Definitions

  • the present invention relates to a device for cooling beverage components in a vending machine with a preparation and / or storage container for a first beverage component, in particular for carbonated water, and a storage space for receiving at least one container for another to be mixed with the first beverage component Beverage component, wherein a cooling system is arranged for the controlled cooling of the preparation and / or storage container for the first beverage component.
  • a mixed drink in vending machines in which a mixed drink can be provided, for example by mixing carbonated water with beverage concentrates, it is necessary, or at least to a great extent, to provide a container in which the carbonated water is kept ready or the water is carbonized. The cooler the water, the greater its absorption capacity for CO2 gas.
  • the volume fraction of the carbonated water is a multiple of the volume fraction of the beverage concentrate, so that the temperature of the carbonated water is also essentially determining the temperature of the soft drink.
  • the cooling of the carbonated water has a natural limit set by the freezing point of the mixture.
  • part of it is stored in ice form.
  • the ice sheet that forms is evaluated as a criterion for the cooling supply.
  • the carbonated water is preferably provided by cooling coils of a compression refrigeration machine. Such systems at least currently have the highest efficiency of the cooling systems or cooling elements in question.
  • the beverage concentrates it is also expedient to also cool the beverage concentrates to be added to the carbonated water for the provision of soft drinks, for two reasons.
  • the first reason can be that the shelf life of the beverage concentrates is ensured by the cooling measure, or at least is prolonged to a very great extent.
  • the second reason is that the heat capacity of uncooled beverage concentrates and further disruptive influences during the mixing and dispensing process can result in a temperature of the finished soft drink that is above the desired beverage temperature limit.
  • measures have also become known in connection with vending machines with the aid of which both the stored components are cooled for the preparation of a soft drink.
  • the evaporator branch of the compression refrigeration machine is guided into both areas and preferably divided and acted upon in such a way that the two beverage components to be mixed together can be cooled independently of one another in a controlled manner.
  • This takes into account, among other things, the fact that the temperatures and the cooling requirements for the two beverage components are different.
  • the temperature of the carbonated water should be in the area of the freezing point and, if necessary, an ice sheet should be formed to provide cooling capacity
  • the temperature of the beverage concentrate should be so high that after the mixing process the soft drink provided has the desired temperature as constant as possible.
  • the known arrangements are complex and expensive to produce.
  • a post-mix beverage dispensing device has become known in which the storage space for the beverage concentrates is connected directly to the container for the carbonated, cooled water and is cooled from this area.
  • cooling plates are provided which bring about an even cooling distribution.
  • the object of the invention is to provide a device for cooling beverage components in a vending machine, which is as simple as possible in terms of construction and control technology and ensures that both the first beverage component contained in a preparation and / or storage container with a high temperature constancy and the lowest possible temperature than the other beverage components to be admixed with this first beverage component, which are arranged in a storage space within containers, on the other hand, are cooled in stages accordingly.
  • a device which meets these requirements is characterized in accordance with the invention in that in a preparation and / or storage container in which the cooling of the first beverage component takes place with the formation of an ice area forming on the walls, the heat conducting element is flat on walls lying outside this ice area this preparation and / or storage container is flanged and guided into the wall area of the storage space for the further beverage component.
  • the processing and / or storage container for the first beverage component is cooled in a controlled manner by a cooling system that provides cold.
  • Compression refrigeration machines are particularly suitable for this purpose, the evaporator section of which, in the form of cooling tubes, is placed around the walls of the processing and / or storage container or is introduced into this container.
  • a sensor is arranged in the container, via which the cooling system is controlled according to the required cooling requirement. Since the cooling for this preparation and / or storage container is designed in such a way that part of the carbonated water is frozen, for example as an annular ice sheet in the lateral wall area, the invention provides for the heat-conducting element to be flanged to the container in the area outside the frozen beverage component part. While the area in which the ice forms is subject to different, and in fact significantly different, temperature fluctuations during the cooling and heating cycles, the area in which the stored beverage component remains in the liquid state is of very high temperature constancy.
  • This temperature gradient also promotes the need for the stocked first beverage component to remain liquid in the area in which the heat-conducting element is flanged flat. It is therefore expedient to lay this area in such a way that the dispensing opening for the first beverage component also lies at this point, thereby ensuring that the dispensing of this beverage component is not disturbed by ice formation.
  • the heat-conducting element is preferably guided flat in the wall area of the storage room in which the dispensing point of the further beverage component is located. This ensures that the beverage component quantities dispensed from the containers arranged in the storage room for the provision of beverages each have the low temperature which is jointly responsible for the final beverage temperature.
  • the storage temperature for these other beverage components, namely beverage concentrates, can easily be slightly, i.e. are a few ° C above this output temperature.
  • the heat-conducting element itself to form wall parts of the storage space.
  • a material, in particular a metal material, with good thermal conductivities is preferably used as the heat-conducting element.
  • heat pipes for heat conduction.
  • the figure shows a simplified representation of an arrangement in a vending machine with a carbonator, from which a heat-conducting plate is guided into the area to the storage room for beverage concentrates
  • a carbonator 2 is arranged in a device insulated housing 1 of a vending machine by a thermally insulated jacket 3. Via a feed line 4 this carbonizer 2 is supplied in a known manner as required water from a water supply and 5 CO2 via a feed line. Within this Karbo nisators 2, the supplied water is mixed with the supplied CO2 to carbonized water. Via cooling coils 6, which together with a compressor 7, a condenser section 8 and a throttle 9 form a compressor cooling machine, the carbonator 2 is cooled in such a way that an annular ice sheet 10 is formed on its side walls. The thickness of the ice sheet is detected by a sensor, not shown. Depending on this thickness of the ice sheet 10 to be detected by the sensor, the compressor 7 is activated.
  • An outlet opening 11 for the carbonized water is arranged in the lower region of the carbonator 2.
  • this carbonized water is dispensed via a mixing area, to which a beverage concentrate is also fed, for the production and provision of a soft drink.
  • the beverage concentrate 13 is stored inside in a container 14, which is inserted into a storage space 15 of the device housing 1. Via a drive system, also not shown, the beverage concentrate 13 is dispensed via the dispensing system 16 of the container 14 and mixed with the carbonated water, so that a soft drink is provided.
  • a heat-conducting element 17 is flanged and led as wall parts 18 and 19 of the storage space 15 into the area of the container 14 for the beverage concentrate 13. From the carbonator 2, the beverage concentrate 13 is thus subjected to an essentially uniform cooling, since - stabilized by the ice sheet 10 - the carbonized water in the flange area of the heat-conducting element 17 on the carbonator 2 is essentially constant at a temperature near the freezing point.
  • the heat-conducting element 17, which is flanged onto the carbonator 2 retrospectively supports that in this area, into which the outlet line 11 opens, the carbonized water remains liquid and ice formation does not form at this point.
  • the heat-conducting element 17 is also surrounded from the surroundings by heat-insulating material 20, which is symbolically represented by the hatching.
  • a heat gradient is formed within the container 14 for the beverage concentrate 13, which is to be indicated by the dashed lines.
  • the coldest areas are due to the conditions in the area of the wall parts 18 and 19 of the storage space formed by the heat-conducting element and thus also at the dispensing point for the beverage concentrate.
  • the storage room 15 can be opened in the operating direction of the housing of the beverage dispenser by a hinged or swing-open door flap 21, so that the container 14 for the beverage concentrate 13 can be removed and can be re-equipped with the same or a different beverage concentrate by a new storage container.
  • two or more concentrate containers can be arranged side by side in the storage space 15.
