A coffee bean roaster comprises a cylinder-shaped housing, a roasting vessel, a hemishpere-shaped lid, a guiding duct and a handle duct. The housing has a duct connections part protruded in one side. Corresponding to the housing, a lower plate is formed on a bottom face. A partition plate is formed in an upper end. A placement part having air inducing holes is placed above the partition plate. A fan is installed. A heater upper plate and a heater lower plate are placed in the upper end of the placement part. A heater coil is placed between the two plates to form a heater assembly. Corresponding to the roasting vessel, a guiding part is placed at the bottom face of a heated air blower. Blowing holes are formed on the outer perimeter surface of the heated air blower in the oblique direction, a spindle is formed therein. The coffee bean roaster has an excellent roasting capacity by a strong whirlwind, and easily removes the hulls of the raw beans. The power consumption can be reduced by 30-40% by re-using waste heat generated inside the roasting vessel without exhausting it outside. This invention is small and simple in size, convenient in use, and low in sound during use. Accordingly, the present invention can be easily assembled and disassembled, and the packing and carrying of the product is convenient. Furthermore, the production cost is lower than before by 30-40%.
