Claim:
A centrifuge, comprising: a distributor for introducing material to be centrifuged; a sieve system in a centrifugal compartment of a centrifugal drum, the sieve system having a plurality of axially mutually offset membrane plates, the membrane plates being arranged radially with respect to the distributor and having at least two axially-spaced membrane disks with the disks connected with each other by at least one plate spacing ring in an area of the disks' outer circumference; the sieve system having a gap between adjacent membrane plates the gap having an inlet at an inner periphery and an outlet at an outer periphery and arranged such that a flow direction of the material to be centrifuged emerging from the distributor onto the membrane plates and exiting the gap into the centrifugal compartment and a flow direction of particles to be deposited on the membrane plates are identical; and a piston slide valve for closing the centrifugal drum.
