Description
La présente invention se rapporte au domaine des installations de distribution de boissons froides à l'aide d'une pompe, par exemple la distribution de bières sous pression, voire toutes autres boissons froides distribuées sous pression ou distribuées par pompage. L'invention porte plus particulièrement sur le circuit de distribution raccordant le groupe de refroidissement de la boisson et la colonne de tirage de ladite boisson.The present invention relates to the field of cold drink dispensing facilities using a pump, for example the distribution of pressurized beer, or even other cold drinks dispensed under pressure or pumped. The invention relates more particularly to the distribution circuit connecting the cooling unit of the beverage and the draw column of said beverage.
Les installations de distribution de boissons froides à l'aide d'une pompe sont bien connues et particulièrement utilisées pour le tirage de bières sous pression, d'autres boissons étant toutefois envisageables, notamment de l'eau, du cidre, des sodas, voire du vin. De telles installations sont notamment utilisées par les cafetiers et les restaurateurs.The cold drink dispensing facilities using a pump are well known and are particularly used for drafting beers under pressure, other drinks being possible, however, including water, cider, sodas or some wine. Such facilities are particularly used by coffee makers and restaurant owners.
Une telle installation comprend traditionnellement un groupe de refroidissement qui est déporté sous le bar ou dans un local annexe, au moins une colonne pour le tirage d'au moins une boisson qui est agencée sur le bar, et un circuit de distribution qui est raccordé en amont sur le groupe de refroidissement et en aval sur l'au moins une colonne.Such an installation traditionally comprises a cooling unit which is deported under the bar or in an additional room, at least one column for drawing at least one drink which is arranged on the bar, and a distribution circuit which is connected in upstream on the cooling group and downstream on the at least one column.
Selon une première réalisation connue du circuit de distribution, celui-ci comprend un manchon isolant en mousse, au moins un tuyau de distribution d'une boisson, dont l'extrémité amont est raccordée sur le groupe de refroidissement et l'extrémité aval est raccordée sur la colonne de tirage, le manchon isolant étant disposé autour dudit tuyau. Le circuit de distribution comprend également un tube de circulation d'eau froide qui est recourbé sur lui-même de sorte à présenter une partie montante et une partie descendante, lesdits parties s'étendant à l'intérieur du manchon à côté de l'au moins un tuyau de distribution, les deux extrémités du tube de circulation étant raccordées par le biais d'une ligne Python® sur le groupe de refroidissement. La présence du tube de circulation d'eau froide raccordé en boucle sur le groupe de refroidissement, à côté de l'au moins un tuyau de distribution, et celle du manchon isolant autour de l'au moins un tuyau de distribution et du tube de circulation en boucle, permettent de maintenir la boisson froide à une température proche de zéro degré, jusqu'à la colonne de tirage. L'extrémité aval du circuit de distribution est insérée dans la colonne et l'extrémité aval du tuyau de distribution est raccordée sur le robinet ou bec de ladite colonne. Cependant, la grosseur du manchon et l'encombrement de la portion recourbée du tube de circulation d'eau froide, ainsi que leurs rigidités, ne permettent pas auxdits éléments d'être insérés dans la colonne jusqu'au point de raccordement du tuyau de distribution sur le robinet. Il est donc nécessaire d'extraire la portion d'extrémité aval dudit tuyau de distribution hors du manchon pour venir la raccorder sur le robinet. Cette portion d'extrémité aval est par conséquent exposée au milieu ambiant dans la colonne, ce qui engendre le réchauffement de la boisson juste avant la sortie du robinet. Ce réchauffement peut être de quelques degrés, ce qui est considérable en particulier pour la bière qui doit idéalement être servie à trois degrés Celsius (3°C).According to a first known embodiment of the distribution circuit, this comprises an insulating foam sleeve, at least one beverage dispensing pipe, the upstream end of which is connected to the cooling unit and the downstream end is connected. on the draw column, the insulating sleeve being disposed around said pipe. The distribution circuit also comprises a cold water circulation tube which is bent over itself so as to have a rising portion and a descending portion, said portions extending inside the sleeve adjacent to the minus one distribution pipe, both ends of the circulation tube being connected via a Python® line to the cooling unit. The presence of the cold water circulation tube connected in a loop on the cooling unit, next to the at least one distribution pipe, and that of the insulating sleeve around the at least one distribution pipe and the cooling pipe. loop circulation, keep the cold drink at a temperature close to zero degrees, up to the draw column. The downstream end of the distribution circuit is inserted into the column and the downstream end of the distribution pipe is connected to the tap or spout of said column. However, the size of the sleeve and the size of the bent portion of the cold water circulation tube, as well as their rigidities, do not allow said elements to be inserted in the column to the connection point of the distribution pipe on the faucet. It is therefore necessary to extract the downstream end portion of said distribution pipe out of the sleeve to connect it to the tap. This downstream end portion is therefore exposed to the ambient environment in the column, which causes the beverage to warm up just before the exit of the tap. This warming can be a few degrees, which is considerable especially for beer which should ideally be served at three degrees Celsius (3 ° C).
Selon une seconde réalisation connue, le circuit de distribution comprend un manchon isolant dans lequel est inséré un premier tube de circulation d'eau froide. Un tuyau de distribution de la boisson est inséré dans le premier tube de circulation. Un connecteur spécifique est agencé à l'extrémité aval du premier tube de circulation et permet le raccordement de l'extrémité aval du tuyau de distribution sur le robinet de la colonne. En outre, un second tube de circulation d'eau froide est inséré dans le manchon isolant et est raccordé sur le connecteur, ledit connecteur étant configuré pour permettre la circulation de l'eau froide du second tube vers le premier tube. Les extrémités amont des deux tubes de circulation et du tuyau de distribution sont raccordées sur le groupe de refroidissement. L'eau froide circule en boucle dans le second tube de circulation puis dans le premier tube de circulation, ce qui permet de maintenir la boisson froide. Le connecteur évite le réchauffement de la boisson avant son tirage. Cette conception présente pour inconvénient d'être onéreuse et d'être adaptée à une colonne spécifique, ce qui empêche son utilisation avec tous les types de colonnes commercialisés et celles déjà dans le commerce. En outre l'encombrement du connecteur est important et la spécificité du connecteur nécessite, sur les colonnes à plusieurs robinets ou becs, l'utilisation d'autant de connecteurs que de robinets, ce qui implique la mise en oeuvre d'installations très encombrantes.According to a second known embodiment, the distribution circuit comprises an insulating sleeve in which is inserted a first cold water circulation tube. A drink dispensing pipe is inserted into the first circulation tube. A specific connector is arranged at the downstream end of the first circulation tube and allows the connection of the downstream end of the distribution pipe to the valve of the column. In addition, a second cold water circulation tube is inserted into the insulating sleeve and is connected to the connector, said connector being configured to allow the flow of cold water from the second tube to the first tube. The upstream ends of the two circulation tubes and the distribution pipe are connected to the cooling unit. Cold water circulates in a loop in the second circulation tube and then in the first circulation tube, which keeps the drink cold. The connector prevents the warming of the drink before it is drawn. This design has the disadvantage of being expensive and adapted to a specific column, which prevents its use with all types of commercially available columns and those already in commerce. In addition the size of the connector is important and the specificity of the connector requires the columns to several valves or nozzles, the use of as many connectors as valves, which involves the implementation of very cumbersome installations.

En outre, elle a pour objectif d'optimiser le maintien de la boisson froide durant sa circulation dans le circuit de distribution.The present invention aims to overcome the aforementioned drawbacks. In addition, it aims to optimize the maintenance of the cold drink during its circulation in the distribution circuit.
A cet effet, l'invention concerne un manchon de refroidissement comprenant une gaine interne, une gaine intermédiaire, une gaine externe, des moyens d'assemblage configurés entre lesdites gaines pour former une chambre circulaire interne et une chambre circulaire externe agencées plus ou moins de manière coaxiale entre elles. Ces gaines interne, intermédiaire et externe sont réalisées dans une matière étanche. En outre, le manchon de refroidissement comprend dans sa portion d'extrémité aval des moyens de communication agencés entre les chambres interne et externe. Par ailleurs, le manchon de refroidissement comprend dans sa portion d'extrémité amont un premier embout de raccordement configuré pour communiquer avec la chambre circulaire interne et un second embout de raccordement configuré pour communiquer avec la chambre circulaire externe. L'amont et l'aval des différents éléments constituant le manchon sont définis par le sens de circulation d'une boisson dans un tuyau de distribution qui est inséré dans le manchon de refroidissement. Selon cette conception, les premier et second embouts de raccordement peuvent être raccordés respectivement sur un circuit de départ d'eau froide depuis un groupe de refroidissement et sur un circuit de retour d'eau froide jusqu'audit groupe de refroidissement, de préférence par l'intermédiaire d'une ligne Python®, ce qui permet à l'eau froide sortant du groupe de refroidissement de circuler dans la chambre interne qui enveloppe au moins un tuyau de distribution d'une boisson, puis d'être transférée dans la chambre externe grâce aux moyens de communication, de sorte à être réinjectée dans le groupe de refroidissement, voire l'inverse selon le sens de circulation de l'eau froide dans le manchon de refroidissement. Cette conception permet de réduire l'encombrement du manchon, ce qui facilite son insertion dans la colonne de tirage et réduit la longueur de la portion d'extrémité aval du tuyau de distribution exposée au milieu ambiant dans la colonne, réduisant ainsi le réchauffement de la boisson avant son tirage.For this purpose, the invention relates to a cooling sleeve comprising an inner sheath, an intermediate sheath, an outer sheath, assembly means configured between said sheaths to form an inner circular chamber and an outer circular chamber arranged more or less of coaxially between them. These inner, intermediate and outer sheaths are made of a waterproof material. In addition, the cooling sleeve comprises in its downstream end portion of the communication means arranged between the inner and outer chambers. Furthermore, the cooling sleeve comprises in its upstream end portion a first connecting piece configured to communicate with the inner circular chamber and a second connecting piece configured to communicate with the outer circular chamber. The upstream and downstream of the various elements constituting the sleeve are defined by the direction of flow of a beverage in a distribution pipe which is inserted into the cooling sleeve. According to this design, the first and second connecting pieces can be connected respectively to a cold water leaving circuit from a cooling unit and to a cold water return circuit to said cooling unit, preferably by means of a cooling circuit. intermediate of a Python® line, which allows the cold water leaving the cooling unit to circulate in the inner chamber which envelopes at least one distribution pipe of a beverage, and then to be transferred to the outer chamber thanks to the communication means, so as to be fed back into the cooling unit, or even the reverse according to the direction of flow of cold water in the cooling sleeve. This design makes it possible to reduce the bulk of the sleeve, which facilitates its insertion into the draw column and reduces the length of the downstream end portion of the distribution pipe exposed to the ambient environment in the column, thus reducing the warming of the beverage before it is drawn.

De même, des seconds moyens d'assemblage étanches sont agencés entre les extrémités aval des gaines interne et externe uniquement, tandis que la gaine intermédiaire présente une longueur inférieure à celles des gaines interne et externe, ce qui permet de laisser l'extrémité aval de cette gaine intermédiaire libre et dégagée vis-à -vis des extrémités aval des gaines interne et externe. Ainsi, les gaines interne et intermédiaire constituent la chambre interne, et les gaines intermédiaire et externe constituent la chambre externe. En outre, le passage laissé entre l'extrémité aval de la gaine intermédiaire et les extrémités aval des gaines interne et externe, permet aux chambres interne et externe de communiquer entre elles. Par ailleurs, selon ce premier mode de réalisation, le premier embout de raccordement est agencé à l'extrémité amont de la gaine interne et le second embout de raccordement est agencé à l'extrémité amont de la gaine externe. Ce type de manchon permet notamment de constituer une première variante de manchon principal et un manchon terminal, comme cela sera expliqué dans la suite de la description.In a first embodiment of the cooling sleeve according to the invention, first sealed assembly means are arranged between the upstream ends of the inner, intermediate and outer sheaths. Similarly, second sealed assembly means are arranged between the downstream ends of the inner and outer sheaths only, while the intermediate sheath has a shorter length than the inner and outer sheaths, allowing the downstream end of this intermediate sheath free and clear vis-à -vis the downstream ends of the inner and outer sheaths. Thus, the inner and intermediate sheaths constitute the inner chamber, and the intermediate and outer sheaths constitute the outer chamber. In addition, the passage left between the downstream end of the intermediate sheath and the downstream ends of the inner and outer sheath, allows the inner and outer chambers to communicate with each other. Furthermore, according to this first embodiment, the first connection piece is arranged at the upstream end of the inner sheath and the second connection piece is arranged at the upstream end of the outer sheath. This type of sleeve allows in particular to constitute a first variant of main sleeve and a terminal sleeve, as will be explained in the following description.

Selon cette réalisation, le premier embout de raccordement est agencé à l'extrémité amont de la gaine interne et le second embout de raccordement est agencé à l'extrémité amont de la gaine externe. Par ailleurs, les moyens de communication comprennent un troisième embout de raccordement agencé à l'extrémité aval de la gaine interne, un quatrième embout de raccordement agencé à l'extrémité aval de la gaine externe et une pièce de circulation raccordée entre les troisième et quatrième embouts de raccordement. Ainsi, les gaines interne et intermédiaire constituent la chambre interne, et les gaines intermédiaire et externe constituent la chambre externe. En outre, la pièce de circulation raccordée entre les troisième et quatrième embouts permet aux chambres interne et externe de communiquer. Ce type de manchon permet notamment de constituer une seconde variante de manchon principal et un manchon intermédiaire, comme cela sera expliqué dans la suite de la description.In a second embodiment of the cooling sleeve according to the invention, first sealed assembly means are arranged between the upstream ends of the inner, intermediate and outer sheaths.

Furthermore, the communication means comprise a third connection piece arranged at the downstream end of the inner sheath, a fourth connection piece arranged at the downstream end of the outer sheath and a circulation piece connected between the third and fourth connection tips. Thus, the inner and intermediate sheaths constitute the inner chamber, and the intermediate and outer sheaths constitute the outer chamber. In addition, the circulation room connected between third and fourth end allows the internal and external chambers to communicate. This type of sleeve allows in particular to constitute a second variant of main sleeve and an intermediate sleeve, as will be explained in the following description.
Dans une réalisation préférentielle du manchon de refroidissement selon l'invention, celui-ci est configuré pour que la chambre interne assure un contact surfacique autour de l'au moins un tuyau de distribution qui est inséré dans ledit manchon. A cet effet, selon les deux variantes de réalisation précitée du manchon de refroidissement selon l'invention, voire pour toute autre variante, les gaines interne, intermédiaire et externe sont réalisées dans un matériau textile étanche et souple, notamment une matière plastique étanche et souple. Lorsque les chambres interne et externe sont emplies d'eau froide circulant dans celles-ci, la pression de l'eau et la souplesse du matériau permet à la gaine interne de se déformer et de venir épouser la forme du contour générée par l'au moins un tuyau de distribution inséré dans le manchon de refroidissement, ce qui permet de créer un contact surfacique entre la gaine interne et l'au moins un tuyau de distribution et, ainsi, d'optimiser le maintien de la fraicheur de la boisson circulant dans l'au moins un tuyau de distribution.In a preferred embodiment of the cooling sleeve according to the invention, it is configured so that the inner chamber provides a surface contact around the at least one distribution pipe which is inserted into said sleeve.
