中文摘要 | 本研究以全脂大豆粉為原料,利用3×3×3複因子實驗設計,以探討改變單軸擠壓機之操作參數(套筒溫度、螺軸轉速及進料速率),對原料在擠壓機內之滯留時間分佈及對擠壓產品物理性質之影響。 實驗結果顯示: 1.套筒溫度、螺軸轉速及進料速率對原料在擠壓機內的平均滯留時間均有影響;其中以進料速率之影響最為顯著,進料速率愈低時,物料在擠壓機內的平均滯留時間會愈長。 2.進料速率之改變對軸向擴散及產品總色差值均有顯著影響。當進料速率愈高時,軸向擴散數愈大,而產品總色差值反而愈小。 |
英文摘要 | The full-fat soybean flour was used as the raw material to study the effects of process parameters on extrudates residence time distributions and physical properties by single-screw extruder. The process parameters were barrel temperature, screw speed and feed rate. The experiment was a 3×3×3 factorial design. Results showed that: 1. Barrel temperature, screw speed and feed rate were influential in mean residence time. Mean residence time was significantly affected by the feed rate. Decreasing the feed rate raised the mean residence time. 2. The feed rate had the greatest effect on the vessel dispersion number (D/μL) and total color differences (△E). Increasing the feed rate raised the vessel dispersion number, but decreased the total color differences. |
