The present invention relates to a coffee roaster, and more specifically, to a cylindrical shape, a plurality of holes are formed in the main wall, and a drum (2) having a driving shaft (201) formed on the rear side is provided therein, and an input hopper (102) on the front side. The green bean input portion 101 is formed to be connected to enable the green beans to be supplied into the drum 2, and the drum is formed by forming the discharge portion 103 provided with an opening and closing door 104 in the lower portion of the green bean input portion 101. (2) a main body 1 capable of discharging the coffee beans therein； The drive unit 3 is installed to drive the motor 301 behind the main body 1 by connecting the rotating shaft of the motor 301 and the drive shaft 201 of the drum 2 protruding out of the main body 1 with a belt. Wow； A heating unit (4) for heating the drum (2) by installing a gas burner (401) to be put under the main body (1)； In the coffee roaster is installed in the lower portion of the front surface of the main body (1) consisting of coffee beans (5) for collecting the coffee discharged from the discharge portion 103, A coffee bean bowl 5 having a bottom formed of a porous plate 501； An intake cylinder 601 installed at a lower portion of the bean hopper 5 to suck external air through a hole of the porous plate 501； After the roasting by including a cyclone (6) connected to one side wall of the intake cylinder 601 by a duct (7), the air intake in the intake cylinder 601 by a blower 602 formed in the upper end By allowing the coffee beans to be cooled down quickly, the roasting quality is improved to produce more delicious and flavorful coffee beans.본 고안은 커피 로스터에 관한 것으로 보다 구체적으로는 원통형으로 되어 주벽에는 다수의 구멍을 형성하고, 후면에 구동축(201)을 형성한 드럼(2)을 내부에 설치하고, 전면에는 투입호퍼(102)와 이어진 생두투입부(101)를 형성하여 상기 드럼(2) 내부에 생두를 공급 가능케 하고, 상기 생두투입부(101)의 하부에는 개폐문(104)이 설치된 배출부(103)를 형성하여 상기 드럼(2) 내부의 원두를 배출할 수 있게 한 본체(1)와； 상기 본체(1) 후방에 모터(301)를 설치하여 모터(301)의 회전축과 상기 본체(1) 외부로 돌출 형성된
