Investigation of High Temperature Drying of Sub-alpine Fir Dimension Lumber
Introduction Kiln productivity is reduced and energy consumption is increased because of the longer kiln residence times required to dry sub-alpine fir (Abies lasiocarpa (Hook) Nutt.) lumber. The objective of this research is to evaluate the impact of high temperature drying (HTD) schedules on drying rates, lumber quality and strength properties for sub-alpine fir dimension lumber. Modeling HTD of sub-alpine fir is an important step towards the design of drying schedules. It will enable kiln operators to examine different drying scenarios and evaluate their potential impact on drying results. Since the moisture transfer mechanisms above the boiling point differ from those that occur during conventional drying (temperatures <100℃), it is necessary to determine some physical properties (diffusion coefficients) that directly influence mass transfer during drying at high temperatures (above 100℃).
