    Abstract: 經由實驗與理論分析所獲得的焙炒爐傾斜角度對溫度場的成果,可分成實驗量測與數值分析兩大部份,實驗量測部份,利用線熱源法和熱傳導係數測定器量測出芝麻的熱傳導係數、熱容及熱擴散係數,並應用最小平方差法推導出溫度在20℃-40℃,含水率在2.3%-12%的範圍內,熱傳導係數相對於溫度、含水率的關係式為K=0.0867+0.5897M+0.0023T亦推導出溫度30℃時,熱擴散係數相對於含水率的關係式α=0.091+0.3705M熱容相對於含水率的關係式C=1. 687+0.148M數值分析部份,運用ANSYS有限元素分析套裝軟體來進行分析,探討焙炒爐的傾斜角度,焙炒爐的軸長與芝麻的填充率對焙炒爐溫度場的影響,從分析結果發現,整體溫度場中,爐床外緣(EB)的最高溫度、最低溫度和平均溫度會隨著焙炒爐傾斜角度的增加而遞減。就焙炒爐軸長而言,焙炒爐軸長增加會增加整體溫度場中的最高溫度與平均溫度。若加上傾斜角度時,爐床外緣(EB)的溫度會隨著傾斜角度增加而下降。單以芝麻的充填率來討論,整體溫度場中的最高溫度、最低溫度和平均溫度都會隨著芝麻充填率增加而下降。再加上焙炒爐傾斜角度時,最高溫度、最低溫度和平均溫度下降的幅度會隨傾斜角度的增加而加大。
    The purpose of this thesis is to find out the effect on thetemperature field in a sesame furnace. The experiment result is to usethe line heat source method and the apparatus-thermolink are appliedto measure the sesame thermal conductivity, thermal diffusivity andthermal capacity. The thermal conductivity of sesame withintemperature range from 20℃-40℃ and moisture rate range from 2.3%-12%is K=0. 0867+0.5897M+0.0023T when sesame temperature is 30℃, thethermal diffusivity is α=0.091+0.3705M when sesame temperature is30℃, the thermal capacity is C=1.687+0.148M The numerical analysis isto use the finite element analysis software-ANSYS to study theinfluence of inclined angle, axial length and fill rate on thetemperature field. It is found that when the inclined angle of thefurnace is increase, the maximum temperature, the minimum temperatureand the average temperature in the interface between sesame and airare reduced, respectively. The larger the axial length of the furnacethe higher the maximum temperature and the average temperature, but tojoin the inclined angle effect, the larger the inclined angle of thefurnace the lower the temperature in the interface between sesame andair. The more the fill rate of the furnace the lower the maximumtemperature, the minimum temperature and the average temperature, butto join inclined angle effect, the larger the inclined angle of thefurnace, the maximum temperature, the minimum temperature and theaverage temperature in the interface are reduced apparently.
