The present invention is a coffee bean roasting machine. During the baking process, when the coffee bean is inspected, a part of the coffee beans in the tank of the coffee roasting machine is taken through a test piece, and then the inspection piece is directed to Pull out and inspect the coffee beans in the test piece to confirm whether the baking is completed. In addition, a lifting device is arranged under the tank, and a heating energy supply device is arranged on the lifting device when the coffee beans are baked in the tank. The temperature at the time of baking can be adjusted by adjusting the lifting device. According to the above configuration, when the coffee beans are roasted, the coffee beans can be inspected more quickly and conveniently, and the temperature of the roasted coffee beans can be adjusted.本創作係一種咖啡豆烘焙機之結構,於烘焙過程中,進行咖啡豆檢驗時,經由一檢驗件擷取於該咖啡豆烘焙機之一槽體內之部分咖啡豆,接著再將該檢驗件向外拉出,並檢驗該檢驗件內之咖啡豆,確認是否完成烘焙,此外該槽體下方更設置一升降裝置,該升降裝置上設置一熱能供應裝置,當咖啡豆於該槽體內進行烘焙時,其能夠藉由調整該升降裝置來調整烘焙時的溫度,經由上述之結構,於烘焙咖啡豆時,能夠更快速且便利地檢驗咖啡豆以及調整烘焙咖啡豆之溫度。
