Sugi ( Cryptomeria japonica D. Don) boxed heart timbers from Miyazaki prefecture were kiln-dried at low humidity under two high-temperature conditions. The distribution of moisture content, changes in moisture content and the generation of internal checks were examined. Our findings are summarized as follows :1) In the examination with an intermediate period of steaming, a large difference in moisture content was observed depending on green timber weight. Each layer of timbers of 34 to 36 kg had a moisture content of about 6%, and layers of timber of 37 to 39 kg had a final moisture content ranging from about 6 to 40%.2) In the examination with a surface-drying stage at a dry-bulb temperature of 75°C and a wet-bulb temperature of 68°C, variation of moisture content in the cross section were almost equalized during the steaming process that followed this stage.3) The amount of moisture content reduction per hour during drying at a dry-bulb temperature of 120°C was about equal at 1.2 to 1.6% for both drying methods.4) Internal checks seemed to be generated near moisture content of 30 to 40%. |
