Definitions

  • the invention relates to a method and a device for tapping beer, in particular wheat beer, into drinking vessels, in which the beer flows under gas pressure from a tank, in particular a beer keg, the tank initially being at least previously at a gas pressure in the tank preloaded intermediate container is connected, the volume of which corresponds at least to that of a drinking vessel, whereupon the intermediate container relaxes and the beer is diverted from the tank for the purpose of filling the intermediate container and finally an outlet on the intermediate container is opened for filling the drinking vessel.
  • each empty bottle is first prestressed with compressed gas, this prestressing being carried out in two stages.
  • the bottle receives a filling from a separate source of pressurized gas, which causes the pressure in the bottle to rise to such an extent that it is slightly below the pressure in the tank from which the beer is withdrawn.
  • the pressure in the bottle then becomes the pressure in the tank adapted in that a corresponding connection is made for the overflow of compressed gas from the tank into the bottle.
  • the pressure in the bottle is then the same as in the tank.
  • DE-AS 26 58 667 provides no reference to the tapping of beer into drinking vessels.
  • the problem arises that the beer flowing from a tap, which is under gas pressure in the tank, is completely relaxed immediately behind the tap, whereby the compressed gas dissolved in the beer, especially carbonic acid, escapes suddenly in the form of bubbles, which is a strong foaming of the beer shows.
  • white beer which is usually under a particularly high carbon dioxide pressure, in which the carbon dioxide pressure is normally 2.5 to 3 bar.
  • This foaming leads to the individual drinking vessels being successively filled with smaller amounts than the full volume of the drinking vessel. In restaurants, this results in a considerable delay in serving.
  • a device for tapping carbonated liquids, in particular beer is known, with which significant losses of carbon dioxide are to be avoided during the movement of the liquid.
  • This device essentially consists of an intermediate container connected to a beer keg, the volume of which corresponds at least to that of a drinking vessel and from which the beer is tapped into the drinking vessel after it has been filled.
  • the redirection of the beer from the beer keg to the intermediate container takes place in such a way that the intermediate container is initially pretensioned to at least the gas pressure in the beer keg, whereupon the intermediate container relaxes and the beer is redirected from the beer keg to fill the intermediate container.
  • the one in the redirection of the beer from the beer keg into the intermediate Relaxation of the intermediate container takes place in such a way that a whistle valve attached to the intermediate container is opened, but the connection of the intermediate container to a compressed air source, which provided for the generation of the gas pressure in the intermediate container before this beer diversion, is maintained.
  • the compressed air contained in the intermediate container whistles, while simultaneously loading the compressed air source, which is unnecessary consumption for it.
  • the whistling amounts to a rapid and extensive reduction in pressure, that is to say a considerable pressure level, which promotes undesirable foam formation in the intermediate container. If the intermediate container is then filled in this way, the supply of compressed air is blocked and a tap is opened. This also results in a pressure level, namely due to the shutoff of the supply of compressed air, which in turn favors the foaming of the beer in the intermediate container.
  • the invention has for its object to accelerate the pouring of beer, in particular wheat beer, and thereby reduce the foam development desired per se so that a rapid filling of the drinking vessel is possible in one go with sufficient foam formation.
  • this is done in that when the beer is diverted into the intermediate container, a pressure close to the gas pressure in the tank is maintained in it, which pressure is reduced substantially to atmospheric pressure by gently lowering the pressure before tapping into the drinking vessel .
  • the operating phase from the start of the redirection of the beer into the intermediate container until the beer is tapped into a drinking vessel is thus broken down into two special process steps.
  • air is used as the medium for the pressure preload in the intermediate container, it flows into the intermediate container from the outside when the drinking vessel is filled a, either on the way in which the gentle pressure reduction in the intermediate container has previously taken place, or, if the latter way the air cannot flow into the intermediate container quickly enough, via a separately opened inlet on the intermediate container.
  • the device for carrying out the method is based on a tank connected to a compressed gas source.
  • This source of compressed gas is usually a carbon dioxide bottle.
  • This device is characterized in that the intermediate container is connected to the tank via a pipeline provided with a valve, which is provided with valves for the supply of compressed gas, for the throttled discharge of the pressurized gas and the introduction of air, and which is also on its underside has a nozzle.
  • the device can also be designed so that the intermediate container contains a separating film made of resilient, tight-fitting material for dividing its interior into two container parts, with the pipe connected to the tank and a dispensing valve on one container part and valves for the other container part Supply and discharge of a print medium are connected.
  • a separating film made of resilient, tight-fitting material for dividing its interior into two container parts, with the pipe connected to the tank and a dispensing valve on one container part and valves for the other container part Supply and discharge of a print medium are connected.
  • the pressure medium introduced into the intermediate container does not come into contact with the beer contained in the intermediate container can occur so that in addition to gaseous pressure media, liquid pressure media can also be used.
  • the filling process for the intermediate container and the filling of the drinking vessel can be controlled in such a way that the intermediate container is successively filled largely without foam, whereupon a drinking vessel is then filled from the intermediate container and so on.
  • the volume of the intermediate container can be matched to that of a drinking vessel. In this case, the intermediate container must also be filled before each drinking vessel is filled.
  • Fig. 1 shows the barrel 1 serving as a tank, which can be filled with wheat beer in the illustrated embodiment.
  • the connecting piece 2 leading into the barrel 1 is connected on the one hand via the inlet 3 with shut-off valve 4 and the pressure hose 5 to the carbon dioxide bottle 6 and on the other hand via the outlet 7 with shut-off valve 8 and the beer hose 9 to the inlet 10 of the intermediate container 11.
  • the carbonic acid contained in the carbon dioxide bottle 6 reaches the outside via the pressure reducer 12, since there is normally a pressure of about 110 bar in the carbon dioxide bottle 6, whereas only one of about 3 bar is required for the carbon dioxide pressure in the barrel 1 if it is filled with wheat beer.
  • the pressure hose 5 is connected to the pressure reducer 12 via the shut-off valve 13.
  • carbonic acid is introduced into the keg 1 by opening the shut-off valves 13 and 4 via the pressure hose 5 and the inlet 3 in a known manner, which fills the cavity contained in the keg 1 above the beer level and because of it Presses beer over the pipe 14 reaching to its bottom into the barrel 1.
  • the tube 14 leads directly to the outlet 7, so that when the shut-off valve 8 is opened, beer is pressed into the beer hose 9 and thus flows into the intermediate container 11.
  • the intermediate container 11 was provided with a carbonated filling prior to this operation, via the broken line pressure line 15 via the shut-off valve 16 receives carbon dioxide from the pressure reducing valve 12 and supplies it to the surge tank 11 via the check valve 20 on the connecting piece 1. 7 With regard to the design of the connecting piece 17, reference is made to FIG. The same gas pressure then prevails in the intermediate container 11 as in the barrel 1 above its liquid gel.
  • the shut-off valve 20 for the supply of carbonic acid is closed and the shut-off valve 18 is opened, to which the throttle 19 is connected, so that now the Intermediate container 11 gas can slowly escape through the shut-off valve 18 and the throttle 19.
  • the beer 34 flowing into the intermediate container 11 is always kept under a pressure which comes very close to the carbon dioxide pressure in the barrel 1, since gas escaping from the intermediate container 11 immediately in terms of its volume a corresponding volume of beer is replaced.
  • the result of this is that practically no carbon dioxide in the form of bubbles can escape from the beer 34 during this process, so that, above all, the interior of the intermediate container 11 remains practically foam-free.
  • the filling of the intermediate container 11 can be observed on its sight glass 21.
  • the shut-off valve 22 inserted in the inlet 10 is closed, whereby the filling process of the intermediate container 11 is ended.
  • the shut-off valve 18 is closed at the same time, so that the carbonic acid pressure in the intermediate container 11 is maintained, which practically corresponds to that in the barrel 1.
  • the beer 34 contained in the intermediate container 11 can now be tapped into a drinking vessel, in particular a beer glass 23, for which purpose the shut-off valve 26 is slowly opened first, which results in a gentle pressure reduction in the interior of the intermediate container 11.
  • the carbon dioxide contained in the intermediate container 11 escapes via the shut-off valve 26 and the throttle 27, the speed of the gas escaping in this way slowly increasing.
  • the carbonic acid dissolved in the beer 34 is therefore not stimulated to free itself from its solution in the beer 34 by the escape of gas bubbles, which would be the case if the pressure acting on the beer 34 were suddenly reduced.
  • this gradual reduction in pressure in the intermediate container 11 there is practically no foaming.
  • the shut-off valve 24 contained in the outlet pipe 25 is opened so that the beer 34 contained in the intermediate container 11 can now flow under the action of gravity into a drinking vessel under the outlet pipe 25, in particular into the beer glass 23 shown in FIG. 1. Due to the corresponding filling of the intermediate container 11 beforehand, the beer glass 23 is completely filled, the beer 34 only foaming in the beer glass 23 to the extent necessary for an appealing impression of a fully poured beer glass. During this outflow of beer 34 from the intermediate container 11, the volume which increases above its liquid level is filled by air which flows in from the outside through the throttle 27 and the still open shut-off valve 26 via the connecting piece 17 into the interior of the intermediate container 11.
  • the inflow speed is regulated by the throttle 27, which can be adjusted in a known manner so that the desired outflow speed results in the outlet pipe 25.
  • the throttle 27 can of course also be used to allow the previous outflow of carbonic acid from the intermediate container 11 in the sense of a gentle pressure drop in the intermediate container 11.
  • the illustrated construction of the intermediate container 11 comprises the lid 28 which is fastened to the flange 30 by means of the screws 29.
  • the seal between the cover 28 and the flange 30 takes place via the O-ring 31 placed in between.
  • the manometer 32 is attached to the cover 28 and can be used to read the pressure prevailing in the intermediate container 11 at any time.
  • the connecting piece 17 contains the shut-off valve 18 with throttle 19 for discharging the pressure in the intermediate container 11 when it is filled and the shut-off valve 26 with throttle 27 for slow relaxation the carbon dioxide when the intermediate container 11 is filled and for sucking in air when the beer 34 contained in the intermediate container 11 flows into a drinking vessel.
  • the shut-off valves 18 and 26 with their connected throttles 19 and 27 can be combined with one another, since they are only to be designed for the passage of gas, although the throttles each have a different throttling function.
  • the throttle In the case of a combination of the above-mentioned organs to form a shut-off valve with a connected throttle, it is only necessary to ensure that the throttle has to allow a gently rising release of the pressurized carbon dioxide from the intermediate container 11 and a suction of air, the latter with regard to the flow rate is to be adapted to the desired speed of filling a drinking vessel.
  • the throttle must have a different throttling effect depending on the direction of flow of the gas, which can be achieved using known means.
  • direction-sensitive valves can be provided which, depending on the direction of the flow, are connected to corresponding throttle openings.
  • the throttle 27 adjustable in such a way that, depending on the number of beers, it allows air to flow into the intermediate container 11 at different speeds. Is it a type of beer that does not tend to foam as much as wheat beer, e.g. light beer (full beer), the flow velocity of the air through the throttle 27 can be increased.
  • the float plate 33 is still drawn, which floats on the liquid level of the beer 34 contained in the intermediate container 11 .
  • It is a plate that shows the cross section of the interior of the intermediate container 11 essentially fills. It consists of a durable, especially acid-proof plastic. But it can also consist of a tight sleeve made of stainless steel, so that it has swimming properties.
  • the intermediate container 11 and the lid 28 are also made of stainless steel.
  • the float plate 33 has a particular effect on relaxing the carbon dioxide contained in the intermediate container 11 as a result of opening the shut-off valve 26. The tendency of the carbon dioxide dissolved in the beer to emerge in the form of gas bubbles from the beer has the greatest effect during this relaxation process.
  • the float plate 33 resting on the liquid level helps to slow down the relaxation acting on the 3ier 34 contained in the intermediate container 11, so that there is a particularly smooth transition from the tensioned to the relaxed state.
  • the intermediate container 11 is pressurized with carbon dioxide which is removed from the carbon dioxide bottle 6 before it is filled with beer 34.
  • a separate carbon dioxide filling is therefore required for each filling process of the intermediate container 11, which leads to a corresponding consumption of carbon dioxide.
  • This carbon dioxide consumption can be saved in that compressed air is used to pretension the intermediate container 11 before it is filled.
  • a corresponding compressed air source in the form of the compressor 34 is shown in FIG. 1.
  • the compressor 39 delivers compressed air via the pressure reducer 35 and the shut-off valve 36 to the compressed air hose 37 into which the air filter 38 is switched on.
  • the air filter 38 ensures that no contaminants can be passed on.
  • the compressed air then reaches the connecting piece 17, specifically here to the shut-off valve 20 (see FIG.
  • the float plate 33 has a particularly favorable effect. It practically completely prevents contact between the air contained in the intermediate container 11 and the beer that has flowed in. However, this is only of importance if beer is stored in the intermediate container 11 for a long time without being filled into a drinking vessel. Normally, however, the intermediate container 11 only serves to be filled step by step and then used to pour beer into a drinking vessel.
  • the intermediate container 11 can be dimensioned one after the other both for filling one or more drinking vessels.
  • the size of the intermediate container 11 should, however, only be dimensioned such that it is emptied again in rapid succession after it has been filled. Larger intermediate containers can thus be used at taps with a large beer throughput, whereas in cases in which the filling of the intermediate container 11 and the subsequent pouring into a drinking vessel is possible in succession without undue delay, an intermediate container with a size equivalent to the volume of one is expediently used Drinking vessel corresponds.
  • the intermediate container shown in FIG. 3 is basically constructed in the same way as the intermediate container according to FIG. 2, the same reference numerals being used for the same components. Differences be 2 insofar as the outlet pipe 25 used for tapping the beer according to FIG. 3 protrudes laterally from the intermediate container 11 and a pressure switch 36 is provided instead of the manometer 32 according to FIG. 2 in the arrangement according to FIG. 3 which serves to generate a signal for the automatic process control depending on the pressure prevailing in the intermediate container 11, namely when the pressure prevailing in the barrel 1 (see FIG. 1) is reached during the pretensioning of the intermediate container 11.
  • the release film 33 which is clamped by means of the O-ring 31 so that there are two separate container parts in the intermediate container 11, namely the lower container part 34, which is filled by the beer, and the upper Container part 35, which contains the pressure medium, in particular air.
  • the pressure exerted by the printing medium on the separating film 33 is indicated by the arrow shown.
  • the separating film consists of a tight, resilient material, for example polyethylene.
  • the shut-off valve 18 can be used to both inflow and let out pressure medium, which is indicated by the relevant opposite arrows. Which type of shut-off valves 18, 26 or how many are used depends on how the speeds in the pressure release are to be set in each case.
  • the separating film 33 ensures that the beer diverted into the intermediate container 11 does not come into contact with the pressure medium. This ensures a particularly high level of cleanliness of the beer, which could possibly be slightly contaminated by the pressure medium, provided that the pressure medium can somehow mix with or dissolve in the beer, which, for example, when using air as Print medium is conceivable.
  • the separating film 33 also enables the use of not only gaseous pressure media, but also liquid pressure media, for example water, because it always tightly separates the container part 35 from the container part 34 containing the beer.
  • the separating film 33 also provides the advantage that it prevents beer from entering the connector 17. Such penetration is possible in the event that beer or foam rises into the connecting piece 17 due to incorrect operation.
  • shut-off valves shown in the figures can be manually operated or automatically controlled valves.
  • solenoid valves are expediently used, which are activated in a known manner by a sequence control.
  • a relay circuit or programmed electronic circuit can be used in a known manner as sequence control.
