Abstract: A self-emptying centrifuge drum has a collecting channel for emptying the drum and a fitting for introducing water into the collecting channel. The drum is rotatable and is hydraulically actuatable by water introduced into the collecting channel through the fitting. The collecting channel rotates with the drum about an axis of rotation and the fitting is stationary and has at least one outlet. A baffle extends up from below the collecting channel and between the collecting channel and the fitting and has a lower portion below the collecting channel and an upper portion extending into an area radially inward of the collecting channel with respect to the axis of rotation. The at least one outlet of the fitting is aimed at the lower portion of the baffle.
