DESCRIPTION:
BRIEF SUMMARY
The invention relates to a process and a device for mixing beverage components.
Such a process and device are known from DE-PS 31 32 706. The known device serves for mixing a smaller amount of syrup (first component) with a larger amount of water (second component). A measuring chamber of its own is provided for each component. The measuring chamber for water is provided with a filling level meter, via which the water volume is proportioned. The measuring chamber for the syrup corresponds in its volume to the syrup volume necessary for one batch and is completely filled for each mixing process. The measuring chamber for syrup is disposed below the measuring chamber for water and connected with it via a pipeline. During mixing of the components, water and syrup are at first introduced into their measuring chambers up to the predetermined level or up to the predetermined volume. Thereafter, the inlets are locked, the water is supplied from its measuring tank into the measuring tank for syrup via the pipeline, and both components are supplied from there into the collecting chamber connected downstream and mixed.
With a simple, clear-cut design, a batch-wise mixing of two beverage components can be achieved with relatively great accuracy with this known device. However, this is only the case if a sufficient quantity is present in the storage chamber for the syrup in order to make a complete filling of the measuring chamber for syrup possible. However, if the storage chamber only still contains an insufficient residual amount with the syrup supply running low or after the switching off of the syrup supply due to closing hours or a change-over to another beverage, either no processing is possible at all or the residual amount is provisionally ascertained by filling in water, an the required amount of water is added by means of tables and many manual interventions. Here, an exact observance of the mixing ratio is not possible and the quality of the beverage suffers from this.
The conditions in a process and a device according to the older German patent application P 41 14 673.5 are similar. In this device the measuring chamber with a specific volume for the syrup is combined to a receiving chamber for the complete amount of mixture with the measuring chamber with a filling level meter for the water, which is disposed above the same forming an enlargement of the cross-section enhancing a thorough mixing. A fixed filling level probe is disposed in the upper area of the measuring chamber for the syrup which defines the specific volume of the measuring chamber. During normal operation, syrup is first introduced into the lower measuring chamber until the fixed filling level probe is reached. Thereafter, water is also introduced into the lower measuring chamber, where a mixing with the syrup is already carried out until a specific amount of mixture recorded by the filling level meter is reached. This amount of mixture is then discharged into a collecting chamber through a pipeline connected to the lower side of the lower measuring chamber with a repeated thorough mixing.
Problems occur in this device, as well, if the syrup in the storage chamber is no longer sufficient for a complete filling of the measuring chamber.
The invention is based on the object of providing a process and a constructionally simple device for the batch-wise mixing of beverage components, with which partial amounts of the first components, whose volume is smaller than the volume of the measuring chamber can also be rationally processed with a constantly high mixing accuracy.
An exact observance of the desired mixing ratio is always possible by means of the exact measurement according to the invention of the residual amount of the first component, which is filled into the measuring chamber, with subsequent exact metering of the second component irrespective of the quantity of the residual amount contained in the storage chamber. Small residual amounts of the syrup or the like, whose economic processing has not been possible so far, can consequentl
