Abstract: 본 발명은 부엌 쓰레기 중에 분쇄 곤란물이 혼입되어 있는 경우라도, 날의 파손이나 장치의 운전 정지를 초래하지 않는 분쇄기를 제공한다. 
     본 발명에 의한 분쇄기(1)는 부엌 쓰레기가 투입되는 투입통과, 투입통의 하부에 접속된 케이싱(28)을 구비하고 있다.  케이싱(28)의 내부에는 구동모터(36)에 의해 회전 구동되는 원판(31)이 수용되어 있다.  원판(31)에는 원주방향을 따라 90도마다 배치된 네 개의 회전날(41)이 고정되어 있다.  케이싱(28)은 원판(31)과 대향하는 상판을 구비하고 있다.  상판에는 회전날(41)과 대향하는 타원 고리모양의 고정날(42)이 고정되어 있다.  원판(31)이 회전하면, 회전날(41)은 둘레를 돌아 이동을 하고, 회전날(41)과 고정날(42)과의 교차 각도(θ)는 연속적으로 변화된다.
