Abstract
Description
本發明係有關於一種咖啡豆烘焙機，尤指一種可將咖啡豆烘焙時產生濃煙、熱氣排出於外及使烘焙後的咖啡豆快速冷卻之咖啡豆烘焙機。The present invention relates to a coffee bean roasting machine, in particular to a coffee bean roasting machine that can emit thick smoke and heat when roasting coffee beans and quickly cool the roasted coffee beans.
按，咖啡生豆沒有咖啡香，需經過烘焙才可產生獨特風味及口感，烘焙過程係利用高溫將咖啡生豆所含水分蒸發，以使咖啡豆焦糖化並產生梅納反應，進而使咖啡豆內的芳香物發生多樣化學變化，以製作出具濃郁香味的咖啡豆。Press, green coffee beans do not have a coffee aroma, and they need to be roasted to produce a unique flavor and taste. The roasting process uses high temperature to evaporate the moisture in the green coffee beans to caramelize the coffee beans and produce a Mena reaction, thereby making the coffee beans The aromas inside undergo diversified changes to produce coffee beans with a strong aroma.
而於咖啡豆加熱烘焙過程中，係會產生濃煙及熱氣，該濃煙及熱氣會瀰漫、散布於室內，造成室溫升高及室內環境污染。再者，當完成咖啡豆烘焙後，為避免咖啡豆維持高溫破壞烘焙後風味，故將咖啡豆由烘焙甕倒出後，會將咖啡豆置於常溫讓其自然冷卻，然該冷卻過程通常長達數小時，而此緩慢的冷卻過程不僅浪費時間，且會降低咖啡豆烘焙後的品質。During the heating and roasting process of coffee beans, thick smoke and hot air will be generated. The thick smoke and hot air will be diffused and spread indoors, causing the room temperature to rise and indoor environmental pollution. Furthermore, after the coffee beans are roasted, in order to prevent the coffee beans from maintaining the high temperature and destroying the flavor after roasting, after pouring the coffee beans from the roasting urn, the coffee beans are placed at room temperature and allowed to cool naturally. However, the cooling process is usually long. Up to several hours, and this slow cooling process not only wastes time, but also reduces the quality of roasted coffee beans.
緣是，本發明人有鑑於現有咖啡豆於烘焙時會產生濃煙、熱氣，及咖啡豆冷卻時間過長等缺失，乃藉其多年於相關領域的製造及設計經驗和知識的輔佐，並經多方巧思，研創出本發明。The reason is that the present inventors have taken advantage of their years of manufacturing and design experience and knowledge in related fields to assist in the lack of smoke, hot air, and excessive cooling time of coffee beans during roasting. Ingenious ideas, research and creation of the present invention.
