Definitions

  • the invention relates to a method and a device for sterilizing upright, open-topped and successively transported container, in particular carton / plastic composite packages for receiving beverages and / or food, wherein the container interior is first cleaned with a sterilizing agent and then dried with hot air.
  • ⁇ filling machines' are known in which continuously supplied containers such as cardboard / plastic composite packs filled with a certain amount of a given product and then sealed. In order for the product so filled to meet the shelf life requirements, the containers are cleaned before filling or even sterilized in aseptic filling to reliably kill the germs located inside the still empty container.
  • the filling machines have, in addition to the actual filling unit, a sterilization unit arranged upstream of this, with the containers, transported one behind the other and open at the top, being passed below the sterilizing unit.
  • the number of sterilizing nozzles arranged one behind the other and the amount of hot air supplied in addition must be matched to the container size, transport speed, etc. become. It is clear that when using a sterilizing agent such as
  • a disadvantage of the known devices is that the containers are moved transversely to the - substantially vertical - sterile air flow.
  • suction devices which are generally arranged below the containers, the adjacent containers are influenced by vortexes or vortex separations arising as a result of the movement, so that, in the worst case, unsterile air can enter the previously sterilized container.
  • the nozzles for supplying sterilizing agent and hot air are arranged in the vicinity, but always change their position relative to the container moved past the container interior, harmful turbulence and thus possible contamination can not be ruled out. This problem can not be taken into account by the fact that the container of the hot air nozzle and then the sterilizing nozzle are assigned pre-assigned. Due to the sequence of movements necessary here, subsequent contamination can not be completely excluded.
  • the invention is therefore based on the object, the aforementioned method and the method described in more detail above or the device used for sterilizing containers so and further, that Reliable sterilization and reliable removal of the sterilant can be ensured.
  • the sterilizing agent is passed through a tube nozzle ending above the container and the hot air through an annular gap nozzle arranged around the tube nozzle and wherein the movement of containers and nozzles takes place jointly and continuously.
  • the object is achieved in that the nozzle has an inner tube and at least one outer tube and that the tube nozzle formed by the inner tube preferably for sterilization with a
  • Sterilization agent and the annular gap formed by the inner tube and outer tube preferably for warming or drying is preferably provided with air.
  • the invention has thus recognized that by using a "double nozzle" both the required hot air and the sterilizing agent can be centrally introduced into a container so that reliable sterilization is always ensured. since there is no longer any relative movement between the container and the single nozzle arranged centrally above it.
  • the hot air is blown through the annular die, in contrast to the known from the prior art pipe nozzles not primarily the bottom, but more heated the upper portion of the packing wall.
  • the amount of sterilizing agent required for sterilizing a container is for example 450 ⁇ l / s for a packing volume of 11.
  • the volume flow (at room temperature) of the sterilizing agent is between 5 and 10, preferably 7.5 Nm 3 / h, and that of hot air in the range between 28 and 30 Nm 3 / h.
  • the time for preheating, sterilizing and drying is in each case 1 to 3 seconds, preferably 2 seconds. In this way it is possible to achieve a sterilization in continuously moving containers in a period of less than 6 seconds.
  • Hydrogen peroxide H 2 O 2
  • other chemical sterilants for the inventive method can be used.
  • the inner tube at the nozzle outlet is shorter than the outer tube.
  • the clear cross-sectional areas of inner tube and outer tube are the same size. It is readily apparent that, depending on the size of the container and the time available, different spray characteristics can be set by means of the parameters of the clear cross-sectional areas and the distance between the two tube ends in order to achieve optimal sterilization. In experiments, it has been found that the clear cross-sectional areas for each nozzle are between 150 and 300 mm 2 , preferably between 176 (pipe nozzle diameter: 15 mm) and 254 (pipe nozzle diameter: 18 mm).
  • a plurality of nozzles are arranged radially on a plurality of containers receiving sterilizer.
  • the treatment steps of preheating, sterilizing and drying can take place immediately after one another, wherein the position of the container to be sterilized does not change during the sterilization process to the nozzle arranged above it.
  • the system can be optimized via the wheel diameter or the number of container stations and nozzles arranged on the wheel, as well as the rotational speed, since the residence time of the containers to be sterilized on the sterilizing wheel can be as short as possible before the containers are subsequently transferred to a filling station or to a filling wheel be handed over.
  • FIG. 1 is a schematic perspective view of the position of a nozzle according to the invention to the underlying container
  • FIG. 2 shows a cross section through the nozzle outlet of a first embodiment of a nozzle according to the invention
  • Fig. 3 shows a cross section through the nozzle outlet of a second embodiment of a nozzle according to the invention.
  • Fig. 1 shows an upright, open-topped package P under a sterilizing nozzle 1, wherein the sterilizing nozzle 1 is arranged centrally above the package P and above it. Due to the simultaneous and uniform movement of the sterilizing nozzle 1 and the package P, the process steps of preheating, sterilizing and drying can take place in the shortest possible time in succession, without undesirable turbulence being caused by a relative movement.
  • FIGS. 2 and 3 show two different nozzle outlets.
  • a nozzle 1 is shown, in which an inner tube 2 and a concentrically arranged around outer tube 3 are provided, which are the same length at the nozzle exit.
  • the clear cross-sectional area of the inner tube 2 may be the same size as the clear cross-sectional area of the annular gap nozzle formed from the inner tube 2 and outer tube 3.
  • a nozzle 1 ' is shown, in which the inner tube 2' is shorter than the outer tube 3 is formed. Increasing the diameter of the outer tube 3, the temperature of the packing wall increases towards the top. By changing the nozzle geometry, an optimal adaptation to the pack P to be sterilized can be achieved.

Abstract

La présente invention concerne un procédé et un dispositif pour stériliser des récipients qui sont transportés les uns derrière les autres, en position verticale, leur ouverture dirigée vers le haut, en particulier des emballages composites carton/plastique qui servent à recevoir des boissons et/ou des aliments, l'intérieur du récipient étant tout d'abord nettoyé avec un agent de stérilisation puis séché avec de l'air chaud. Pour permettre une stérilisation efficace sans impliquer un déplacement relatif entre les buses et le récipient à stériliser, la buse (1, 1') du dispositif de l'invention présente un tube intérieur (2, 2') et au moins un tube extérieur (3), et la buse tubulaire formée par le tube intérieur (2, 2'), permet la stérilisation avec un agent de stérilisation, et la buse à espace annulaire formée par le tube intérieur (2, 2') et le tube extérieur (3), permet le chauffage ou le séchage avec de l'air.
