Centrifuge separating fluids by adjusting rotation speed using rotator and centrifuging method of the same

A centrifuge comprising:

• a rotator comprising a receiving unit receiving materials and guiding the materials to move upward by centrifugal force to an upper portion of the receiving unit, and a rotator cover covering the upper portion of the receiving unit;
• and
• a container that is coupled to the rotator cover to be connected to the receiving unit and that receives the materials moved upward along the receiving unit,
• wherein the receiving unit comprises a vertical guiding portion whose horizontal cross-section becomes reduced downwardly such that the materials received in the receiving unit flow upward by centrifugal force,
• wherein the receiving unit further comprises a horizontal guiding portion that is inclined upward from an upper end of the vertical guiding portion and extended to the outside, and
• the horizontal guiding portion comprises at least one convergent portion where the centrifugal force is maximal such that the materials moved upward from the vertical guiding portion move along an inner wall of the horizontal guiding portion and converge into the convergent portion by centrifugal force.
