Abstract
A discontinuous centrifuge has a rotatable centrifuge drum with a casing. The cylindrical centrifuge casing is provided with holes to discharge a liquid produced during the centrifugation. The holes have a cross-section with an elliptical shape. The cross-section of the holes is widened from the inside to the outside. The hole wall is continuous in this case. The diameter of the cross-sections of the holes parallel to the drum axis on the inside of the casing is equal to the diameter of the cross-sections of the holes parallel to the drum axis on the outside of the casing. The diameter of the cross-sections of the holes in the peripheral direction, on the other hand, on the inside of the casing is smaller than the diameter of the cross-sections of the holes in the peripheral direction on the outside of the casing. The area of the elliptical holes may be additionally also divided by webs.
