Definitions

  • the present invention concerns an apparatus and a method suitable for pressing several kinds of fruit, particularly grapes, keeping the latter under controlled atmosphere, specifically a poor in oxygen atmosphere.
  • pressing is carried out through suitable pneumatic presses, comprising a cylindrical tank that is arranged in a horizontal position and motorized in order to rotate on a longitudinal axis thereof by means of end hubs.
  • the inner wall of the tank is divided along a diametral plane of the tank by an anchoring portion of an expandable pressing membrane.
  • the membrane defines, on one side, an operating chamber having a variable volume and, on the other side, a pressing chamber for the material to be squeezed.
  • the pressing chamber holds a set of ducts for draining the squeezed product, said ducts being arranged longitudinally of the inner wall of the tank.
  • Each duct consists of a perforated curved plate having an L- shaped cross section.
  • the liquid squeezed product is convoyed by each duct towards a respective outlet leading outside the tank.
  • the material to be pressed (grapes, elderberries, raspberries or other kinds of fruit) , which can be integral, crushed, stripped or picked off the bunch, is brought through at least one opening of the pressing chamber, said opening being positioned on the side wall of the tank. Presses are also known in which the material to be pressed is brought into the pressing chamber through an opening that is positioned in one of the end walls of the tank substantially at one of the hubs (axial feeding) . These presses carry out a pressing cycle comprising at first insufflating compressed air into the operating chamber, i.e.
  • the membrane when becoming inflated, through pressures rising in a progressive manner compresses and squeezes the above-mentioned material, thus extracting therefrom a liquid that is drained outwards by the ducts. Then, the previously insufflated air is sucked by a vacuum pump and the membrane comes back to its starting position, i.e. sticking to the inner wall of the tank. In this phase, air is sucked from the outside through the openings of the tank.
  • the press rotates in an axial manner so as to cause solid compressed material to crumble by falling towards the membrane, which clears the ducts from solid residues of squeezing.
  • anti-oxidizing gases are "disposable", i.e. the amount of anti-oxidizing gas that is used for each pressing cycle is wasted whenever the membrane is expanded in the pressing chamber (see, for example, EP 0524373) .
  • An aim of the invention is to improve apparatuses and methods for pressing fruit of various kinds, particularly grapes.
  • An other aim is to provide an apparatus and a method that enable fruit of various kinds to be pressed substantially avoiding exposing to atmospheric oxygen the vegetable mass that is subjected to pressing.
  • Figure 12 shows an interrupted side view of an upper front portion of the pneumatic press of Figure 9;
  • the vat 10 is below connected by a draining pipe 14 with a container 12, in which the must is collected in order to be sent to the subsequent processing phases through an exhaust duct 16.
  • the first wall 20, the second wall 21 and the side wall 24 end below in a mutual airtight sealing edge 32 on the upper opening of the vat 10.
  • the container 12 is airtight sealed on the draining pipe 14 by a lid 34.
  • the external portion 52 of the rotary manifold 54 and the intermediate ducts 50 are integral with the tank 5 and thus they rotate together with the latter.
  • the external portion 52 develops in annular manner at a certain distance from the hub 8, said external portion 52 comprising an inner wall 58, fitted onto the hub 8, and an external wall 53, getting the intermediate ducts 50.
  • a first annular wall 56, facing towards the end wall 4 connects the inner wall 58 and the external wall 53 of the external portion 52.
  • the latter has a C-like shaped cross section turned in a direction which is opposite to the end wall 4.
  • An inner portion 60 of the manifold 54 is held inside the external portion 52, at the opposite side of the first annular wall 56.
  • the proximal portion 153b which is circular sector-shaped, runs at first parallel and then orthogonal to the rear wall 156, finally joining on the latter. So, two rectilinear spouts, not shown, which converge near to the hub 8 and an interposed arched wall, not shown, which has a concavity turned towards the hub 8, are defined between the rear wall 156 and the proximal portion 153b.
  • a further inner portion 160 of the further rotary manifold 154 is admitted inside the further external portion 152, said further inner portion 160 being opposite to the rear wall 156.
  • the further inner portion 160 has a C-like shaped section, said section being opposite to the external portion 152 and contained in the latter.
  • the further inner portion 160 is fixed and enables the further external portion 152 to outwardly rotate so that the liquid product obtained by pressing, which is collected from the further inner chamber 164 through the peripherical openings 130, may then flow through the transfer duct 57 that emerges from the further annular wall 162.
  • the transfer duct 57 carries the liquid product direct to a further container 19, whose structure and operation will be disclosed in detail hereinafter with reference to Figures 9 to 13.
  • the inner annular gasket 66 is placed between the further inner portion 160 and an end portion of the further inner wall 158.
  • the external annular gasket 68 is placed between the further inner portion 160 and an end portion of the further external wall 153.
  • the latter is positioned below the tank 5, near to the end wall 4, and made integral with supporting structures, not shown, of the tank 5.
  • the first flexible pipe 212 leads into a curved drainpipe 217 that continues to a second flexible pipe 218.
  • the second flexible pipe 218 leads into the further container 19 that is connected to a vacuum pump 222 through a flexible duct 221 and further connected to the reservoir 42, above disclosed with reference to Figures 1-3 and 5, through the transit duct 36.
  • An end 258 of the transit duct 36 leads into the further container 19 and is provided with an interception valve 228, e.g. a membrane valve.
  • the liquid product obtained by pressing, once came out of the ducts 6, advances along a path comprising, in sequence, the arched manifold 317, the curved connecters 218 and 219, the first flexible pipe 212, the curved drainpipe 217, the second flexible pipe 218 and the further container 19.
  • the liquid product comes out of the latter through a further exhaust duct 220 and is then conveyed to subsequent processing phases.
  • the first flexible pipe 212 is so long as to accompany the tank 5 during the rotating movements performed by the latter on its longitudinal axis during a pressing cycle. More exactly, the first flexible pipe 212 is so long as to enable the tank 5 to perform four turns altogether, two of which being clockwise and two being anticlockwise. These turns result sufficient to obtain an effective pressing of the vegetable material and a subsequent crumbling of the compacted solid residue that adheres to the inner walls of the tank 5.
  • the first flexible pipe 212 is trailed by the curved connecter 234 that is integral with the arched manifold 317, said first flexible pipe 212 respectively winding round, or unwinding from, a second roller 227 that is coaxial with the hub 8.
  • the assembly comprising the arched manifold 317, the curved connecter 234, the further curved connecter 210, the first flexible pipe 212, the curved drainpipe 217 and the second flexible pipe 218 defines an operating volume that communicates, at one end, with the further container 19 through the second flexible pipe 218 and, at the opposite end, with the pressing chamber of the press 1 through the outlet sections 6a of the ducts 6.
  • This operating volume results isolated from the external environment and it only communicates with the reservoir 42 through the transit duct 36.
  • the must that is produced inside the pressing chamber does not come into contact with the oxygen of the ambient air but with the inert gas contained in the reservoir 42, said must resulting not subject to undesired oxidation.
  • the further exhaust duct 220 of the further container 19 is provided with the level sensors 226 that keep a certain amount of must inside the further container 19 so closing any possible transit of external air through the further exhaust duct 220.
  • the not-oxidizing gas is pushed by the fan 46 along the transit duct 36 towards the press 1, according to a direction FI, thus causing a partial emptying and subsequent collapse of the reservoir 42.
  • This reversible configuration assumed by the reservoir 42 is shown by a broken line.
  • the membrane is expanded and occupies a substantial portion of the pressing chamber expelling the not- oxidizing gas previously contained inside the latter, the not- oxidizing gas passes through the transit duct 36, under the reverse action of the fan 46 or by simple push, along a direction F2 opposite to previous direction FI, said not- oxidizing gas flowing towards the reservoir 42 that assumes a filling configuration shown by a continuous line.
  • the vacuum pump 222 works speeding up the above-mentioned progressing.
  • the vacuum pump 222 is stopped during the expansion and retraction of the membrane in order to avoid that the inert gas is accidentally removed from the operating volume previously defined.
  • the membrane valve 228 is closed when the vacuum pomp 222 is working, thus excluding the transit duct 36 from the cavity of the further container 19 and then preventing the inert gas from being removed, in undesirable manner, from the reservoir 42. So, only a small amount of inert gas, which is inside the further container 19 when vacuum pump 222 is working, is removed, said small amount being easily restorable in the apparatus.
