摘要


咖啡豆如果未經過烘焙只是平凡無奇的紅果子,經由烘焙過後才能讓它脫胎換骨,而台灣的咖啡市場已經逐漸成熟,咖啡人口急遽膨脹,人們對咖啡的要求愈來愈高,市場上精品咖啡會依產區、豆種去做不同程度的烘焙,讓豆子產生各種不同有趣的風味,賦予豆子不同的個性,因此如何對不同豆種維持不同深淺程度的均勻烘焙品質,特製化就變得非常重要,而影響咖啡豆烘焙的因素非常多,從豆子本身的挑選到烘焙機的種類,烘焙的火源型式,滾筒的設計及時間的控制,甚至於天氣的變化都有影響到豆子的烘焙,本研究僅以烘焙機滾筒的攪拌葉片設計做為探討,延續黃義鈞學長的數位研究,以實體模型製作來觀察驗證攪拌葉片設計的影響,透過觀察分析記錄,發現問題,提出滾筒葉片的改善設計。

並列摘要


If coffee beans are not roasted, they are just mundane red fruit seeds. After being roasted, coffee beans are reborn. With more and more people drinking coffee in Taiwan, the coffee market in Taiwan getting mature. The population of drinking coffee has expanded rapidly. They have a higher quality standard and a higher expectation for coffee. As a result, specialty coffee is now on the market. According to the places of coffee production and the kinds of coffee beans, coffee beans are roasted to varying degrees. They will produce different kinds of flavors and contain different kinds of personalities. So how to maintain a consistent roasting quality is quite important. The factors affecting the roasting quality are various, such as beans themselves, coffee roaster machines, roasting fire source type, roller design, time control, and even changes in the weather. Based on a previous digital , the study only aims to discuss the stirring blade do s roaster roller. First,a practical model will be made and used to verify the design result of the stirring blade. Second,observe, analyze,record and then identify problems. Finally, bring up a direction of how to improve the roller blade.
