Definitions

  • the invention relates to a packaging machine line for producing deep-drawn packaging troughs from a plastic film with a device for loading the packaging with a gas desired within the sealed packaging, for example an inert gas or air enriched with oxygen.
  • a gas desired within the sealed packaging for example an inert gas or air enriched with oxygen.
  • the film which is deep-drawn to form packaging troughs is cooled, then filled, optionally degassed or charged with an inert gas and finally sealed.
  • a packaging machine line with at least one deep-drawing station and at least one filling station has been created, in which between the above-mentioned stations a device for applying a gaseous or volatile substance to the deep-drawn packaging troughs, which at atmospheric pressure has a boiling or sublimation point ⁇ 10 ° C and a temperature ⁇ 3 ° C is arranged.
  • a device for applying a gaseous or volatile substance to the deep-drawn packaging troughs which at atmospheric pressure has a boiling or sublimation point ⁇ 10 ° C and a temperature ⁇ 3 ° C is arranged.
  • the gaseous or volatile substance can be any substance which is gaseous or vaporizes under atmospheric pressure and a temperature ⁇ 1 ° C and thus at least partially forms the atmosphere within the sealed package.
  • These can be inert gases such as nitrogen or carbon dioxide, or oxygen or air enriched with oxygen.
  • the substances can be added in their liquid, solid and / or gaseous form and then evaporate, evaporate and / or sublime within the packaging. Sublimation means the transition from the solid to the gas phase. For example, dry ice or liquid nitrogen can be added to the packaging trough, which becomes gaseous there.
  • the gaseous or volatile substances depends on the requirements of the contents stored in the packaging and is not subject to any restrictions on the part of the plant technology used.
  • the gaseous or volatile substance is selected such that the gaseous or volatile substance is only present in the gaseous phase within the packaging under normal conditions when the packaging is filled with filling material.
  • CO 2 and / or N 2 with a temperature of ⁇ -50 ° C., preferably ⁇ -100 ° C., very particularly preferably ⁇ - 150 ° C. is very particularly preferably used.
  • the deep-drawn packaging troughs are charged with the gaseous or volatile substance in the packaging machine lines according to the invention in such a way that at least a first cooling of the film heated by the forming process and / or an upstream heating process occurs and that the packaging troughs undergo a first gas exchange, i.e. a displacement of the in the Packaging trays present air.
  • Packaging trays can be at least partially cooled and optionally partially rendered inert in a single device. In most cases, the packaging troughs can be cooled very quickly below a maximum temperature, for example 2 ° C., required for further processing, for example filling. Often, a strong cooling of the surfaces alone is sufficient to keep the packaging below the permissible maximum temperature, at least during the entire packaging process, because the heat stored in the film, which is transported towards the cooled surface over time, is not sufficient around the surface to raise above the permissible maximum temperature.
  • the packaging trays are at least partially sterilized.
  • any gas exchange that may occur after the packaging trough has been filled with packaging material can be completely eliminated or at least significantly shortened because at least the gas is below the Packaged goods do not have to be replaced or only to a minor extent.
  • Means and devices for applying a gaseous or volatile substance to a packaging tray are known to the person skilled in the art.
  • these means consist of supply lines which open into outlet openings above each individual packaging tray.
  • these means are arranged above the packaging trays, so that the gaseous or volatile substance can be passed directly into the packaging trays.
  • the outlet openings have slot nozzles from which the gaseous or volatile substance enters the packaging troughs.
  • simple and intensive means ensure that the packaging troughs are acted upon more intensely and uniformly over their entire length and / or width.
  • the means are designed in such a way that the gaseous or volatile substance can be applied to at least two packaging trays at the same time. The throughput of a packaging machine line according to the invention is increased in a particularly simple manner.
  • the throughput takes place in cycles, so that at the same time a plurality, for example six, packaging troughs are heated, deep-drawn and charged with the gaseous or volatile substance.
  • a plurality for example six, packaging troughs are heated, deep-drawn and charged with the gaseous or volatile substance.
  • the amount of volatile material introduced depends in a manner known to the person skilled in the art on the desired result with regard to the cooling of the heated material and the amount of material desired within the packaging tray.
  • the packaging trays to which the gaseous or volatile substance is applied are then covered directly, as a result of which an almost unchanged gas atmosphere remains inside the packaging tray in a simple manner.
  • this cover can be provided by a cover plate, which is preferably carried out between the cooling and the filling and / or between the filling and the sealing of the packaging troughs.
  • the packaging machine line also has means for collecting and, if necessary, returning the material which has escaped, for example evaporated or evaporated, after the packaging trays have been loaded.
  • the gases collected in this way can also be used for gas exchange in the packaging tray before it is sealed.
  • FIG. 1 shows a sectional side view of part of a packaging machine line according to the invention
  • Figure 2 shows a plan view of the packaging machine line according to. figure
  • FIG. 1 shows a sectional side view of part of a packaging machine line 2 according to the invention.
  • the packaging machine line 2 comprises a heating system 8, a deep-drawing station 6 and a device 1 for loading the packaging troughs 4 with a gaseous or volatile substance.
  • FIG. 2 shows a top view of packaging machine line 2.
  • the film 3, the edges of which are shown with dashed lines 9, runs in the direction of the arrow 10 through the packaging machine line 2.
  • the packaging trays 4 become part of the device 1 a gaseous or volatile substance.
  • the device 1 has means 7 through which the gaseous or volatile substance is passed from a supply (not shown) to the individual packaging trays.
  • the means 7 end in the middle above each individual packaging trough 4 and open into schematically indicated slot nozzles 11, the longitudinal alignment of which is arranged perpendicular to the longitudinal alignment of the rectangular packaging troughs 4.
  • the slot nozzles 11 are particularly favorable when the slot nozzles 11 are arranged parallel to the longitudinal orientation of the packaging trays and have a length which essentially corresponds to the length of the packaging trays 4.
