Definitions

  • the present invention relates to a device for enriching water with CO 2 gas for the production of carbonated water in a storage container, which is acted upon by cooling lines of a cooling circuit for cooling its contents and for forming an ice jacket in the wall area, in the interior of which a circulation pump is arranged, through which CO 2 gas from the head region of the storage container is mixed into the water and / or the water inside the storage container is rotated and / or circulated, and into which both water and CO 2 gas can be supplied in the head region and can be removed from the carbonated water in the bottom area.
  • Such devices for enriching water with CO 2 gas for producing carbonated water are used, for example, in devices by means of which CO 2 -containing soft drinks can be prepared and dispensed by mixing carbonated water with an appropriate beverage concentrate.
  • the soda water to be mixed in the beverage concentrate is created in the storage container by enriching water with supplied CO 2 gas and cooled for better carbonation and as a prerequisite for a prepared cool soft drink.
  • Normal water of drinking quality is fed to this storage tank, the so-called carbonator, either from the line of a water supply system or from a storage tank under sufficient pressure, whereby the water supplied can itself be under pressure or can be pumped into the carbonator exclusively or additionally by a pressure pump.
  • the carbonizer is supplied with CO 2 gas, specifically from a CO 2 gas storage container via a pressure reducing valve, so that a pressure of, for example, approximately 4 bar is built up in the carbonator.
  • the carbonization of the water in the carbonator is carried out or supported by the supplied CO 2 gas by means of various measures, the use of circulation pumps arranged in the carbonator having proven successful. These suck this CO 2 gas out of the head region of the carbonator, which is filled with CO 2 gas, and introduce it into the water which is set in motion, in particular in rotation.
  • cooling the carbonator serves on the one hand to improve the carbonation and on the other hand as a prerequisite that the final prepared and dispensed beverage has the desired low and essentially constant temperature.
  • the carbonator is expediently cooled by means of a cooling system which is able to build up an ice jacket in the side region of the side walls of the carbonator, which ice jacket is formed to a certain extent by the circulated water.
  • a cooling system which is able to build up an ice jacket in the side region of the side walls of the carbonator, which ice jacket is formed to a certain extent by the circulated water.
  • the output a freshly prepared soft drink in a way that connects to the bottom area of the carbonator Line a shut-off valve is opened and the cooled, carbonated water taken for this purpose.
  • a shut-off valve is opened and the cooled, carbonated water taken for this purpose.
  • the water from in view of the ice coat being formed in the area of the cooling coils near the freezing point is cooled, there is a certain risk that ice particles or parts get into the area of the outflow opening and clog them.
  • Ice formation within the storage container is said to be in areas done for the other operation of the storage container are unproblematic as a carbonizer.
  • This Areas are the side walls of the storage container, which of the cooling coils of the cooling system is thermally good are surrounded by conductors. This area is actually going to develop ice formation and an existing one Ice cooling will also increase there with further cooling. Problems in the operation of such carbonizing Reservoirs have led to observations which showed that at least with carbonated water this with the usual, constant heat removal can cool below the typical freezing temperature without that ice formation begins.
  • a device for enriching water with CO 2 gas for the production of carbonated water in a cooled storage container which does this task, is according to the invention characterized in that in the storage container in the region of its wall provided with the cooling lines of the cooling circuit different from the cooling lines constructive Measures for targeted local ice formation, which is preferable to the other areas, have been taken.
  • a space for the storage container content is separated, which is open to the interior of the storage container with little or no flow.
  • This separated space is preferably less than 100 mm 3 and it is advisable to design it in less than 10 mm 3 .
  • This preferred embodiment in the form of one from the interior of the storage container fluidically separated space is for example through on the reservoir wall in the area pipe attached to the cooling line can be realized.
  • a extremely practical implementation is also given such that the fluidically calmed room is formed by one directed outwards between two cooling line coils Characterization of the wall of the storage container and one of these Characteristic as far as possible compared to the interior of the storage container covering circuit board.
  • Another preferred measure for partial, advanced ice formation realize that the wall of the reservoir at least partially acted upon by the cooling line roughened upper area opposite the inside of the storage container and otherwise in the lower area of the storage container is smooth.
  • the measures according to the invention result in partial in a limited range of crystallization points for ice formation be created from which the formation of the desired Ice jacket with appropriately cool water trains as desired.
  • Partial hypothermia of the wall are otherwise difficult to implement because of the heat conduction in the wall and through heat conduction and in particular the convection in the liquid such differences can hardly be made relevant unless with considerable effort.
  • the separation of a small amount of liquid of the total fluid causes in this relatively small and fluidically isolated Space a targeted early ice formation, which is characterized by small, open spaces from this separate room in the Reproduced storage container.
  • a storage container 1, as shown in FIG. 1, is suitable and intended for use in devices for the preparation of soft drinks by admixing an appropriate concentrate to carbonated water or possibly also to normal water.
  • Fresh water is supplied to the storage container 1 via a feed line 2, and CO 2 gas is fed via a feed line 3.
  • Sufficiently carbonated and cooled water is removed in portions in the storage container 1 via an outlet line (not shown) in order to prepare a soft drink.
  • the sufficient carbonation is at least supported by a circulation pump 5 driven by an electric motor 4, which sucks the CO 2 gas located there from the head region 6 of the storage container 1 via an intake pipe 7 and mixes it into the stored water at the level of the circulation pump 5. This CO 2 gas is largely dissolved in the water 8.
  • the water supply is cooled via evaporator coils 9 of a cooling system, not shown, in such a way that inside the reservoir 1 in the area of Evaporator coils 9, which have good thermal conductivity on the wall of the storage container, an ice jacket 10 builds up.
  • the thickness of this ice sheet 10 is determined by a Ice sensor 11 monitors from which the refrigeration cycle and so that the cooling capacity is controlled.
  • the ice jacket 10 causes a very constant water temperature near the Freezing point and provides cold potential when cold Water from the reservoir and refill against warmer water in the storage container.
  • Evaporator line 9 a room to the inside of the storage container although open, but fluidically in there water located soothing arranged.
  • FIG. 2a shows this room somewhat enlarged as the interior a small tube 13, which is perpendicular to the wall of the storage container 1 with respect to a turn of the evaporator line 9 is attached. It turns out that this Room 12 when the water cools down to and below freezing preferentially forms ice and in this case supercooled water from this crystallization point the ice jacket on the wall relatively quickly and suddenly, which is surrounded by the remaining evaporator line 9. The other areas within the storage container 1 remain ice-free. Above this crystallization point through space 12 is due to the density behavior water is more likely to experience hypothermia, so that the formation of ice develops rapidly upwards.
  • Figure 2b shows an even more vis-à-vis the interior of the reservoir 1 closed space 12 ', the only over the surrounding cage with the reservoir inside communicates via two small bores 15. This will secure this space filled with water and the ice crystals can be essentially unhindered develop to the outside.
  • FIG. 2c shows a modification of the training a separate one, which is used for the formation of ice Room 12 '' than this room through an indentation in the Wall of the storage container 1 between two turns of the Evaporator line is realized by a cover plate 17 is covered with two small openings 18.
  • Figure 2d also shows a possible measure for implementation one against the inside of the storage container open, but fluidically calmed room 12 '' ' with a corresponding to the wall of the storage container 1 attached cap 19, opposite a turn of the Evaporator line 9. In any case, it must be ensured that that in the closed space 12 liquid of the reservoir can penetrate and there until ice formation remains.
