Description
L'invention a trait à l'égouttage de la vendange.The invention relates to the draining of the harvest.
On sait que l'égouttage dit "statique" se pratique en disposant la vendange dans une cuve pourvue en partie basse d'une grille, à travers laquelle on laisse le jus s'écouler naturellement. On obtient ainsi les premiers 30 à 50 % du liquide contenu dans la vendange.We know that so-called "static" drainage is practiced by placing the harvest in a tank provided in the lower part of a grid, through which the juice is allowed to flow naturally. The first 30 to 50% of the liquid contained in the harvest is thus obtained.
On pratique parfois ensuite un égouttage complémentaire dit "dynamique", où la vendange est mise en mouvement le long d'une grille, en général par une vis sans fin. Le jus total obtenu avec un égouttage statique suivi d'un égouttage dynamique, représente 70 à 80 % du liquide initialement contenu dans la vendange.Sometimes a complementary so-called "dynamic" drainage is sometimes practiced, where the harvest is set in motion along a grid, generally by a worm. The total juice obtained with static drainage followed by dynamic drainage represents 70 to 80% of the liquid initially contained in the harvest.
Si l'extraction du jus va au delà de ces 70 à 80 %, on ne réalise plus un égouttage, mais un pressurage demandant une action mécanique extrêmement vigoureuse sur la vendange, le jus obtenu étant dit "jus de presse", par opposition au jus obtenu par égouttage, dit "jus de goutte".If the extraction of the juice goes beyond these 70 to 80%, one no longer performs a draining, but a pressing requiring an extremely vigorous mechanical action on the harvest, the juice obtained being called "press juice", as opposed to juice obtained by draining, called "drop juice".
L'invention vise la production d'un jus de goutte de haute qualité avec un haut rendement en quantité, dans un égouttoir simple et commode à l'emploi.The invention relates to the production of a high quality drop juice with a high yield in quantity, in a simple drainer and convenient to use.
Elle propose à cet effet un égouttoir à vendange comportant une cuve fermée pourvue d'une grille d'égouttage ; caractérisé en ce qu'il comporte en outre une membrane disposée dans la cuve, adaptée à être mise sous pression pour forcer l'égouttage de la vendange à travers la grille ; ainsi que des moyens de transport disposés dans la cuve, pour évacuer hors de la cuve la vendange égouttée.To this end, it offers a harvest drainer comprising a closed tank provided with a drip grid; characterized in that it further comprises a membrane arranged in the tank, adapted to be pressurized to force the draining of the harvest through Grid ; as well as means of transport arranged in the tank, to evacuate out of the tank the drained harvest.
Lorsqu'on utilise l'égouttoir selon l'invention en laissant d'abord le jus s'écouler naturellement puis en forçant l'écoulement avec la membrane, le degré d'extraction final est comparable à celui obtenu avec un égouttage statique suivi d'un égouttage dynamique, c'est-à-dire à haut rendement.When the drainer according to the invention is used by first allowing the juice to flow naturally and then forcing the flow with the membrane, the final degree of extraction is comparable to that obtained with a static draining followed by dynamic drainage, that is to say high yield.
En réalisant un égouttage statique forcé plutôt qu'un égouttage dynamique, on fait toute l'extraction du jus sans triturer la vendange, et on obtient par conséquent un jus particulièrement limpide, c'est-à-dire de très haute qualité.By carrying out a forced static draining rather than a dynamic draining, all the juice is extracted without crushing the harvest, and one therefore obtains a particularly clear juice, that is to say of very high quality.
L'égouttoir selon l'invention est simple et commode à l'emploi, non seulement parce que le remplissage de la cuve et l'extraction du jus ne posent pas de difficultés, mais aussi parce qu'il comporte des moyens de transport intégrés, qu'il suffit d'actionner après la fin des opérations d'extraction du jus pour évacuer de la cuve la vendange égouttée, c'est-à-dire le marc de raisin.The drainer according to the invention is simple and convenient to use, not only because the filling of the tank and the extraction of the juice does not pose any difficulties, but also because it comprises integrated means of transport, that it is enough to activate after the end of the juice extraction operations to evacuate the drained grape harvest, that is to say the grape marc.
Selon des caractéristiques préférées de l'invention, les moyens de transport sont disposés contre une paroi sur laquelle se trouve la partie la plus basse du volume intérieur de la cuve.According to preferred features of the invention, the means of transport are arranged against a wall on which is the lowest part of the interior volume of the tank.
La vendange introduite dans la cuve va donc recouvrir les moyens de transport, qui se trouvent en partie basse, la paroi contre laquelle ils sont disposés procurant aux moyens de transport un appui les aidant à supporter, en outre du poids de la vendange, l'effort supplémentaire dû à la mise sous pression de la membrane. Celle-ci est par ailleurs isolée des moyens de transport par la vendange, de sorte qu'elle ne risque pas de se détériorer contre les arêtes des moyens de transport. Cette disposition des moyens de transport est ainsi avantageuse sur le plan de la fiabilité et de la longévité de l'égouttoir.The harvest introduced into the tank will therefore cover the means of transport, which are located in the lower part, the wall against which they are arranged providing the means of transport with a support helping them to bear, in addition to the weight of the harvest, the additional effort due to the pressurization of the membrane. It is also isolated from the means of transport by the harvest, so that it does not risk deteriorating against the edges of the means of transport. This arrangement of the means of transport is thus advantageous in terms of the reliability and the longevity of the drainer.
Selon d'autres caractéristiques préférées de l'invention, l'égouttoir comporte des moyens de récupération du jus de goutte qui communiquent avec le volume intérieur de la cuve au-dessus de la partie la plus basse dudit volume intérieur.According to other preferred features of the invention, the drainer comprises means for recovering the drop juice which communicate with the interior volume of the tank above the lowest part of said interior volume.
Le jus situé dans la cuve jusqu'à une certaine hauteur au-dessus de sa partie la plus basse, ne sera donc pas récupéré en tant que jus de goutte, ce qui est favorable à la qualité du jus de goutte produit, car on évite ainsi d'y inclure les bourbes que l'on trouve généralement à fond de cuve.The juice located in the tank up to a certain height above its lowest part, will therefore not be recovered as drop juice, which is favorable to the quality of the drop juice produced, since this avoids thus to include the muds which one generally finds at the bottom of the tank.
Selon d'autres caractéristiques préférées, favorables au caractère simple, fiable et économique de l'égouttoir :
- la cuve comporte un volume intérieur limité :
- par une paroi pleine sur laquelle se trouve la partie la plus basse du volume intérieur de la cuve ; et
- de chaque côté au-dessus de la paroi pleine, par une grille d'égouttage derrière laquelle se trouve une chambre de récupération du jus de goutte ;
- lesdits moyens de transport comportent au moins une vis sans fin ;
- lesdits moyens de transport comportent deux vis sans fin, séparées par une portion en saillie de ladite paroi ;
- ladite membrane forme une enveloppe fermée et est suspendue à une tige disposée longitudinalement en partie haute du volume intérieur de la cuve ;
- la membrane est alimentée en agent de pression par la tige, qui est creuse ;
- la membrane est élastique.
- the tank has a limited internal volume:
- by a solid wall on which is the lowest part of the interior volume of the tank; and
- on each side above the solid wall, by a drip grid behind which is a drop juice recovery chamber;
- said means of transport comprise at least one worm;
- said means of transport comprise two endless screws, separated by a projecting portion of said wall;
- said membrane forms a closed envelope and is suspended from a rod arranged longitudinally in the upper part of the interior volume of the tank;
- the membrane is supplied with pressure agent by the rod, which is hollow;
- the membrane is elastic.
L'invention propose également un procédé pour égoutter la vendange, caractérisé en ce qu'on utilise un égouttoir tel qu'exposé précédemment, avec les étapes suivantes :
- on dispose la vendange dans la cuve ;
- on laisse le jus s'écouler naturellement ;
- on met sous pression la membrane dans la cuve pour forcer l'écoulement du jus à travers la grille ;
- on met la membrane hors pression ; et
- on vidange la cuve en actionnant les moyens de transport.
- the harvest is placed in the tank;
- the juice is allowed to flow naturally;
- the membrane is pressurized in the tank to force the flow of the juice through the grid;
- the membrane is pressurized; and
- the tank is emptied by actuating the means of transport.
Selon des caractéristiques préférées dans certains types de vinification, après avoir disposé la vendange dans la cuve, on y laisse macérer la vendange avant de commencer l'extraction du jus.According to preferred characteristics in certain types of vinification, after having placed the harvest in the tank, the harvest is left to macerate there before starting the extraction of the juice.
On réalise ainsi une macération pélliculaire, qui permet d'extraire les arômes primaires contenus dans la peau du raisin, grâce au contact prolongé peau-liquide. On augmente encore ainsi, avec certains types de raisin, la qualité du jus de goutte produit.A skin maceration is thus carried out, which makes it possible to extract the primary aromas contained in the skin of the grape, thanks to the prolonged skin-liquid contact. This further increases the quality of the drop juice produced with certain types of grapes.
L'exposé de l'invention sera maintenant poursuivi par la description d'un exemple de réalisation, donnée ci-après à titre illustratif et non limitatif, en référence aux dessins très schématiques annexés, sur lesquels :
- la figure 1 est une élévation-coupe prise transversalement dans un égouttoir conforme à l'invention, au repos ;
- la figure 2 en est une élévation-coupe prise longitudinalement ; et
- les figures 3 et 4 sont des vues similaires à la figure 1, respectivement après remplissage de la cuve avec de la vendange, et après mise sous pression de la membrane.
- Figure 1 is a sectional elevation taken transversely in a drainer according to the invention, at rest;
- Figure 2 is a sectional elevation taken longitudinally; and
- Figures 3 and 4 are views similar to Figure 1, respectively after filling the tank with the harvest, and after pressurizing the membrane.
L'égouttoir à vendange illustré comporte une cuve fermée 1 de forme générale cylindrique à axe horizontal, reposant sur le sol par des pieds 2.The illustrated drainer comprises a closed
La cuve comporte une paroi latérale cylindrique 3 raccordée à chaque bout à une paroi transversale d'extrémité, respectivement 4A et 4B. Une paroi pleine 5 délimitant deux canaux longitudinaux séparés par une portion en saillie 6 est rapportée entre les parois 4A et 4B et au-dessus de la portion inférieure de la paroi 3, la portion la plus basse du volume intérieur de la cuve correspondant au fond de chacun de ces canaux. De chaque côté au-dessus de la paroi 5, sur une certaine hauteur, le volume intérieur de la cuve est également limité par une grille d'égouttage, respectivement 7A et 7B, rapportée entre les parois 4A et 4B et à peu près parallèle à la paroi 3. Au-dessus des grilles 7A et 7B, le volume intérieur de la cuve est directement limité par la paroi 3. L'espace situé entre la grille 7A ou 7B et la paroi 3 constitue une chambre de récupération du jus de goutte, respectivement 8A et 8B, dont le fond est relié à une tubulure 9A ou 9B de récupération du jus de goutte, munie d'un robinet de fermeture (non représenté). Une paroi 10A ou 10B isole la chambre 8A ou 8B de l'espace 11 situé entre les parois 3 et 5. Dans la paroi 4A, au bout de chaque canal délimité par la paroi 5, se trouve une trappe 12 de vidange du marc. En partie supérieure de la paroi 3 se trouvent deux ouvertures 13 d'admission de la vendange, reliées à une tubulure d'amenée 14. Une trappe 15 est disposée à peu près au centre de la paroi 4A, pour accéder à l'intérieur de la cuve, afin d'y installer ses équipements puis pour la maintenance.The tank has a
Une vis sans fin, respectivement 16A et 16B, est disposée contre la paroi 5, et plus précisément contre chacune de ses parties formant canal. Du côté de la paroi 4A, la vis sans fin est en regard de la trappe 12, tandis qu'elle se prolonge au-delà de la paroi 4B par un axe portant une poulie d'entraînement 17, relié par courroie à un moteur (non représenté) adapté à faire tourner la vis comme indiqué par une flèche.A worm, respectively 16A and 16B, is disposed against the
Une membrane 18, ici en matériau élastique, formant une enveloppe fermée, est suspendue à une tige 19 disposée longitudinalement en partie haute du volume intérieur de la cuve. La tige 19 est creuse (c'est un tube) et sert à l'alimentation de la membrane en agent de pression tel que de l'air comprimé. Ici (voir la figure 2), la tige 19 passe à l'intérieur de la membrane 18, et comporte cinq trous par lesquels l'agent de pression va dans la membrane ou en sort.A
On va maintenant décrire le fonctionnement de l'égouttoir illustré.We will now describe the operation of the illustrated drip tray.
A partir de la position de repos montrée sur la figure 1, avec les trappes 12 et 15 fermées, et les robinets des tubulures 9A et 9B fermés, on amène par les conduits 14 la vendange à traiter, qui rentre dans le volume intérieur de la cuve 1 par les ouvertures 13, jusqu'à remplir la cuve, opération à la fin de laquelle la membrane 18 flotte en quelque sorte sur la vendange (voir figure 3).From the rest position shown in FIG. 1, with the
Directement, ou après quelques heures de macération dans l'enceinte fermée constituée par le volume intérieur de la cuve, on commence la phase d'extraction du jus de goutte : on ouvre les robinets des tubulures 9A et 9B, le jus s'écoule naturellement, et au bout d'un certain temps le débit se réduit.Directly, or after a few hours of maceration in the closed enclosure formed by the interior volume of the tank, the phase of extraction of the drop juice is started: the taps of the
A ce moment, on envoie l'agent de pression dans la membrane 18, qui se gonfle, les raisins déjà égouttés naturellement sont comprimés (voir figure 4) ce qui les force à s'égoutter davantage, le jus recommence à couler puis au fur et à mesure le débit diminue jusqu'à devenir nul, la vendage compressée étanchant les grilles 7A et 7B. La phase d'extraction du jus est alors terminée.At this time, the pressure agent is sent into the
On met alors la membrane 18 hors pression, on ouvre les trappes 12 et on fait tourner les vis sans fin 16A et 16B pour évacuer hors de la cuve la vendange égouttée, c'est-à-dire le marc de raisin. La membrane reprend elle-même sa forme et sa position initiales, du fait de son élasticité et de son montage suspendu à la tige 19.The
On observera qu'ici, les ouvertures 13 d'alimentation en vendange sont de côté par rapport à la tige 19, ce qui permet à la membrane de rester au-dessus de la vendange (voir figure 3).It will be observed that here, the openings for supplying the harvest are sideways with respect to the
Ici, on a eu intérêt à utiliser deux vis sans fin, compte tenu du diamètre de la paroi cylindrique 3, mais dans des variantes de diamètres différents, on utilise une seule ou davantage que deux vis sans fin.Here, it has been advantageous to use two worms, taking into account the diameter of the
Les vis sans fin sont des moyens de transport particulièrement appropriés à l'égouttoir selon l'invention, tant sur le plan de la robustesse que de l'efficacité, mais dans certaines variantes, notamment à forme générale parallélépipédique, les vis sans fin peuvent être remplacées par des barres transversales entraînées par des chaînes sans fin, raclant le fond du volume intérieur de la cuve.Worms are particularly suitable means of transport for the drip tray according to the invention, both in terms of robustness and efficiency, but in certain variants, in particular of generally parallelepipedal shape, worms can be replaced by transverse bars driven by endless chains, scraping the bottom of the interior volume of the tank.
Plus généralement, l'invention ne se limite pas aux exemples décrits, mais englobe au contraire toutes les variantes que l'homme du métier pourra déterminer.More generally, the invention is not limited to the examples described, but on the contrary encompasses all the variants that a person skilled in the art can determine.
