Abstract

The objective of this study was to evaluate the moisture profile and drying period of air drying the red pine and Japanese larch timbers with the cross section of 14.0 cm × 14.0 cm and 16.5 cm × 16.5 cm by measuring the electric resistance of the wood. The drying curves determined by measuring electric resistance and by oven-dried method were nearly identical at last drying stage, and had almost same moisture profiles and same drying period after the end of air drying. Therefore, the drying curve determined by measuring electric resistance can be used to predict the drying period and moisture profile of air drying the red pine and Japanese larch timbers with large cross sections.
