Definitions

  • the invention relates to a filling element of the type mentioned in the preamble of claim 1.
  • Filling elements of this type are used in beverage fillers for high-quality beverages, in particular beer, which have to be protected to a particular degree against exposure to air.
  • the drink In the kettle of the filling device, the drink is under a predominantly CO2 atmosphere and is therefore largely protected against air access. If an empty container is filled with air, the drink comes into contact with pure air. In the usual construction of filling devices, the container air flows back into the boiler as return air and there also results in disturbing air influence on the beverage.
  • a filling device of the type mentioned is known from FR-A-2 078 036.
  • a vacuum line is provided, the vacuum of which is limited at the bottom by a corresponding control device, so that when unstable containers are evacuated, their collapse is prevented.
  • the gas valve is opened, from which compressed gas flows into the container without throttling.
  • the result is that the pressure in the container immediately rises to the high pressure level of the compressed gas supplied. Gas is then still flushed through the container into the vacuum line.
  • this takes place at a high pressure level of typically a few bars, the purging action being limited with regard to the remaining, less disturbing residual gas fractions.
  • there is a high consumption of compressed gas there is a high consumption of compressed gas.
  • the object of the present invention is therefore to provide a filling element of the type mentioned at the outset which, with low compressed gas consumption, enables a better purging action with regard to disturbing residual gas fractions.
  • the construction according to the invention provides a throttle in the gas channel, that is to say in the compressed gas supply, which is dimensioned in relation to the vacuum-side suction power in such a way that only very small amounts of gas flow in which the vacuum pressure does not increase or does not increase appreciably. It takes place So flushing with compressed gas at a low vacuum pressure level instead. However, this only gives the essential advantage that small portions of residual gas, in particular portions of disruptive oxygen, are effectively flushed out. The resulting low throughput of compressed gas also leads to savings in compressed gas (CO2). Since the maintenance of the low vacuum pressure level is guaranteed, vacuum pumps can be used which break down if the pressure increases too high.
  • flushing can also be used in this way in those filler organ constructions which work with liquid valves which open automatically under spring pressure and which, of course, must not yet open during evacuation and flushing.
  • the throttle can be switched off so that the gas channel can lead gas into the container with high throughput, ie with great speed, during the prestressing process.
  • the invention is shown for example and schematically in section through a filling element according to the invention with a gas duct designed as a return air pipe.
  • a filling element 2 is connected to the ring bowl 1 of a rotating filling device and extends radially outward.
  • a liquid connection 3 connects the liquid space of the ring bowl with the area above the liquid valve 6 of the filling element and a gas connection 4 connects the gas space of the bowl with the gas space 5 of the filling element.
  • a return air pipe 9 connecting the inside of the bottle to the gas space 5, which is arranged to be vertically movable in the filling element 2 and carries the liquid valve 6.
  • the liquid valve is designed to be self-opening. It is supported by a compression spring 11 against the filling element via a flange 10 on the return air pipe 9 and thus opens automatically when equal pressure is established between the interior of the bottle 8 and the gas space 5.
  • the return air pipe 9 projects with its lower end 12 into the bottle 8 up to the height to which it is to be filled, as is the case with conventional ones Return air pipe constructions for known purposes of controlling the filling stop is common.
  • an expanded pipe section 13 is provided, in which a valve body 14 of the gas valve is provided.
  • the valve body 14 has at its upper end two vertically spaced, transverse actuating plates 15 and 16, between which an actuating lever 17 can be brought into engagement, which can be actuated from the outside via a shaft 18 which passes through the housing of the filling element 2.
  • an actuating lever 17 By pressing the operating lever 17 from above onto the lower operating plate 15, the valve body 14 can be moved downwards and can be moved upwards by pressing from below against the upper operating plate 16.
  • the lower actuating plate 15 is further supported in the usual manner downwards against a flange 20 of the return air pipe via a compression spring 19.
  • annular seal 21 is provided, with which the valve body 14 can come into sealing engagement on the bottom 22 of the expanded pipe section 13, as a result of which the return air pipe 9 is closed.
  • the actuating lever 17 initially remains force-free. Both the return air pipe 9 and the valve body 14 are in the lower closed position and are held there against the pressure of the compression springs 11 and 19 by the gas pressure in the interior of the filling element.
  • the bottle 8 is now brought under the outlet 7 of the filling element and held in the sealing position. Then, by lifting the operating lever 17, the valve body 14 raised, and gas flows into the bottle 8 until it has the same pressure (constant pressure) as in the gas space 5. Then, under the action of the compression spring 11, the liquid valve 6 automatically rises and liquid flows into the bottle 8 until it reaches the lower end 12 of the return air pipe 9.
  • the filling element shown is used for filling high-quality drinks, in particular for filling beer. Care must therefore be taken to ensure that the air influence on the beverage is as low as possible, which is why pre-evacuation is used in a known manner.
  • a vacuum ring line 30 is provided under the ring bowl 1, which is connected in the area of the filling element shown with a connecting pipe 31 to an annular channel 32 arranged in the housing of the filling element around the outlet 7.
  • the vacuum can be connected to the outlet 7, that is to say to the inside of the bottle 8, by actuating a vacuum valve shown in the figure.
  • This has a valve stem 33 which carries a valve plate 34.
  • a button 36 At the outwardly projecting end of the valve stem 33 there is a button 36 which can be actuated from the outside against a spring 35.
  • the Valve plate 34 closes a bore 37 which connects the ring channel 32 to the outlet 7.
  • the vacuum valve shown opens and connects the inside of the bottle 8 to the vacuum ring line 30, which is connected in a suitable manner to a vacuum pump, for example a commercially available water ring pump.
  • pre-evacuation devices on filling elements are known.
  • the container 8 is pre-evacuated by opening the vacuum valve shown, while the liquid valve 6 and the gas valve 21 are closed.
  • the weak suction power of the vacuum pumps usually provided and the long, lossy vacuum lines only a weak vacuum is achieved in the container. So there is still air in the container.
  • the invention provides that the control devices, not shown, which actuate the vacuum valve and the gas valve shown, are designed in such a way that the work cycle described below results:
  • the vacuum valve 36, 34 is first opened and the bottle 8 is evacuated.
  • the gas valve 14, 21 is then opened. Now gas flows from the CO2 atmosphere into gas space 5 in the container. This gas is also drawn off when the vacuum valve is open. This results in a flushing of the interior of the bottle 8 with largely air-free gas from the gas space 5, so that the final resulting air partial pressure in the bottle 8 is significantly lower than if only evacuation.
  • the invention provides for a throttle to be provided in the gas duct, which throttles the gas flow rate.
  • a throttle piece 24 is arranged below the valve body 14 for this purpose, which is arranged concentrically in the return air pipe 9 with a narrow gap 25.
  • the control device controlling the actuating lever 17 is designed such that it raises the valve body 14 slightly during the pre-evacuation, that is to say when the vacuum valve is open, so that the throttle piece 24 remains in the return air pipe 9 over its essential length, the gap 25 having a strongly throttling effect.
  • gas flows into the bottle with a greatly reduced feed rate.
  • the gas valve can be closed again in good time without high precision requirements for the time control, before a constant pressure is established in the bottle and the water valve opens.
  • the throttling action that is to say the dimensioning of the gap 25, is advantageously provided such that the gas inflow power is lower than the vacuum power. So less gas flows in than can be sucked off, and an excessive increase in the gas pressure in the bottle 8 is avoided.
  • the gas valve can also remain open until after the vacuum valve has been closed, so that the bottle 8 is then pretensioned immediately after the end of the evacuation.
  • valve body 14 Since, in this stroke position of the valve body 14, the throttle would also work during the pretensioning, as a result of which the pretensioning time is lengthened unfavorably, the valve body 14 is preferably raised over a substantially larger stroke during the pretensioning, to the position shown in dashed lines. The throttle piece 24 is completely lifted out of the return air pipe, so that it is available with a full cross section for rapid pretensioning.
  • the filling element can be largely varied compared to the illustrated embodiment.
  • the vertical movement of the return air pipe 9 and the liquid valve can be provided separately.
  • a fixed gas channel can also be provided, which can also not be arranged in the center of the filling element, but can, for example, be arranged outside in the wall thereof.
  • the filling element according to the invention can also be varied in a known manner for filling cans.
  • the gas used for purging during the pre-evacuation does not have to come from the gas space 5 of the boiler, as in the illustrated embodiment, but can be supplied for a particularly high requirement from a separate fresh CO2 source, in the feed line in the manner according to the invention a gas valve, if necessary with a throttle.
  • a different throttle construction can be provided, for example in the form of a permanently acting, fixed throttle or, in the case of the preferably provided switchable throttle, in the form of several parallel switchable channels with different throttling effects.
