Description

Procédé et dispositif pour éliminer l'oxygène de l'espace de tête d'un emballage. Method and device for removing oxygen from the headspace of a package.
L'invention concerne un procédé d'élimination d'oxygène de l'espace de tête d'un emballage rempli aseptiquement, dans lequel on remplit l'emballage sous atmosphère d'air stérile, on injecte ensuite de l'azote stérile avec une buse disposée directement au-dessus de l'ouverture dudit emballage à température ambiante et sous la pression atmosphérique dans une atmosphère d'air stérile et on scelle l'emballage entre deux éléments de scellage. L'invention concerne en outre le dispositif utilisé pour la mise en oeuvre de ce procédé.The invention relates to a method for removing oxygen from the headspace of an aseptically filled package, in which the package is filled under an atmosphere of sterile air, then sterile nitrogen is injected with a nozzle. disposed directly above the opening of said package at room temperature and at atmospheric pressure in a sterile air atmosphere and the package is sealed between two sealing elements. The invention further relates to the device used for implementing this method.
Dans le domaine du remplissage aseptique avec certains types de machine, il n'est pas possible de remplir un emballage et de le sceller sans y laisser un faible volume gazeux, appelé espace de tête. Comme on travaille normalement dans des systèmes avec de l'air stérile, cet espace de tête contient de l'ordre de 20% d'oxygène. La présence d'oxygène a un effet négatif, en ce sens que lors de la conservation du produit contenu dans ledit emballage, il arrive fréquemment que ce produit soit sensible à l'oxygène, ce qui conduit ainsi à une dégradation de son goût et/ou de certains ingrédients, tels que les vitamines et les sels minéraux. Ce phénomène est inacceptable pour le consommateur ou pour des raisons de législation alimentaire. On a déjà envisagé une solution dans laquelle on cherche à réduire l'espace de tête : on opère dans ce cas en remplaçant juste avant le scellage l'air par de la vapeur d'eau. L'inconvénient de ce système est cependant que la vapeur d'eau se condense sur des surfaces froides : la conséquence est un risque inacceptable d'infection pour les produits neutres et faiblement acides. Une seconde solution consiste à réduire l'espace de tête avec des éléments mécaniques en pressant l'emballage : mais il n'est cependant pas possible d'éliminer totalement ledit espace. Le brevet DE 3108817 concerne également un dispositif permettant d'éliminer l'oxygène de l'espace de tête d'un emballage. Dans ce dispositif, la buse permettant d'injecter l'azote est solidaire de l'un des éléments de scellage, ce qui diminue l'efficience de l'arrivée d'azote, car ladite buse bouge et le jet d'azote change de direction. les brevets US 4,934,127 et EP 479,037 concernent également des dispositifs pour éliminer l'oxygène de l'espace de tête d'un emballage. L'inconvénient de ces dispositifs est que le scellage de l'emballage se fait en aval de la station d'injection d'azote, ce qu a pour conséquence de laisser repartir la quantité d'azote introduite au préalable.In the field of aseptic filling with certain types of machine, it is not possible to fill a package and seal it without leaving a small volume of gas, called the headspace. As we normally work in systems with sterile air, this headspace contains around 20% oxygen. The presence of oxygen has a negative effect, in the sense that during the conservation of the product contained in said packaging, it frequently happens that this product is sensitive to oxygen, which thus leads to a degradation of its taste and / or certain ingredients, such as vitamins and minerals. This phenomenon is unacceptable to the consumer or for reasons of food law. We have already considered a solution in which we seek to reduce the head space: we operate in this case by replacing the air just before sealing with water vapor. The disadvantage of this system is however that the water vapor condenses on cold surfaces: the consequence is an unacceptable risk of infection for neutral and weakly acidic products. A second solution consists in reducing the head space with mechanical elements by pressing the packaging: but it is not however, it is not possible to completely eliminate said space. Patent DE 3108817 also relates to a device making it possible to remove oxygen from the head space of a package. In this device, the nozzle for injecting nitrogen is integral with one of the sealing elements, which decreases the efficiency of the nitrogen supply, since said nozzle moves and the nitrogen jet changes direction. US patents 4,934,127 and EP 479,037 also relate to devices for removing oxygen from the headspace of a package. The disadvantage of these devices is that the packaging is sealed downstream of the nitrogen injection station, which has the consequence of allowing the quantity of nitrogen introduced beforehand to start again.
Le but de la présente invention est la mise au point d'un procédé permettant d'éliminer l'oxygène de l'espace de tête d'un emballage rempli aseptiquement de manière efficiente. Par éliminer, on entend le fait d'atteindre une teneur en oxygène très faible dans l'espace de tête, à savoir de l'ordre de 2% et même moins.The object of the present invention is the development of a process making it possible to remove oxygen from the head space of a package aseptically filled in an efficient manner. By eliminating is meant reaching a very low oxygen content in the headspace, namely of the order of 2% and even less.
Selon le procédé de l'invention, or. injecte l'azote stérile à partir de la buse qui est fixe et disposée entre les deux éléments de scellage mobiles.According to the method of the invention, or. injects sterile nitrogen from the nozzle which is fixed and arranged between the two movable sealing elements.
L'emballage utilisé peut être de tout type, pouvu que sa partie supérieure soit scellable.The packaging used can be of any type, provided that its upper part is sealable.
Le produit de remplissage de l'emballage peut être de tout type liquide du domaine alimentaire, par exemple un produit: à base de lait, de us de fruit ou d'eau, pouvant en outre contenir une partie αe morceaux. Or. préfère toutThe filling product for the packaging can be of any liquid type from the food industry, for example a product: based on milk, fruit or water, which may also contain a portion of pieces. Or. Prefer everything
* particulièrement les produits sensibles à l'oxygène et faiblement acides, comre les produits diététiques contenant des vitamines et des sels minéraux. Le but est d'obtenir des produits à longue durée de conservation, pour lesquels il n'y a pas de dégradation du goût et/ou de certains ingrédients lors du stockage. * particularly oxygen sensitive and weakly acidic products, such as dietetic products containing vitamins and mineral salts. The goal is to get products with a long shelf life, for which there is no degradation of taste and / or certain ingredients during storage.
Le procédé est mis en oeuvre sur une ligne de fabrication industrielle classique, dans laquelle il y a notamment un compartiment de remplissage et un compartiment de scel¬ lage : il faut rajouter selon l'invention dans le compartiment de scellage une étape d'injection d'azote.The method is implemented on a conventional industrial manufacturing line, in which there is in particular a filling compartment and a sealing compartment: an injection step must be added according to the invention to the sealing compartment. 'nitrogen.
Les deux compartiments de remplissage et de scellage sont sous courant d'air stérile de manière à y créer des conditions de turbulence : la vitesse d'injection de l'azote est supérieure à la vitesse d'injection d'air stérile. Pour parvenir à un espace de tête ayant une teneur en oxygène de moins de 2 %, il faut travailler avec un débit d'azote par ligne compris entre 100 et 800 1/min à pression atmosphérique.The two filling and sealing compartments are supplied with sterile air so as to create turbulence conditions: the nitrogen injection speed is greater than the sterile air injection speed. To achieve a headspace with an oxygen content of less than 2%, it is necessary to work with a nitrogen flow rate per line of between 100 and 800 l / min at atmospheric pressure.
La durée d'injection d'azote par emballage est de l'ordre de la seconde. Cette rapide injection d'azote permet d'économiser la quantité d'azote et limite la longueur de la ligne de production. On peut aussi bien opérer avec une arrivée d'azote continue que discontinue.The duration of nitrogen injection per package is of the order of a second. This rapid nitrogen injection saves the amount of nitrogen and limits the length of the production line. It is equally possible to operate with a continuous nitrogen supply as well as a discontinuous one.
On améliore l'efficacité d'élimination de l'air résiduel dans l'espace de tête grâce à une disposition spécifique de l'arrivée du courant d'azote : on opère dans ce cas, avec l'azote arrivant depuis le haut sous un angle compris entre 40 et 50° par rapport à la verticale et à contre-courrant du sens de déplacement des emballages.The efficiency of elimination of residual air in the head space is improved by a specific arrangement of the arrival of the nitrogen current: in this case, the operation is carried out with the nitrogen arriving from above under a angle between 40 and 50 ° with respect to the vertical and against the direction of movement of the packaging.
L'invention concerne en outre le dispositif utilisable pour la mise en oeuvre du procédé décrit ci-dessus. Ce dispositif comprend un compartiment de remplissage de produit dans un emballage, un compartiment de scellage dudit emDallage avec deux éléments de scellage et un dispositif transporteur pour véhiculer les emballages dans les deux compartiments, le second compartiment comportant une buse fixe pour injecter l'azote, celle-ci étant disposée entre les éléments de scellage mobiles.The invention further relates to the device which can be used for implementing the method described above. This device includes a product filling compartment in a packaging, a sealing compartment of said packaging with two sealing elements and a conveyor device for conveying the packaging in the two compartments, the second compartment comprising a fixed nozzle for injecting nitrogen, the latter being disposed between the mobile sealing elements.
Le dispositif transporteur à un système d'avancée au pas-à- pas et on arrive à une cadence de remplissage classique a ce type de ligne. Il est bien entendu que dans la présente description, tout ce qui est dit concerne un mode de remplissage aseptique : l'azote et l'air utilisé sont presténlises.The conveyor device has a step-by-step advancement system and a conventional filling rate is reached for this type of line. It is understood that in the present description, everything that is said relates to an aseptic filling mode: the nitrogen and the air used are presténlises.
On dispose dans la buse d'arrivée d'azote un répartiteur et des moyens supplémentaires, tels qu'une ou plusieurs plaques métalliques permettant d'obtenir des flux uniformes à la sortie de la buse.There is a distributor and additional means in the nitrogen inlet nozzle, such as one or more metal plates making it possible to obtain uniform flows at the outlet of the nozzle.
La buse est positionnée de manière à ce qu'elle fasse un angle compris entre 40 et 50° avec la verticale.The nozzle is positioned so that it makes an angle between 40 and 50 ° with the vertical.
Il faut également que le flux d'azote arrive sur une largeur suffisante pour bien déplacer l'air résiduel αe l'espace de tête : on prévoit une largeur de buse supérieure a la largeur d'ouverture de l'emDallage. La suite de la description est faite en référence aux dessins sur lesquels :It is also necessary that the nitrogen flow arrives over a width sufficient to properly move the residual air to the headspace: a nozzle width is provided which is greater than the opening width of the packaging. The following description is made with reference to the drawings in which:
Fig. 1 est une représentation schématique du dispositif selon l'invention, dans l'étape d'injection d'azote etFig. 1 is a schematic representation of the device according to the invention, in the nitrogen injection step and
Fig. 2 est une représentation schématique au même dispositif dans l'étape de scellage.Fig. 2 is a schematic representation of the same device in the sealing step.
Les emballages 1 arrivent par le dispositif transporteur 2 dans le sens des flecnes 3 dans le compartiment ce remplissage aseptique 4, puis dans le compartiment αe scellage 5. De l'air stérile est injecté dans les deux compartiments précités respectivement par les conduites 6 et 7. Le produit 8 arrive par le système de remplissage 9 et est dosé dans l'emballage 1 grâce à la buse de remplissage 10. Le compartiment de scellage 5 comprend la buse fixe 11 d'injection d'azote, l'azote arrivant par la conduite 12 ainsi que les deux éléments de scellage 13,14.The packages 1 arrive by the conveyor device 2 in the direction of the arrows 3 in the compartment this aseptic filling 4, then in the compartment αe sealing 5. Sterile air is injected into the two aforementioned compartments respectively through lines 6 and 7. The product 8 arrives through the filling system 9 and is dosed in the packaging 1 using the filling nozzle 10. The sealing compartment 5 comprises the fixed nozzle 11 for injecting nitrogen, the nitrogen arriving via line 12 as well as the two sealing elements 13, 14.
Les compartiments de remplissage aseptique 4 et de scellage 5 comportent des ouvertures 15, 16, 17 permettant le passage des emballages 1 sur le dispositif transporteur 2.The aseptic filling 4 and sealing 5 compartments have openings 15, 16, 17 allowing the packaging 1 to pass over the conveyor device 2.
Le fonctionnement du dispositif selon l'invention est le suivant : Le dispositif transporteur 2 a un système d'avancée pas-à-pas. L'emballage 1 est positionné sous la buse de remplissage 10, qui délivre alors la dose de produit 8. Le compartiment est en permanence sous atmosphère d'air stérile. Le dispositif transporteur positionne ensuite les autres emballages sous la buse 10 et les emballages remplis arrivent dans le compartiment de scellage 5 et passent sous la buse 11 d'injection d'azote. Le débit d'azote est de 300 1/min, le compartiment de scellage étant lui aussi en permanence sous atmosphère d'air stérile. Dans la Fig. 2, on voit bien l'opération de scellage avec les éléments 13 et 14. Le dispositif transporteur 2 délivre alors les emballages prêts à l'emploi ou au stockage.The operation of the device according to the invention is as follows: The conveyor device 2 has a step-by-step advance system. The package 1 is positioned under the filling nozzle 10, which then delivers the dose of product 8. The compartment is permanently in an atmosphere of sterile air. The conveyor device then positions the other packages under the nozzle 10 and the filled packages arrive in the sealing compartment 5 and pass under the nozzle 11 for injecting nitrogen. The nitrogen flow rate is 300 l / min, the sealing compartment also being permanently in a sterile air atmosphere. In Fig. 2, we can clearly see the sealing operation with the elements 13 and 14. The conveyor device 2 then delivers the packaging ready for use or for storage.
On obtient ainsi selon l'invention des emballages qui peuvent être stockés pendant au moins 6 mois, sans aucune dégradation de la qualité et u goût du produit. Les vitamines ainsi que les sels minéraux sont en outre préservés. Dans -l'exemple précité, on arrive à une teneur en oxygène de 1* dans l'espace de tête. According to the invention, packaging is thus obtained which can be stored for at least 6 months, without any deterioration in the quality and taste of the product. Vitamins and minerals are also preserved. In the example above, we arrive at an oxygen content of 1 * in the headspace.
