A kind of roaster for coffee bean of what is closed in this creation, and it includes a body, an air blower, a heater and a coffee bean containers. There is a venthole on the body. There is a guide duct, the exportable air-flow with wind pressure of the air blower is sent into the guide duct and is flowed out by the venthole between the air blower and the venthole. The heater is mounted on the air-flow heating on the pipeline of the guide duct to be exported to the air blower. The inside of the coffee bean container is for coffee bean receiving, the coffee bean container is used to be placed on above the venthole of the body, the bottom end of the coffee bean container has a under shed, the inside of the coffee bean container is equipped with a bottom plate and places to provide coffee bean, the bottom plate is one angle of nonparallel inclination with respect to the axial direction of the coffee bean container, and the lower part of the bottom plate is equipped with plural air hole. When the coffee bean container is placed on Hou on the body, the air-flow which is exported can enter in the coffee bean container from the venthole, and the coffee bean circulative convection that allows in the coffee bean container is baked.本創作關於一種咖啡豆烘焙機，其包含一機體、一鼓風機、一加熱器、及一咖啡豆容器。該機體上具有一出氣孔。該鼓風機與該出氣孔之間具有一導風管，該鼓風機可輸出具有風壓的氣流送入該導風管且由該出氣孔流出。該加熱器安裝在該導風管的管道上用以對該鼓風機所輸出的氣流加熱。該咖啡豆容器的內部可供咖啡豆容納，該咖啡豆容器用來放置在該機體的出氣孔上方，該咖啡豆容器的底端具有一下開口，該咖啡豆容器的內部設有一底板用以提供咖啡豆放置，該底板相對該咖啡豆容器的軸向為非平行的傾斜一角度，且該底板的下部設有複數透氣孔。當該咖啡豆容器放置在該機體上後，該鼓風機所輸出的氣流可從該出氣孔進入該咖啡豆容器內，讓該咖啡豆容器內的咖啡豆循環對流來進行烘焙。
