The present invention relates to a cornus officinalis thresher having a simple structure capable of separating seeds from pulp of cornus officinalis, which is used as a medicinal herb, in a limited space. The cornus officinalis thresher provides cornus officinalis to a flat roller installed with an interval from a spiral roller having a spiral groove and subsequently, the pulp of cornus officinalis is discharged between the rollers and the seeds are discharged sideways aboard the roller. Another pair of spiral roller and flat roller are installed so as to be symmetrical with the aforementioned spiral roller and flat roller. One spiral roller of the two spiral rollers is provided with power, and the other spiral roller and the flat rollers are connected to power via a spur gear, and the spiral rollers and flat rollers are configured to rotate in the shape engaged with each other. Cornus officinalis is supplied to a hopper between the spiral roller and the flat roller. The hulled pulp is discharged from a front discharge hole arranged between the spiral roller and the flat roller of which seeds are discharged from a lateral discharge hole aboard the spiral roller. A press bar is arranged in the upper part between the spiral roller and the flat roller wherein the press bar is enabled to move horizontally by an elastic force of a spring in a staggered form. One side of the press bar comes into contact with a protrusion surface having an oblique angle which is formed inside a pulley transmitting a motor power to the spiral roller. A press piece is fixated downwardly in the press bar so as to press cornus officinalis between the spiral roller and the flat roller.COPYRIGHT KIPO 2015본 발명은 한약재로 사용되는 산수유의 씨앗을 과육과 분리시키되 좁은 공간에서 간단한 구조로 많은 량의 산수유를 탈피시키는 산수유 탈피기에 관한 것이다.본 발명은 나선형 요홈이 형성된 나선형 롤러와 일정 간격을 두고 수평으로 설치되는 평롤러 사이로 산수유를 공급하여 산수유 과육은 롤러 사이로 배출되고 씨앗은 롤러를 타고 측면으로 배출되는 산수유 씨앗 분리기에 있어서, 상기 나선형 롤러와 평롤러에 대칭되는 나선형 롤러와 평롤러를 설치하되 하나의 나선형 롤러에만 모터의 동력을 전달하고, 상기 나선형 롤러와 평롤러는 평기어를 통하여
