Abstract
Logs with average diameters of 20~30 cm were dried with microwave to investigate microwave drying characteristic of log and determine the optimal drying conditions. Microwave dryer with output of 20 kW was controlled with respect to the temperature of log during drying. Japanese red pine logs with average diameter of 281.9 mm were dried safely by microwave to below moisture content of 20% within 48 hours. Chinese toon logs showed serious surface checks during microwave drying. Higher drying rates were found with higher initial moisture content.
