Until now, only ice or ice water has been used to cool liquids, namely beer used, which, acting indirectly, by radiation that contained in a vessel, to cooling liquid cools down to a certain required temperature or, if it is, how z. B. can occur in winter in cold cellars or very cold weather, it is To temper the beer, instead of the ice, a heated liquid is used as a means for Temperature change is used, which works in the same way as the ice in the case of cooling. Cooling The medium and the liquid to be cooled do not come into contact with each other, becoming one routed through a pipe usually formed as a serpentine, the other is located in a vessel surrounding this line.

The new method differs from the previously customary cooling method in that the bezw come to use beer. the liquid by mixing with an equal, previously cooled or tempered liquid is brought to the desired temperature.

For example, to cool or warm the beer to be tapped from a keg, one mixes the beer in the keg to the degree that the draft goes on, with beer from another barrel, but that during its transition into the first barrel Tempering resp. Cooling process with the aid of any suitable (cooling) device previously subjected and on. such a temperature has been brought that through the mixing of the two liquids with each other now the beer in the second barrel desired temperature, but the beer coming from the first barrel at the same time it is also used to automatically drive the beer to be tapped out of the "mixing vat".

The accompanying drawing shows the arrangement of the device, for example for Cooling resp. The tempering and tapping of beer is set up.

A barrel A is connected by a tap B of known design through a pipe C to the pressure device (air pump, carbon dioxide bottle, etc.) on the one hand, and to a cooling device E on the other hand through a pipe D , so that the beer expelled from A in a known manner through D. after E enters the cooling coil F. Coming from F , however, it is not directed to a tap, but goes down through a pipe G into the cellar to a second Fafs H, standing next to the first, which is provided with a tap J identical to the first. But now the beer pipe G is connected to the air pressure connection K of this tap; so that the high- pressure beer from A , cooled (tempered) in EF now enters the barrel H and mixes with the beer in it.

The mixture will naturally take place and thereby effect the cooling of the contents of H , because the cold beer arriving from G sinks to the bottom in the barrel H , but as an overpressure is created in this barrel as a result of the forcible passage of beer from A to H , at the same time the beer rises from the cool bottom of the keg H through pipe L and in this way reaches a second cooler M, from

Claims (1)

your finally a pipe N leads to a tap. It can be seen from the process and the device described that only the tank A is emptied, but that H is always filled again from A in accordance with the removal from it; Likewise one recognizes that the contents of A can be carried over to H up to the last remainder , so that there is no loss in A , that no "stale" remainder can form at all which can be served. If, however, the Fafs A is empty, H must take its place and a new Fafs is set up for A , which, however, now has the position that H previously occupied, while the Fafs H now takes over the function of A. Accordingly, a change in the pipeline must also be made, as indicated by the dotted lines. Instead of the pipe C, which is connected to the air connection of the cock B , the compressed air line C ^{1 is} now connected to the connection K of the cock /. The tube G is removed and replaced by a pipe G '. ² The beer is now pressed from H through LMG ' ² , with it being cooled in M , into the keg that has been placed in place of A. From this keg the beer goes through D and the snake F and reaches the also newly introduced nozzle N ¹ . Now the barrel H is emptied down to the last remainder and so work continues with a constant change of inlet and outlet connections and the replacement of an empty barrel with a full one. From this mode of operation, however, it can also be seen that once operation has been initiated, the Cooling is actually fourfold. The pre-chilled beer from the previous period In the now emptying faf, the first cooler continues to cool, then it enters the new one "Durchgangsfafs" cools its content and at the same time displaces it, so that it leads to the second Cooler arrives, where again a temperature reduction of the mixed product takes place before the beer comes to the bar. Loss of beer residues is completely excluded because the remains are always full Fafs are driven and therefore cannot become stale, because they are never free Are exposed to air, but all processes are always in front of you with complete air exclusion walk. In short, the procedure consists of the following: Means a suitable one Pressure device is liquid from an airtight vessel through a cooling device driven into a second full vessel with an equal liquid, mixed 'here with the non-cooled liquid, and drives it out of the second vessel a second cooling device to get from this to the place of use. If then the first vessel is emptied, a new, full vessel is put in its place and the two, Vessels that are now full stand in the same relation to one another as the first and second, this one but now takes the place of the first in order to get the liquid out of the new (third) vessel to drive out until it (the second) is empty, whereupon a new, full one in its place Which now takes the place of the second, while this takes the place of the third is set. The pipeline is adjusted accordingly with every change of faf, so that there is always circulation of the liquid from the newest vessel through a cooling device after the second newest, where both liquids are mixed, and then from this the drain through a second cooling device to the point of use takes place and so on in constant alternation. The cooling vessels can be of any type, only they have to meet the condition that they can be brought into alternating connection with one another, so that they are in their activities can be exchanged with one another in sequence. If a liquid is to be tempered or moderately warmed instead of being cooled, in use some kind of warming liquid instead of ice or ice water. As an example of a suitable device, the one shown in the drawing is built. In a shared ice container E , two separate tubular columns F and M are set up next to each other, each with a feed nozzle O respectively. O ¹ and a Auslafsstutzen P and P ^1, which are arranged so, that a change, once O as the first and O can serve as the second supply pipe ', while the Auslafsstutzen P first BEZW to the median line of the liquid after the second feed connector O. ¹ to the second cooling column and the second drainage pipe can serve to discharge the liquid to the place of use, and vice versa. Patknt claims: i. A method for cooling BEZW. Heating liquids, characterized in that that from an airtight vessel liquid by means of a pressure medium through a cooling resp. Warming device driven and from there into a second, also hermetically sealed vessel, so that it is carried along with it mixes the liquid of the same type contained therein, whereby by the in the mixing vessel generated overpressure the mixture after a second cooling resp. Heating device is driven and passes through this to the point of use.
For carrying out the method according to claim ι a device, characterized in that, after the first vessel has been emptied, a third full vessel is placed in its place, which now takes the place of the mixing vessel, while the primary pressure medium after previous change of the corresponding lines now acts on the liquid in the second vessel and drives its contents in the same way through the second cooler to the current mixing vessel, so that its contents are driven through the first cooler to the point of use. 3. To carry out the method characterized in claim 1, the arrangement of two cooling columns (F and M) in a cooling container (E), which can be interrelated in such a way that the first through a drain pipe (G) indirectly through the container ( H) with the inlet pipe (L) of the second. can be tied, whose drain pipe (N) then leads to the point of use, but that the second can also be brought into connection indirectly through the container (A) with the inlet pipe (D) of the first through a newly inserted drain pipe (G ² J) which a newly installed waste pipe (N ¹ ) leads to the point of use. 1 sheet of drawings.
