The present invention relates to a coffee bean roasting device, which mainly provides a hot air source blown by the hot air hole to blow the coffee beans when the coffee beans are baked, so that the coffee beans are suspended. The suspended state is due to the blowing of the hot air source, and the shapes and weights of the coffee beans are different, so that different degrees of tumbling state are generated, and the second heat source mechanism is received into the barrel of the baking cylinder. When the heat source is in a mixed state, it is relatively uniform in heat.本新型創作係關於一種咖啡豆烘焙裝置,主要係提供當內置咖啡豆而進行烘焙時,該熱風孔所吹驅之熱風源對咖啡豆形成吹驅,而令該等咖啡豆形成懸空狀態,而該懸空狀態係由於該熱風源之吹驅,而由於各個咖啡豆形狀、重量不等,因此產生不同程度之翻攪狀態,相對使其接受到該第二熱源機構朝向該烘焙筒之筒內之熱源時,處在一種混動狀態,而使得其受熱相對較為均勻。
