Abstract: 본 발명은 한약재를 증숙, 원심력에 의해 생약을 추출하는 원심분리형 한약추출기에 관한 것이다. 
     종래의 한약추출기는 한약재를 투입하는 용기내부로 회전축이 관통설치되고, 상기 회전축은 상부의 뚜껑체나 하부에 설치된 모터에 직결되며, 본체의 하부에는 단일의 완충부재를 설치하여 모우터의 진동을 완화하도록 하였으나 상기 뚜껑체는 하중과 축결합관계로 여닫는 작업이 불편하고, 한약재를 용기내 투입시 회전축에 간섭되는 문제와 회전축의 상하부로 직결된 모우터에 수분이 유입되어 고장우려가 있게 되는 문제, 모우터의 구동으로 본체에 가해지는 진동을 충분히 완화시키지 못하는 문제 등을 갖고 있었다. 
     이러한 문제를 해결하고자, 본 발명은 본체(5)내의 약재 저장통(20)을 하부에서 연동축(25)으로 지지설치하고, 상기 연동축(25)은 일측 모우터(M)의 구동축(35)에 연계구동되도록 하여 상기 뚜껑체(7)을 여닫거나 약재 저장통(20)내에 한약재를 투입하는 작업이 용이함은 물론 모우터(M)로 수분이 유입되는 것을 방지하고, 
     상기 본체(5) 하부에는 수거공(6)을 추출펌프(P)와 연결하여 한약재에서 추출한 액상의 생약을 수거하는 작업이 신속,용이하며, 본체(5)에 가해지는 진동을 본체의 무게중심으로 설치된 1,2차 완충기구(44),(48)에 의해 다단으로 완화하도록 하므로 모우터(M) 회전구동시 전달되는 진동을 최소화하여 사용상의 안전성을 우수하게 제공하는데 그 특징이 있다.
