- the invention relates to a method according to the preamble of claim 1, to a system for performing this method according to the preamble of claim 9 and also to the use of a gas filter, in particular a membrane filter in a plant for processing, in particular packaging of oxygen-sensitive products according to the preamble of claim 15.
- this process gas is used for example to generate a protective or inert gas atmosphere in which the processing For example, the filling of the respective packaging with the product and the closing of the packaging done. Furthermore, it is also known to flush packaging before filling with the CO ⁇ gas used as the process gas. This rinsing serves to completely or almost completely remove the ambient air contained in the still unfilled packaging, and thus the oxygen contained in this air from the packaging, and to replace it with an oxygen-free process gas.
- the invention has for its object to avoid these disadvantages.
- a method according to claim 1 is formed.
- a plant for carrying out the method is the subject of claim 9.
- the use of a gas fractionator or gas filter, in particular a membrane filter is the subject of claim 15.
- oxygen-sensitive product is to be understood as meaning products of the most varied types and consistencies, including the inclusion or addition of oxygen in terms of their durability and / or quality and / or taste, etc., but also with regard to their usability and usefulness or effect are impaired.
- "Packaging" within the meaning of the invention are in particular bottles, tubes, cans, jars, buckets or similar containers, but also from flat material, for example, from multilayer flat material, for example by folding produced packaging, such as soft packaging, bags, etc.
- Oxygen-free or substantially oxygen-free process gas in the sense of the invention is a gas which contains at least one component obtained by fractionation of ambient or atmospheric air, which does not contain oxygen (O 2 , also O or O 3 ) or at most only such a small amount. contains negligible oxygen content, which does not lead to a significant and / or relevant impairment or damage to the respective product.
- the oxygen-free or substantially oxygen-free process gas then contains mainly nitrogen and possibly further constituents, such as small amounts of argon, carbon dioxide and water vapor.
- Fractionation of ambient or atmospheric air in the sense of the invention means the separation of the ambient or atmospheric air into its gas and vapor components by using at least one gas filter, preferably by using at least one membrane filter.
- ambient or atmospheric air includes, in addition to the ambient or atmospheric air mentioned, an oxygen-free or substantially oxygen-free process gas which is used repeatedly in a circulation process and is freed again from any occurring oxygen contaminants before each reuse.
- Fig. 1 in a schematic block or functional representation of a gas filter system for
- FIG. 2 in a simplified representation a section through a
- Container treatment machine in the form of a capping machine; 3 shows a view similar to FIG. 1 of a filter arrangement according to a further embodiment of the invention; 4 is a functional representation of a special embodiment of the gas or
- the filter system serves to fractionate the ambient air consisting of a mixture of different gas components into the individual gas and / or vapor constituents, which are provided separately at the outputs G1-Gx of the filter system 1, respectively.
- the filter system consists of a gas filter 2, in which the fractionation done by appropriate filter media.
- the filter media of the gas filter 2 are, for example, designed and arranged within one or more flow channels of the gas filter 2 such that only one gas component is obtained at each outlet.
- the gas filter 2 is preferably designed as a membrane filter, in which the individual filter media are formed, for example, by filter membranes which are permeable in each case only to the gas component assigned to the respective output G1-Gx.
- the gas filter 2 is preceded by a sterile filter 3, for example, via which the ambient air is supplied to the gas filter 2 and in which particles contained in the ambient air, such as dust, soot, etc. but also in particular germs and microorganisms of any kind, such as fungi, bacteria, viruses etc. are retained, so that the gas filter 2 only clean and sterile ambient air is supplied and therefore also at the outputs G1 - Gx clean and sterile gas components are available.
- a sterile filter 3 for example, via which the ambient air is supplied to the gas filter 2 and in which particles contained in the ambient air, such as dust, soot, etc. but also in particular germs and microorganisms of any kind, such as fungi, bacteria, viruses etc. are retained, so that the gas filter 2 only clean and sterile ambient air is supplied and therefore also at the outputs G1 - Gx clean and sterile gas components are available.
- the filter system 1 is intended for use in container treatment machines or systems, and in particular also for those systems which are suitable for processing, i. especially for filling oxygen-sensitive products.
- the filter unit 1 With the filter unit 1 it is now possible to obtain the components which are not harmful to the respective product to be processed and which are available at the outputs G1-Gx, i. For example, to use all components except the oxygen component (O, 02, 03) as the process gas for the plant 4 processing the product in question.
- the corresponding Gaskompone ⁇ ten the outputs G1 - Gx are then merged, for example, and passed to the system 4.
- the oxygen component produced at one or more outputs is e.g. derived in the environment or, for example, fed to a plant 5, in which using the oxygen ozone or an ozone-containing air and / or gas mixture, for. generated for cleaning or sterilization purposes.
- FIG. 2 shows a capping machine 6 of circumferential design for closing bottles 7 filled with the oxygen-sensitive product.
- the bottles 7 are supplied to a rotor 8 which is driven in rotation around a vertical machine axis VA such that each bottle is arranged upright on a bottle plate 9 of the rotor 8 below a closing tool 10 also provided on the rotor, which is used to close the bottles 7 with crown corks or other closures is formed.
- the bottles 7 are each accommodated in a space 12 formed by an enclosure 11 and separated from the environment, to which the process gas produced by the gas filter 2 is supplied via connections 13 in such a way that this process gas flows through the interior 12 from top to bottom and exits in the lower region of the space 12 into the atmosphere.
- the entire inner space 12 is filled and flowed through by the oxygen-free process gas.
- the mouth openings of the bottles 7 are intensively flowed around by this process gas.
- this rinsing can likewise be carried out with the oxygen-free process gas supplied by the gas filter 2.
- the oxygen-free process gas supplied by the gas filter 2 can also be used for pressure-tempering.
- FIG. 3 shows, in a depiction as in FIG. 1, a filter system 1a that differs essentially from the filter system only in that the sterile filter 3 is connected downstream of the gas filter 2 for fractionating the ambient air, in such a way that only the process gas in the Appendix 4 used fractionated air components are treated in the sterile filter, whereby, inter alia the volume of gas to be processed in the sterile filter can be significantly reduced.
- FIG. 4 shows the structure of a gas filter 2a in a greatly simplified functional representation.
- the interior 14 of this gas filter is supplied via an inlet 15 ambient air, for example, previously purified in the sterile filter 3 ambient air, namely. over a fan.
- a plurality of filter membranes 16 are successively provided in the flow direction. These are selected with regard to their filtering effect such that a gas component is retained on each filter membrane 16 and the remaining gas components are passed on. The retained gas components are then available at the outputs G1-Gx associated with the filter membranes.
- a separate output GI-Gx is provided for each gas component formed by fractionation from the ambient air.
- the respective gas filter in such a way that it has a common output for at least two oxygen-free components.
- the gas filter is designed so that the product supplied by this filter and processed during the processing of the oxygen-sensitive product, e.g. used in filling this product and / or in treating the used packaging process gas is free of oxygen.
- the scope of the present invention also extends to a plant for bottling beverages, in which at least one closing machine and / or a filling machine and / or the Be Strukturertra ⁇ sportwege between these machines from the ambient air are at least partially protected and at least partially with oxygen-free or substantially oxygen-free process gas are applied.
- the technical teaching of the present invention inter alia, by the significant reduction in the cost of the supply of an oxygen-free or substantially oxygen-free process gas to use this to a much greater extent than before, resulting in a further reduction of the oxygen content in the packaged and / or bottled products.
