摘要：

Drying schedules for timber have been decided depending on research effort and experience of the dryer's operators. When they encounter drying conditions that are new and/or outside of prior experience, they should find the optimal method to dry timber sufficiently. We think that we can help them to find the optimal schedule by setting up a drying time calculation method based on heat and mass transfer theories. In this study, we focused on high drying temperature above the boiling point, we divided the high temperature drying process into 4 phases, and applied different models for each phase. Approximate data of thermo physical properties for those calculations was obtained from valuable references of the past.
