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
On notera que l'on connaît, par le document
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.
