摘要


為探討風扇轉速對乾燥速率,乾燥品質與電力消耗之影響,特以3cm厚肯氏南洋杉為試材,就1段(RPM=1200)與2段(RPM=1200~600)轉速進行試驗。結果顯示:2段轉速對乾燥速率與品質無減低之影響;木材含水率降至FSP時,將風扇馬達之轉速減低1/2,可節省電力12%以上。

The objective of this research was to evaluate the effects of fan speed on drying rate, drying quality and electricity consumption during kiln drying of wood. One-speed (RPM=1200) and two-speed (above FSP, RPM=1200; below FSP, RPM=600) fan motors were used for this study. The test material was 3cm×12cm×160cm Cunningham araucaria. The results of this study indicate that: 1. The drying rate and drying quality are not reduced or degraded by using a two-speed fan motor system. 2. Electrical power consumption can be reduced by more than 12% by lowering the fan motor speed from 1200 RPM to 600 RPM as the FSP of the wood is approached.
