Abstract

A beverage dispensing assembly for preparing and dispensing a beverage has a source of pressurized base liquid containing dissolved CO 2 , N 2 or N 2 O and a gas pressure of at least 0.5 bar overpressure at 2° C. A beverage unit with a liquid flow path has a liquid inlet at one end in fluid communication with the base liquid in the base liquid source and a beverage outlet at an opposite end. An ingredient container receiving slot has an ingredient container installed so the contents are in fluid communication with the liquid flow path for mixing the contents with a base liquid in the liquid flow path. A gas pressure regulation unit has a pressure chamber in the liquid flow path downstream of the communication between the liquid flow path and the ingredient container contents. A gas ingredient inlet is in fluid communication with the pressure chamber.

First claim

The invention claimed is:

1. A beverage dispensing assembly for preparing and dispensing a beverage the assembly comprising:
a source of pressurized base liquid having CO 2 , N 2 or N 2 O dissolved therein and having a gas pressure of at least 0.5 bar overpressure at 2° C.;
a beverage unit with a liquid flow path having a liquid inlet at one end in fluid communication with the base liquid in the source of base liquid by means of a valve and a beverage outlet at an opposite end;
an ingredient container receiver having an ingredient container wholly installed and contained therein such that when correctly installed, the content of the ingredient container is in fluid communication with the liquid flow path for mixing the content of the ingredient container with a base liquid in the liquid flow path;
a gas pressure regulation unit having a pressure chamber provided in the liquid flow path downstream of the fluid communication between the liquid flow path and the content of the ingredient container; and
a gas ingredient inlet in fluid communication with the pressure chamber through a valve, the gas ingredient inlet introducing pressurized CO 2 , N 2 or N 2 O in the pressure chamber in the liquid flow path in a direction opposite the liquid flow path.

2. The assembly according to claim 1 comprising:
a device for measuring the amount of dissolved and/or entrained gasses in the beverage, said measuring device configured to measure the amount of dissolved and/or entrained gasses in the beverage at a location along the liquid flow line downstream of the fluid communication between the ingredient container content and the liquid line, and upstream the gas pressure regulation unit.

3. The assembly according to claim 1 comprising a microprocessor and actuator configured to control operation of the valve provided at the gas ingredient inlet in the gas pressure regulation unit based on input received from a measuring device.

4. The assembly according to claim 1 , wherein the gas ingredient inlet is coupled to a pressurized gas source.

5. The assembly according to claim 4 , wherein the gas in the pressurized gas source comprises at least one of CO 2 , N 2 or N 2 O.

6. The assembly according to claim 5 , wherein the gas ingredient inlet is coupled to a source of food-grade carbonates or acids capable of generating carbon dioxide when reacted in the presence of water.

7. The assembly according to claim 2 comprising a microprocessor and actuator configured to control operation of the valve provided at the gas ingredient inlet in the gas pressure regulation unit based on input received from the measuring device.
