Effect of a Radio-frequency/Vacuum plus Press Drying Process of Some Hardwood Veneers for Decoration on Checking and End Waving

During a radio-frequency/vacuum plus press drying process of some hardwood veneer for decoration we investigated the effect of a gain and thickness of a veneer sheet on drying rates, variations of final moisture content within a bundle of veneer sheets, and formation of checking, end waving, and burning mark. About thirty three hundreds sheet of veneer could be dried in sixty five hours from green to in-use moisture content, and a final moisture content was significantly effected by initial moisture content of veneer. Three were nearly variations in a final moisture content among the veneer sheets in the same bundle. A checking was never found in a edge-sliced veneer, and was very slight in a flat-sliced veneer of ash and red oak. There were no end waving and no burning mark in all veneer sheets.
