Abstract

The invention concerns a method and an equipment for making ice cubes of liquid or pasty products comprising a honeycomb conveyor belt transporting the product to be processed along a path passing through at least the following three zones: a zone for metering and depositing the product to be processed in the cells; a cold input zone where preferably a cryogenic liquid solution completes the freezing of the ice cubes; and a stripping zone. Further, the honeycomb belt is bottomless, and located in an upstream zone opposite a cooled surface acting as a base of the partial mold formed by the cells, so as to harden the part of the product in contact with the cooled surface, thereby producing the base of the ice cube.

Description

Générateur de glaçons de produits liquides ou pâteux. Ice maker of liquid or pasty products.
La présente invention concerne le domaine des procédés et installations de traitement cryogénique de produits, notamment alimentaires, et tout particulièrement les procédés et installations de fabrication de « glaçons » ou « pellets » ou « pastilles » de produits liquides ou pâteux. On peut citer dans cette catégorie les exemples de glaçons de sauce, de purée, de jus ou d'autres liquides.The present invention relates to the field of processes and installations for the cryogenic treatment of products, especially food products, and particularly the processes and installations for manufacturing "ice cubes" or "pellets" or "pellets" of liquid or pasty products. Examples in this category are icicles of sauce, puree, juice or other liquids.
On a vu apparaître ces dernières années des procédés mettant en œuvre, pour réaliser de tels glaçons, des tunnels à tapis alvéolés, donc constitués d'un enchaînement articulé de petits moules, qui sont remplis du mélange à congeler et dont le démoulage permet d'obtenir les glaçons de forme et de caractéristiques voulues.In recent years, processes have been implemented using honeycombed belt tunnels for making such ice cubes, and therefore consisting of an articulated series of small molds, which are filled with the mixture to be frozen and whose demolding makes it possible to obtain ice cubes of desired shape and characteristics.
On trouve dans cette catégorie de procédés le document EP-1 115 637. Un des problèmes bien connu de ces fabrications est l'adhérence des pastilles sur le tapis ou support utilisé et donc les difficultés de démoulage, donnant lieu à perte de matériau, marquage des surface des pastilles etc..This category of processes can be found in document EP-1 115 637. One of the well-known problems of these fabrications is the adhesion of the pellets to the carpet or support used and therefore the difficulties of demolding, giving rise to loss of material, marking. pellet surface etc.
Le document EP-1 115 637 propose pour sa part une structure particulière de tapis alvéolé facilitant le démoulage et limitant les pertes de matière : il propose de procéder à un pré-refroidissement du tapis par trempage dans un bain de liquide cryogénique, avant de verser dans les alvéoles le liquide à traiter, ce qui leur permet d'obtenir un croutage des surfaces extérieures des pastilles, les produits sont ensuite démoulés et transférés vers un surgélateur plus classique pour terminer la surgélation à cœur des pastilles.The document EP-1 115 637 for its part proposes a particular honeycombed carpet structure facilitating demolding and limiting losses of material: it proposes to pre-cool the carpet by soaking in a bath of cryogenic liquid, before pouring in the cells the liquid to be treated, which allows them to obtain crusting of the outer surfaces of the pellets, the products are then removed from the mold and transferred to a more conventional freezer to complete deep freezing pellets heart.
C'est donc un des objectifs de la présente invention de proposer un nouveau procédé de fabrication de pastilles ou glaçons congelés permettant non seulement de solutionner les problèmes d'adhérence et de perte de matériau mais également de proposer une solution plus simple intégrable au sein d'un unique matériel. Comme on le verra plus en détail ci-dessous, le procédé de fabrication de glaçons de produits liquides ou pâteux selon l'invention se caractérise par la mise en œuvre des mesure suivantes :It is therefore one of the objectives of the present invention to propose a novel process for the production of frozen pellets or ice cubes, which not only makes it possible to solve problems of adhesion and loss of material but also to propose a simpler solution that can be integrated within a unique material. As will be seen in more detail below, the process for manufacturing ice cubes of liquid or pasty products according to the invention is characterized by the implementation of the following measures:
- la mise en œuvre d'un tapis alvéolé sans fonds, transporté dans l'équipement le long d'un trajet passant par les différentes zones de l'équipement ;- The implementation of a bottomless honeycomb carpet, transported in the equipment along a path through the different areas of the equipment;
- dans une zone amont de l'équipement on procède au dosage et à la dépose du fluide à traiter (sauce, jus...) dans les alvéoles du tapis ;in an upstream zone of the equipment, the dosing and dispensing of the fluid to be treated (sauce, juice, etc.) is carried out in the cavities of the carpet;
- dans cette zone de dépose le tapis est situé en regard d'une surface refroidie (par exemple une plaque métallique d'échangeur à fluide cryogénique) qui sert de fond du moule partiel que constituent les alvéoles.in this removal zone, the belt is located opposite a cooled surface (for example a metal plate for a cryogenic fluid exchanger) which serves as the bottom of the partial mold that constitutes the cells.
Dans cette première zone on procède au refroidissement ou croutage de la partie du liquide en contact avec la surface refroidie pour en quelque sorte créer le fond du glaçon . - de là le tapis poursuit son chemin dans l'équipement pour amener les glaçons « pré-croutés » dans une zone où est réalisé un apport de froid, permettant de réaliser la congélation des glaçons en tout ou parties, mais préférentiellement la congélation à cœur (on conçoit que selon les applications visées en aval il ne soit pas toujours nécessaire de disposer d'une congélation à cœur), apport de froid par tout moyen même si l'on préfère selon la présente invention réaliser cet apport de froid en faisant défiler (s'immerger) le tapis dans un bain d'un liquide cryogénique, sur une hauteur préférentiellement au moins égale à la hauteur du lit de produit dans les moules. Pour des raisons qu'on détaillera plus en détails ci-dessous, d'autres modes d'apport de froids peuvent être envisagés selon les applications (froid mécanique, sprays, tapis poreux du type de celui du document EP-A-505 222...) mais ils ne sont pas préférés selon la présente invention pour des raisons de productivité (il faut aller vite) mais aussi pour limiter les risques de souffler le fluide, par exemple la sauce.In this first zone is carried out cooling or crusting of the liquid part in contact with the cooled surface to somehow create the bottom of the ice cube. - From there the carpet continues its way in the equipment to bring the ice cubes "pre-croutés" in a zone where a contribution of cold is made, allowing to freeze the ice cubes in all or parts, but preferentially the freezing to heart (It is conceivable that according to the applications referred downstream it is not always necessary to have a freezing at heart), supply of cold by any means even if it is preferred according to the present invention achieve this intake of cold by scrolling (immerse) the carpet in a bath of a cryogenic liquid, at a height preferably at least equal to the height of the product bed in the molds. For reasons which will be detailed in more detail below, other methods of supplying cold can be envisaged according to the applications (mechanical cold, sprays, porous mats of the type of that of document EP-A-505 222. ..) but they are not preferred according to the present invention for reasons of productivity (it must go fast) but also to limit the risk of blowing the fluid, for example the sauce.
- le tapis quitte alors la zone d'apport de froid, par exemple la zone d'immersion dans un bain, pour aborder une zone de démoulage, par exemple constituée par le fait qu'en sortie d'équipement le tapis s'enroule autour d'un arbre équipé d'empreintes positives réalisant non seulement l'entraînement du tapis mais pouvant s'enfoncer dans les orifices du tapis -puisqu'il est sans fonds- pour pousser les glaçons hors des moules.the carpet then leaves the cold supply zone, for example the immersion zone in a bath, to approach a demolding zone, for example constituted by the fact that at the end of equipment the carpet wraps around of a tree equipped with positive imprints realizing not only the drive of the carpet but being able to sink in the orifices of the carpet - since it is without funds - to push the ice cubes out of the molds.
La présente invention concerne alors un équipement de fabrication de glaçons de produits liquides ou pâteux, comportant un tapis convoyeur alvéolé apte à transporter le produit à traiter dans l'équipement le long d'un trajet de traitement passant par les différentes zones de l'équipement, et mettant en œuvre les mesures suivantes :The present invention thus relates to ice-making equipment for liquid or pasty products, comprising a honeycomb conveyor belt capable of transporting the product to be treated in the equipment along a treatment path passing through the different zones of the equipment. , and implementing the following measures:
- l'équipement comporte au moins successivement les trois zones suivantes : i) une zone amont comportant un dispositif de dosage et dépose du produit à traiter dans les alvéoles du tapis ; j) une zone d'apport de froid ; k) une zone de démoulage.the equipment comprises at least successively the following three zones: i) an upstream zone comprising a metering device and depositing the product to be treated in the cells of the carpet; j) a cold supply zone; k) a demolding area.
- ledit tapis convoyeur est un tapis alvéolé sans fonds; - dans ladite zone amont, le tapis est situé en regard d'une surface refroidie qui sert de fond du moule partiel que constituent les alvéoles.said conveyor belt is a hollow honeycomb mat; - In said upstream zone, the belt is located opposite a cooled surface which serves as the bottom of the partial mold that constitute the cells.
Dans des modes de réalisation préférés de l'invention, on peut éventuellement avoir recours en outre à l'une et/ou à l'autre des dispositions suivantes :In preferred embodiments of the invention, one or more of the following may also be used:
- ladite surface refroidie est une plaque métallique d'un échangeur à liquide cryogénique.said cooled surface is a metal plate of a cryogenic liquid exchanger.
- ladite zone d'apport de froid est un bain de liquide cryogénique dans lequel vient défiler le tapis au sortir de ladite zone amont, la hauteur du bain étant préférentiel lement au moins égale à la hauteur du lit de produit dans les alvéoles.said cold supply zone is a bath of cryogenic liquid in which the carpet comes out of said upstream zone, the height of the bath preferably being at least equal to the height of the product bed in the cells.
- ladite zone d'apport de froid comprend un ou plusieurs modes d'apport de froids parmi les modes suivants : le froid mécanique, des sprays de liquide cryogénique, un tapis poreux impregnable de liquide cryogénique. - la zone de démoulage comprend un arbre équipé d'empreintes positives autour duquel le tapis s'enroule, apte ainsi à réaliser non seulement l'entraînement du tapis mais également à s'enfoncer dans les alvéoles du tapis pour pousser les glaçons hors de ces alvéoles. L'invention concerne également un procédé de fabrication de glaçons de produits liquides ou pâteux, dans un équipement comportant un tapis convoyeur alvéolé apte à transporter le produit à traiter dans l'équipement le long d'un trajet de traitement passant par les différentes zones de l'équipement, l'équipement comportant au moins les trois zones suivantes : i) une zone amont comportant un dispositif de dosage et dépose du produit à traiter dans les alvéoles du tapis ; j) une zone d'apport de froid ; k) une zone de démoulage. procédé mettant en œuvre les mesures suivantes :said cold supply zone comprises one or more modes of supply of colds among the following modes: mechanical cold, cryogenic liquid sprays, impregnable porous mat of cryogenic liquid. the demolding zone comprises a tree equipped with positive impressions around which the carpet rolls up, thus able to achieve not only the training of the carpet but also to penetrate into the cells of the carpet to push the ice cubes out of these alveoli. The invention also relates to a method for manufacturing ice cubes of liquid or pasty products, in equipment comprising a honeycomb conveyor belt capable of transporting the product to be treated in the equipment along a treatment path passing through the different zones of the machine. equipment, equipment comprising at least the following three zones: i) an upstream zone comprising a metering device and depositing the product to be treated in the cells of the belt; j) a cold supply zone; k) a demolding area. method implementing the following measures:
- ledit tapis convoyeur est un tapis alvéolé sans fonds;said conveyor belt is a hollow honeycomb mat;
- dans la zone amont de dépose du produit à traiter, le tapis est situé en regard d'une surface refroidie qui sert de fond du moule partiel que constituent les alvéoles, afin de réaliser le croutage de la partie du produit en contact avec la surface refroidie et créer ainsi le fond du glaçon ;in the upstream zone for depositing the product to be treated, the belt is located opposite a cooled surface which serves as the bottom of the partial mold that constitute the cells, in order to crust the portion of the product in contact with the surface; cooled and thus create the bottom of the ice cube;

Selon un des modes de réalisation du procédé selon l'invention, on réalise la congélation des glaçons dans la zone d'apport de froid en y faisant défiler le tapis dans un bain d'un liquide cryogénique, dont la hauteur est préférentiellement au moins égale à la hauteur du lit de produit dans les alvéoles.According to one of the embodiments of the process according to the invention, the ice cubes are frozen in the cold supply zone by moving the carpet in a bath of a cryogenic liquid, the height of which is preferably at least equal to at the height of the product bed in the cells.
D'autres caractéristiques et avantages ressortiront de la description suivante, donnée uniquement à titre d'exemple et faite en référence aux figures annexées sur lesquelles :Other characteristics and advantages will emerge from the following description, given solely by way of example and with reference to the appended figures in which:
- la figure 1 est une représentation schématique en section d'une installation de génération de glaçons conforme à l'invention ;FIG. 1 is a diagrammatic representation in section of an ice-making installation according to the invention;
- la figure 2 permet de mieux visualiser un mode de réalisation du tapis alvéolé « sans fond ». La présente invention présente l'avantage d'être mise en œuvre dans un équipement unique et complet, allant de la formation des glaçons, leur congélation et leur démoulage.- Figure 2 allows to better visualize an embodiment of the honeycomb carpet "bottomless". The present invention has the advantage of being implemented in a single and complete equipment, ranging from the formation of ice cubes, their freezing and demolding.
Il est traversé d'une extrémité à l'autre par un tapis convoyeur alvéolé, mais avec le point important que le tapis, et donc les alvéoles, est sans fond (ce que l'on visualise parfaitement au niveau de la figure 2 qui représente un exemple de réalisation d'un tel tapis convenant pour la mise en œuvre de l'invention).It is crossed from one end to the other by a honeycomb conveyor belt, but with the important point that the carpet, and therefore the cells, is bottomless (which is perfectly seen in Figure 2 which represents an embodiment of such a carpet suitable for the implementation of the invention).
Dans une zone amont, le tapis rencontre un dispositif de dosage et dépose du produit (par exemple une sauce) à traiter dans les alvéoles du tapis. Conformément à l'invention, dans cette zone amont, le tapis est situé en regard d'une surface refroidie (ici un échangeur contact à l'azote liquide) qui sert de fond du moule partiel que constituent les alvéoles. On a compris à la lumière de la description qui précède que cette première zone permet de refroidir/croûter la portion de produit en contact avec la zone refroidie et donc en quelque sorte créer le fond du glaçon, ce qui facilitera le démoulage ultérieur.In an upstream zone, the carpet meets a dosing device and deposits the product (for example a sauce) to be treated in the cells of the carpet. According to the invention, in this upstream zone, the belt is located opposite a cooled surface (here a contact exchanger with liquid nitrogen) which serves as the bottom of the partial mold that constitute the cells. It is understood from the foregoing description that this first zone makes it possible to cool / crust the portion of product in contact with the cooled zone and thus to some extent create the bottom of the ice cube, which will facilitate the subsequent demolding.
En effet, en sortie de cette zone amont, le tapis quitte le contact avec la surface refroidie et aborde une zone d'apport de froid, ici une zone d'immersion dans un bain d'azote liquide, bain dont la hauteur est préférentiellement au moins égale à l'épaisseur du lit de sauce dans les alvéoles, afin d'obtenir la congélation à cœur des glaçons pré-croûtés.Indeed, at the exit of this upstream zone, the carpet leaves the contact with the cooled surface and approaches a cold supply zone, here an immersion zone in a bath of liquid nitrogen, bath whose height is preferably at less equal to the thickness of the bed of sauce in the cells, in order to obtain freezing heart pre-crusted ice.
Comme on l'a déjà mentionné plus haut, d'autres modes d'apport de froids peuvent être utilisés en complément ou en remplacement du bain cryogénique dans la zone d'apport de froid, selon notamment l'application ultérieure qui est visée pour de tels glaçons (la figure 1 illustre par exemple la présence additionnelle de ventilateurs et de sprays de fluide cryogénique), mais on a déjà noté que ces modes ne sont pas préférés selon la présente invention pour des raisons de productivité (il faut aller vite) mais aussi pour limiter les risques de souffler la sauce par l'action de tels ventilateurs ou sprays.As already mentioned above, other methods of supplying cold can be used in addition to or in replacement of the cryogenic bath in the cold supply zone, depending in particular on the subsequent application which is intended for such ice cubes (Figure 1 illustrates for example the additional presence of fans and cryogenic fluid sprays), but it has already been noted that these modes are not preferred according to the present invention for reasons of productivity (we must go fast) but also to limit the risk of blowing the sauce by the action of such fans or sprays.
Le tapis quitte ensuite la zone d'apport de froid pour aborder une zone de démoulage, qui pour le mode de réalisation représenté ici est constituée par le fait qu'en sortie d'équipement le tapis s'enroule autour d'un arbre équipé d'empreintes positives réalisant non seulement l'entraînement du tapis mais pouvant s'enfoncer dans les orifices du tapis -puisqu'il est sans fonds- pour pousser les glaçons hors des moules alvéoles.The carpet then leaves the cold supply zone to approach a demoulding zone, which for the embodiment represented here is constituted by the fact that, at the exit of equipment, the carpet wraps around a tree equipped with positive impressions realizing not only the drive of the carpet but being able to be inserted in the orifices of the carpet - since it is without bottoms- to push the ice cubes out of the alveoli molds.
Si on a décrit dans ce qui précède en exemple de réalisation de glaçons carrés, on conçoit que les alvéoles du tapis pourront adopter toute autre forme et notamment cylindrique, rectangulaire ou encore fantaisie, par exemple sous forme de petits personnages. If it has been described in the foregoing example embodiment of square ice cubes, it is conceivable that the alveoli of the carpet can adopt any other shape and in particular cylindrical, rectangular or fantasy, for example in the form of small characters.
