Definitions

  • the invention relates to a device for dispensing beer, with a tap which is connected via a tap to a beer supply which has a plurality of separate containers, which are connected to a pressurized gas source and, via associated output lines and a switching device connected to a control device, in succession the tap line can be connected.
  • the output lines of the individual beer containers are connected via the switching device to an intermediate container which is equipped with probes which indicate to the control device that the container is emptying.
  • Switching valves designed as solenoid valves are then actuated by means of the control device, which interrupt the outlet line of the emptied container or release the outlet line of the next full container.
  • the disadvantage of this design is that the intermediate container must be cleaned periodically for hygienic reasons, which is associated with a considerable amount of work and a longer downtime.
  • solenoid valves there is also the disadvantage that the solenoid valves heat up in the ready state, so that the beer, if not tapped for a long time, to a line length of e.g. 0.5 m can reach a temperature up to 40 ° C. However, the carbonation of the beer is released and the quality is reduced.
  • the invention aims to design a device of the type specified in the introduction in such a way that an essentially continuous dispensing operation is ensured with a high standard of hygiene.
  • the device according to the invention is characterized in that the switching device has ball valves with pneumatic actuation which are switched into the outlet lines of the individual containers and which have the same passage cross section as the outlet lines, the outlet each ball valve is directly connected to the tap line, which also has the same cross-section as the outlet lines, and that each ball valve is assigned a vent valve and each outlet line is connected to the associated container with a sensing device arranged outside the line, which, in the absence of liquid flow in the outlet line, sends a changeover signal transfers to the control device.
  • the main advantage of the invention is that the beer flow between the storage container and the tap is not interrupted by any intermediate containers and the flow cross-section from the container to the tap is constant, i.e. has no constrictions or extensions, so that the outlet lines and the dispensing line can be cleaned periodically in a simple manner with balls and sponge, which are pressed through the lines by means of carbon dioxide. This ensures operation with only minor interruptions, high hygiene standards and consistent beer quality.
  • a dispensing device for beer is known from DD-PS 21 135, in which the outlet lines of several kegs are connected to a common tap via two-way valves, the outlet line and the outlet lines having the same cross-section.
  • the two-way valves must be moved from the bar table by means of a cable.
  • a beverage delivery device in which several drums are connected with their output lines to a cylinder with a motor-operated rotary piston, via which the output lines can be connected to a dispensing line after actuation of a selector switch.
  • the same flow cross-sections are also present in the outlet lines and in the tap line, but the device is not as easy to clean as the one according to the invention and, moreover, is constructive much more complex.
  • a method for the gas-free emptying of several tanks e.g. for beer, known in which two electrodes are provided to prevent gas from entering the liquid during the automatic switchover.
  • One electrode sits e.g. in the tank bottom and switches a throttle valve located next to the main valve in the drain line, whereas an end electrode in a sump vessel closes the main valve.
  • a degassing valve is switched on in the drain line.
  • the known embodiment has the disadvantage that perfect cleaning, as in the case of the invention, is not possible because of the sump vessel and the throttle valve. In none of the known devices discussed above, a continuous tap operation with simultaneous flawless cleaning is guaranteed.
  • the device shown is intended for dispensing beer from three storage containers 1, 2, 3, but the invention can be applied to any number of containers.
  • the containers 1, 2, 3 are connected via associated outlet lines 1 ', 2', 3 'to associated shut-off devices which are designed as ball valves 4, 5, 6.
  • a pneumatic switching or actuation valve 7, 8, 9 is assigned to each ball valve, these valves being connected via a line 17 to a compressed air source and via signal lines (not shown) to a central electronic control device 10.
  • gas valves 14, 15, 16 are switched on, which are connected via a central gas line 17 'to a compressed gas source, not shown.
  • the Gas valves 14, 15, 16 are also connected to the central control device 10 via electrical signal lines, not shown.
  • the ball valves and valves are housed together with the control device in a housing G.
  • the ball valves 4, 5, 6 and the tap lines 1 ", 2", 3 "emerging from them have the same passage cross section as the outlet lines 1 ', 2', 3 '.
  • the tap lines open into a central line section 18, which also has the same cross section and if necessary leads via a pump, not shown, to a tap Z.
  • the outlet lines 1 ', 2', 3 ' are assigned to the associated containers, sensing devices 19, 20, 21 for the presence of the liquid flow, which are arranged outside the respective line and are connected to the control device 10 via electrical signal lines 22, 23, 24.
  • Each ball valve 4, 5, 6 is further equipped with a manually operable vent valve 4 ', 5', 6 'for the associated output line.
  • the device shown works as follows: after switching on the preprogrammed control device 10, a switch-on signal is emitted from it to the switching valve 7 of the pneumatic drive of the first ball valve 4 and the latter is opened thereby. At the same time as the ball valve 4, the associated first gas valve 14 is opened via the control device 10, so that the propellant gas enters the container 1 and drives the beer via the outlet line 1 'and the ball valve 4 and the dispensing line 18 to the tap.
  • a warning display which optically or acoustically indicates that only one container is left in stock or the last container has been tapped.
  • the already emptied containers are then exchanged for full ones and the outlet lines 1 ', 2' etc. are vented via the vent valve provided on the associated ball valve, so that they can fill with liquid under the effect of the internal pressure of the container before the control device empties of the last container switches back to the first container and the beer dispensing begins again in the manner already explained by opening the first ball valve and the associated propellant gas valve.
  • each outlet line 1 ', 2' etc. and the closing speed of the ball valve are selected so that when the container is emptied the outlet line can only be filled with propellant gas over part of its length.
  • Periodic cleaning of the lines acted upon by the beer is carried out in the usual way by means of balls and sponge, which are pressed through the lines by means of carbon dioxide.
  • the manually operated vent valves 4 ', 5', 6 ' can also be designed as automatically actuated valves.
  • the switching valves for the ball valves can also be operated using the propellant gas for the beer.
