Description

La présente invention a pour objet un dispositif de pressoir à capacité variable, utilisable de préférence, mais non exclusivement, pour le pressurage du raisin destiné à l'élaboration du vin de champagne.The present invention relates to a press device with variable capacity, usable preferably, but not exclusively, for the pressing of grapes intended for the production of champagne wine.

Le pressurage du raisin destiné à l'élaboration du vin de champagne doit répondre à un cahier des charges très rigoureux.The pressing of grapes intended for the production of champagne wine must meet very rigorous specifications.

La pression doit être réalisée en sorte d'obtenir une extraction lente et progressive, on observe donc une progression lente du plateau de pressage, on réalise plusieurs presses, et pour chacune on marque des paliers successifs de maintien en pression.The pressure must be carried out in such a way as to obtain a slow and progressive extraction, we therefore observe a slow progression of the pressing plate, we carry out several presses, and for each we mark successive pressure maintenance levels.

De plus, on est tenu à une quantité de moût par rapport à la quantité de raisin pour chaque presse, on utilise à cet effet un débitmètre placé en aval du pressoir.In addition, we are required to have a quantity of must in relation to the quantity of grapes for each press; for this purpose we use a flow meter placed downstream of the press.

Ainsi, d'un marc de raisins de 4 000 kg, de manière simplifiée, on tire un jus préalable, issu d'autopressurage, qu'on élimine, puis un premier jus appelé cuvée représentant 20,5 hl obtenu par une première presse discontinue, puis de deux autres presses après émiettements ou retrousses, c'est-à-dire après avoir amené vers le centre du gâteau de marc sa partie périphérique qui a été moins exploitée lors du pressurage. Enfin, après une troisième retrousse, on presse pour obtenir 5 hl de jus appelé taille.Thus, from a grape marc of 4,000 kg, in a simplified manner, we extract a preliminary juice, resulting from self-pressing, which we eliminate, then a first juice called cuvée representing 20.5 hl obtained by a first discontinuous press , then two other presses after crumbling or rolling up, that is to say after having brought towards the center of the marc cake its peripheral part which was less exploited during pressing. Finally, after a third rolling, we press to obtain 5 hl of juice called size.

Les pressoirs sont dimensionnés en sorte de faciliter ces opérations, ils sont ainsi généralement conçus pour des multiples de 4000 kg, c'est-à-dire 4000, 8000 et 12000 kg. On notera qu'il existe également de plus petits pressoirs de 2000 kg, peu fréquents.The presses are sized to facilitate these operations, they are generally designed for multiples of 4000 kg, that is to say 4000, 8000 and 12000 kg. Note that there are also smaller presses of 2000 kg, which are not very common.

Cependant, il existe des vignes, souvent de petites surfaces, présentant des particularités d'âge, de sol et/ou d'exposition, qui sont susceptibles de permettre l'élaboration d'une cuvée parcellaire, plutôt que de servir dans un assemblage. Du fait de la faible quantité de raisins, inférieure aux quantités normalisées des pressoirs, ou n'atteignant pas le « compte rond » requis, il est difficile, voire impossible, d'en réaliser le pressurage et cela oblige à une utilisation en assemblage.However, there are vines, often small areas, with particularities of age, soil and/or exposure, which are likely to allow the development of a plot cuvée, rather than being used in a blend. Due to the small quantity of grapes, lower than the standardized quantities of the presses, or not reaching the required "round count", it is difficult, if not impossible, to carry out pressing and this requires use in blending.

On pourrait imaginer que la solution serait de charger un pressoir en dessous de sa charge nominale et de calculer, en fonction du poids de marc, la quantité de moût à extraire pour chaque presse, mais cela ne résoudrait pas le problème de la conduite du plateau mobile, de la réalisation des retrousses, c'est-à-dire l'obtention d'un émiettement optimal et d'une répartition homogène du marc.One could imagine that the solution would be to load a press below its nominal load and to calculate, based on the weight of the marc, the quantity of must to be extracted for each press, but this would not solve the problem of the control of the mobile platform, the production of the rolls, that is to say obtaining optimal crumbling and a homogeneous distribution of the grounds.

En effet, sous-charger un pressoir sans en modifier la taille se ferait au détriment de la qualité du jus obtenu du fait d'une trituration plus importante de la matière première.In fact, underloading a press without changing its size would be detrimental to the quality of the juice obtained due to greater crushing of the raw material.

La présente invention a pour but de remédier à cet inconvénient, en proposant un dispositif de pressoir à capacité variable, c'est-à-dire de taille adaptable à la quantité de matière à pressurer, permettant de limiter les triturations du marc, de réduire le temps de cycle de pressurage, tout en obtenant une excellente qualité de pressurage.The present invention aims to remedy this drawback, by proposing a press device with variable capacity, that is to say of size adaptable to the quantity of material to be pressed, making it possible to limit the crushing of the marc, to reduce pressing cycle time, while obtaining excellent pressing quality.

On notera que le dispositif de pressoir selon l'invention est de type horizontal c'est-à-dire comportant une cage destinée à recevoir la vendange, où un plateau circulaire ou rectangulaire mobile agit en translation horizontale pour venir écraser la vendange contre une paroi. Sur ces pressoirs, la retrousse du gâteau de marc peut être réalisée par rotation de la cage après recul du plateau, ce qui peut nécessiter une intervention manuelle.It will be noted that the press device according to the invention is of the horizontal type, that is to say comprising a cage intended to receive the harvest, where a circular or rectangular movable plate acts in horizontal translation to crush the harvest against a wall . On these presses, the pomace cake can be rolled up by rotating the cage after the plate has moved back, which may require manual intervention.

Parmi ces pressoirs horizontaux, on connaît également celui proposé par la présente Demanderesse dans le document EP 1 267 646 , qui avantageusement ne nécessite pas de retournement de la cage, et dont la particularité consiste en ce que le plateau mobile et la paroi fixe présentent une inclinaison par rapport à la verticale, en direction des moyens de déplacement dudit plateau mobile, en sorte qu'après retrait de ce dernier, au moins une portion du gâteau de marc se retrouve en porte-à-faux et que ladite portion soit susceptible de s'effondrer dans l'enceinte du pressoir en réalisant ainsi l'émiettement.Among these horizontal presses, we also know the one proposed by the present Applicant in the document EP 1 267 646 , which advantageously does not require the cage to be turned over, and whose particularity consists in that the movable plate and the fixed wall have an inclination relative to the vertical, in the direction of the means for moving said movable plate, so that after removal of the latter, at least one portion of the marc cake finds itself overhanging and said portion is likely to collapse within the enclosure of the press, thus causing crumbling.

On notera que l'on connaît, par le document FR2839007 , un dispositif de pressoir comprenant dans une cage horizontale deux plateaux mobiles en direction l'un de l'autre en sorte de pressurer la vendange qui y est intercalée.It will be noted that we know, from the document FR2839007 , a press device comprising in a horizontal cage two movable plates in the direction of one another so as to press the grapes interspersed therein.

Ce dispositif de pressoir comporte de plus un capteur de pression destiné à être disposé dans la vendange et relié par radio à la console de commande, ainsi que des capteurs de positions des plateaux. La nature de ces capteurs de positionnement n'est pas spécifiée, mais sachant que lesdits plateaux sont mus par une vis sans fin à pas inversés, le contrôle numérique de la rotation de cette dernière suffit à déterminer les positions des deux plateaux. Cela n'est toutefois applicable qu'à cette construction particulière.This press device also includes a pressure sensor intended to be placed in the harvest and connected by radio to the control console, as well as tray position sensors. The nature of these positioning sensors is not specified, but knowing that said plates are driven by an endless screw not inverted, the digital control of the rotation of the latter is sufficient to determine the positions of the two plates. This is, however, only applicable to this particular construction.

Le dispositif de pressoir à capacité variable selon l'invention est de type horizontal, il comporte une enceinte destinée à recevoir la vendange, où agit un plateau circulaire ou rectangulaire mobile en translation horizontale sous l'action d'un vérin, apte à venir écraser la vendange contre une paroi fixe, ledit plateau mobile et ladite paroi fixe, étant inclinés par rapport à la verticale en direction dudit vérin, en sorte qu'après retrait dudit plateau, au moins une portion du gâteau de marc se retrouve en porte-à-faux et que ladite portion soit susceptible de s'effondrer dans l'enceinte du pressoir en réalisant ainsi son émiettement, et il se caractérise en ce qu'il comporte de plus des moyens de détermination et de contrôle de la distance qui sépare ledit plateau mobile de ladite paroi fixe, lors du recul après une presse, ainsi que des moyens d'arrêt dudit recul lorsque la distance requise est atteinte, connectés auxdits moyens de détermination de la distance qui sépare ledit plateau mobile de ladite paroi fixe, lesdits moyens de détermination et de contrôle de la distance qui sépare le plateau mobile de la paroi fixe, consistant en un moyen de détermination et de contrôle de la distance parcourue par ledit plateau mobile.The variable capacity press device according to the invention is of the horizontal type, it comprises an enclosure intended to receive the grape harvest, where a circular or rectangular plate movable in horizontal translation acts under the action of a jack, capable of crushing the harvest against a fixed wall, said movable plate and said fixed wall, being inclined relative to the vertical in the direction of said cylinder, so that after removal of said plate, at least a portion of the marc cake is found in the door -false and that said portion is likely to collapse within the enclosure of the press thus causing its crumbling, and it is characterized in that it further comprises means for determining and controlling the distance which separates said plate mobile of said fixed wall, during the recoil after a press, as well as means for stopping said recoil when the required distance is reached, connected to said means for determining the distance which separates said movable plate from said fixed wall, said means for determination and control of the distance which separates the movable plate from the fixed wall, consisting of means for determining and controlling the distance traveled by said movable plate.

Ainsi, lors du recul, la distance qui sépare le plateau mobile de la paroi fixe, est celle juste nécessaire à l'effondrement du gâteau de marc, c'est-à-dire ni trop petite, ce qui générerait une retrousse incomplète, ni trop grande ce qui générerait un espace vide entre le gâteau de marc et le plateau mobile. Cette distance est bien entendue calculée en amont de l'opération de pressurage, à partir de la quantité de raisin à pressurer.Thus, during the retreat, the distance which separates the mobile plate from the fixed wall is that just necessary for the collapse of the marc cake, that is to say neither too small, which would generate an incomplete roll-up, nor too large which would generate an empty space between the marc cake and the moving plate. This distance is of course calculated before the pressing operation, based on the quantity of grapes to be pressed.

On peut ainsi faire varier la capacité de la cage en fonction de la quantité de matière première à traiter.We can thus vary the capacity of the cage depending on the quantity of raw material to be processed.

Selon autre caractéristique additionnelle du dispositif de pressoir selon l'invention, les moyens de détermination et de contrôle de la distance qui sépare le plateau mobile de la paroi fixe, consistent en au moins un télémètre.According to another additional characteristic of the press device according to the invention, the means for determining and controlling the distance which separates the movable plate from the fixed wall consist of at least one telemeter.

Les avantages et les caractéristiques du dispositif de pressoir selon l'invention, ressortiront plus clairement de la description qui suit et qui se rapporte au dessin annexé, lequel en représente un mode de réalisation non limitatif.The advantages and characteristics of the press device according to the invention will emerge more clearly from the description which follows and which relates to the appended drawing, which represents a non-limiting embodiment.

De manière non limitative, le dispositif de pressoir représenté est celui du document EP 1 267 646 , au nom de la présente Demanderesse.In a non-limiting manner, the press device shown is that of the document EP 1 267 646 , on behalf of the present Applicant.

En référence à la figure 1, on peut voir un dispositif de pressoir 1 selon l'invention, lequel comporte essentiellement une enceinte ou cage 10 délimitée par un fond constitué d'une maie filtrante 2, deux parois latérales 3 dont une seule est visible, une paroi transversale fixe 4, et un plateau mobile 5 apte à se déplacer entre les parois 3 en direction de la paroi transversale 4 sous l'action de moyens de poussée en l'occurrence un vérin hydraulique 50.In reference to the figure 1 , we can see a press device 1 according to the invention, which essentially comprises an enclosure or cage 10 delimited by a bottom consisting of a filter screen 2, two side walls 3 of which only one is visible, a fixed transverse wall 4, and a movable plate 5 capable of moving between the walls 3 towards the transverse wall 4 under the action of pushing means, in this case a hydraulic cylinder 50.

Le plateau mobile 5 présente du côté de l'enceinte 10 une paroi 51 divisée dans le sens vertical en deux parties, une partie inférieure 52 verticale et une partie supérieure 53 inclinée vers l'arrière, c'est-à-dire du côté du vérin 50. Dans ce mode de réalisation la partie supérieure inclinée 53 est d'une hauteur sensiblement double de celle de la paroi inférieure verticale 52.The mobile plate 5 has on the side of the enclosure 10 a wall 51 divided in the vertical direction into two parts, a lower part 52 vertical and an upper part 53 inclined towards the rear, that is to say on the side of the cylinder 50. In this embodiment the inclined upper part 53 is of a height substantially double that of the vertical lower wall 52.

La paroi transversale 4 présente un profil complémentaire de celui du plateau mobile 5, elle comporte ainsi une partie supérieure 40 parallèle à la partie 53, et, en regard de la partie inférieure 52, une partie inférieure 41 qui peut être de profil concave, c'est-à-dire de section transversale en arc de cercle, auquel la partie supérieure 40 est tangente.The transverse wall 4 has a profile complementary to that of the movable plate 5, it thus comprises an upper part 40 parallel to the part 53, and, in looking at the lower part 52, a lower part 41 which can be of concave profile, that is to say of cross section in an arc of a circle, to which the upper part 40 is tangent.

Sur les figures 1 et 2, sont représentées deux phases de pressurage d'une quantité nominale de vendange.On the figures 1 and 2 , two phases of pressing of a nominal quantity of harvest are represented.

Sur la figure 1, le vérin 50 est déployé et la vendange est pressée contre la paroi 4 par le plateau 5 pour former un gâteau de marc 7. Sur la figure 2, on peut voir qu'après le recul du plateau 5, le gâteau de marc 7 est effondré sur la maie 2, entre le plateau 5 et la paroi fixe 4, du fait de porte à faux de la partie supérieure du gâteau de marc 7 pressée par les parties 52 et 40 des parois respectivement 51 et 4.On the figure 1 , the cylinder 50 is deployed and the harvest is pressed against the wall 4 by the plate 5 to form a marc cake 7. On the figure 2 , we can see that after the retreat of the plate 5, the marc cake 7 is collapsed on the board 2, between the tray 5 and the fixed wall 4, due to the overhang of the upper part of the marc cake 7 pressed by parts 52 and 40 of walls 51 and 4 respectively.

En référence maintenant aux figures 3 et 4, on peut voir le même dispositif de pressoir 1, utilisé en capacité réduite, en l'occurrence de 25% sur la figure 3, sachant bien entendu que d'autres valeurs sont possibles.Referring now to figures 3 and 4 , we can see the same press device 1, used in reduced capacity, in this case 25% on the Figure 3 , knowing of course that other values are possible.

Sur la figure 3 le pressurage est réalisé de manière identique à celui représenté sur la figure 1, tandis que sur la figure 2 on peut voir que lors du recul du plateau mobile 5, ce recul est stoppé, en sorte de limiter l'espace dans lequel s'effondre le gâteau de marc 7, avec pour avantages, une moindre trituration du marc et une limitation du temps de cycle de pressurage puisque la course dans un sens et dans l'autre du vérin 50 est réduite.On the Figure 3 pressing is carried out in the same way as that shown on the figure 1 , while on the figure 2 we can see that when the moving plate 5 moves back, this movement is stopped, in order to limit the space in which the marc cake 7 collapses, with the advantages of less crushing of the marc and a limitation of the processing time. pressing cycle since the stroke in one direction and in the other of the cylinder 50 is reduced.

Pour atteindre ce résultat, le dispositif de pressoir 1 selon l'invention est équipé d'un moyen de détermination et de contrôle de la distance qui sépare le plateau mobile 5 de la paroi fixe 4.To achieve this result, the press device 1 according to the invention is equipped with a means for determining and controlling the distance which separates the mobile plate 5 from the fixed wall 4.

Dans ce mode de réalisation, le moyen de détermination et de contrôle de la distance qui sépare le plateau mobile 5 de la paroi fixe 4 consiste en un moyen de détermination de la distance parcourue par le plateau mobile 5 par rapport à la paroi fixe 4, et qui consiste en un capteur 8, de type télémètre optique, en l'occurrence, non limitativement, monté fixement sur bâti du dispositif de pressoir 1 en arrière du plateau mobile 5, et pointant son rayon 80 vers ce dernier.In this embodiment, the means for determining and controlling the distance which separates the movable plate 5 from the fixed wall 4 consists of a means for determining the distance traveled by the movable plate 5 relative to the fixed wall 4, and which consists of a sensor 8, of the optical telemeter type, in this case, non-limitatively, fixedly mounted on the frame of the press device 1 behind the mobile plate 5, and pointing its radius 80 towards the latter.

Du point de vue de la mise en oeuvre, selon la quantité de marc chargée dans le dispositif pressoir 1, on détermine la distance optimale de séparation du plateau 5 et de la paroi fixe 4 pour la retrousse, et on programme l'unité de commande du dispositif de pressoir 1 en sorte de stopper la rentrée du vérin 50 et donc le déplacement en recul du plateau 5 lorsque cette distance est atteinte.From the point of view of implementation, depending on the quantity of marc loaded in the press device 1, we determine the optimal separation distance of the plate 5 and the fixed wall 4 for the roll, and we program the control unit of press device 1 so as to stop the retraction of the cylinder 50 and therefore the backward movement of the plate 5 when this distance is reached.

En adaptant parfaitement la taille du volume de la cage du dispositif de pressoir 1 en fonction d'une quantité de raisin moindre, cela permet de garantir la même qualité du jus qu'en utilisant le dispositif de pressoir 1 dans des conditions de volume normal pour sa taille nominale.By perfectly adapting the size of the volume of the cage of the press device 1 according to a smaller quantity of grapes, this makes it possible to guarantee the same quality of juice as when using the press device 1 under normal volume conditions for its nominal size.

Le dispositif de pressoir 1 selon l'invention peut ainsi être utilisé avec une quantité de raisin inférieure à la valeur nominale du dispositif de pressoir 1, la réduction de la charge pouvant aller jusqu'à 50%.The press device 1 according to the invention can thus be used with a quantity of grapes lower than the nominal value of the press device 1, the reduction in the load being able to go up to 50%.
