A continuous press dryer for veneer

The purpose of this research was to determine the feasibility of continuous press drying of veneer. An experimental dryer developed at the USDA Forest Service, Forest Products Laboratory (patent applied for) shows promising results. Compared to a laboratory roller dryer with longitudinal air flow, the experimental dryer dried 1/32-inch aspen veneer in 25 percent less time, with 67 percent less transverse shrinkage and volume loss, and the veneer was much flatter and smoother. Compared to a laboratory platen press, the experimental dryer dried veneer with 75 percent less thickness loss and 60 percent less volume loss.
