This creation is a kind of baking beans machine, is using made by a roller and a hot wind generation machine. Wherein, the gas in tube body tube body is heated using the electric heater in hot wind generation machine, then generates the wind-force toward the air inlet direction by wind-force generator, the gas push in tube body is entered into the roller. Thereby, it can will concentrate the gas of heating Hou that will spread in the what roller, so that each coffee bean can all be toasted in mutually synthermal space, known thermal energy concentrations what barrel is overcome to cause different with the ripe degree of batch coffee bean and tend to have and burn coffee bean and the problems such as general electric heating dries beans machine power consumption vastly, efficiency is bad.本創作為一種烘豆機，其係利用一滾筒與一熱風產生機所製成。其中，利用熱風產生機中的電熱器加熱管體管體內之氣體，再藉由風力產生器產生往該進風口方向之風力，將管體內之氣體推送進入該滾筒。藉此，可將集中加熱後的氣體將散佈於該滾筒內，使得各咖啡豆皆可以在相同溫度的空間中進行烘烤，克服習知熱能過度集中於筒壁造成同批咖啡豆熟度不一及易有燒焦咖啡豆及一般電熱烘豆機耗電量鉅大、效率不好等問題。
