摘要: 
A colorimetric method was used to study the residence time distribution
(RTD) in anAPV Baker MPF 50/25 twin-screw extruder using rice flour as the feed
material. The redness color value and the concentration approaches were used to
determine the R

比色計法被用來研究米穀粉在雙軸擠壓機(APV Baker MPF50/25)內滯留
時間之分佈情形。本研究使用兩種方式來計算滯留時間之分佈情形,其一是直接
以比色計測得的紅色值來計算,其二是將紅色值轉換成濃度來計算。由結果顯
示,此兩種不同方式研究物料在擠壓機內之滯留時間分佈,有顯著之差異。利用
比色計測得的紅色值直接計算物料在擠壓機內文平均滯留時間,會比實際值大
(亦即會超估),因之,利用濃度來計算擠壓機內物科之滯留時間是唯一正確之方
式。
