Description

DISPOSITIF D’EVACUATION DE LA MOUSSE SUSCEPTIBLE DE SE FORMER LORS DE LA REALISATION D’UN JUS DE FRUITS OU DE DEVICE FOR EVACUATING FOAM LIKELY TO FORM WHEN MAKING FRUIT JUICE OR
LEGUMES VEGETABLES
DOMAINE DE L’INVENTION FIELD OF THE INVENTION
L’invention appartient au domaine de la production de jus par pressage de fruits ou de légumes. The invention belongs to the field of the production of juice by pressing fruit or vegetables.
Elle vise plus particulièrement un dispositif apte à évacuer la mousse susceptible de se former lors de l’opération de pressage. It relates more particularly to a device capable of evacuating the foam likely to form during the pressing operation.
ETAT ANTERIEUR DE LA TECHNIQUE PRIOR STATE OF THE TECHNIQUE
Le pressage de fruits ou de légumes, en vue de l’obtention d’un jus, peut s’accompagner d’un phénomène de moussage, inhérent au fruit en question, à la quantité d’eau qu’il contient, outre au procédé de pressage proprement dit. The pressing of fruits or vegetables, with a view to obtaining a juice, can be accompanied by a phenomenon of foaming, inherent to the fruit in question, to the quantity of water which it contains, in addition to the process actual pressing.
Si la mousse ainsi générée n’affecte pas le goût du jus en question, en revanche, elle peut impacter le volume réel de jus disponible pour le consommateur. Lorsque ce dernier s’approvisionne en jus considéré, par exemple en libre-service, il peut ainsi voir le flacon ou contenant de réception du jus typiquement rempli aux deux-tiers de jus et un tiers de mousse, et dès lors, considérer être volé. If the foam thus generated does not affect the taste of the juice in question, on the other hand, it can impact the actual volume of juice available to the consumer. When the latter obtains the juice in question, for example in self-service, he can thus see the bottle or container for receiving the juice typically filled two-thirds with juice and one-third with foam, and therefore consider being stolen .
Afin de s’affranchir de cette difficulté, il n’existe pas d’autre solution à ce jour que de laisser la mousse reposer, affectant de manière rédhibitoire la distribution de tels jus, notamment en libre-service, en raison du temps d’attente alors nécessaire. Alternativement, il est envisageable de mettre en œuvre un tamis à m ailles très fines, mais qui se bouche rapidement dans le cas de certains jus, tels que les jus de pomme. In order to overcome this difficulty, there is currently no other solution than to let the foam rest, which has a crippling effect on the distribution of such juices, in particular in self-service, due to the waiting then necessary. Alternatively, it is possible to implement a sieve with very fine meshes, but which clogs quickly in the case of certain juices, such as apple juice.
L’invention vise à proposer une solution simple pour évacuer cette mousse lors de la production de jus, se présentant sous la forme d’un dispositif susceptible en outre d’être intégré dans un contexte plus global d’appareils à production de jus. EXPOSE DE L’INVENTION The invention aims to provide a simple solution for evacuating this foam during the production of juice, in the form of a device that can also be integrated into a more global context of juice production devices. DISCLOSURE OF THE INVENTION
En premier lieu, l’invention vise un dispositif d’évacuation de la mousse susceptible de se former lors de la réalisation d’un jus de fruit ou de légume. Ce dispositif comprend : Firstly, the invention relates to a device for evacuating the foam likely to form during the production of a fruit or vegetable juice. This device includes:
■ un réceptacle du mélange de jus et de mousse en communication avec des moyens assurant le pressage du fruit ou du légume, ledit réceptacle étant pourvu d’un orifice positionné au niveau de sa base afin de permettre l’évacuation du jus ; ■ a receptacle for the mixture of juice and foam in communication with means ensuring the pressing of the fruit or vegetable, said receptacle being provided with an orifice positioned at its base in order to allow the evacuation of the juice;
■ un flotteur reçu dans ledit réceptacle, dont l’extrémité inférieure est apte à obturer l’orifice dont est muni ledit réceptacle, et dont la densité est inférieure à celle du jus considéré, ledit flotteur étant apte à coulisser au sein dudit réceptacle selon une direction verticale ; ■ a float received in said receptacle, the lower end of which is adapted to close the orifice with which said receptacle is provided, and the density of which is lower than that of the juice in question, said float being able to slide within said receptacle according to a vertical direction;
■ une zone de collecte et d’évacuation de la mousse communiquant avec le réceptacle au voisinage de sa mi-hauteur. ■ a foam collection and evacuation zone communicating with the receptacle in the vicinity of its mid-height.
En d’autres termes, l’invention consiste à collecter, au sein d’un seul et même réceptacle, le produit issu du pressage d’un jus de fruit ou de légume, et, en raison de la différence de densité entre le jus et la mousse, à engendrer l’obturation dudit réceptacle au moyen d’un flotteur si la mousse est trop abondante, de sorte qu’en raison du choix du matériau ou de la structure dudit flotteur, ladite mousse est insusceptible d’exercer une pression d’Archimède suffisante pour entraîner l’ascension dudit flotteur, et corollairement autoriser la vidange dudit réceptacle aussi longtemps qu’une quantité suffisante de jus soit présente dans le réceptacle, pour alors engendrer l’ascension dudit flotteur toujours sous l’effet de la poussée d’Archimède, et, corollairement, permettre alors l’évacuation du seul jus par l’orifice dont est muni ledit réceptacle. In other words, the invention consists in collecting, within a single and same receptacle, the product resulting from the pressing of a fruit or vegetable juice, and, because of the difference in density between the juice and the foam, to cause the closure of said receptacle by means of a float if the foam is too abundant, so that due to the choice of material or of the structure of said float, said foam is incapable of exerting pressure of Archimedes sufficient to cause the ascent of said float, and as a corollary to authorize the emptying of said receptacle as long as a sufficient quantity of juice is present in the receptacle, to then cause the ascent of said float still under the effect of the thrust of Archimedes, and, as a corollary, then allow the evacuation of the juice alone through the orifice with which said receptacle is provided.
Selon l’invention, le dispositif comprend également un lest susceptible de prendre appui sur le flotteur, afin de limiter sa course ascensionnelle sous l’action de la pression d’Archimède exercée par le jus. Ce lest a vocation à faire en quelque sorte fonction de robinet, permettant de libérer la quantité de jus ad hoc, alors stocké dans le réceptacle. According to the invention, the device also comprises a ballast capable of resting on the float, in order to limit its upward travel under the action of the Archimedean pressure exerted by the juice. This ballast is intended to act as a sort of valve, allowing the ad hoc quantity of juice to be released, then stored in the receptacle.
Selon l’invention, le dispositif comprend également un levier articulé sur le dispositif en question, et auquel est solidarisé le lest précité. Ce faisant, l’utilisateur peut attendre qu’une quantité de jus soit suffisante dans le réceptacle, ayant entraîné une ascension partielle dudit flotteur mais bloqué par le lest pour libérer alors l’ouverture effective du réceptacle en actionnant ledit levier. La quantité de jus est dans ce cas suffisante pour remplir un contenant ou un flacon de volume déterminé. According to the invention, the device also comprises a lever articulated on the device in question, and to which the aforementioned ballast is secured. In doing so, the user can wait for a sufficient quantity of juice to be in the receptacle, having caused the said float to rise partially but blocked by the ballast to then release the effective opening of the receptacle by actuating said lever. The quantity of juice is in this case sufficient to fill a container or a bottle of determined volume.
Selon une forme de réalisation de l’invention, le réceptacle et le flotteur présentent une symétrie de rotation. Avantageusement cette symétrie de rotation est même une symétrie de révolution, le réceptacle présentant un fond conique et le flotteur présentant également un fond conique dont la pointe vient obturer l’orifice ménagé à l’extrémité inférieure du fond conique du réceptacle. According to one embodiment of the invention, the receptacle and the float have rotational symmetry. Advantageously, this rotational symmetry is even a rotational symmetry, the receptacle having a conical bottom and the float also having a conical bottom whose tip closes off the orifice made at the lower end of the conical bottom of the receptacle.
Avantageusement, le flotteur est constitué de tout matériau dont la densité est adaptée par rapport à celle du jus en question, et typiquement en polyéthylène haute densité ; ce flotteur peut même être avantageusement creux, facilitant sa réalisation et limitant en outre son poids. Advantageously, the float is made of any material whose density is adapted to that of the juice in question, and typically of high density polyethylene; this float can even be advantageously hollow, facilitating its production and further limiting its weight.
L’invention concerne également un dispositif de pressage et d’obtention d’un jus de fruit ou de légume. Ce dispositif comporte notamment un organe de pressage du fruit ou du légume, propre à générer un jus, notamment accompagné de mousse, communiquant avec le dispositif d’évacuation de la mousse précité. The invention also relates to a device for pressing and obtaining a fruit or vegetable juice. This device comprises in particular a member for pressing the fruit or vegetable, capable of generating a juice, in particular accompanied by foam, communicating with the device for discharging the aforementioned foam.

La figure 3 est une représentation schématique en section de ce dispositif. DESCRIPTION DETAILLEE DE L’INVENTION Figure 3 is a schematic sectional representation of this device. DETAILED DESCRIPTION OF THE INVENTION
Ainsi qu’on l’a représenté en relation avec la figure 1, on a illustré en premier lieu un ensemble (1) de pressage de fruits ou de légumes en question. En l’espèce, un tel ensemble de pressage a par exemple été décrit en relation avec le document FR 3 093 416, du Demandeur. Il comporte fondamentalement : As has been represented in relation to FIG. 1, a set (1) for pressing the fruits or vegetables in question has firstly been illustrated. In the present case, such a pressing assembly has for example been described in relation to document FR 3 093 416, of the Applicant. It basically includes:
■ un réceptacle (2) des fruits ou des légumes ; ■ a receptacle (2) for fruit or vegetables;
■ un organe de déstructuration (3) des fruits ou des légumes ; ■ a destructuring member (3) of fruits or vegetables;
■ un organe de pressage (4) destiné à écraser les éléments de fruits ou de légumes après déstructuration afin d’extraire le jus ; et ■ a pressing member (4) intended to crush the fruit or vegetable elements after destructuring in order to extract the juice; and
■ un organe de filtration (5). ■ a filtration unit (5).
L’organe de filtration est destiné à séparer le jus des éléments provenant de la déstructuration du fruit ou du légume, et notamment la pulpe. The filtration unit is intended to separate the juice from the elements resulting from the breakdown of the fruit or vegetable, and in particular the pulp.
L’organe de déstructuration (3) est, dans l’exemple décrit, solidaire de l’organe de filtration (5), et est typiquement constitué d’un tambour unique à symétrie de révolution. Ce tambour est monté rotatif autour de l’organe de pressage (4), constitué d’un noyau central statique, présentant une symétrie de révolution dont l’axe de révolution est confondu avec l’axe de rotation du tambour constitutif de l’organe de déstructuration et de filtration. Un moteur électrique, dont seul l’axe de transmission (6) a été représenté, assure la rotation du tambourThe destructuring member (3) is, in the example described, integral with the filtration member (5), and typically consists of a single drum with symmetry of revolution. This drum is rotatably mounted around the pressing member (4), consisting of a static central core, having a symmetry of revolution whose axis of revolution coincides with the axis of rotation of the drum constituting the member destructuring and filtration. An electric motor, of which only the transmission shaft (6) has been shown, ensures the rotation of the drum
(3, 5). (3, 5).
Le jus et la mousse résultant de la filtration sont collectés au niveau d’un orifice (7) traversant le bol de réception (8), et sont acheminés au niveau d’un réceptacle voisin (9) situé légèrement en contrebas, de telle sorte à pouvoir se déverser en son sein. Dans l’exemple de réalisation décrit, ce réceptacle (9) de réception du produit résultant du pressage du fruit ou du légume et typiquement constitué d’un mélange de jus et de mousse, présente une symétrie de révolution. Il est constitué d’un cylindre se terminant par un fond conique (10). La pointe du cône est pourvue d’un orifice traversant (11), destiné à permettre la mise en communication dudit réceptacle avec un récipient, type flacon, bouteille ou autres (12). Selon l’invention, ce réceptacle (9) reçoit un flotteur (13), également de symétrie de révolution, et d’axe de révolution coïncidant ou confondu avec l’axe de révolution du réceptacle (9). Ses dimensions sont telles que ledit flotteur (13) est à même de coulisser verticalement au sein du réceptacle (9), tout en étant sensiblement guidé au sein de ce dernier. Il existe donc un jeu suffisamment réduit mais à la fois suffisant pour permettre le libre coulissement du flotteur ainsi constitué au sein du réceptacle, et le ruissellement du jus dans le réceptacle (9). The juice and the foam resulting from the filtration are collected at the level of an orifice (7) passing through the receiving bowl (8), and are routed to the level of a neighboring receptacle (9) located slightly below, so that to be able to flow into it. In the embodiment described, this receptacle (9) for receiving the product resulting from the pressing of the fruit or vegetable and typically consisting of a mixture of juice and foam, has rotational symmetry. It consists of a cylinder ending in a conical bottom (10). The tip of the cone is provided with a through orifice (11), intended to allow said receptacle to be placed in communication with a receptacle, of the flask, bottle or other type (12). According to the invention, this receptacle (9) receives a float (13), also of symmetry of revolution, and of axis of revolution coinciding or coinciding with the axis of revolution of the receptacle (9). Its dimensions are such that said float (13) is able to slide vertically within the receptacle (9), while being substantially guided within the latter. There is therefore a sufficiently small game but at the same time sufficient to allow the free sliding of the float thus constituted within the receptacle, and the runoff of the juice into the receptacle (9).
Ce flotteur (13), également cylindrique, présente une extrémité inférieure conique (14), ce cône ayant vocation à obturer l’orifice traversant (11) dont est muni le réceptacle (9) sous l’action de son propre poids. This float (13), also cylindrical, has a conical lower end (14), this cone being intended to close the through hole (11) with which the receptacle (9) is provided under the action of its own weight.
Le matériau constitutif du flotteur (13) est choisi de telle sorte que sa densité soit inférieure à celle du jus, afin qu’il puisse se mouvoir verticalement, et en l’espèce en direction du haut, sous l’action de la pression d’Archimède exercée par le jus lorsque ce dernier est en quantité suffisante au sein du réceptacle (9). The constituent material of the float (13) is chosen so that its density is lower than that of the juice, so that it can move vertically, and in this case upwards, under the action of the pressure of Archimedes exerted by the juice when the latter is in sufficient quantity within the receptacle (9).
En revanche, le flotteur (9) est d’une densité suffisamment importante pour que la mousse résultant du produit résultant du pressage du fruit ou du légume, ne puisse engendrer une telle pression d’Archimède suffisante susceptible d’engendrer son ascension verticale en seule présence de la mousse, ou en cas de volume insuffisant de jus au fond dudit réceptacle (9). On the other hand, the float (9) is of a sufficiently high density so that the foam resulting from the product resulting from the pressing of the fruit or vegetable cannot generate such a sufficient Archimedean pressure capable of generating its vertical ascent in one presence of foam, or in case of insufficient volume of juice at the bottom of said receptacle (9).
En d’autres termes, s’il n’est déversé dans le réceptacle que de la mousse, la pression d’Archimède exercée par cette dernière est insuffisante pour engendrer l’ascension du flotteur (13), et donc ce dernier maintient l’obturation du réceptacle (9). In other words, if only foam is poured into the receptacle, the Archimedean pressure exerted by the latter is insufficient to cause the float (13) to rise, and therefore the latter maintains the closure of the receptacle (9).
Si, en revanche, un mélange de mousse et de jus est versé concomitamment dans le réceptacle (9), la quantité de jus doit atteindre un certain niveau au sein de ce dernier pour engendrer l’ascension du flotteur (13). If, on the other hand, a mixture of foam and juice is poured simultaneously into the receptacle (9), the quantity of juice must reach a certain level within the latter to cause the float (13) to rise.
On conçoit dans ces conditions que l’ascension du flotteur (13), libérant l’orifice inférieur (11) du réceptacle (9), ne permet l’évacuation que du seul jus, à l’exclusion de la mousse. Cette dernière est avantageusement évacuée au niveau d’une zone d’évacuation latérale (15) communiquant (16) avec le réceptacle (9) sensiblement au niveau de la mi-hauteur de ce dernier. La mousse alors recueillie est évacuée dans un contenant prévue à cet effet, ou est directement déversée à l’égout. It is understood under these conditions that the rise of the float (13), releasing the lower orifice (11) of the receptacle (9), only allows the evacuation of the juice alone, excluding the foam. The latter is advantageously evacuated at the level of a lateral evacuation zone (15) communicating (16) with the receptacle (9) substantially at the level of the mid-height of the latter. The foam then collected is evacuated in a container provided for this purpose, or is directly discharged into the sewer.
Typiquement, le flotteur (13) est réalisé en un matériau à propriétés alimentaires et par exemple en polyéthylène haute densité. Il est avantageusement creux, à tout le moins dans sa partie supérieure, et dans ce cas ouvert à sa partie supérieure. Typically, the float (13) is made of a material with food properties and for example of high density polyethylene. It is advantageously hollow, at least in its upper part, and in this case open in its upper part.
Idéalement, le dispositif comprend également un lest (17), destiné à agir sur le flotteur (13) au niveau de son extrémité supérieure (18). Ce lest (17) a vocation à s’opposer à la course ascensionnelle du flotteur, nonobstant la présence de jus. Ce lest est libéré au moyen d’un levier (19) reposant en (24) sur la paroi du réceptacle (9). Ainsi, dans l’exemple de réalisation illustré, lorsque l’utilisateur appuie sur l’extrémité libre du levier (19), il engendre le relevage du lest (17), et corollairement, la libération du flotteur (13), et donc l’écoulement possible du jus par l’orifice (11). Ideally, the device also comprises a ballast (17), intended to act on the float (13) at its upper end (18). This ballast (17) is intended to oppose the upward movement of the float, notwithstanding the presence of juice. This ballast is released by means of a lever (19) resting at (24) on the wall of the receptacle (9). Thus, in the illustrated embodiment, when the user presses on the free end of the lever (19), it causes the lifting of the ballast (17), and as a corollary, the release of the float (13), and therefore the possible flow of the juice through the orifice (11).
Selon un mode spécifique de réalisation de l’invention, l’autre extrémité (25) du levier (19) reçoit en (20) l’extrémité d’une tige (21) mobile en translation verticale. Cette tige, qui dans l’exemple décrit est coudée, intègre dans sa partie horizontale (26) un aimant permanentAccording to a specific embodiment of the invention, the other end (25) of the lever (19) receives at (20) the end of a rod (21) movable in vertical translation. This rod, which in the example described is bent, incorporates in its horizontal part (26) a permanent magnet
(22). La présence de l’aimant à une hauteur déterminée, est détectée au moyen d’un capteur(22). The presence of the magnet at a determined height is detected by means of a sensor
(23), positionné dans la structure générale du dispositif. Ce capteur (23), lorsqu’il détecter la présence de l’aimant (22) à son niveau, et en l’espèce tel que représenté sur le figure 2, engendre alors l’opération de pressage des fruits ou des légumes par le dispositif plus global, illustré sur la figure 1. (23), positioned in the general structure of the device. This sensor (23), when it detects the presence of the magnet (22) at its level, and in this case as shown in Figure 2, then generates the operation of pressing the fruits or vegetables by the more global device, illustrated in figure 1.
On conçoit tout l’intérêt du dispositif de l’invention qui permet de manière simple et efficace de limiter, voire d’annuler, tout versement de mousse au niveau du flacon recevant le jus. We can see the whole advantage of the device of the invention, which makes it possible in a simple and effective way to limit, or even cancel, any pouring of foam at the level of the bottle receiving the juice.
