摘要

米穀粉被應用於研究雙軸擠壓機之加工變數對擠壓產品物理特性之影響。本研究之加工變數為：螺絲元件組合，進料速率及螺軸轉速。擠壓產品之物理特性包括：總體密度、眞密度、比容積以及切斷强度。
研究結果顯示，進料速率是在雙軸擠壓穖的加工變數中，影響擠壓產品之上列物理特性最顯著的因子。螺軸轉速影響擠壓產品之上列物理特性居次，螺絲元件組合影響擠壓產品之物理特性最小。

Rice flour was used to study the effects of process variables on extrudate's physical properties in an APV Baker MPF50/25 twin-screw extruder. The process variables were screw profile, feed rate, and screw speed. The extrudate's physical properties measured in this study were true density, bulk density, apparent specific volume, and breaking strength. The effects of the process variables on the physical properties were investigated.
The feed rate was the most important variable affecting the extrudate's physical properties. Screw speed was the second important factor affecting the physical properties of the extrudate. The screw profile affected the extrudate's physical properties least.
