Definitions

  • Presses have been known for a very long time, which are particularly suitable for extracting fruit juices and which include a capacity with perforated walls into which the materials to be pressed are introduced and compressed by means of an endless screw.
  • This general principle knows many variations, in particular in the shape of the hub of the worm and in the shape of the compression capacity itself. Whatever these variants, all presses of this type have the major drawback of causing crushing of the material to be pressed between the periphery of the central screw and the perforated walls of the container, because there is necessarily friction on the turns of the screw and on the perforated walls which act as a grater.
  • Document FR-A-82/03408 is also known, which describes a press having a first cylindrical part and a second frustoconical part, an axial helical screw having turns themselves same cylindrical on an equally cylindrical hub.
  • Document FR-A-83/05068 describes a press having a compression capacity having a first cylindrical part, a second frustoconical part connected to the first and a third also cylindrical part connected to the frustoconical part, the helical screw always having a cylindrical outline.
  • the helical screw is mounted movable axially while being rotatably mounted in the direction of a thrust on the material.
  • this screw meets a predetermined resistance, it is moved back to a starting position then, the rotation being stopped, the screw is pushed axially, without turning, on the material already pressed while we admit fresh material to press and the screw is removed by driving it in rotation in the opposite direction to the push so that it "unscrews" in the fresh material, then the cycle begins again.
  • This device provides an improvement over the previous presses but still has a significant drawback in that the pressure is exerted in the same direction as the introduction of the material, that is to say in a direction called “upstream-downstream” "and that, in addition, this pressure is predominant at the center of the capacity, the compulsory back pressure being obtained by means of a door placed across the end of the capacity opposite the entry of the material to be pressed.
  • the press which has a compression capacity in which there are two helical screws with inverted pitch on each of which is fixed a plate of the same section that the capacity and which plays the role of nut when the capacity is rotated, the screws being kept fixed, because the plates approach to press the material placed between them or move away to release it according to the direction in which the compression capacity is trained.
  • a press of this type also has a very poor yield since the duration of obtaining a "press" is three and a half hours and this time causes the oxidation of the tannins and all oxidizable substances including aromas, all resulting in a dark juice without taste or odor when the material to be compressed is a grape.
  • the present invention provides a solution constituting a considerable improvement since it provides for the presence of a conical shield which allows overpressure at the output of a pressing capacity, this capacity being made movable relative to a fixed piston. In this way, an assembly is produced which avoids all attacks against the mixture to be pressed and which has an excellent yield.
  • the present invention moreover, provides the means to improve the distribution of the working pressure in the capacity by using various alternative embodiments of the means which cause this pressure.
  • the subject of the invention is a method for separating by pressing liquid and solid fractions intimately associated into a heterogeneous mixture, as are, for example, the juices, pulps, pits, seeds, peduncles and plant elements of fruit such as grapes harvested, characterized in that one fills in a direction called "upstream-downstream", by a so-called entry end, a capacity with side walls traversed by fine passages, with heterogeneous mixture, then one interrupts the arrival of mixing, then one causes pressing by producing on the one hand a linear relative movement between the capacity and a non-workpiece rotating forming a piston located in front of the inlet end so that this part penetrates from upstream to downstream in the capacity and on the other hand an antagonistic retaining force, that is to say acting in the "downstream-upstream” direction ", coaxial with the capacity, at the end of the said outlet opposite to the previous one while providing an annular outlet space, also coaxial, for the solid fractions separated from the liquid fractions during pressing and thus
  • the invention also relates to a device for the implementation of this method, characterized in that it comprises on the one hand a capacity whose side walls are crossed by fine passages and which has two opposite open ends, the an "inlet” placed opposite a piston-forming part and provided an opening for the entry of mixture into the capacity, and on the other hand a shield associated with the other end called “outlet", the capacity-shield assembly being mounted movable relative to the part forming the piston so to press the material between the shield and the piston-forming part, the liquid fractions having to pass through the capacity by fine passages while the solid fractions must be evacuated around the shield.
  • Curve A shows this variation in a known device: 1 ⁇ pressure is immediately established at input 0 at a significant value then increases further and decreases regularly until output X where it is minimal.
  • Curve B shows the variation of this same pressure P1 according to the process according to the invention and it can be seen that at input 0 the pressure P1 is established at a relatively low value then increases regularly but slightly in thus remaining practically compliant up to the vicinity of the output X where it increases significantly to reach its maximum value.
  • Curve C shows the distribution of the pressure P2 in a device of known type and it can be seen that the pressure is maximum at the periphery while it is minimum in the central part x.
  • Curve D represents the distribution of the transverse pressure P2 with the method according to the invention and it can be seen that this curve D is exactly the opposite of curve C since the pressure P2 has minimum values at the periphery of the device and maximum values in the central part x.
  • FIG. 3 we have shown the effects, in a known device, of the pressure P1 shown diagrammatically by an arrow and it can be seen that this pressure P1 is exerted from the inlet to the outlet, that is to say say in the "upstream-downstream” direction and in the same direction as the entry of the mixture to be pressed, symbolized by two arrows F1.
  • Figure 4 is a diagram similar to that of Figure 3 but corresponding to the implementation of the method according to the invention. It can be seen that a retaining force F2 is created at the center of the device and at its exit and is directed in the direction opposite to that of the arrow F1 indicating the direction in which the mixture to be pressed is introduced into the device . This retaining force F2 comes from the presence of a central conical shield located at the exit of the device.
  • the retaining force F2 and the pressure P1 are indeed antagonistic, according to the method according to the invention, but the retaining force F2 is caused by the exit resistance of the cake.
  • this resistance comes from the presence of the shield, but it only acts against the pressure P1 indirectly, with the interposition of the cake.
  • This device includes a hopper 1 for loading a heterogeneous mixture and in the following description we will take as an example the grapes harvested to be pressed to give a juice as clear as possible providing, after treatment such as fermentation or distillation, a drink alcoholic, especially wine or Cognac.
  • the hopper 1 opens into a tank 2 in the shape of a bucket, that is to say with a bottom of circular section and with divergent planar walls.
  • this tank 2 extends an endless screw 3, the axis 4 of which is held by a bearing 5 and is connected to a motor for rotating 6.
  • the walls of the hopper 1 and of the tank 2 are perforated in order to allow the dripping juices collected to pass through an envelope 7 which surrounds the hopper 1 and the tank 2 and which has a discharge orifice 8.
  • the screw 3 At its end opposite to that which is close to the motor 6, the screw 3 comprises a second thread 9, just like the main thread and which ends in being diametrically opposite to it and both in a plane 10 perpendicular to axis 4, in order to form an obstacle to the return of mixture in the tank 2, from downstream to upstream, as will be explained below.
  • the diameter of the screw 3 is constant inside the tank 2 and decreases in line with a socket 11 whose interior is frustoconical and which thus has a circular central passage 12 of diameter less than the cross-section of the tank 2 and an annular part 11 co-planar with the plane 10, this assembly having to play the role of piston.
  • a solid central part could also be provided around which an annular passage would be provided for the transfer of the mixture by the screw 3.
  • the diameter of the capacity 14 increases in the "upstream-downstream” direction, that is to say in the direction of the entry of the mixture towards the exit of the solid fractions.
  • capacity 14 The walls of capacity 14 are perforated so that the liquid fractions separated from the solid fractions introduced and pressed into capacity 14 can pass therethrough.
  • the perforations of the capacity 14 are shown in the form of slots 15 resulting from intervals between solid parts 16 held together by external circular reinforcements 17 giving the assembly the rigidity of a structure complete.
  • a different structure can be used, in particular a grid made of perforated sheet metal with oblong openings of major axis parallel to the axis of the capacity 14, this grid being of the type known per se.
  • the grid must be held rigidly in the radial direction to resist the thrust of the pressed mixture and, for this purpose, reinforcements of the type of those shown here, 17 can be used.
  • the capacity 14 includes a cylindrical extension 18, the internal diameter of which corresponds to the external diameter of the sleeve 11 by providing for the interposition of joints and / or members facilitating the sliding of the extension 18 on the sleeve 11, or avoiding the effects of friction.
  • metal against metal these elements being generally designated by the reference 19.
  • beams 25 and 26 are fixed supporting profiles 27 and 28 extending inside the profiles 23 and 24.
  • Cylinders 30 and 31 are provided inside the profiles 27 and 28 in order to be able to move the capacity 14 relative to the co-planar parts 10 and 11 forming the piston.
  • the body 32 of the actuator 30 is fixed by an eyelet 33 and a flange 34 to the profile 23 while the rod 35 of the actuator 30 is connected by an eyelet 36 and a flange 37 to the profile 27.
  • the body 38 of the jack 31 is fixed by an eyelet 38 and a flange 40 to the profile 24 while the rod 41 of this jack 30 is fixed by an eyelet 42 and a flange 43 to the profile 28.
  • the cylinders 30 and 31 are of the double-acting type and therefore have fluid inlets 44-45 and 46-47 respectively controlled by solenoid valves, as is known per se, to cause the extraction of the rods 35 and 41 or their retraction.
  • the downstream end of the capacity 14 is entirely open and allows the establishment of a central conical shield 50 associated with radial coulters 51 and integral with an axial rod 52 slidably mounted in a guide 53.
  • the shield 50 is associated with an articulated diamond 54 of which two opposite vertices 55 and 56 are connected to a jack 57, respectively to the body 58 and to the rod 59 thereof, while the other two opposite vertices 60 and 61 are connected respectively at a fixed point and at the rod 52.
  • This jack 57 contains a pressurized fluid and acts as a shock absorber and it is advantageous to be able to adjust the passage section of an inlet 62 and an outlet 63, by any known means, to adjust the value of the resistance that the jack 57 opposes to the forces exerted on it by the conical shield 50, itself subjected to the thrust of the mixture.
  • the guide 53 is fixed to a crosspiece 64 joining two supports 65 and 66 integral with the capacity 14.
  • the jacks 30 and 31 were ordered so that the capacity 14 is in the position shown in FIG. 6 according to which the cylindrical part 18 completely covers the sleeve 11 so that the capacity 14 has a minimum volume.
  • the capacity 14 moves from upstream to downstream under the effect of the arrival of the mixture which pushes it, this "decline" in the capacity giving way to new arrivals of mixture. It should be noted that here there is only a simple push and not a compression since the capacity 14 moves effortlessly and since no force is developed against the arrival of the mixture.
  • the admission of pressurized fluid into the jacks 30 and 31 is controlled by the inputs 44 and 46, in order to move the capacity 14 in the direction of the arrows F5 (FIG. 7), towards its position of minimum volume, which has the effect of driving the shield 50 in the same direction by the supports 65 and 66 and by the cross-member 64, the cylindrical part 18 sliding on the cylindrical external part of the sleeve 11.
  • the jack 57 acts in the direction of bringing together the vertices 55 and 56 of the diamond 57, that is to say the spacing of the vertices 60 and 61, the rod 52 thus tending to push the shield 50 towards the interior of the capacity 14, in the downstream-upstream direction.
  • the shield 50 thus opposes the free exit of the mixture.
  • the displacement of the capacity 14 relative to the fixed socket 11 therefore causes the compression of the mixture between on the one hand the wall 13 and the co-planar plane 10 and on the other hand the central shield 50 with interposition of the dense cake already formed .
  • the wall 13 and the plane 10 constitute in a way a piston on which the mixture is pressed thanks to the action of the jacks 30 and 31, this pressure causing the exit of the liquid fractions by the slots 15 of the capacity 14 while the fractions solids accumulate in a dense cake downstream of the capacity 14.
  • the cake reaches a degree of dryness determined by the adjustment of the pressure in the jack 57, it is forced against the coulters 51 which fragment it into parts which exit the device according to arrows F6, through the annular passage.
  • the shield 50 undergoes two opposing forces: the pushing of the cake in the direction of the arrows F4 (FIG. 6) and the resistance of the jack 57.
  • the solid fractions of the mixture after extraction of the liquid fractions, have agglomerated into cake, it acts strongly on the shield 50 which can retreat against the jack 57, until a balance is established determined by the adjustment of the pressure in the jack 57.
  • the shield 50 moves back a little and, given its shape, correlatively enlarges the passage section offered at the outlet of the solid fractions, section determined by the width of the annular passage which remains between the outside of the cone 50 and the inside capacity 14.
  • the position of the shield 50 determines the section passage, the intensity of the retaining force and the rate of residual moisture in the cake, that is to say the value of the "pressed".
  • the compression of the mixture inside the capacity 14 is obtained by a simple linear movement in which the screw 3 does not intervene in any way by its rotary function since on the one hand it is stopped during the pressure phase and that on the other hand the mixture of the capacity 14 practically does not reach it thanks to the plane 10. It should be noted that with this embodiment, the pressure is not exerted from upstream to downstream but from downstream to upstream , according to arrows F5.
  • the endless screw 3 therefore only plays here the role of a material transport mechanism and could therefore be replaced by any other device if it turns out to be more practical than a worm.
  • the frustoconical shape of the capacity 14 the mixture moves from upstream to downstream, from the small base to the large, which eliminates the phenomenon of rasp and friction and which allows a better flow of the mixture as well as the total absence of trituration, the solid particles being oriented as shown in FIG. 4, as explained above.
  • the section of the tank 14 could be other than circular, for exam- D Ie oval.
  • the increase in pressure shown diagrammatically by curve B in FIG. 1 is obtained by the conical shield 50 and the jack 57 which is associated with it.
  • the shapes and dimensions of the shield 50 can be captured under different conditions of use. In all cases, the shield 50 being located in the axis of the device, it is in the center that the pressure P1 is the highest and it is indeed towards the periphery that it decreases since the outlet is annular shape.
  • the drying of the mixture is thus modulated according to the pressure which prevails in the jack 57 and, therefore, according to the retaining force of the shield 50.
  • a non-return valve can be provided as shown in FIG. 9.
  • the bush 11 and its front part 13 as well as its central passage 12 by which the mixture is introduced into the capacity 14 are shown diagrammatically in this figure.
  • the non-return valve is composed of a shutter 70 of diameter equivalent to that of passage 12 and provided with peripheral reliefs 71 by which it abuts against the front part 13 when it receives a pressure directed in the direction of the arrows F5, position in which the passage 12 is completely closed.
  • the shutter 70 is capped by a retaining piece 72 comprising arms 73 fixed to the part 13 and curved towards a common center 74 against which the shutter 70 is placed in abutment when it receives a pressure directed in the direction of the arrows F4, that is to say when the screw 3 is rotated and pushes the mixture through the central passage 12.
  • the conical shield 50 is removed and replaced by a central endless screw 80 of increasing diameter in the upstream-downstream direction and secured to a shaft 81 rotatably mounted in a retaining bearing 82 and connected to a setting mechanism. movement of any known type such as a gear motor 83.
  • the evacuation of the solid fractions can be modulated by varying the speed of the screw 80 to ensure a very precise adjustment and an excellent suitability of the device and of the mixture which is available in all circumstances.
  • the percentage of solid fractions relative to the liquid fractions discharged therefore depends on the speed of rotation of the screw 80.
  • longitudinal ribs 85 can be provided inside the capacity 14 to which the various components of the mixture are attached, thus preventing their entrainment by life 80.
  • the screw 80 has a variable pitch, in the direction of a decrease, from its upstream end towards its downstream base because along the screw 80 the volume of the mixture decreases further and it must be saved less space.

  • bearing 82 is integral with a crosspiece 64 and supports 65 and 66, as in the case of Figures 5 to 7 so that the capacity 14 and the screw 80 are made integral in translation. Their relative position can be adjusted according to the nature of the mixture to be treated. For this, two series of holes 68 are provided on the supports 65 and 66 and holes 69 on the crosspiece 64 in order to choose those which will be placed opposite for the passage of assembly bolts. This presetting is carried out according to the characteristics of the mixture to be treated. In the case of grapes, we may wish a different pre-setting for the first harvest and for those at the end of the campaign for example.
  • the screw 80 is only rotated when the mixture introduced into the capacity 14 is pressurized (the screw 3 being stopped) by deployment of the jacks 30 and 31. It is stopped when the jacks 30 and 31 are neutralized and that of the mixture is introduced into the capacity 14, the screw 3 then being in rotation.
  • shutter clovers (not shown) associated with the screw 80 to prevent the winding of materials around its axis and also acting as coulters.
  • the axis 4 of the screw 3 is hollow and receives freely, that is to say without friction and a fortiori without blocking, a shaft 100 carrying a screw thread 101 corresponding to the thread of the screw 3 and located in its extension.

In reality, the thread 101 may correspond to the end of the screw 3 as shown in FIG. 5.
  • the screw 3 has only one thread, while the shaft 100 carries a second thread 102 of the same pitch and the two threads 101 and 102 are shaped at their end as has already been described for the screw 3 opposite of Figure 5, that is to say that they end in a common plane 103 substantially perpendicular to the axis of the assembly.

  • the engine 105 When the mixture has to be compressed, the engine 105 is stopped only so that the shaft 100 is immobilized in rotation, unlike the axis 4 which continues to rotate, the mixture introduced into the hopper 1 continuing to be pushed from upstream to downstream. Simultaneously, the supply of the jack 106 is reversed so that its rod 107 is extracted and pushes the shaft 100.
  • the threads 101 and 102, by their co-planar parts 103 then act like a piston in the stationary capacity 14 and cause the pressing of the mixture as described above, the device being in the position shown in FIG. 12.
  • the cylinder 106 When the desired pressure is reached (and sensed, for example, by pressure gauges), the cylinder 106 is neutralized and the engine is restarted 105, still engaged with the groove 104 thanks to the length of the latter, but at a speed such that the shaft 100 rotates faster than the axis 4, and in the same direction, so that the threads 101 and 102 somehow "screw” into the mixture present behind them under the uninterrupted action of the thread 3, and rise axially until the shaft 100 has regained the position it occupies in FIG. 11.
  • the jack 106 is fed again to push the nets 101 e t 102 and the cycle begins again. It is noted that the drive of the shaft 100 by the motor 105 occurs regardless of the axial position of this shaft 100 and even during its sliding inside the axis 4.
