Device for producing and dispensing beverages mixed from milk with liquid flavoring agents
A device for producing and dispensing different beverages, which are mixed from milk and different flavoring agents. A mixing chamber ( 3 ) is provided, having a milk feed line ( 2 ) and a line ( 8 ) for discharging the milk-flavoring agent mixture. The device further has at least one reservoir ( 5 ) for receiving the flavoring agent (S 2, S 2, S 3, Sn), wherein each reservoir ( 5 ) is connected with a supply line ( 7 ) via a metering device or delivery pump ( 4 ) and a feed line ( 6 ) to the mixing chamber ( 3 ) of each flavoring agent (S 1, S 2, S 3, Sn) such that the flavoring agent (S 1 . . . Sn), which can be delivered into the mixing chamber ( 3 ) in a metered manner by means of the delivery pump ( 4 ), can be mixed therein with the milk, wherein the mixed beverage can be dispensed via the dispensing line ( 8 ).
1. A process for producing and dispensing different beverages, which are mixed from milk and at least one flavoring agent having a density higher than that of milk, comprising:
selecting at least one flavoring agent from amongst a plurality of flavoring agents, wherein each one of the plurality of flavoring agents is contained in a respective separate reservoir;
selectively pumping the selected at least one flavoring agent, via a respective delivery pump, from the reservoir connected to the pump directly into a mixing chamber via a respective flavoring agent feed line directly connected vertically upward from below the mixing chamber to a bottom surface of the mixing chamber;
delivering milk via a milk feed line, separate and distinct from the at least one flavoring agent feed line, into the mixing chamber;
mixing the selected at least one flavoring agent with the milk inside the mixing chamber to create a mixed beverage;
ending pumping of the selected at least one flavoring agent into the mixing chamber before stopping the milk supply to the mixing chamber to clean the mixing chamber by using a continued flow of the milk; and
dispensing the mixed beverage out of the mixing chamber via a dispensing line.
2. The process according to claim 1 , wherein the mixing the selected flavoring agent with the milk includes swirling and stirring the milk with the selected flavoring agent inside the mixing chamber.
3. The process according to claim 2 , wherein the mixing chamber includes perforated plates for swirling and stirring the milk with the selected flavoring agent.
4. The process according to claim 1 , further comprising cleaning the mixing chamber after the mixing is completed, using a control system which controls a time sequence of the milk supply and of the delivery of the selected flavoring agent.
5. The process according to claim 4 , further comprising cleaning the milk feed line, the mixing chamber and the dispensing line, by introducing steam or water into a branch line connected to the milk feed line, wherein a duration of the introduction of water or steam into the milk feed line and a time sequence between the milk supply and the cleaning is controlled by the control system.
6. The process according to claim 1 , wherein a plurality of selected flavoring agents is simultaneously added to the mixing chamber, each via a dedicated flavoring agent feed line feeding vertically upward through the bottom surface of the mixing chamber.
7. The process according to claim 1 , wherein a quantity of milk for cleaning the mixing chamber and the dispensing line is mixed into the mixed beverage after the mixing process is complete.
