poplar. Test results are described comparing the data with conventional drying variables. An attempt to dry black walnut wood with jet-drying was unsuccessful; results of a combined low and high temperature schedule of drying are briefly described. (MCW)
