Definitions

  • the pressing of grape husks or of grapes serves to separate the wine or must from the solid parts.
  • diaphragm presses shown diagrammatically in cross section form in Fig. 1, this is achieved through the use of compressed air that presses, with the aid of a flexible diaphragm (1), the grape husks (2) against a wall (3) from the holes in which the liquid obtained passes into the cavity between this and an inner wall of the container (4), and is then sent outside.
  • the container (4) is provided with an aperture (5) complete with a corresponding cover (6), for charging the grape husks.
  • the container (4) can be placed in rotation around the longitudinal axis (7) (Fig. 2). After a certain pressing time has elapsed, it can be seen that solid substances carried forward block the streams in which the must flows. By removing the pressure, sucking the diaphragm towards the container and causing the whole unit to rotate around the longitudinal axis (crushing stage), the said streams are set in motion again.
  • the object of the invention is to provide a diaphragm press that has one or more apertures for the charging of the grape husks, placed longitudinally almost along the. full generatrix of the container in such a way as to offer overall more ample entry to the inside of the press.
  • the said greater entry possibility permits a more immediate and uniform distribution of the grape husks in the inside of the press and allows the use therewith of a charging hopper, placed in the region of the said apertures and so shaped as to let the grape husks drain satisfactorily under natural pressure prior to their being inserted.
  • a further object of the invention is to provide the inside of the container with two separate chambers for the charging of the grape husks, each provided with a flexible diaphragm on one side, and with a drilled wall on the other, so as to break down the mass of grape husks to be pressed under the action of the diaphragm.
  • the improved diaphragm press forming the subject of the invention which, from a general point of view, is characterized by the fact that the said press is provided longitudinally with one or more apertures, fitted with corresponding doors, that extend over almost the full length of a generatrix of the said container and communicate internally therein with a chamber; provision being made for a charging hopper placed above the said apertures, the lateral and back walls of which are connected internally to drilled sheet metal elements and form a hollow communicating with a draining channel for the discharge of the naturally pressed must, that can be removed in order to open the said back walls downwards; the inside of the said hopper being provided with panels placed vertically, connected to the said back walls in such a way as to accompany them, at the time they are being opened, without obstructing the grape husk discharge port.
  • the said container has internally two flexible diaphragms placed almost centrally, each of which faces, on opposite sides, a drilled sheet metal plate that is placed in close contact with the inner walls of the container and forms therewith a cavity for the discharge of the must, each diaphragm and each corresponding sheet metal plate defining a chamber for the charging of the grape husks; between the said diaphragms there being a baffle, placed along the diameter thereof, fastened to the said container and corresponding centrally to the said apertures, constituted by two drilled walls that internally create a hollow that communicates with the means for supplying the compressed air.
  • a further characteristic, according to another preferred form of embodiment for the press in question, is that two diaphragms are placed, on opposite sides, almost in close contact with the inner surfaces of the said container, and that a pair of opposite, drilled, sheet metal plates placed along the diameter of the said container, corresponding centrally to the said apertures, form between them a hollow for the discharge of the must; means being provided to send compressed air in between the said diaphragms and the walls of the container opposite thereto.
  • FIG. 5 Another solution for achieving the total longitudinal opening is that shown diagrammatically in Fig. 5, consisting in dividing the container into two, almost identical, shells (13) and (14) connected one to the other at the corresponding lower extremities (15), which are provided, all along the contact extremities thereof, with a sealing gasket (16).
  • all the walls (18), including the back walls (19), constitute with an internal drilled sheet metal plate (20), a hollow cavity.
  • a draining channel (21) for discharging the must obtained from the natural pressure draining of the grape husks, is made in a way in which it can be removed in order to allow the back walls (19) to be rotated downwards and the hopper to be opened.
  • Two panels, made of drilled sheet metal, are placed longitudinally in the hopper, secured to the said back walls (19) so as to accompany them during the opening stage without obstructing the discharge port of the grape bucks, their purpose being to improve the draining, and these are removable in the event of non-crushed grapes being used.
  • FIG. 7 Another improvement results from the shortening of the path towards the outside followed by the must when leaving the mass of grape husks. Since the pressing speed is somewhat limited, time is, in fact, saved by reducing the path followed by the must.
  • the solution is depicted diagrammatically in Fig. 7 wherein the container (4), again rotatable as in all diaphragm presses for grapes, carries inside a drilled sheet metal plate (23) close up against the walls thereof.
  • Two flexible diaphragms (24), depicted in the vacuum stage, are placed in a central position at the time of charging via the aperture (5) that can be closed by the door (9), or during the crushing stage,and when compressed air is sent between them, through a baffle (25) constituted by two drilled walls positioned along the diameter of the container, in the region of the said aperture (5), between the said diaphragms, they expand and go and compress the grap husks present in the chamber (26) up against the drilled sheet metal plate (23).
  • FIG. 8 Another possible form of embodiment is depicted diagrammatically in Fig. 8 wherein the container (4) is provided internally with two diaphragms (27) and a pair of opposite, drilled, sheet metal plates (28) that form between them a cavity for the flow of must, these being placed along the diameter of the container, in the region of the said aperture (5).
  • the air under pressure is sent between the inner walls of the container (4) and the diaphragms (27) opposite thereto, in order to compress against the drilled sheet metal plates (28), the grape husks charged in the two chambers (29).
  • the charging naturally takes place through the longitudinal aperture (5) that can be closed by the door (9) again provided with elastic sealing elements (10).
  • the crushing of the grape husks achieved with the said two solutions is improved because of the fact that there is no internal rolling of the grape husks, and thus the quantity of solid substances carried forward is less.
  • the first compression occurs, in fact, with the central baffle in a horizontal position, and thus the distribution of grape husks attached to the baffle is bettered.
  • the use of a vacuum in addition to the compression causes the air interposed in the vacant spaces in the crushed grape husks,when sucked up, to reopen the must flow channels.
  • a vacuum can be obtained by closing the discharge of the must and placing the chamber in communication with the diaphragm vacuum apparatus. This can also be achieved with continuity by discharging the must ooaxially with the axis of rotation and by applying a constant vacuum throughout the grape husk compression stages.
  • channels and ducts for sending air under pressure or for eventual operating necessities, that pass coaxially to the axis of rotation or laterally to the container, have been omitted.
