Definitions
- the invention relates to a method for filling containers with a liquid, where the liquid is poured into the container and then the container is closed, after filling the liquid and before closing of the container at least one jet of inert gas onto the surface of the liquid is directed that the inert gas jet penetrates the liquid and the liquid brings to frothing, causing the above the liquid surface in the container existing ambient air is displaced, and a device for performing of the procedure.
- High pressure water jet injection is usually used. This is done after filling the bottles and before closing the bottles Water is injected into the bottles under high pressure, causing rapid foaming the carbonized liquid is effected. The one in the headspace of the bottles existing air is displaced from the bottles by the foaming liquid.
- this method only works with carbonized liquids.
- US-A-2 372 457 describes a method of filling containers with a Liquid, the liquid being poured into the container and then the Container is closed, being after filling the liquid and before Seal the container with an inert gas jet on the surface of the liquid is directed that the inert gas jet penetrates the liquid and the liquid brings to frothing, causing the above the liquid surface in the container ambient air is displaced.
- the present invention has for its object a method of the beginning mentioned type and to design a device for carrying out the method, that the greatest possible distance from gaseous oxygen is reached from the headspace of the container.
- this object is achieved in that the inert gas jet is enveloped by an inert gas such that the friction of the inert gas jet is reduced with the ambient air.
- nitrogen is the inert gas or provided carbon dioxide. It is also conceivable e.g. the use of Noble gases.
- the inert gas jet is preferably made of gaseous nitrogen and / or gaseous carbon dioxide formed. In addition or as an alternative to the gaseous one
- the inert gas jet can also liquid and nitrogen and / or gaseous carbon dioxide Have nitrogen and / or liquid carbon dioxide.
- the inert gas jet is adjusted so that the liquid exactly up to the top of the container foams. In this way, an overexposure the liquid and related cleaning work can be avoided.
- inert gas jets are closely bundled, so that due to the intensity of the bundled beam even with larger containers and liquid surfaces a foaming of the liquid up to the edge of the container and thus displacing the oxygen in the container head space is effected.
- the intensity of Inert gas jet can be precisely controlled with the method according to the invention controlled foaming of the liquid in the container, so that a Safe displacement of the oxygen from the container is effected without the disadvantages having to put up with overflowing of the container.
- the invention further relates to a device for filling containers with a Liquid with a container filling device and a container closing device and a conveyor for transporting the containers from the container filling device to the container closing device, wherein between the container filling device and the container closing device a device for generating at least an inert gas jet is provided, which is designed such that the inert gas jet can be aligned to the liquid surface in the container and is adjustable so that it is in the liquid penetrates and causes the liquid to foam, causing the Ambient air above the liquid surface in the container is displaced becomes.
- the device for Generation of the inert gas jet has a double tube consisting of an inner tube and there is an outer tube surrounding the inner tube, the inner tube with an inert gas under high pressure can be acted upon, while the External tube can be acted upon with an inert gas under low pressure.
- the device for generating the inert gas jet is preferably adjustable in such a way that that the inert gas jet the liquid exactly up to the top of the container Foaming brings.
- the outer tube is preferably arranged concentrically with the inner tube. Both that The inner tube and the outer tube are in an inert gas supply device Connection, however, the inner tube with a high pressure, e.g. 1.5 bar to 10 bar, inert gas and the outer tube with a low pressure, e.g. 1.1 bar to 3 bar, standing inert gas can be charged.
- a high pressure e.g. 1.5 bar to 10 bar
- inert gas and the outer tube with a low pressure e.g. 1.1 bar to 3 bar
- standing inert gas can be charged.
- Active beam preferably with a cross section of about 0.3 to about 1 mm, the penetrates into the liquid in the container and causes it to foam.
- the outer tube fulfills the function of a cladding tube, which is from Inert gas flowing out of the outer tube the active jet emerging from the inner tube envelops and thus reduces the friction of the active beam with the ambient air, thereby prevents the active beam from tearing open after it emerges from the inner tube becomes.
- the invention is suitable for filling all conceivable liquids into containers, whereby liquids in the sense of the present invention mean all media are that can be made to foam.
- the invention for filling liquid foods, e.g. Beer, in cans or bottles intended.
- the application of the invention is not only carbonized Limited liquids.
- the oxygen content in the closed containers can be obtained on the liquid can be reduced to below 0.1 mg oxygen per liter. Thereby oxidation processes in the liquids can be reliably prevented, so that the quality and shelf life of liquids, especially liquid foods is increased.
- the invention is used with particular advantage in beer bottling. Especially with Beer is the requirement to get a hygienically perfect and durable product, particularly high. Because the addition of preservatives to beer is special is frowned upon (German Purity Law), the shelf life of the beer must other way. With the present invention, a Possibility created in an economical way without the addition of preservatives the shelf life of beverages significantly increase and at the same time the to significantly improve hygienic conditions during the filling process.
- the present exemplary embodiment relates to a beverage filling device for Filling beer into cans.
- a facility for bottling beer would be constructed similarly.
- the beverage cans 1 are filled with beer 3 in a can filling machine 2.
- the filled beverage cans 1 are then on a transport path 4 in the direction of travel 5 transported to a can sealing machine 6.
- On the way from the Can filling machine 2 for can closing machine 6 are those filled with beer Beverage cans 1 from a beam generating device 7 with a bundled one Inert gas jet 8 is applied.
- the beam generating device 7 is located in the Figure not shown inert gas supply device, e.g. a liquid nitrogen tank, in connection.
- the beam generating device 7 has a double tube 9 which consists of an inner tube 10 and an outer tube 11.
- In the inner tube 10 is a tightly bundled inert gas jet with a diameter of about 0.5 mm, the is under high pressure of approx.
- This tightly focused inert gas jet serves as Active jet that enters the liquid contained in the container 1. From the outer tube 11 emerges an inert gas, which is under a low pressure of approx wrapped concentrically. This will reduce the friction of the active beam after leaving of the inner tube 10 is reduced with the ambient air, causing tearing of the active beam is prevented after exiting the inner tube 10.
- the one in the Inert gas jet 8 which has penetrated liquid brings the liquid into the beverage can 1 for foaming, which displaces the air in the beverage can 1 becomes.
- the inert gas jet 8 is set so that the liquid exactly up to the top Foam edge of the beverage can 1. After closing the beverage can 1 using the sealing machine 6 is in the beverage can 1 only the filled Beer and inert gas.
