Definitions

  • the invention relates to a method and an apparatus for mixing beverage components of the type explained in the preambles of claims 1 and 3.
  • Such a method and such a device are known from DE-PS 31 32 706.
  • the known device is used to mix a smaller amount of syrup with a larger amount of water.
  • a receptacle is provided for each component, each of which is provided with its own feed line.
  • the receptacle for water is equipped with a level controller, which can be used to adjust the water volume.
  • the volume of the receptacle for syrup corresponds to the volume of the syrup to be mixed and is completely filled with every mixing process.
  • the syrup container is arranged below the water container and connected to the water container via a pipe through which the drain from the water container is guided. When the components are mixed, water and syrup are first introduced directly into their receptacles up to the predetermined fill level.
  • the inlet is then shut off and the water from the receptacle is piped into the syrup container and from there into a downstream collection container. Of the Syrup is thus rinsed out of the water in its receptacle. However, it has been found that the mixing results can still be improved with this device.
  • a device for mixing beverages is known in which the components are introduced directly into a common mixing container from below.
  • the mixing tank contains a float-controlled level indicator, which controls the opening and closing of the inlet valves for both components.
  • the smaller component is first introduced into the level container up to its predetermined level. Then the feed of this component is stopped and the water feed is opened, the water being led from below into the component introduced first.
  • the mixing result in this container can also be improved.
  • the device is specially designed for mixing a relatively free-flowing, water-like beverage concentrate (e.g. fruit juice concentrate) with water. Higher viscosity syrups would produce even poorer mixing results.
  • a float control for syrups can only be used to a limited extent, since the float sticks very easily due to crystallized sugar.
  • the invention is therefore based on the object of providing a method and a structurally simple device for mixing beverage components which are reliable in function and which provide improved mixing results.
  • the object is achieved in a method by the characterizing features of claim 1 and in one Device solved by the characterizing features of claim 3.
  • the arrangement according to claim 5 also cleans the transition area from remaining residual amounts.
  • the configuration according to the invention also makes it possible to use the tried-and-tested dosage via a receiving space which is to be completely filled, in particular for the syrup-like component.
  • the mixture of the two components becomes the first receiving space by means of the flow rate or the flow cross section of the feed which can be regulated according to claim 7 improved even further.
  • Claim 8 describes a first embodiment of a structural design and arrangement of both receiving spaces.
  • Claim 9 describes a second, preferred embodiment of a structural arrangement and configuration of the receiving spaces.
  • the cross-sectional area of the receiving space for the smaller component is expediently chosen to be smaller than the cross-sectional area of the receiving space for the larger component.
  • the transition area has the same cross-sectional area as the receiving space for the smaller component. In this way, interfering "dead corners" are avoided.
  • the cross-sectional area ratio between the two receiving spaces can be adjusted according to the desired mixing ratio of the components contained therein, so that the metering of both components is associated with an identical percentage error rate.
  • the configuration of claim 14 improves the filling of the second receiving space, wherein the filling accuracy can be increased by the measure according to claim 15.
  • FIG. 1 is a schematic representation of a flow diagram of a device 1 for mixing beverages G from two components, in particular a larger amount of water W and a smaller amount of syrup S.
  • the water W used for mixing first reaches a conventional water supply 2 with ventilation and injector pressure degassing, in which the water is freed from the dissolved oxygen.
  • the water supply 2 is state of the art and is therefore not explained further.
  • From the water supply 2 the deaerated water passes through a line 3 into two identically designed and parallel dosing and mixing units 4 and 4 '.
  • the syrup S is first fed via a line 5 and a valve 5a arranged therein into a storage container 6, the fill level of which can be checked via fill level indicators 7.
  • a syrup line 8 leads from the bottom of the syrup container 6 to each of the metering and mixing units 4, 4 '.
  • the dosing and mixing units 4 and 4 ' are identical, so that only the dosing and mixing unit 4 is explained below.
  • the reference numerals for the metering and Mixing unit 4 'entered which correspond to those of the dosing and mixing unit 4 explained and are supplemented by a prime.
  • the dosing and mixing unit 4 contains a first, larger receptacle 9, in the interior of which a first receptacle 11 with a predetermined volume is formed via a level meter 10.
  • a second receptacle 12 is arranged below the first receptacle 9, the entire interior of which is designed as a receptacle space 13 for a predetermined amount of the syrup S to be mixed.
  • the bottom of the upper container 9 is connected to the upper side of the lower container 12 via a pipeline 14 which can be shut off by a valve 14a.
  • the pipeline 14 has a smaller cross-sectional area than the receiving space 11 and forms a transition region between the two containers 9 and 12.
  • the bottom of the second container 12 is connected via a pipeline 15, which can be shut off by a valve 15a, to a collecting container 16, into which the corresponding one Line 15 'of the metering and mixing unit 4' opens.
  • the line 3 for water opens laterally into the lower region of the second container 12 via two shut-off devices 3a and 3b with mutually different flow cross sections.
  • the syrup line 8 also opens into the lower region of the lower container 12 via a shut-off valve 8a.
  • the collecting container 16 is connected via a line 17 to a device 18 for impregnating or treating the finished beverage with carbon dioxide, which is well known in the prior art and therefore not further explained.
  • This device 18 then becomes finished beverage G is pumped via a line 20 to a filling plant or the like.
  • all containers 2, 6, 9, 12 and 18 are connected to the carbon dioxide circuit, as indicated by the reference number 21 for all lines and devices carrying carbon dioxide.
  • a line system for cleaning liquid, in particular water, is also provided, the parts of which are identified by reference numeral 22.
  • valve 8a is first opened and the receiving space 13 of the receptacle 12 is completely filled with syrup S, the valve in the discharge line 21 also being open, so that the CO2 filling can be displaced. In the meantime, the valves 3a, 3b, 14a, 15a are closed. If the receiving space 13 is completely filled with the amount of syrup S corresponding to its volume, the valve 8a is closed and the valve 14a and the valve 3a, which enables a relatively large water throughput, to be opened. As a result, water flows via the line 3 from the water supply 2 into the receiving space 13 and in part presses the syrup therein through the pipeline 14 into the upper receiving space 11 the syrup mixes intimately with the water.
  • the water supply via the shut-off device 3a with the larger flow cross section is continued until one of the level indicators 10 reports that the total volume is about to be reached. Then the water supply is guided over the shut-off device 3b, which has a smaller flow cross-section, so that the liquid level in the receiving space 11 rises more slowly until the final level indicated by a higher level indicator is reached. In this way, the error is kept low by the necessary reaction and switching times when closing the water supply.
  • valve 15a is opened with the valve 14a open, so that all of the liquid in the containers 9 and 12 drains into the collecting container 16. A further mixing takes place. In addition, any syrup still adhering to the walls of the lower container 12 or the confluent pipelines is rinsed out.
  • FIG. 2 shows a dosing and mixing unit 40 which uses the dosing and mixing units 4 and 4 'in the device 1 of FIG. 1 and, analogously to these dosing and mixing units 4, 4' in the water line 3 ', the syrup line 8 ,
  • the carbon dioxide line 21, the drain line 15 with the valve 15a and a cleaning line, not shown, can be switched on.
  • the dosing and mixing unit 40 has a container 41 on the inside of which a first receiving space 42 and a second receiving space 43 are formed.
  • the first receiving space 42 has a larger cross section than the second receiving space 43 and is arranged above it.
  • the second receiving space 43 is connected directly to the first receiving space 42 via a transition opening 44, the cross-sectional area of the transition opening 44 being smaller than the cross-sectional area of the first receiving space 42 and being the same as the cross-sectional area of the second receiving space 43, at least in the upper one, of the same type Transitional opening 44 adjoining area.
  • the volume of the lower receiving space 43 is limited by a suitable fill level measurement, such as, for example, a high-resolution displacement sensor or viewing window with a light barrier or the like.
  • the total volume of the two receiving spaces 42 and 43 is limited either by the same or a separate, high-resolution displacement sensor 45 or by other, known level meters.
  • the ratio of the smaller cross-sectional area of the lower receiving space 43 to the cross-sectional area of the upper receiving space 42 is matched to the desired mixing ratio. In this way, each level measurement, both in the receiving space 43 and in the receiving space 42, is subject to the same error rate, so that the mixing accuracy is increased.
  • the cross-sectional ratio of the receiving spaces 43 to 42 can be approximately 1: 5.
  • the water W is introduced laterally into the second, lower receiving space 43 via two shut-off devices 3a and 3b with different flow cross sections from below.
  • the water W can initially be introduced quickly and slowly at the end of the filling process in order to improve the accuracy of the metering.
  • the syrup S is introduced from below, laterally into the second, lower receiving space 43 via two flow elements 8a and 8b for changing the flow rate. This means that the syrup can be introduced quickly and slowly before it reaches its desired level.
  • the syrup S is first introduced via the line 8 into the receiving space 43, first quickly and then slowly, until its predetermined filling volume is reached just below the transition opening 44. Then the syrup supply is switched off. Then the water W is introduced via line 3, first quickly, then slowly from below into the second receiving space 43. The inflowing water presses the syrup through the transition opening 44 into the first, upper receiving space 42, the mixing results being further improved by increasing the cross section. The water supply remains open until the predetermined total fill level is reached. After the water supply has been shut off, the valve 15a is opened and the liquid flows downward into the collecting container 16 in the manner already described.
  • the cross-sectional transitions lying downward in the flow direction are both in the metering and mixing unit 4, 4 'from FIG. 1 (not shown) also rounded off in the metering and mixing unit 40 of FIG. 2 (drawn). This applies in particular to the lower, outer boundaries of both recording spaces.
  • the receiving space 13 in the exemplary embodiment according to FIG. 1 can also be rounded at its upper, outer edges in order to facilitate the inflow of the liquid into the transition pipeline 14.
  • the flow rate of the syrup into the lower receiving space in FIG. 1 can also be regulated.
  • the transition areas can also be funnel-shaped or goblet-shaped.
  • other beverage components such as fruit juice concentrates or the like, can also be processed with the device according to the invention.
  • the device according to the invention can be modified in a simple manner, for example by using the second metering and mixing unit of FIG. 1 for mixing in a third, and further metering and mixing units for mixing in further beverage components. Three or even more recording rooms can also be connected in series.
  • the receiving spaces can, for example, also be arranged next to one another.
  • the device according to the invention can also be used if the syrup content exceeds the water content, if it is ensured that the water is sufficiently large Has pressure to be able to be pushed through the higher syrup column.
  • a (smaller) component of water can first be introduced into the lower receiving space, through which a (larger) component, for example fruit juice concentrate, is then passed.
