Description

Machine alimentaire pour la préparation d'aliqot  Food machine for the preparation of aliqot
La présente invention se rapporte au domaine des machines de préparation alimentaire et concerne, en particulier, une machine de préparation de portions cuisinées instantanées. L'invention concerne plus particulièrement les machines destinées à un usage dans la restauration pour la préparation d'aliments entièrement prêt pour la dégustation, et concerne de manière encore plus particulière la restauration rapide. The present invention relates to the field of food preparation machines and concerns, in particular, a machine for preparing instant cooked portions. The invention relates more particularly to machines for use in catering for the preparation of food fully ready for tasting, and more particularly relates to fast food.
La conservation des aliments, notamment sous de forme de plats cuisinés, est un secteur sensible de l'industrie agroalimentaire. Si la plupart des aliments peuvent se conserver en vue de leur dégustation à un stade ultérieure, le stockage de certains aliments reste problématique. The preservation of food, especially in the form of ready meals, is a sensitive sector of the agri-food industry. While most foods can be stored for later tasting, the storage of certain foods remains problematic.
L'utilisation de conservateurs, le recourt à la surgélation, la sonication, l'ionisation, la lyophilisation etc. ne sont pas toujours compatibles avec les aliments à conserver, et modifient bien souvent les propriétés gustatives et/ou organoleptiques des aliments. C'est le cas des mélanges complexes, comme par exemple certains plats cuisinés, qui sont composés d'une pluralité d'ingrédients qu'il faut pouvoir conditionner, puis préparer au moment de la dégustation en restant le plus fidèle au goût et à la texture de la recette originale. The use of preservatives, the use of freezing, sonication, ionization, lyophilization etc. are not always compatible with the foods to be preserved, and often modify the taste and / or organoleptic properties of the food. This is the case of complex mixtures, such as certain cooked dishes, which are composed of a plurality of ingredients that must be able to be packaged, then prepare at the time of tasting, remaining the most faithful to the taste and taste. texture of the original recipe.
Dans le cadre des machines alimentaires qui distribuent des portions instantanément en fonction des besoins, telles que les distributeurs de crème glacée utilisés dans la restauration, la rhéologie des aliments est un facteur prépondérant qui doit être pris en considération. Cette rhéologie, qui est notamment conditionnée par la nature même de chaque ingrédient, est sensible à la température, ce qui rend compliqué la distribution de plats cuisinés préparés à partir d'un mélange de plusieurs ingrédients. L'aligot de pomme de terre, est un plat essentiellement préparé à partir de pomme de terre, de tome (fromage), d'eau et éventuellement de crème fraîche et/ou de lait. Si la conservation d'un tel aligot est connue de la demande FR 2 537 403 qui décrit un conditionnement sous forme de granules surgelées, la préparation automatisée d'un plat qui restitue fidèlement les propriétés gustatives, voire organoleptiques, de la recette d'origine est une tâche difficile. En outre, bien que des appareils de traitement automatisé de denrées alimentaires qui nécessitent un mélange, voire un malaxage, soient connus, comme par exemple les appareils décrits dans la demande EP 2 572 584, leur structure et leur mode de fonctionnement sont inadaptés à la préparation de plats cuisinés épais et collant, tel que l'aligot, qui les rendraient rapidement hors d'usage principalement à cause du colmatage des conduits et des organes de malaxage desdits distributeurs. In the context of food machines that distribute portions instantly as needed, such as ice cream vending machines used in catering, the rheology of food is a paramount consideration that must be taken into consideration. This rheology, which is particularly conditioned by the very nature of each ingredient, is sensitive to temperature, which makes it difficult to dispense prepared meals prepared from a mixture of several ingredients. The potato aligot, is a dish mainly prepared from potato, tome (cheese), water and possibly cream and / or milk. If the preservation of such an aligot is known from the application FR 2 537 403 which describes a packaging in the form of frozen granules, the automated preparation of a dish that faithfully restores the taste properties, or even organoleptic properties of the original recipe is a difficult task. In addition, although automated food processing devices that require mixing or kneading, are known, such as the devices described in EP 2 572 584, their structure and mode of operation are unsuited to the preparation of thick and sticky cooked dishes, such as aligot, which would quickly make them out of use mainly because of the clogging of the conduits and the kneading devices of said dispensers.
La présente invention vise à résoudre les inconvénients de l'art antérieur précité. A cet effet, la présente invention concerne un dispositif de malaxage, aussi désigné sous le vocable « malaxeur », pour la préparation d'un aligot, comprenant un boîtier de malaxage, contenant une enceinte qui débouche sur une entrée pour l'amenée de la matière à malaxer, et un organe de malaxage, caractérisé en ce que ledit organe de malaxage comprend au moins un galet qui est monté rotatif sur un arbre motorisé, une ou plusieurs surfaces d'appui du galet étant prévue pour coopérer par écrasement avec les surfaces de ladite enceinte du boîtier. L'arbre motorisé peut, par exemple, être mu par un moteur de type « brushless » - c'est-à-dire un moteur sans balais fonctionnant avec du courant continu - ou bien un moteur asynchrone, pouvant développer jusqu'à 1500kW (4P). Coopérer par écrasement signifie, dans le cadre de l'invention, que les surfaces viennent en appui l'une contre l'autre, ou qu'il existe un espace qui reste sensiblement constant entre deux surfaces destinées à coopérer pendant le mouvement de rotation des galets. Un tel espace entre les galets est idéalement de 0.2 à 0.4 mm. Une telle coopération entre le galet et la surface du boîtier permet un filage optimisé de l'aligot pour obtenir une consistance bien filante et homogène. The present invention aims to solve the disadvantages of the aforementioned prior art. For this purpose, the present invention relates to a kneading device, also referred to as a "kneader", for the preparation of an aligot, comprising a kneading box, containing an enclosure which opens onto an inlet for the feeding of the kneader. material to be kneaded, and a kneading device, characterized in that said kneading member comprises at least one roller which is rotatably mounted on a motorized shaft, one or more bearing surfaces of the roller being provided to cooperate by crushing with the surfaces. of said enclosure of the housing. The motorized shaft can, for example, be driven by a "brushless" motor - that is to say a brushless motor operating with direct current - or an asynchronous motor, which can develop up to 1500 kW ( 4P). In the context of the invention, cooperation by crushing means that the surfaces bear against one another, or that there is a space that remains substantially constant between two surfaces intended to cooperate during the rotational movement of the rollers. Such a space between the rollers is ideally 0.2 to 0.4 mm. Such cooperation between the roller and the surface of the housing allows optimized spinning of the aligot to obtain a well-spinning and homogeneous consistency.
De préférence, l'organe de malaxage comporte au moins deux galets, un premier galet et un deuxième galet. Une telle configuration permet une coopération entre au moins deux galets intégrés dans l'organe de malaxage est parfaitement compatible avec les produits alimentaires collants tels que les ingrédients entrant dans la préparation de l'aligot de pomme de terre. Les deux galets fonctionnent en synergie pour étirer la matière le plus possible. Ces galets fonctionnent comme des pales et sont d'avantage adapté à l'aligot en comparaison des pales montées sur les tiges, du type vis sans fin, qui équipent les malaxeurs-extrudeuses de l'art antérieur. Preferably, the mixing member comprises at least two rollers, a first roller and a second roller. Such a configuration allows a cooperation between at least two rollers integrated in the mixing member is perfectly compatible with sticky food products such as the ingredients used in the preparation of the potato aligot. The two rollers work in synergy to stretch the material as much as possible. These rollers work like blades and are more adapted to the aligot in comparison with the mounted blades on the rods, of the worm type, which equip the kneader-extruder of the prior art.
Les surfaces d'appui s'étendent sensiblement radialement à la surface des galets. Le nombre de surfaces d'appui de chaque galet de l'organe de malaxage n'est pas limité. Avantageusement, chaque galet comporte deux surfaces d'appui qui s'étendent sensiblement radialement à leur surface par rapport à leur axe de rotation, et les galets sont de préférence sensiblement de forme fusiforme en coupe transversale. La forme fusiforme permet de donner un profil aux galets de sorte à ce qu'ils soient continûment en contact avec la matière durant tous le malaxage. The bearing surfaces extend substantially radially to the surface of the rollers. The number of bearing surfaces of each roller of the mixing member is not limited. Advantageously, each roller comprises two bearing surfaces which extend substantially radially at their surface relative to their axis of rotation, and the rollers are preferably substantially fusiform in cross section. The fusiform shape provides a profile to the rollers so that they are continuously in contact with the material during all the mixing.
Chacune desdites surfaces d'appui est avantageusement au moins une portion d'hélicoïde. Une telle conformation hélicoïdale assure une coopération étroite des différentes surfaces sur la matière alimentaire à transformer, tout en permettant de chasser la matière malaxée vers une paroi du boîtier du dispositif de malaxage. Ainsi le profil des galets est étudié pour que toutes les surfaces de la matière à malaxer soient balayées par le mouvement de rotation. En outre, des essais effectués avec des galets à profil droit (non hélicoïdaux) ont établi que le malaxage n'est pas efficace, qu'il y a des phénomènes d'obstruction, que la matière n'est pas bien redirigée vers la sortie de l'enceinte du malaxeur, et que les produits pâteux ne s'évacuent pas. Each of said bearing surfaces is advantageously at least a portion of helicoid. Such a helical conformation ensures a close cooperation of the different surfaces on the food material to be transformed, while allowing to drive the kneaded material to a wall of the housing of the kneading device. Thus the profile of the rollers is designed so that all the surfaces of the material to be kneaded are swept by the rotational movement. In addition, tests carried out with straight-profile (non-helical) rollers have established that the mixing is not efficient, that there are obstruction phenomena, that the material is not well redirected towards the outlet of the mixer enclosure, and that the pasty products do not drain.
Avantageusement, les galets sont montés sur des arbres prévus pour être mis en rotation dans le même sens. Une telle configuration du système composé des galets et de leur axe assure un écoulement optimal de la matière malaxée. La rotation est par exemple effectuée dans le sens de rotation horaire des galets hélicoïdaux, de sorte à ramener le produit à malaxer sur un système de chauffage, par exemple sur la partie la plus chaude dudit système, assurant ainsi un chauffage plus rapide du produit. Advantageously, the rollers are mounted on shafts intended to be rotated in the same direction.

The refrigerating box 6 contains a hopper 7 of 10 liters filled with 4 kg of frozen aligot granules. The hopper 7 is connected to a screw dosing system 8 provided for the determination of a quantity of aligot granulate.
Le dispositif de malaxage 5 dont une vue détaillée est montrée à la figure 4 comporte un boîtier de malaxage 9. Le système de dosage par vis sans fin 8 est connecté sur la partie haute du boîtier de malaxage 9 du dispositif de malaxage 5 comme montré sur les figures 4 et 5. Sur le boîtier de malaxage 9 est également connecté un mécanisme d'hydratation du granulat équipé d'une électrovanne bistable qui permet la distribution d'une quantité d'eau prédéterminée. Le dispositif de malaxage 5 comprend un premier galet 1 1 a ainsi qu'un deuxième galet 1 1 b, le premier galet 1 1 a est monté sur un premier arbre 12a et le deuxième galet 1 1 b est monté sur un deuxième arbre 12b, et les deux galets sont tous les deux intégrés dans le boîtier de malaxage 9. Le premier galet 1 1 a et le deuxième galet 1 1 b ont une section transversale fusiforme et des surfaces d'appui hélicoïdales (voir figure 8). La surface externe des galets 1 1 a et 1 1 b est composé d'un matériau autonettoyant comportant un polymère anti-adhérant, par exemple du polytétrafluoroéthylène (PTFE). Dans un mode de réalisation préféré, les premiers et deuxième arbres 12a et 12b sont accouplés à un moteur 13 de 180 Watts visible sur la figure 5, laquelle représente le dispositif de malaxage 5 visible à la figure 4 sous un autre angle (vue de derrière par rapport à la figure 4). Sur les premier et deuxième arbres 12a et 12b sont fixés respectivement un premier engrenage 14a et un deuxième engrenage 14b, tous deux accouplés à un troisième engrenage 14c d'un arbre moteur 15, c'est-à-dire un arbre directement accouplé, voire relié, au rotor du moteur 13. Grâce à cette configuration montrée à la figure 5, la mise en marche du moteur 13 provoque la mise en rotation des premier et deuxième galets 1 1 a et 1 1 b dans le même sens de rotation. The kneading device 5, a detailed view of which is shown in FIG. 4, comprises a kneading box 9. The worm dosing system 8 is connected to the upper part of the kneading box 9 of the kneading device 5 as shown in FIG. Figures 4 and 5. On the mixing housing 9 is also connected a granulator hydration mechanism equipped with a bistable solenoid valve that allows the distribution of a predetermined amount of water. The kneading device 5 comprises a first roller 11a and a second roller 11b, the first roller 11a is mounted on a first shaft 12a and the second roller 11b is mounted on a second shaft 12b, and the two rollers are both integrated in the mixing box 9. The first roller 1 1 a and the second roller 1 1 b have a fusiform cross section and bearing surfaces helical (see Figure 8). The outer surface of the rollers 11a and 11b is composed of a self-cleaning material comprising a release polymer, for example polytetrafluoroethylene (PTFE). In a preferred embodiment, the first and second shafts 12a and 12b are coupled to a motor 180 Watts visible in Figure 5, which represents the kneading device 5 visible in Figure 4 from another angle (back view compared to Figure 4). On the first and second shafts 12a and 12b are respectively fixed a first gear 14a and a second gear 14b, both coupled to a third gear 14c of a drive shaft 15, that is to say a directly coupled shaft, or connected to the rotor of the motor 13. With this configuration shown in Figure 5, the start of the motor 13 causes the rotation of the first and second rollers 1 1a and 1 1b in the same direction of rotation.
Le dispositif de malaxage 5, suivant ce mode de réalisation détaillé, comporte un système de chauffage comportant deux résistances 16a et 16b de 200 Watts chacune et qui chauffent par effet joule la partie du boîtier de malaxage 9 placée en vis-à-vis du moteur 13, et qualifiée de zone arrière 17 du boîtier. Ce système de chauffage porte la préparation d'aligot à une température de 65 à 75 °C au bout de quelques minutes. Les surfaces internes du boîtier de malaxage 9 sont faites d'un matériau autonettoyant comportant un polymère anti-adhérant, par exemple du polytétrafluoroéthylène (PTFE), pour éviter que les produits alimentaires collants n'adhèrent aux parois. Le boîtier de malaxage 9 comporte sur sa face avant un couvercle 18 qui peut être fixé par vissage sur le reste du boîtier. Le couvercle 18 est escamotable, à la manière d'une trappe, pour évacuer le produit vers le bas comme montré sur la figure 10. Le fonctionnement du dispositif de malaxage 5 débute par la mise en mouvement des premier et deuxième galets 1 1 a et 1 1 b, qui sont mobile dans le même sens de rotation comme vu plus haut. Le moteur 13 est d'abord actionné de manière à mettre en mouvement les deux galets 1 1 a et 1 1 b dans le sens horaire, lorsqu'on les observe par la face avant du boîtier comme montré sur la figure 1 1 . La conformation hélicoïdale des galets 1 1 a et 1 1 b permet de plaquer les produits alimentaires, c'est-à-dire dans le cas présent le granulat d'aligot déversés depuis la trémie 7, sur la zone arrière 17 du boîtier de malaxage 9. Le profil des galets permet le balayage de toute la surface de l'aligot. La zone arrière 17 est chauffée par les deux résistances 16a et 16b, ce qui permet de chauffer le produit pendant le malaxage. Pendant cette étape le filant de l'aligot peut se former dans de bonnes conditions étant donné que le produit est continûment étiré et chauffé. The kneading device 5, according to this detailed embodiment, comprises a heating system comprising two resistors 16a and 16b of 200 Watts each and which heat effect Joule the part of the mixing box 9 placed vis-à-vis the engine 13, and described as a rear area 17 of the housing. This heating system carries the aligot preparation at a temperature of 65 to 75 ° C after a few minutes. The internal surfaces of the mixing box 9 are made of a self-cleaning material comprising a release polymer, for example polytetrafluoroethylene (PTFE), to prevent the sticky food products from adhering to the walls. The mixing box 9 has on its front face a cover 18 which can be fixed by screwing on the rest of the housing. The lid 18 is retractable, in the manner of a hatch, for discharging the product downwards as shown in FIG. 10. The operation of the kneading device 5 begins with the first and second rollers 1 1 a being set in motion and 1 1 b, which are movable in the same direction of rotation as seen above. The motor 13 is first actuated so as to move the two rollers 11a and 11b in a clockwise direction when viewed from the front of the housing as shown in FIG. The helical conformation of the rollers 11a and 11b makes it possible to press the food products, that is to say in this case the aligot granulate discharged from the hopper 7, onto the rear zone 17 of the mixing box. 9. The profile of the rollers allows the sweeping of the entire surface of the aligot. The rear zone 17 is heated by the two resistors 16a and 16b, which makes it possible to heat the product during mixing. During this step the spinning of the aligot can be formed under good conditions since the product is continuously stretched and heated.
Une fois le produit suffisamment chaud (65 à 75°C) et malaxé, il doit être déversé hors du malaxeur. A cette fin, la rotation du moteur 13 est actionnée dans l'autre sens, de sorte à provoquer la rotation des galets 1 1 a et 1 1 b dans le sens antihoraire comme montré sur la figure 12. La mise en rotation des galets 1 1 a et 1 1 b dans le sens antihoraire entraîne le déplacement de l'aligot vers la face avant du malaxeur, c'est-à-dire que l'aligot est plaqué contre le couvercle 18 du boîtier de malaxage 9. Le couvercle 18 est escamoté de manière synchrone avec la mise en marche dans le sens antihoraire pour permettre de déverser l'aligot prêt à la dégustation. Un levier de commande 19 actionne l'ouverture et la fermeture du couvercle 18. Once the product is sufficiently hot (65 to 75 ° C) and mixed, it must be poured out of the mixer. To this end, the rotation of the motor 13 is actuated in the other direction, so as to cause the rollers 11a and 11b to rotate in the counterclockwise direction as shown in FIG. 12. Rotation of the rollers 1 1 a and 1 1 b counterclockwise causes the aligot to move towards the front face of the kneader, that is to say that the aligot is pressed against the cover 18 of the kneading box 9. The lid 18 is retracted synchronously with the start in the counterclockwise direction to allow to pour the aligot ready for tasting. A control lever 19 actuates the opening and closing of the cover 18.
La figure 7 montre en éclaté la machine alimentaire 1 qui peut être facilement démontée, notamment grâce à la présence de deux boutons moletés 20a et 20b montés sur le couvercle 18. FIG. 7 shows an exploded view of the food machine 1 which can be easily dismantled, notably thanks to the presence of two knurled buttons 20a and 20b mounted on the cover 18.
L'utilisateur commande la mise en marche de la machine alimentaire 1 pour la préparation d'un aligot depuis le panneau de commande 21 , pour obtenir un aligot prêt à la dégustation à partir de granulats d'aligot surgelés. Les granulats sont d'abord hydratées, puis malaxées et chauffées, afin d'obtenir une préparation d'aligot qui est évacuée automatiquement en dehors de la machine alimentaire. The user controls the start of the food machine 1 for the preparation of an aligot from the control panel 21, to obtain an aligot ready for tasting from frozen aligot granules. The aggregates are first hydrated, then kneaded and heated, to obtain an aligot preparation that is automatically removed outside the food machine.
