  • the method of the present invention is of the kind comprising the following steps: opening the pouch; filling the pouch with selected products; closing the pouch, and it is characterised in that all the aforesaid steps take place in a single environment, isolated from the exterior environment.
  • the method further comprises a step of aspirating air from the isolated environment, at least before the step of closing the pouch, in order to create a predetermined degree of vacuum.
  • the step of closing the pouch takes place by means of heat sealing of edges of the pouch positioned in correspondence with a filling mouth thereof.
  • the method in question further comprises a step of sterilising the isolated environment, before and/or during the step of opening the pouch. In this way, it is possible to assure the filling of the sack in a completely aseptic environment and in a single filling station.
  • the invention achieves other important advantages.
  • the machine of the invention allows to complete the entire cycle for processing the pouch, or the envelope, inside a containment body, or bell, and therefore assures a manipulation of the pouch in a controlled environment or one that is, in any case, protected from external agents, hi particular, the capability to sterilise the bell, or in any case to create a predetermined degree of vacuum in its interior, allows to fill the pouches in a controlled atmosphere. Therefore, a machine in accordance with the invention can advantageously be used to process products which are particularly sensitive to oxygen and/or to contaminants.
  • Another advantage is represented by the fact that such a machine for filling pouches or envelopes is very compact and can be installed even in small facilities.

Abstract

L'invention concerne un procédé de remplissage de sachets ou d'enveloppes, contenant particulièrement des produits alimentaires et/ou pharmaceutiques. Ce procédé consiste à: ouvrir le sachet ; remplir le sachet des produits choisis ; et fermer le sachet. Ce procédé est caractérisé en ce que l'ensemble des opérations précitées ont lieu dans un seul et unique environnement, isolé de l'environnement extérieur. L'invention concerne en outre un dispositif (1) de remplissage de sachets (3) ou d'enveloppes, en particulier de produits alimentaires/ou pharmaceutiques, qui comprend au moins un poste de remplissage (82) doté de moyens qui permettent d'ouvrir le sachet, de moyens qui permettent de le remplir avec les produits choisis ainsi que de moyens qui permettent de le fermer. Le poste de remplissage (2) comprend une structure de confinement (4), ou cloche, dont la forme permet de loger le sachet (3) au cours des opérations d'ouverture, de remplissage et de fermeture. Plus particulièrement, la cloche comprend préférablement un moyen pour aspirer l'air de l'intérieur de la cloche, au moins avant la fermeture du sachet, de façon à créer un niveau prédéterminé de vide qui facilite la fermeture du sachet et à limiter la détérioration du produit contenu grâce à l'élimination de l'oxygène.
