  • the storage container is used, which is cooled by a cooling system in the automatic vending machine for the preparation of CO-containing soft drinks, to the extent that in the area of the wall areas surrounding the cooling lines of this cooling system, an ice jacket penetrates into the Builds up interior of the reservoir.

It is also possible for the liquid line, which is coupled to the storage container from the outside with good thermal coupling, to be arranged in a thermally contacting manner in the lower region of the storage container with its walls. Both measures can also be implemented with one another, the arrangement of this liquid line in the lower region of the storage container taking advantage of the fact that no ice layer is built up there. There is therefore no need to fear icing within the beverage line that is led through or past.

As soon as one of these three valve systems 4 is replaced by a set control circuit is actuated, this actuated valve system 4 conveys a corresponding concentrate from the assigned storage container 3 into the mixing trough 2. At the same time or overlapping a shut-off valve 5 is opened so that carbonated water from a storage container 6, which is treated and cooled there , are passed through a flow regulator 7 into the mixing trough 2 under pressure. In this mixing trough 2 the beverage concentrate dispensed and the carbonated water supplied come together and, together and by mixing, pass into a glass or a beaker 8 with which the refreshing beverage thus formed can be removed.

  • Fresh water is supplied when there is a need for water refill in the storage container 6, namely by opening the shut-off valve 11.
  • the required water level within the storage container 6 is detected by a water level sensor 12 and evaluated for control purposes in order to actuate the shut-off valve 11.
  • the CO gas supply is regulated automatically by a pressure reducing / pressure control valve, not shown, connected upstream of the supply line 10, so that, for example, a pressure of 4 bar is built up in the storage container 6. This pressure is also used to ensure that the carbonated water is conveyed from the storage container via the shut-off valve 5, which is open as required, and through the flow rate regulator 7 into the mixing trough 2.

  • the carbonized water inside the storage container 6 is thus cooled to a temperature close to freezing point, the somewhat warmer zones due to the special physical characteristics of the water near the freezing point in the bottom region of the storage container 6 close to the dispensing opening, which passes through the housing of the electric motor 13 is passed. There is therefore usually no danger of icing in this area.
  • the ice jacket 18 also represents cooling capacity for the storage container 6, so that several portions of beverages can be dispensed with sufficient cooling for a short time without the cooling system having to provide the high cooling capacity otherwise required.
  • an additional measure can be used in particular in connection with the storage container 6.
  • This additional measure consists of a liquid line which is guided in a first section 20 with good thermal conductivity in the bottom region against the reservoir 6 and in a second region 21 inside the reservoir 6 helically around the circulation pump 14 and its drive otor 13 and from there leads to a shut-off valve 22, the outlet line of which opens into the mixing channel 3.
