Definitions

  • Flexible diaphragm presses employed for liquid producing material such as grapes, mixed fruits and the like are well known in the field, they are made up of essentially a cylindrical countainer capable of rotating on its own longitudinal axis and having on the outer plating one or more loading doors, besides having the possibility of loading through a shaft placed in correspondance to the rotation axis and containing inside it a flexible diaphragm made up of a flat sheet substantially sack shaped fitted to adhere to half of the internal wall of the container.
  • the edge of the flexible diaphragm is fixed to the container along the periphery of a plane lying in correspondance to the rotation axis of the container, and therein the squeezing pressure is obtained blowing pressurized air which slowly increases to reach a maximum pressure of 2 bars between the walls of the container against which adheres the diaphragm.
  • Patent CH 412.577 proposes a revolving cylindrical container fitted on a framework support on the median axis and perpendicular to the longitudinal axis with a flexible diaphragm on the external wall of the internal projecting part where the material that is to be pressed is positioned in the interspace between the hood and the external wall.
  • the rotation around the median axis carries out the function of loading the material that is to be pressed, by means of the upper cover, and delivering the residual after the pressing operation has finished, by means of the lower cover.
  • This device will not allow material to be crushed both because of the manner in which the material is arranged so that will tend to pack-up against the bag filter and because of the manual rotation.
  • the patent UK 2.158.697 supplies a small spherical press, about as big as a football, containing a flexible bag, closed by a door on the upper part and that delivers on the opposite part by means of bored conduit, positioned in the center of the sphere.
  • the spherical shape of the flexible bag cannot press the squeezed material to the end and can only be received in small devices, like those proposed in this patent.
  • the invention consists in foreseeing a cilindrical container arranged on a support which is made to turn according to its median axis perpendicular to the longitudinal axis, with a sack shaped diaphragm where the material that is to be pressed is introduced and with a bored conduit to collect and convey the liquid outside the container positioned in correspondence to the longitudinal axis, characterized by the flexible diaphragm bag covering and adhering to the entire internal surface of the container - plating and bottom units - apart from the loading door area, positioned in correspondence to one of the bottom units, with a bored conduit that collects and conveys the liquid outside the container and fitted at the two delivery conduits and of the liquid from the pressing in correspondence to the center of the two cylinder bottom units; with the container positioned in order to revolve around the supports and of a framework support by means of pivots and in order to determine, by means of the alternation of the pressing operation and the rotation of the container, the crushing of the material, in order to squeeze the material well, even under very low
  • the diaphragm press is made up of a cylindrical tank 1, having a reinforcement ring 2 and pivots 3 and 3', arranged on supports 4, 4', in correspondance to the median axis A-A', to allow the rotation of the tank 1 around its own median horizontal axis, the rotation of which is obtained by known means using an electric motor and its relative reducer 6.
  • the tank 1 has one of its two ends, equipped with a door, for the loading of the material to be squashed and conduits for the discharging of residual material after squashing, and houses a coupling 8, in correspondance to the longitudinal axis B-B' - see also fig. 3 - obtained in the door 7, and symmetrically in the centre of the bottom, a second coupling wholely threaded 9 - see also fig. 5 - into which is introduced an end of a cylinder shaped drainage conduit 10 the section being of any shape circular, polygonal etc.
  • Coupling joints 8 and 9 in the part protruding from the tank are externally threaded to each receive a butterfly valve not illustrated, to prevent the emission of the liquid from the tank.
  • the drainage conduit 10 has bores on its surface to allow flowing of the liquid only while retaining the solid parts for example as reguards grapes, the pips and skins.
  • a sack shaped flexible diaphragm 12 which covers and adheres to the entire internal surface of the container except for the part corresponding to door 7.
  • This diaphragm is connected to the part of the door with its tip to the lower part of a flange 15 by means of a counter flange 16 - see fig. 4, - and in correspondance to the end between the two flanges 17 and 18.
  • Flange 15 is then suited to meet with flange 19 above belonging to door 7 to close this part of the container with bolts, or with other know means such as automatic hooks or a bayonette system.
  • Both the conduit 20 and the conduits 21/21'/21''/21'' are bored along its surface and turned towards the inside of the tank, which in turn is bored in correspondance to it.
  • Said drainage conduits can be arranged outside the tank as shown in fig. 2, indifferently inside it according to another form of realization or even obtained as a result of the shaping of the plating of the container.
  • the pressing process using the press according to the invention is therefore obtained by blowing compressed air slowly increasing in pressure between the internal wall of the container and the external wall of the diaphragm through appropriate conduits 20/21 which, due to their particular characteristics allow a uniform distribution alternating the operation with the production of a vacuum still between the internal wall of the container and the external one of the diaphragm, so that the diaphragm at the stage of the operation cycle adheres to the walls of the container and the material is, free to crumble as a result of a series of rotations of the container around its axis A-A', as occurs in diaphragm presses of the known type which on the contrary rotate around ther axis B-B'.
  • Another advantage to be underlined is the fact that with the invention the tank being arranged vertically favours and notably increases the draining of the liquid even from the first stage of the loading of the material to be processed as a consequence of a higher hydrostatic pressure generated on the lower lying material, considering that the tank is in a vertical position during loading stage.
  • the system facilitates the crushing of the material to be squeezed, grapes in particular, an operation which requires less rotations of the container respect to the number of rotations necessary in normal presses having horizontal tanks.
  • the device consists in connecting one of the two supports and rotation pivots 3' of the tark 1, which in this case must be hollow, to a tubing 101 corrected by means of tube bend 102 to loading door 7 of the press, adding on the outerportion of said concave pivots a rotating joint 103 to which is connected a tubing deriving from a feeding pump for the must and grape skins.
