Abstract
Combined microwave-convective drying of 2.4mm-thick radiata pine veneer grown in New Zealand was conducted to investigate drying characteristics. The veneers could be dried from 160% to 0% moisture content in 7.5 min by microwave drying combined with hot-air of 100℃. This drying rate is about three times higher than that of conventional convective drying with only hot air of 100℃. However there remained charred spots when too high microwave power was applied. Therefore investigations of the microwave-drying characteristics of veneer of various sizes and species are needed to determine the optimal drying conditions.
