Definitions

  • the present invention relates to a device and the use of a device for enriching water with CO2 gas for the production of carbonated water in a storage container, which is provided for cooling its contents and for forming an ice jacket in the wall area with cooling lines of a cooling circuit in the inside of which a circulation pump is arranged, through which CO2 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 in which both water and CO2 gas in the head region can be supplied and removed from the carbonated water in the bottom area.
  • Such devices for enriching water with CO2 gas for the production of carbonated water are used, for example, in devices through which CO2-containing soft drinks can be prepared and mixed by mixing carbonated water with an appropriate beverage concentrate.
  • the beverage concentrate Soda water to be mixed is created in the storage container by enriching water with CO2 gas supplied and cooled for better carbonation and as a prerequisite for a prepared cool soft drink.
  • Normal water of drinking quality is fed to this reservoir, the so-called carbonator, either from the line of a water supply system or from a reservoir 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 carbonator is supplied with CO2 gas, namely from a CO2 gas reservoir via a pressure reducing valve, so that a pressure of, for example, approximately 4 bar is built up in the carbonator.
  • CO2 gas namely from a CO2 gas reservoir via a pressure reducing valve
  • the carbonation of the water in the carbonator with the supplied CO2 gas is carried out or supported by various measures, the use of circulation pumps arranged in the carbonator having proven successful. These suck this CO2 gas from the head area of the carbonator filled with CO2 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 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 is formed to a certain extent by the circulated water.
  • a shut-off valve is opened in a line adjoining the bottom area of the carbonator and the cooled, carbonated water is removed for this purpose. Since the water is cooled in the vicinity of the freezing point in the area of the cooling coils with regard to the ice jacket which is being formed, there is a certain risk that ice particles or parts will get into the area of the outflow opening and block it. Ice formation in this area itself is rather impossible, because due to the special behavior of the water with regard to its specific density in the vicinity of the freezing point, the somewhat warmer water would sink downwards, and since the outlet opening is expediently arranged in the vicinity of the circulation pump, which radiates some heat is.
  • a device which meets these requirements is characterized in that a time control circuit is provided and the circulation pump within the Storage container, which is used to produce carbonated water by enriching water with CO2 gas, controlled by the time control circuit, is put into operation and taken out of operation in continuous cycles.
  • a device with measures according to these features of the invention is characterized in that the sufficient carbonation of the water with CO2 gas is accomplished and / or supported in the operating phases of the circulation pump and the ice jacket is formed essentially in a ring shape on the cooled wall of the storage container.
  • the carbonized water can layer up according to its natural density, whereby the slightly warmer water sinks down and the somewhat colder water rises together with any ice particles or ice particles that may be present, whereby the ice particles and ice particles tend to come together and lie on the ice jacket in the upper area of the carbonator.
  • the circulation pump can be clocked by a timing control circuit that functions simply in terms of control technology.
  • the device according to the invention is preferably operated in such a way that the on-time of the circulating pump is approximately 1 to 2 minutes and the ratio of the on-time to the off-time is approximately 1:10 to 1:20. It turns out that a switch-on time of one to two minutes within switch-on-switch-off cycles from 1:10 to 1:20 is sufficient re-carbonation of the water and is able to achieve a sufficiently uniform ice jacket design.
  • the use of the device according to the invention is characterized in that when carbonated water is removed from the storage container or when fresh water is supplied to the storage container, the circulation pump is put into operation during this phase including a follow-up phase. A follow-up phase of approx. 2 to 4 minutes is advisable. Then the control cycle starts again, in which the circulation pump is switched on for 1 to 2 minutes and the switch-off time between the switch-on phases is 10 to 20 times as long.
  • a storage container 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 reservoir via a supply line 2 and CO2 gas is supplied via a supply line 3.
  • Sufficiently carbonated and chilled water is removed in portions via an outlet line 4 in order to prepare a soft drink.
  • the sufficient carbonation is at least supported by a circulation pump 5, which sucks the CO2 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 8 at the level of the circulation pump 5. This CO2 gas is largely dissolved in the water 8.
  • the circulation pump 5 is driven by an electric motor 9.
  • the cooling of the water supply takes place via evaporator coils 10 of a cooling system, not shown, in such a way that an ice jacket 11 builds up in the interior of the storage container 1 in the region of the evaporator coils 10, which rest on the wall of the storage container 1 with good thermal conductivity.
  • the thickness of this ice jacket 11 is monitored by an ice sensor 12, from which the refrigeration cycle and thus the cooling capacity is controlled.
  • this ice jacket 11 has the effect that, without very sensitive detection and evaluation measures, the supply of water 8 is cooled to a very constant temperature in the immediate vicinity of the freezing point, and the temperature is also essentially maintained when water changes take place, ie when carbonized Water is removed via the outlet line 4 and - controlled by a water level sensor 13 - warmer water is supplied via the feed line 2 for this purpose.
  • the ice jacket degrades relatively quickly around sub-areas, which then be built up again by cooling power supplied via the evaporator lines 10.
  • a known measure is to prevent icing of the outlet opening by arranging it in the vicinity and / or below the circulating pump, the heating, in particular of the drive motor 9, having a positive effect against icing.
  • this measure cannot be sufficient against floating ice particles.
  • the electric motor 9 is driven intermittently.
  • An operating phase of approx. 1 to 2 minutes is followed by a rest phase of approx. 10 to 20 times the length.
  • the circulated water 8 calms down and ice particles and ice particles floating in this water, because of their lower density, endeavor to reach the area of the surface of the water in order to unite there and / or in the edge areas to put on the ice jacket 10.
  • these hazard elements are thus neutralized.
  • the electric motor 9 is actuated each time carbonized water is added or fresh water is added, and the circulation pump 5 is put into operation for these time periods including a follow-up time, after which the switch-on-switch-off cycle starts again as originally.
  • the circuitry measures are arbitrarily simple and can be implemented, for example, in that a signal is derived from the water level sensor 13, which sets a counting chain into an initial situation during a water inflow, which causes the power supply switch 15 to the electric motor 9 to be closed. If the water level sensor 13 detects that enough water has been refilled, the water supply via the feed line 2 is blocked and the counting chain 14 begins to run off. For a time range of 1 to 2 minutes, depending on the design of the counting chain, the switch 15 remains closed, after which it is opened until the counting chain has reached the upper setting value, after which it can be switched back to the initial situation and run through again.
  • FIG. 2 shows a modification of a storage container according to FIG. 1, wherein the storage container 1 'only has evaporator coils 10' applied to it in the upper wall area is so that the ice sheet is also preferably formed in the upper region of the storage container 1 '.
  • the circulation pump 5 'and its drive motor 9' run coils 16 through which other water to be cooled is passed through the carbonized water. Due to the resting phases of the circulation pump, the somewhat warmer water 8 'collects in the lower zones of the storage container 1' because of its greater density, so that a risk of icing in the coils 16 is also prevented.
