摘要

物料在螺旋裝置進行輸送及加工作業時須考慮其分佈情況及滯留時間，以便決定適切的加工操作條件。本研究之目的係採用不同物料於兩段式螺旋輸送器中進行滯留時間分佈試驗，以探討該輸送器在不同螺旋輸送轉速下對於處理花生仁、毛豆莢及草菇等性狀互異之農産品的輸送效果。實驗結果顯示當螺旋轉速提高時有助於穩定出料曲線的提早到達，同時物料之滯留時間分佈曲線也會隨著輸料螺旋轉速的提高而呈現提前出現及分佈變域集中的現象，至於本兩段式螺旋輸送器之攪拌混合效果則不受輸送物料種類或輸送速率之影響而有顯著差異。

During the screw conveying process, the distribution and resident time of materials are very important factors for optimum operation conditions. In this research, peanut nut, young soybean and chinese mushroom with different screw speed of the two-stage transportation hae been tested to analyze the residence time distributions and the extent of axial mixings. The results showed that the stability of outlet curve was advanced by increasing the transport speed. Therefore, the resident time decreased and the spread of residence time distribution concentrated. The mixing and dispersion of this machine was not significantly effected by different materials and transport speeds.
