Publication number: 20110120323Abstract: A press is provided including a perforated draining drum; a juice collecting vat on a bottom of which the perforated drum is rested; a mobile member, located above the drum and activated with a vertical movement by powering device; a presser plate, which descends in the drum, to press the load; raising mechanism for raising the drum to extract the pressed product residue. The press also includes: a stem, carried by the mobile member, having a lower end to which the plate is fixed and having a variable length between a maximum and a minimum length which is reached following descent of the mobile member and an elastic member acting on the stem to increase its length, thereby displacing the residue of pressed product out of the drum. The residue is evacuated automatically by simple bodies which do not require operating liquids which might undesirably fall into the collecting vat.Type: ApplicationFiled: November 19, 2010Publication date: May 26, 2011Applicant: DIEMME S.P.A.Inventors: Matteo COMANDINI, Massimo MELANDRI

Patent number: 5094158Abstract: A diaphragm press comprises a cylindrical vessel (7) rotating about its longitudinal axis and divided into two diametrically opposing parts by a flexible diaphragm (8). A series of perforated longitudinal channels (10) is fixed to a part of the inner surface of the vessel and connected at one end to an external manifold (12) for collecting the juice. At their other end, the channels (10) are connected to at least one further manifold (15) which is connected to a pumping unit (99) for feeding water under pressure by way of valves (160). The flexible diaphragm (8) is of such dimensions as to perfectly mate with the wall to which the channels (10) are connected and with the channels themselves so as to perfectly close the holes (100) of these channels (10) when the diaphragm is thrust from its rear by the pressurized fluid.Type: GrantFiled: September 26, 1991Date of Patent: March 10, 1992Assignee: Diemme S.p.A.Inventors: Francesco Melandri, Primo Melandri
