本研究主要是分析圓柱形旋轉式芝麻焙炒爐的暫態行為，利用時域之有限差分法(Finite difference time domain method)為分析基礎，並使用自行開發的SimLAB 2000模擬程式，探討不同之旋轉爐的變數作用之下，對於芝麻在爐內溫度分布的影響程度，進而找出適合的變數值組合。本研究選出4個焙炒爐的重要變數，分別為爐體轉數、輸入功率、爐長、芝麻填充率，將各個變數選出數個數值代入，觀察芝麻溫度隨軸向位置變化的趨勢，最後配合灰色系統理論(Greysystem theory)的灰關聯分析(Grey relational analysis)，找出各個變數對芝麻溫度影響的程度大小。由分析結果顯示，影響芝麻溫度最大的變數為輸入的功率，影響最小的為芝麻填充率，而爐體長度的影響程度會比爐體轉數大。 The purpose of this thesis is to study the transient thermal behaviorof rotary kiln. Base on the finite difference time domain method, weuse the SimLAB 2000 simulator developed by ourself to study theinfluence of control parameters on the temperature field of sesame inthe kiln. We choose four important parameters: rotary speed, inputpower, kiln length, the fill rate of sesame. The temperaturedistribution is calculated by several selected values of parameters.At last, we use relational analysis of grey system theory to find theinfluential intensity of individual parameter to sesame temperaturefield. From the simulation results, the most important parameter isinput power, the less effect is the sesame fill rate, and theinfluence of kiln length is larger than rotary speed.
