Chilled beer line pipe

In the case of beer dispensing systems, it is particularly important to be considerate
Due to the spatial conditions or the operational sequence, it is often necessary to store the beer keg or kegs in question in a special cooling compartment or cooling room that is at a distance from the counter, for example
in the cellar below the bar,
is housed. In order to supply the beer in the keg or kegs to the dispensing column, a special beer pipe is necessary, which is generally surrounded by a jacket made of a heat-insulating material. However, a considerable amount of beer still remains within the beer pipe, which heats up over time. If beer is not continuously poured out, the beer that is still in the beer pipe and warmed up in the meantime is served. This amount of beer, which has been heated in the meantime, is greater, the longer the beer pipe connecting the beer keg to the dispensing column is

The object of the present invention is now to eliminate this still existing problem what according to the invention is achieved in that the beer line pipe at least one serving to promote the beer itself Has a beer hose or a so-called beer cylinder, which in turn is supported by a constantly flowed through by a cooling medium Cooling tube is surrounded, which not only prevents the entry of heat from the outside, but also a constant cooling which still causes the amount of beer remaining in the beer hose.

A particularly useful embodiment of this beer line pipe is characterized in that the cooling tube is designed as a twin tube that comes from one of the receptacles and cooling of the beer hose or the like serving inner tube and an outer cooling tube surrounding the latter consists.

Advantage if the inner tube on the one hand to the evaporator of this cooling compartment and on the other hand to the interior of the dispensing column connected. If this is the twin pipe that has already been treated, then in this case it is the inner pipe connected to the evaporator of the refrigerated compartment and opens into the interior of the dispensing column, which is closed to the outside, the outer cooling pipe, the latter of which is the dispensing column, is then connected again to this interior space of the dispensing column

remote end opens into the interior of the cooling compartment. This type of design and connection of the twin pipe is particularly advantageous in that the cooling air branched off from the evaporator first flows past the beer hose or the like installed in the cooling pipe and used to convey the beer, and enters the interior of the dispensing column , cools the same and then returns to the interior of the ζ) cooling compartment in countercurrent via the outer cooling tube.

Since the cooling capacity of the evaporator is essentially based on the cooling compartment itself, the Beer pipe only a subset of that from the evaporator exiting cooling air required. For this reason, the ventilation inlet cross section of the cooling pipe extends, in particular thus also of the inner tube, but only over part of the air outlet cross-section of the evaporator.

Furthermore, in order to ensure a good conveyance of the cooling air, it is also advantageous if between the air inlet nozzle and one connected to the cooling pipe Lufteinblasrohr a the cooled air sucking in and conveying to the dispensing column fan od. The like. Is arranged.

Further features of the invention and their technical advantages emerge from the following description of a exemplary embodiment in conjunction with the claims and the drawing.

To promote the beer located in the beer keg 2, a beer hose or beer cylinder designated 14 is used provided, which is connected on the one hand to the beer keg 2 and on the other hand to the tap belonging to the dispensing column 4 connected is.

The aforementioned Lufteinblasrohr 19 has at its free Ii end of a designated 21 air inlet nozzle, the extends only over part of the evaporator cross-section and thus only absorbs part of the cooling air conveyed by the fan 7 belonging to the evaporator.
