embodiment

The invention will be explained in more detail below with reference to an embodiment. In the accompanying drawing show:

Pig. 1: a schematic representation of the metering section in a carbonating and mixing machine;

Pig. 2: the conical diaphragm metering device as a sectional view «,.

The device for producing COg-containing soft drinks by adding additives consists of a metering, the units, not shown, such as water supply, venting, carbonation, upstream cooling and also not shown units such as COg supply, mixing, cleaning, etc. are arranged downstream. For metering, a water intermediate boiler 1 with a product water supply line 2 with centrifugal pump 3 and a syrup intermediate vessel 4 with a syrup supply line 5 are provided. Both intermediate boiler 1; 4 are level controlled and have a discharge line 6; 7 with shut-off valves 8; 9 ·

In the discharge line 7 from the syrup intermediate boiler 4, a conical diaphragm metering device 10 is arranged downstream of the shut-off valve 9. The exhaust pipes 6; 7 are then brought together to form a delivery line 11, which extends to a mixing line and a percolation beverage 12. In the delivery line 11, a centrifugal pump 13 is arranged. On the gas side, the intermediate water boiler 1, the syrup intermediate boiler 4 and the finished beverage boiler 12 by a CC ^ line 14, which is respectively attached to the boiler upper parts, in conjunction, creating in all three boilers 1; 4; 12 equal pressure or differential pressure to the boiler 12 is present and thus a centrifugal pump

can be used, which - then generates an always constant flow. By the same pressure in the boilers 1; 4; 12 or the differential pressure to the boiler 12 and the constant flow rate produced by the conical diaphragm meter 10, a constant mixing ratio of water and syrup by the syrup is added to the water.

For this purpose, a pipe 16 is inserted in an elbow 15 of the discharge line 7 of the syrup intermediate boiler 4, which is arranged axially to the conveying part 17 of the angle piece 15 and has an output 18. To the supplying part 19 of the-angle piece 15, the tube 16 has an opening 20. In this tube 16 is rotatably mounted a hollow cylindrical aperture piece 21 in seals 22. The aperture piece 21 has each offset by 120 ° three holes 23, which have different diameters and are arranged centrally to the opening 20 of the tube 16 and thus also centrally to the feeding part 19 of the angle piece 15. The diaphragm piece 21 is led out of the tube 16 and has there a rotationally mounted adjusting ring 24, corresponding to the three holes 23 has three locking recesses 26 for a resiliently mounted in the tube 16 ball 27 on "To Peindosierung ist.weiterhin an axially adjustable Dosierkegel 28 available , which is mounted centrally in the diaphragm piece 21 and the respective bore 23 limited in its diameter. The cylindrical shaft 29 of the Dosierkegels 28, which is guided centrally in the diaphragm piece 21, has on a portion of a fine thread 30 which engages in a corresponding fine thread in the diaphragm piece 21 "The shaft 29 of the Dosierkegels 28 is led out of the diaphragm piece 21 and the adjusting ring 24 and there has a scale 32 for displaying the fine adjustment on «For reading the scale 32, a bracket 34 is present, which is attached to the diaphragm piece 21.

The mode of operation of the device is as follows:

The intermediate water boiler 1 is through the centrifugal pump 3 to

filled to a certain level with preferably deaerated water. Likewise, the intermediate syrup vessel 4 is filled with syrup via the syrup supply line 5 up to the intended level. From both intermediates, 1; 4, the liquids through the centrifugal pump 13 through discharge lines 6; sucked off, the discharge lines 6; 7 are merged before the centrifugal pump 13 to only one delivery line 11, so mix the product water and the syrup. The dosing of the syrup is carried out by the conical diaphragm metering device 10, which is arranged in the discharge line 7 for the syrup. The in the discharge lines 6; 7 provided shut-off valves 8; 9 are necessary for starting and shutting down the machine. They prevent emptying of the intermediate boiler 1; 4 and ensure an exact dosing ratio in all operating conditions. Since the boiler 1; 4; 12 are all connected to each other by a COp line 14, there is the same pressure or differential pressure across the liquids. This makes it possible to use a high-performance, high-performance centrifugal pump with a constant flow rate, and on the other hand guarantees a mixing ratio to be determined in each case. The controlled metered addition of the syrup is effected by the adjustment of the conical diaphragm metering device 10. In this case, a coarse adjustment is made by the rotation of the diaphragm piece. By pressing the lever 25, the diaphragm piece 21 is rotated so that through one of the three holes 23, which have different diameters, the syrup is conveyed * The diaphragm piece is thereby locked by the ball 27 and locking recess 26. A fine adjustment is carried out by the rotation of the knurled nut 33 and thus the shaft 29 of the Dosierkegels 28. If the shaft 29 is rotated, this moves through the fine thread 30; 31 in the axial direction and the metering cone 28 increases or decreases the flow area of the respective bore 23 * Thus, the conical diaphragm dosage exact adjustment of the syrup supply and thus the mixing ratio is given.
