Press-Drying Green, Flatsliced Walnut Veneer to Reduce Buckling and End Waviness

Flatsliced walnut face veneer was dried under 10 different conditions and then compared primarily for residual buckle. The most effective method tested was press-drying flatsliced walnut veneer 0.030 inch thick at 230? F and a pressure of 50 pounds per square inch to a moisture content of 6 to 9 percent. Buckle was reduced to about one-third that found in matched sheets dried at 230? F in the roller-conveyor dryer to a moisture content of 5 to 7 percent. Press-drying was also faster by about 30 percent. Press dried veneer had a faint screen pattern and was more brown in color than conventionally dried veneer.
