1. Technical Field
The present application relates to a method for the processing, in one possible embodiment for the packaging, of products in packaging using an oxygen-free or essentially oxygen-free process gas in a plant for the performance of the method, as well as to the use of a gas filter, in one possible embodiment a membrane filter, in a plant for the processing, in one possible embodiment the packaging of oxygen-sensitive products.
2. Background Information
Background information is for informational purposes only and does not necessarily admit that subsequently mentioned information and publications are prior art.
One problem that is encountered in the packaging of many products as well as many beverages, the shelf life and/or quality and/or taste of such products can be seriously and adversely affected by air or by the oxygen (O, O2, O3) in the air. A contamination with oxygen can occur, for example, during packaging or during the filling of the packaging with the product in question and/or after the packaging and before and/or during the closing or capping of the packaging that is being used.
To resolve this problem, some processing of such oxygen-sensitive products is performed using a process gas, which is generally formed by CO2, whereby this process gas is used, for example, for the production of a protective or cover gas atmosphere in which the processing is performed, such as, for example, the filling of the individual packages with the product and the closing of the packages. Some packaging is also flushed prior to filling with the CO2 gas that is used as the process gas. The purpose of this flushing is to remove all or almost all of the ambient air which is inside the empty packaging, and thus to remove all or almost all of this oxygen from the packaging and replace it with a process gas that comprises pure oxygen.
One disadvantage of these methods described above is that the inert gas that is used as a process gas is a significant cost factor. One of the results is that the inert gas can be used in some plants in a few, highly-critical, targeted areas.
An object of the present application is to eliminate, restrict, and/or minimize these disadvantages. The present application teaches that this object can be accomplished by a method for the processing, in one possible embodiment for the packaging, of products in packaging using an oxygen-free or essentially oxygen-free process gas in a plant. The process gas is obtained in at least one gas filter of the plant by fractionation of atmospheric air. Another object of the present application may be a plant for the processing, in one possible embodiment for the packaging of products in packaging using an oxygen-free or essentially oxygen-free process gas in a plant. The plant has at least one gas filter for the production of the process gas by fractionation of atmospheric air. The use of a gas fractionator or gas filter, in one possible embodiment of a membrane filter, is the object of a gas filter, in one possible embodiment a membrane filter, which may be used in plants for the processing and/or for the packaging of oxygen-sensitive products for the production of an oxygen-free or essentially oxygen-free process gas.
The term “oxygen-sensitive product” as used in the context of this application includes a wide variety of products having a wide variety of consistencies, which are adversely affected by the inclusion or of contamination with oxygen in terms of their shelf life and/or their quality and/or their taste, and/or in terms of their utility, applicability and/or effect.
The term “packaging” as used in the context of the present application includes but is not limited to bottles, tubes, cans, jars, buckets, pails, tins or similar containers, as well as packaging produced from flat material, e.g. laminated flat material, by folding, such as soft packages, bags, etc.
The term “oxygen-free or essentially oxygen-free process gas” as used in the context of the present application is a gas that comprises at least one component that is obtained by the fractionation of ambient or atmospheric air, which comprises no oxygen (O2 or O or O3) and/or comprises a percentage of oxygen so low as to be negligible, which does not lead to a significant and/or relevant adverse effect or damage to the respective product. The oxygen-free or essentially oxygen-free process gas then comprises primarily nitrogen or potentially additional components such as small quantities of argon, carbon dioxide and water vapor.
“Fractionation of ambient or atmospheric air” as used in the context of the present application means the separation of the ambient or atmospheric air into its gas and vapor components by the use of at least one gas filter, in one possible embodiment by the use of at least one membrane filter.
“Ambient or atmospheric air” as used in the context of the present application means, in addition to the obvious ambient or atmospheric air, an oxygen-free or essentially oxygen-free process gas which is used multiple times in a circulation method and which is freed of any oxygen contamination that may occur repeatedly before every re-use.
Developments, embodiments and potential application of the present application are described in greater detail below on the basis of possible embodiments and with reference to the accompanying figures. The features of the present application described in the text and/or illustrated in the drawings, individually or in any possible combinations, may be an object of the present application.
The above-discussed embodiments of the present invention will be described further herein below. When the word “invention” or “embodiment of the invention” is used in this specification, the word “invention” or “embodiment of the invention” includes “inventions” or “embodiments of the invention”, that is the plural of “invention” or “embodiment of the invention”. By stating “invention” or “embodiment of the invention”, the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.
The present application is explained in greater detail below with reference to the possible embodiments illustrated in the accompanying figures, in which:
The filter system, which is designated 1 in general in
The filter system 1 is designed for use in container handling machines or plants, and is thereby used in one possible embodiment also for plants that are used for the processing, i.e. in one possible embodiments for the bottling or packaging of oxygen-sensitive products.
With the filter system 1, it is now possible to use the components that are made available at the outputs G1-Gx and are harmless for the product being processed, in other words, for example, the components with the exception of the oxygen components (O, O2, O3) as process gas for the plant 4 that processes the product in question. The gas components corresponding to the outlets G1-Gx are then combined, for example, and transported to the plant 4. The oxygen components that are available at one and/or more of the outputs are discharged into the atmosphere, for example, or transported to a system 5 in which ozone and or a mixture of air and/or gas that comprises ozone is generated for cleaning and sterilization purposes, for example.
The oxygen-free process gas supplied by the gas filter 2 is used in the plant 4, for example, as a cover gas during the filling of the containers with the oxygen-sensitive product or liquid and during the closing or capping of these containers. One example of this process is illustrated in
In a similar fashion, during the filling with the oxygen-sensitive product, i.e. in the capping machine 6 that is upstream in the plant 4, and on the conveyor line between the filling machine and the capping machine 6, the bottles 7 are located in the cover gas atmosphere formed by the process gas of the gas filter 2.
If, during the filling of the bottles 7 before the introduction of the liquid, the interior of the individual bottle is flushed to displace air or the corresponding oxygen component, this flushing can also be done with the oxygen-free process gas supplied from the gas filter 2. For a non-carbonated beverage which is being bottled in the container or bottle 7 pressurized with a gas, the oxygen-free process gas delivered from the gas filter 2 can also be used for the pressurization.
The present application was described above on the basis of possible embodiments. It goes without saying that numerous modifications and variations can be made without thereby going beyond the teaching of the present application.
In the above description, it was assumed that a separate output G1-Gx is provided for each gas component separated from the atmospheric air by fractionation. Basically, however, it is also possible to realize the individual gas filter so that it has a common output for at least two oxygen-free components. In each case, however, the gas filter must or may be realized so that the product supplied by this filter, e.g. the process gas used in the processing of the oxygen-sensitive product, e.g. during the bottling of this product and/or during the treatment of the packaging used, is oxygen-free.
The teaching of the present application also includes a plant for the bottling of beverages in which at least one capping machine and/or one filling machine and/or the container transport routes between these machines are at least partly protected from atmospheric air and are supplied at least partly with oxygen-free or essentially oxygen-free process gas.
The present application teaches, among other things, that the costs for the supply of an oxygen-free or essentially oxygen-free process gas can be significantly reduced, that said process gas can be used to a much greater degree, which makes possible a further reduction of the oxygen content in the packaged and/or bottled products.
In a method for the processing, in one possible embodiment for the packaging of products in packaging, using an oxygen-free or essentially oxygen-free process gas in a plant, the process gas is obtained in at least one gas filter of this plant by fractionation of atmospheric air.
One feature or aspect of an embodiment is believed at the time of the filing of this patent application to possibly reside broadly in a method for the processing, in one possible embodiment for the packaging, of products in packaging using an oxygen-free or essentially oxygen-free process gas in a plant 4, wherein that the process gas is obtained in at least one gas filter 2, 2a of the plant 4 by fractionation of atmospheric air.
