    (54) Apparatus for separating liquid and solid substances, in particular for extracting juice from fruit and the like


    (57) A grape press constituted by a cylindrical or truncated-cone tank (3) provided with a series of semi-elliptical partitions (11) adapted to form, together with respective membranes (15), a plurality of pressure chambers (13). Successive pressing regions (23, 25, 27), with related discharge devices (21, 31, 33, 35), are arranged parallel to the pressure chambers. The product is fed continuously at one end of the tank and is advanced by rotating the tank, since the partitions are arranged so as to form a half-helix. The pressure chambers and the pressing regions are actuated alternatively in order to perform the intended pressing cycles.
