Abstract
The beverage preparation unit comprises a mixing chamber having a beverage outlet, a liquid flow path for supplying a liquid to the mixing chamber, and an air flow path for supplying air to the liquid flow path. The mixing chamber is arranged for receiving a beverage related ingredient, such as concentrate, preferably from an exchangeable supply pack. The liquid flow path is arranged for generating a hollow jet of liquid having an outer liquid portion extending in a flow direction of the jet and an inner air portion extending in a flow direction of the jet wherein the outer liquid portion surrounds the inner air portion.
Claims33
A beverage preparation unit for preparing beverage consumptions using a beverage related ingredient;
- wherein the beverage preparation unit comprises a mixing chamber having a beverage outlet, a liquid flow path for supplying a liquid to the mixing chamber, and an air flow path for supplying air to the liquid flow path;
- wherein the mixing chamber is arranged for receiving a beverage related ingredient;
- and
- wherein the liquid flow path is arranged for generating a hollow jet of liquid having an outer liquid portion extending in a flow direction of the jet and an inner air portion extending in a flow direction of the jet wherein the outer liquid portion surrounds the inner air portion;
- and
- wherein the liquid flow path extends in an axial direction, wherein the unit is further provided with air injection means for generating a flow of air which extends in the axial direction and for injecting the flow of air coaxially in a flow of liquid in the liquid flow path wherein the flow direction of the flow of liquid in the liquid flow path is the same as the flow direction of the flow of air so as to obtain the hollow jet.
A beverage preparation device for preparing beverage consumptions, the device comprising:
- a beverage preparation unit,
- wherein the beverage preparation unit comprises a mixing chamber having a beverage outlet, a liquid flow path for supplying a liquid to the mixing chamber, and an air flow path for supplying air to the liquid flow path;
- wherein the mixing chamber is arranged for receiving a beverage related ingredient, such as concentrate, preferably from an exchangeable supply pack;
- and
- wherein the liquid flow path is arranged for generating a hollow jet of liquid having an outer liquid portion extending in a flow direction of the jet and an inner air portion extending in a flow direction of the jet wherein the outer liquid portion surrounds the inner air portion;
- wherein the liquid flow path extends in an axial direction, wherein the unit is further provided with air injection means for generating a flow of air which extends in the axial direction and for injecting the flow of air coaxially in a flow of liquid in the liquid flow path wherein the flow direction of the flow of liquid in the liquid flow path is the same as the flow direction of the flow of air so as to obtain the hollow jet;
- liquid supply means including the liquid flow path for supplying a liquid to the mixing chamber;
- and
- air supply means for supplying air to the liquid flow path.
