Definitions
- the present invention relates to a device for preparing and dispensing soft drinks, one of a plurality of beverage concentrates and cooled water enriched with CO gas for the respective
- REPLACEMENT LEAF Drinking quality either supplied from the line of a water supply system or a storage container under sufficient pressure, the water supplied being able to itself be under pressure or being conveyed exclusively or additionally into the carbonator by a pressure pump.
- a check valve arrangement prevents a counter flow.
- the carbonizer is supplied with CO gas, specifically from a CO gas storage container via a pressure reducing valve.
- the cooling of the carbonator serves on the one hand to improve the carbonization and on the other hand as a prerequisite that the finally prepared and dispensed drink has the desired low and essentially constant temperature.
- the cooling of the carbonator is expediently carried out via a cooling system which is able to build up an ice jacket in the area of the side walls of the carbonator, which is formed to a certain extent by the circulated water.
- "cooling capacity" can be stored and the cooling system need not be designed to be extremely powerful, as would be necessary in the case of flow cooling.
- a shut-off valve is installed in a line connected to the bottom area of the carbonator opened and the cooled, carbonated water metered through a flow control valve fed to a mixing area, which is also fed the correspondingly metered amount of a desired beverage concentrate.
- the carbonated water can be brought individually to the delivery point for the individual concentrate or, for example, can be guided past all of the delivery points in succession via a so-called mixing channel. Merging different concentrates at one and the same mixing point is somewhat more problematic.
- the present invention is based on the object of expanding a device for preparing and dispensing CO-containing soft drinks with regard to their area of application, namely in terms of construction in terms of space and effort, but in terms of functionality without sacrificing quality for the prepared and dispensed soft drinks.
- a device for preparing and dispensing soft drinks is a so--called vending machine for post-mixed drinks, bility been extended in its Nutz ⁇ that with similar, more compact design and 'without any special storage of Grund ⁇ there are suitable liquid both the possibility as before, it remains to issue CO-containing soft drinks as
- the carbonated water is correspondingly cooled immediately from the carbonator. Cooling the carbonator in a known manner ensures that a sufficient amount of beverage portions has the desired reduced drinking temperature. If a CO-free soft drink is required, the water required for this purpose is led in the vicinity of the carbonator through the bypass to the dispensing point in the mixing area with the beverage concentrate and the cooling of this water is provided
- REPLACEMENT LEAF A similarly cooled soft drink with CO enrichment is ensured in that the bypass line for this water is led through the storage container (carbonator) and / or is guided past it with good thermal coupling from the outside. Both the temperature prevailing there and the "cooling capacity" made available there are used fully effectively without the need in principle for additional individual cooling measures or control measures.
- the water supplied through the bypass line similar to the licensed water, will have to be acted upon by a flow controller at the dispensing point.
- the user could be free to decide whether carbonated water or non-carbonated water should be added to a certain beverage concentrate.
- such an arrangement will preferably be equipped in such a way that when a certain soft drink is selected using a corresponding beverage concentrate from a plurality of available ones beverage concentrates, the assignment in the device is carried out in exactly the same way as the setting of the correct mixing ratio.
- the device according to the invention is characterized in that the bypass line led through the storage container within the storage container in its lower region by one in
- REPLACEMENT LEAF Reservoir arranged circulation pump is arranged.
- the bypass line which is coupled to the storage container from the outside with good thermal conductivity, is arranged in the lower region of the storage container with its wall in a thermally contacting manner. Because of the special behavior of water and also of carbonated water, it is achieved in this way that the bypass line is led in regions of the storage container which are slightly above freezing point.
- Icing within the bypass line is also effectively countered by the fact that the evaporator lines used for cooling and before the formation of an ice jacket within the wall of the storage container are arranged as a component of the cooling system in the upper region of the storage container, remote from the area of the bypass line.
- the device according to the invention is characterized in that a pump system circulating the bypass line content is arranged between the beginning and the end of the bypass line which is passed through the storage container and is guided past it by means of good thermal conduction from the outside. This also prevents a possible risk of icing within the bypass line.
- the content of the bypass line lying outside the actual cooling zone is kept in a constant cooling state, and this knowledge can be further developed in such a way that This outside area of the bypass line is made enlarged and thermally insulated.
- the circulation can be made dependent on the temperature in the bypass line, for which purpose a temperature sensor is required which acts directly or indirectly on the circulating pump system.
- branch system directly as a changeover valve.
- shut-off valve from the branch system to the carbonator and in the bypass line, these two valves being expediently opened alternately when required and at the same time being put into operation when the feed pump is required and is usually used.
- REPLACEMENT LEAF 1 shows a highly schematic arrangement for dispensing optionally CO-containing and CO-free refreshments.
- FIG. 3 shows an embodiment modified from the arrangement according to FIG. 2 and
- Fig. 4 shows a reservoir for carbonating water with an external bypass.
- FIGS. 1 and 3 each show arrangements in which a soft drink is prepared and dispensed in the area of a mixing trough 1 by mixing a selected beverage concentrate with chilled, non-carbonated or carbonated water.
- a shut-off valve 4 is opened at the same time or overlapping, so that 5 carbonated from a storage container
- REPLACEMENT LEAF Water which is treated and cooled there, is passed through a flow regulator 6 into the mixing trough 1 under pressure.
- this mixing trough 1 the dispensed beverage concentrate and the supplied carbonated water come together and, together and by mixing, pass into a glass or a mug 7 with which the refreshing beverage thus formed can be removed.
- the storage container 5 serves as a so-called carbonizer. Water is fed into it via a feed line 8 and CO gas via a feed line 9, each under pressure from above.
- the water pressure is generated by a pressure pump 10, which in the present case sucks the water from a water storage tank 11 when there is a need for water refilling in the storage tank 5 and sprays it into the storage tank 5 via a shut-off valve 12 which is then open.
- the required water level within the storage container 5 is detected by a water level sensor 13 and evaluated by control technology for the control of the pressure feed pump 10 and the shut-off valve 12.
- the CO gas supply is regulated automatically by a pressure reducing / pressure regulating valve (not shown) connected upstream of the supply line 9, so that, for example, a pressure of 4 bar is built up in the storage container 5. This pressure is also used to ensure that the carbonated water is conveyed from the reservoir via the shut-off valve 4, which is open as required, and through the flow rate regulator 6 into the mixing channel 1.
- a CO gas cushion is formed in the head region of the storage container 5, above the water stored therein.
- a gas pump 14 turns this gas cushion into CO gas
- REPLACEMENT LEAF mixes The water is also circulated and set in rotation in the storage container about a vertical axis around the intake pipe 16 for the CO gas.
- the stored, carbonized water within the storage container 5 is cooled, specifically via cooling coils 17 of a cooling system (not shown) arranged on the outside of the storage container 5.
- a cooling system not shown
- an ice jacket 18 is also formed on the side walls of the storage container in the area of these cooling coils 17, the thickness of which is detected by an ice sensor 19 and evaluated for controlling the cooling system.
- the carbonized water inside the storage container 5 is thus cooled to a temperature near the freezing point, the somewhat warmer zones because of the special physical nature of the water near the freezing point in the bottom region of the storage container 5 near the dispensing opening, which is through the housing of the Electric motor 15 is passed. There is therefore no danger of icing in this area.
- the ice jacket 18 also represents cooling capacity for the storage container 5, so that several portions of beverages can be dispensed with sufficient cooling for a short time, without the cooling system having to provide the otherwise high cooling capacity required for this.
- the corresponding valve system 3 is activated to add the beverage concentrate suitable therefor.
- the shut-off valve 4 remains closed, and instead a shut-off valve 20 is opened. Since the
- shut-off valve 20 If there is no water pressure from the reservoir 5, it is necessary that the pressurized water feed pump 10 is started at the same time as the shut-off valve 20 is opened. Since in this case the shut-off valve 12 is closed, the water is branched off in a branch point 21 and passed through the shut-off valve 20 opened in this case and a flow regulator 22 into the mixing channel, where it meets the selected beverage concentrate and is mixed gets into the beverage cup 7.
- the water supplied is first passed through water guide channels 23, which are thermally well coupled to the lower part of the storage container 5, and then through a pipeline 24, which runs around the circulation pump within the storage container 5 14 coiled.
- This measure serves to sufficiently cool the non-carbonized water required for the preparation of a drink without having to provide a separate cooling system for this.
- the cooling capacity of the ice jacket is also used in this way.
- the arrangement of the water delivery channels 23 and the pipeline 24 in the essentially ice-free areas of the storage container 5 also prevents the risk of icing in the latter. This risk can be countered by further measures.
- REPLACEMENT LEAF is circulated by a cold sensor in the water circuit.
- the arrangement of this feed pump 25 also opens up the possibility of providing a thermally insulated water guide, including a small storage tank, for the water outside the cooling section 23, 24, so that the quantity of water stored in a cooled state is increased.
- Such a small water tank 26 is indicated in the illustration according to FIG. 2.
- FIGS. 2 and 3 only the non-carbonized water is cooled within the storage container 5.
- the two representations also show measures in order to separate air trapped in the non-carbonated water in such a way that no air pockets within the system impair its functionality.
- the air separation according to FIG. 2 takes place by means of an air separator 27 which is located exclusively in the water guide for the non-carbonized water and by means of which the separated air can escape into the ambient atmosphere. Appropriate outlet valves which close when the liquid is wetted and open when it dries out are known.
- This air separator 27 can be formed into a correspondingly enlarged cooling water reservoir.
- FIG. 4 shows a storage container 5 with a water guide channel 23 lying exclusively on the outside in the bottom area on this thermally well-coupled water guide channel 23.
- a film heating element which is applied from the outside to the windings of the water guide channel. The risk of icing in these channels must therefore also be countered.
