The purpose of this study was to compare the drying curves of
2-inch thick Douglas-fir heartwood boards as predicted by a
computer simulation by C. A. Hart (1983) with those actually
observed in experimental kiln runs. The moisture gradients within
test boards were also simulated by the computer program and...
Past research and industrial sources have implied that preheating Douglas-fir Pseudotsuga menziesii (Mirb.) Franco prior to peeling veneer was economically feasible. To test this, the effect of treatment temperature on veneer yield and thickness variation for three diameter classes of low grade Douglas-fir logs was studied and related to the...
Because of the increasing need for the plywood industry to improve the performance and adaptability of its production facilities to meet demand, the need for a process-related decision-aiding method has been growing. The objective of this study was to develop a computer simulation for a plywood plant starting at the...
New technology allows the production of thinner kiln sticks
manufactured of phenolic resin impregnated paper which are both
structurally and economically realistic. This project tested the effects
of kiln stick thicknesses on dry kiln air circulation and on
lumber drying degrade.
Three variables, stick thickness (3/4, 9/16, 7/16 and 1/4...
