An apparatus for extracting liquids from a slurry formed of liquids and fibers, like diluted manure or paper mills residue. The apparatus has a rotatable drum covered with a resilient layer. The apparatus also has two draining rolls which are pressed against the drum so that the slurry passing in between is squeezed. Each roll has a hollow cylindrical shell with a uniform distribution of openings. Each roll also has a perforated filter screen fixed to is. The screen has perforations evenly distributed so that only some perforations lie over the openings in the shell. The perforations are smaller in size than the openings. The apparatus also has a pair of wipers in order to wipe the fibers out of the draining rolls and guide the liquids collected in the shells towards a liquids outlet. A reservoir can be mounted above the drum and upper draining roll for receiving the slurry, storing it to build-up a constant pressure, and supplying it in a continuous manner. An endless screw can also be mounted on top of the drum to scrape the fibers that may remain attached.
