The present invention relates to an apparatus for extracting liquid from a humid mass. The apparatus comprises a cylindrical housing having a first and a second end wall and a cylindrical side wall. At least one inlet is provided for admitting said humid mass in the housing. A pumping system is also provided for forcing said humid mass into the inlet. A rotor has one or more pairs of side walls, which are joined to a bottom wall and define one or more channels open at their periphery in at least a portion thereof. One or more rotor side walls are provided with perforations. The rotor has a central shaft for rotation with respect to the housing, this shaft having a conduit extending longitudinally therethrough, and is provided with one or more draining conduits having a first portion in fluid communication with the perforations. One or more rotor side walls are moved upon rotation of the central shaft. The draining conduit has a second portion in fluid communication with the shaft conduit. A drive is connected to the shaft for rotating the rotor and the apparatus is provided with one or more outlets for discharging matter containing a reduced percentage of liquid therein upon rotation of the rotor, the channel being in direct communication with the shaft conduit. |
