Description

L'invention concerne un mélangeur, notamment un pétrin, muni de plusieurs outils de mélange ainsi qu'une installation comprenant un tel mélangeur. Des exemples de tels mélangeurs sont exposés dans les documents FR-A-322914 , US-A-3169493 , DE-B-1160801 , DE-A-56989 et DE-B-1018846 .The invention relates to a mixer, particularly a mixer, provided with several mixing tools and an installation comprising such a mixer. Examples of such mixers are shown in the documents FR-A-322 914 , US Patent 3169493 , DE-B-1160801 , DE-56989 and DE-B-1018846 .

De tels mélangeurs peuvent être utilisés dans tous les domaines du mélange industriel comme par exemple la réalisation de pâte pour la boulangerie ou le mélange de poudres, de viandes, de salades.Such mixers can be used in all areas of industrial mixing such as the production of dough for the bakery or the mixture of powders, meats, salads.

Pour assurer un bon pétrissage de la pâte alimentaire, notamment de boulangerie, les pétrins doivent être agencés pour faire subir à la pâte une succession de cisaillements et d'étirements à l'intérieur de la cuve.To ensure a good kneading of the pasta, especially bakery, the kneaders must be arranged to subject the dough a succession of shears and stretches inside the tank.

Dans l'art antérieur, on connaît trois types de mélangeurs destinés à ces applications :

  • les pétrins à axe oblique, comportant une cuve de révolution tournante et des outils de mélange rotatifs (dont l'axe est oblique) plongeant dans la cuve ;
  • les pétrins à spirales, comportant également une cuve de révolution tournante et des outils de mélange rotatifs plongeant dans la cuve ;
  • les batteurs, comportant une cuve fixe et des outils de mélange rotatifs plongeant dans la cuve et dont l'axe de rotation décrit un cercle à l'intérieur de la cuve.
In the prior art, three types of mixers are known for these applications:
  • the oblique-axis kneaders, comprising a tank of rotating revolution and rotary mixing tools (whose axis is oblique) immersed in the tank;
  • spiral kneaders, also comprising a tank of rotating revolution and rotary mixing tools immersed in the tank;
  • drummers, comprising a fixed bowl and rotating mixing tools immersed in the tank and whose axis of rotation describes a circle inside the tank.

Ces mélangeurs de l'art antérieur présentent principalement des inconvénients liés à la présence d'outils plongeant par le dessus la cuve, rendant l'accès à celle-ci difficile lors du chargement et du déchargement de la matière à mélanger.These mixers of the prior art have mainly disadvantages related to the presence of tools diving by the above the tank, making access to it difficult when loading and unloading the material to be mixed.

Certains de ces mélangeurs disposent de têtes porteuses d'outils relevables qui dégagent l'outil de la cuve mais n'offrent pas un accès complètement libre.Some of these mixers have heads carrying lifting tools that release the tool from the tank but do not offer completely free access.

Par ailleurs, la configuration à outils plongeants et cuve tournante des pétrins à axe oblique et des pétrins à spirales ne permet pas de rendre la cuve étanche pendant le mélange, rendant ainsi impossibles les mélanges sous vide ou sous pression.In addition, the configuration with plunging tools and rotating bowl kneaders with oblique axis and spiral kneaders does not make the tank tight during mixing, thus making it impossible to mix under vacuum or under pressure.

D'autre part, les parties mécaniques assurant les transmissions et la rotation des outils des mélangeurs de type batteur sont complexes et d'un coût de fabrication élevé.On the other hand, the mechanical parts ensuring the transmissions and the rotation of the tools of mixer type drummer are complex and a high manufacturing cost.

Le but de l'invention est de pallier ces inconvénients de l'art antérieur, tout en assurant une succession d'étirement cisaillement de la pâte qui soit optimale pour le pétrissage d'une pâte alimentaire à base de farine et d'eau.The object of the invention is to overcome these drawbacks of the prior art, while ensuring a succession of shear stretching of the dough which is optimal for kneading a food dough based on flour and water.

A cet effet, l'invention a comme premier objet un mélangeur comprenant au moins deux outils de mélange, un bâti supportant d'une part une cuve pour contenir la matière à mélanger et d'autre part des moyens de motorisation pour entraîner en rotation les outils de mélange caractérisé en ce que chaque outil de mélange comprend un arbre monté en rotation dans le fond de la cuve et qui coopère avec les moyens de motorisation provoquant la rotation desdits outils de mélange.For this purpose, the invention has as a first object a mixer comprising at least two mixing tools, a frame supporting on the one hand a tank for containing the material to be mixed and on the other hand motorization means for driving in rotation the mixing tools characterized in that each mixing tool comprises a shaft rotatably mounted in the bottom of the tank and which cooperates with the drive means causing the rotation of said mixing tools.

Les outils de mélange étant fixés sur le fond de la cuve, le dessus de celle-ci est complètement libéré pour les opérations de chargement et de déchargement ainsi que pour l'ajout d'ingrédients pendant la préparation.The mixing tools are fixed on the bottom of the tank, the top of the tank is completely released for loading and unloading operations as well as for the addition of ingredients during preparation.

Selon une réalisation, les moyens de motorisation entraînent en outre la cuve en rotation et le fond de la cuve est solidaire d'un arbre relié aux moyens de motorisation pour entraîner la cuve en rotation, de sorte que la rotation de la cuve provoque la rotation desdits outils de mélange.According to one embodiment, the drive means further drive the vessel in rotation and the bottom of the vessel is integral with a shaft connected to the drive means for driving the vessel in rotation, so that the rotation of the vessel causes the rotation said mixing tools.

Le principe d'entraînement des outils par la rotation de la cuve permet de n'employer qu'une seule motorisation associée à une transmission très simple et compacte participant ainsi à une machine simple; fiable et d'un coût de fabrication bien inférieur aux réalisations de l'art antérieur.The principle of driving the tools by the rotation of the tank allows to use a single motorization associated with a very simple and compact transmission thus participating in a simple machine; reliable and a manufacturing cost much lower than the achievements of the prior art.

De même, le bâti, n'ayant plus à assurer des fonctions complexes de support des différentes motorisations, de la cuve et des outils, se réduit à un simple support de l'ensemble cuve - motorisation - transmission.Likewise, the frame, no longer having to provide complex support functions for the different engines, the tank and the tools, is reduced to a simple support of the tank assembly - motorization - transmission.

La cuve, destinée à tourner sur elle-même pendant le mélange, est de préférence un volume de révolution, par exemple un cylindre, mais elle peut également prendre d'autres formes, par exemple sensiblement oblongue.The tank, intended to turn on itself during mixing, is preferably a volume of revolution, for example a cylinder, but it can also take other forms, for example substantially oblong.

Une réalisation dans laquelle la cuve est sensiblement oblongue permet d'améliorer le cisaillement et l'étirement de la pâte.An embodiment in which the tank is substantially oblong improves the shearing and stretching of the dough.

Selon un mode de réalisation, les moyens de motorisation du mélangeur comprennent un moto-réducteur relié à l'arbre solidaire de la cuve, une couronne dentée traversée par ledit arbre, libre par rapport à cet arbre et solidaire du moto-réducteur, en ce que chaque arbre des outils de mélange porte un pignon en prise directe avec ladite couronne dentée.According to one embodiment, the motorization means of the mixer comprise a geared motor connected to the shaft integral with the tank, a ring gear traversed by said shaft, free with respect to this shaft and integral with the geared motor, in that each shaft of the mixing tools carries a pinion in direct engagement with said ring gear.

La couronne dentée peut être pourvue d'une denture extérieure, les pignons portés par les axes des outils de mélange engrenant sur le périmètre externe de la couronne dentée ou bien, en variante, elle peut être pourvue d'une denture intérieure, les pignons engrenant alors sur le périmètre interne de la couronne dentée.The ring gear can be provided with an external toothing, the pinions carried by the axes of the mixing tools meshing on the outer perimeter of the ring gear or, alternatively, it can be provided with an internal toothing, the pinions meshing then on the inner perimeter of the ring gear.

Dans une variante de ce mode de réalisation, lesdits pignons et ladite couronne dentée sont situés sensiblement dans le même plan et, plutôt que d'être en prise directe, sont en prise par l'intermédiaire d'un moyen de transmission synchrone tel qu'une courroie crantée ou une chaîne. Dans ce cas, la couronne dentée porte autant d'étages de denture qu'il y a de pignons à entraîner, et une chaîne ou courroie relie chaque pignon à l'étage denté correspondant de la couronne.In a variant of this embodiment, said gears and said ring gear are located substantially in the same plane and, instead of being in direct contact, are engaged via a synchronous transmission means such as a toothed belt or chain. In this case, the ring gear carries as many stages of teeth as there are gears to be driven, and a chain or belt connects each pinion to the corresponding toothed stage of the ring gear.

Afin d'améliorer l'efficacité de la phase de mélange, il peut être prévu un autre mode de réalisation dans lequel la cuve de mélange est montée sur un dispositif de basculement permettant de former un angle α entre l'axe de rotation de la cuve et la verticale.In order to improve the efficiency of the mixing phase, another embodiment may be provided in which the mixing tank is mounted on a tilting device making it possible to form an angle α between the axis of rotation of the tank. and the vertical.

Cette disposition a l'avantage de permettre l'inclinaison de la cuve pendant le mélange de manière à s'aider de la gravité pour favoriser la circulation de la matière à mélanger dans la cuve.This arrangement has the advantage of allowing the inclination of the tank during mixing so as to help the gravity to promote the circulation of the material to be mixed in the tank.

La capacité d'inclinaison du mélangeur peut aussi être utilisée pour faciliter le chargement et le déchargement de la matière.The tilting capacity of the mixer can also be used to facilitate the loading and unloading of the material.

Dans cette optique, le bâti peut comprendre, dans ses parties en contact avec le sol, des prises destinées à coopérer avec les fourches d'un chariot élévateur afin de déplacer le mélangeur vers une zone de déchargement, éventuellement en altitude, et de procéder au déchargement en faisant basculer la cuve.In this context, the frame may comprise, in its parts in contact with the ground, catches intended to cooperate with the forks of a forklift to move the mixer to an unloading zone, possibly at altitude, and proceed to unloading by tilting the tank.

Il est également envisageable de doter le mélangeur de caractéristiques supplémentaires pour des mélanges particuliers.It is also conceivable to provide the mixer with additional characteristics for particular mixtures.

La cuve de mélange peut par exemple comprendre un couvercle relevable permettant le mélange dans une enceinte fermée pour des raisons de sécurité.The mixing tank may for example comprise a liftable lid for mixing in a closed chamber for safety reasons.

De plus, un tel couvercle peut être agencé pour, lorsqu'il est en position fermée, former avec la cuve une enceinte étanche comprenant un dispositif d'injection ou de pompage de gaz destiné à créer dans ladite enceinte étanche une atmosphère de mélange ou pétrissage contrôlée. En particulier, en fonction du procédé de pétrissage souhaité, on peut prévoir un pétrissage sous vide partiel ou sous pression de gaz neutre ou de gaz enrichi en oxygène.In addition, such a lid can be arranged to, when in the closed position, form with the tank a sealed chamber comprising a device for injecting or pumping gas intended to create in said sealed chamber a mixing or kneading atmosphere controlled. In particular, depending on the desired kneading process, it is possible to knead under partial vacuum or under pressure of neutral gas or oxygen-enriched gas.

De même, la cuve de mélange peut comprendre, dans l'épaisseur de ses parois, un dispositif de circulation de fluides de chauffage ou de refroidissement afin de procéder à des mélanges à température contrôlée.Similarly, the mixing tank may comprise, in the thickness of its walls, a device for circulating heating or cooling fluids in order to carry out controlled temperature mixtures.

L'invention s'applique plus particulièrement à un pétrin pour pâte alimentaire à base de farine et d'eau, dans lequel les outils de mélange sont des outils de pétrissage.The invention applies more particularly to a food dough mixer based on flour and water, wherein the mixing tools are kneading tools.

L'invention a également pour objet une installation comprenant un mélangeur tel que décrit précédemment ainsi qu'un dispositif de déchargement de la matière mélangée.The invention also relates to an installation comprising a mixer as described above and a device for discharging the mixed material.

Une telle installation comprend un mélangeur à cuve basculante, une trémie et un dispositif de convoyage de la matière mélangée, ces trois éléments étant agencés de telle sorte que, en fin de mélange, le basculement de la cuve du mélangeur provoque la chute de la matière mélangée dans la trémie, celle-ci orientant ladite matière mélangée vers le dispositif de convoyage.Such an installation comprises a tilting bowl mixer, a hopper and a conveying device for the mixed material, these three elements being arranged in such a way that, at the end of mixing, the tilting of the mixer tank causes the material to fall. mixed in the hopper, the latter directing said mixed material to the conveying device.

Dans un mode de réalisation de l'installation, le mélangeur est monté sur un élévateur intégré permettant le déversement de la matière mélangée dans une trémie en altitude.In one embodiment of the installation, the mixer is mounted on an integrated elevator allowing the discharge of the mixed material in a hopper at altitude.

Dans les deux modes de réalisation décrits, chaque outil de pétrissage est agencé de sorte à balayer un volume dont l'enveloppe est d'une part tangente à la périphérie interne de la cuve et d'autre part s'étend à proximité du centre de la cuve.In the two embodiments described, each kneading tool is arranged so as to scan a volume whose envelope is on the one hand tangent to the inner periphery of the tank and on the other hand extends close to the center of the bowl. tank.

Ainsi, le pétrin selon l'invention permet, lors de la rotation des outils, d'obtenir une zone de cisaillement de la pâte au voisinage du centre de la cuve et des zones d'étirement de ladite pâte entre la périphérie interne de la cuve et chacun des outils. En particulier, avec deux outils, la zone de cisaillement est double car formée par deux bras de chacun des outils qui tournent en sens inverse, alors qu'avec trois outils, la zone de cisaillement est triple. Concernant les zones d'étirement, elles sont réalisées de façon particulièrement efficace du fait de la rotation conjointe de la cuve et des outils.Thus, the kneader according to the invention makes it possible, during the rotation of the tools, to obtain a shear zone of the dough in the vicinity of the center of the vessel and stretching zones of the dough between the inner periphery of the vessel. and each of the tools. In particular, with two tools, the shear zone is double because formed by two arms of each of the tools that turn in opposite directions, while with three tools, the shear zone is threefold. Concerning the stretch zones, they are made particularly efficiently because of the joint rotation of the tank and the tools.

Ces réalisations permettent d'obtenir une succession de cisaillements et d'étirements de la pâte, ce qui est bénéfique pour un bon pétrissage d'une pâte alimentaire à base de farine et d'eau.These achievements make it possible to obtain a succession of shears and stretches of the dough, which is beneficial for a good kneading of a pasta made from flour and water.

Dans d'autres modes de réalisation, on peut prévoir un nombre d'outils différents ou de forme différentes de sorte à modifier la nature ou le nombre des zones d'étirement cisaillement de la pâte.In other embodiments, it is possible to provide a number of different tools or of different shape so as to modify the nature or the number of shear stretch zones of the dough.

Selon une variante des modes de réalisation du pétrin selon l'invention, on peut prévoir que la cuve comprenne un couvercle 20 relevable. Selon la représentation de la figure 8, le couvercle 20 est monté sur la cuve 5 au moyen d'un bras articulé 21 au bâti 2 de sorte à pouvoir fermer la cuve 5 de façon hermétique. En particulier, un joint peut être prévu au contact entre la cuve 5 et le couvercle 20.According to a variant of the embodiments of the kneader according to the invention, it can be provided that the vessel comprises a liftable lid. According to the representation of figure 8 , the lid 20 is mounted on the tank 5 by means of an articulated arm 21 to the frame 2 so as to close the tank 5 hermetically. In particular, a seal may be provided in contact between the tank 5 and the lid 20.

En outre, le couvercle comprend une trappe sécurisée 22 d'introduction des ingrédients de la pâte à pétrir, ce qui permet de limiter les contacts entre l'opérateur et la poussière desdits ingrédients lorsque ceux-ci sont introduits dans la cuve. La figure 8 montre également un raccord tournant 23 qui est agencé pour être associé à la trappe 22 de sorte à permettre l'injection d'un gaz ou le pompage.In addition, the lid comprises a secure hatch 22 for introducing the ingredients of the dough, which limits the contact between the operator and the dust of said ingredients when they are introduced into the tank. The figure 8 also shows a rotating connection 23 which is arranged to be associated with the flap 22 so as to allow the injection of a gas or pumping.

L'ensemble cuve - outils de mélange - motorisation - transmission est ainsi porté par le support 3 du moto-réducteur 4 et peut s'incliner par rapport au bâti 2.The tank assembly - mixing tools - motorization - transmission is thus carried by the support 3 of the geared motor 4 and can tilt relative to the frame 2.

Le mélangeur 1 que l'on vient de décrire fonctionne de la manière indiquée ci-après.The mixer 1 which has just been described operates as indicated below.

La cuve 5 est entraînée en rotation par le moto-réducteur 4. Ce mouvement de révolution de la cuve 5 entraîne les axes des outils de mélange 6a, 6b à décrire une trajectoire circulaire, autour de l'axe de rotation de la cuve 5, en faisant rouler les pignons 10a, 10b sur la couronne dentée fixe 8, provoquant ainsi la rotation des outils 6a, 6b.The tank 5 is rotated by the gear motor 4. This movement of revolution of the tank 5 causes the axes of the mixing tools 6a, 6b to describe a circular path around the axis of rotation of the tank 5, by rolling the pinions 10a, 10b on the fixed ring gear 8, thereby causing the tools 6a, 6b to rotate.

Selon une réalisation, la cuve peut être fixe et seule les outils de mélange 6a et 6b sont entraînés en rotation par les moyens de motorisation.In one embodiment, the tank can be fixed and only the mixing tools 6a and 6b are rotated by the drive means.

La conception générale du mélangeur est telle que l'ensemble comprenant la cuve 5, le moto-réducteur 4 et les moyens de transmission est en liaison pivot avec le socle 2 et permet d'incliner la cuve 5 de sorte que l'axe de rotation de la cuve 5 forme un angle α avec la verticale (voir figure 1).The general design of the mixer is such that the assembly comprising the tank 5, the geared motor 4 and the transmission means is in pivot connection with the base 2 and allows to tilt the tank 5 so that the axis of rotation of the tank 5 forms an angle α with the vertical (see figure 1 ).

Il est ainsi possible de former un angle α pendant le mélange, ceci permettant d'augmenter l'efficacité du mélange vis-à-vis des zones mortes c'est-à-dire des volumes de la cuve 5 qui ne sont pas balayés par les outils 6a, 6b et où la matière mélangée a tendance à stagner.It is thus possible to form an angle α during the mixing, this making it possible to increase the efficiency of the mixture with respect to dead zones, that is to say volumes of the tank 5 which are not swept by the tools 6a, 6b and where the mixed material tends to stagnate.

Avec une inclinaison appropriée durant la phase de mélange, la matière se trouvant dans les zones mortes tombe par gravité dans les volumes balayés par les outils.With proper inclination during the mixing phase, the material in the dead zones falls by gravity into the volumes swept by the tools.

Il est aussi possible d'utiliser les possibilités d'inclinaison de la cuve 5, en fin de mélange, à des fins de déchargement de la matière mélangée.It is also possible to use the tilting possibilities of the tank 5, at the end of mixing, for the purpose of unloading the mixed material.

On peut prévoir un déchargement très simple en équipant le mélangeur de prises 11 pour fourches de chariot élévateur et, au moment du déchargement, porter le mélangeur à l'endroit et à la hauteur voulue puis faire basculer fortement la cuve de manière à la vider. La figure 4 donne un exemple d'un tel mélangeur.A very simple unloading can be provided by equipping the mixer with sockets 11 for forklift forks and, at the time of unloading, bring the mixer to the desired position and height then tilt the tank strongly to empty it. The figure 4 gives an example of such a mixer.

Des installations permettant le déchargement sont également présentées aux figures 5 et 6.Facilities for unloading are also presented to figures 5 and 6 .

Sur la figure 5, il s'agit d'un mélangeur fixé à la hauteur du sol, déversant dans une trémie 12 en contrebas.On the figure 5 it is a mixer attached to the ground, pouring into a hopper 12 below.

La figure 6 décrit un mélangeur fixé sur une colonne élévatrice 14 et déversant dans une trémie 15 en altitude.The figure 6 discloses a mixer attached to a riser 14 and discharging into a hopper 15 at altitude.

La machine décrite ci-dessus présente notamment les avantages de :

  • permettre un accès total à la cuve 5 pour la phase de chargement ou de déchargement ;
  • disposer d'un mécanisme simple et robuste donc fiable ;
  • être réalisable à un coût inférieur à celui des machines équivalentes grâce à la réduction du nombre et à la simplification des pièces en mouvement ;
  • permettre un pétrissage sous atmosphère contrôlée ;
  • limiter les contacts entre l'opérateur et les poussières issues des ingrédients de la pâte à pétrir ;
  • fournir des zones de cisaillement et d'étirement de la pâte qui sont modulables et dont la cinématique est adaptée pour un pétrissage optimal d'une pâte alimentaire à base de farine et d'eau.
The machine described above has the advantages of:
  • allow full access to the tank 5 for the loading or unloading phase;
  • have a simple and robust mechanism so reliable;
  • be feasible at a lower cost than equivalent machines by reducing the number and simplification of moving parts;
  • allow mixing under a controlled atmosphere;
  • limit contact between the operator and the dusts from the dough ingredients;
  • provide shear zones and stretching of the dough that are flexible and whose kinematics are suitable for optimal kneading of a pasta dough based on flour and water.
