The present invention offers a method for separating dry matter from a medium. A separation chamber is at least partly defined by a plurality of rollers (2,7) and is capable of being pressure regulated. At least one of the rollers is a pore roller (7) having a surface with pores allowing permeability for the medium covered with a filter (3) and furthermore having at least one' channel in fluid contact with the pores of the surface. A pressure difference is established across the filter (3) and both, the filter (3) and the filter cake is passed through the rollers (2,7), whereby the medium is separated from the filter cake.
