Patent ID: 8221301

Claim:
A centrifuge rotating about a rotation axis to separate a material, comprising: a container coupled to the centrifuge to freely pivot upward and downward on a pivoting axis vertical to a rotation plane, the container having an opening at an upper end thereof and holding a material inside; an angle adjuster raising a central axis of the container beyond a perpendicular angle with the rotation axis while the centrifuge is rotating in order to position the opening of the container downward with respect to the rotation plane and point an end of the container opposite to the opening upward with respect to the rotation plane, thereby allowing a portion of layers formed during centrifugal separation of the material to flow down through the opening and be discharged out of the container; and a casing surrounding the container and the angle adjuster, being fixed to rotatably support the rotation axis, and having a holding portion formed in the casing; wherein the holding portion holds the material that flows down through the opening out of the container.
