A carbonation unit which includes a carbonation chamber and an expansion chamber is employed for use in beverage dispensers. The carbonation unit also provides a process for carbonation of a beverage that includes reducing the pressure in the carbonation chamber to a dispensing pressure through the use of the gas expansion chamber.

1. A carbonation unit, comprising a carbonation chamber having a beverage inlet for introducing beverage into the carbonation chamber,a pressurized gas inlet for introducing pressurized carbon dioxide into the carbonation chamber,a gas expansion outlet at an upper end of the carbonation chamber, and
1. A carbonation unit, comprising a carbonation chamber having a beverage inlet for introducing beverage into the carbonation chamber,a pressurized gas inlet for introducing pressurized carbon dioxide into the carbonation chamber,a gas expansion outlet at an upper end of the carbonation chamber, anda carbonated beverage outlet; anda gas expansion chamber configured for expansion of gas therein, the gas expansion chamber linked to the gas expansion outlet through a sealable expansion link configured to selectively open and close, the gas expansion chamber linked to the gas expansion outlet to receive gas from an upper end of the carbonation chamber when the sealable expansion link is open without receiving carbonated beverage from the carbonation chamber effective to reduce gas pressure in the carbonation chamber. 2. The carbonation unit of claim 1, being configured for operating in a duty cycle comprising (i) a carbonation phase in which pressurized carbon dioxide is introduced into the carbonation chamber to produce a carbonated beverage, and (ii) an expansion phase, after conclusion of the carbonation phase, in which the expansion link is opened to reduce the gas pressure in the carbonation chamber. 3. The carbonation unit of claim 1 wherein the expansion phase causes the reduction of pressure to a dispensing pressure and the duty cycle comprises (iii) a dispensing phase in which the carbonated beverage is dispensed through the carbonated beverage outlet by the force of the dispensing pressure. 4. The carbonation unit of claim 1, wherein the expansion chamber comprises a draining outlet for draining liquid therefrom. 5. The carbonation unit of claim 3, wherein the draining outlet is opened at the end of or following the dispensing phase. 6. The carbonation unit of claim 2, comprising or being associated with a control module for controlling the duty cycle. 7. The carbonation unit of claim 1, wherein the pressurized gas inlet has a nozzle that, in use, is immersed in the beverage within the carbonation chamber. 8. The carbonation unit of claim 1, wherein the beverage outlet is positioned at a bottom end of the carbonation chamber. 9. The carbonation unit of claim 1, comprising an integral beverage cooling unit. 10. The carbonation unit of claim 9, comprising two concentric chambers in liquid communication with one another, of which a second chamber envelops a first chamber, one of said chambers being a cooling chamber and the other being said carbonation chamber. 11. The carbonation unit of claim 10, wherein said first chamber is the carbonation chamber and said second chamber is the cooling chamber, optionally wherein (i) the two chambers are separated by a heat-conducting wall, and/or (ii) the carbonation unit comprises a cooling element within said cooling chamber. 12. The carbonation unit of claim 10, wherein the expansion chamber is integral with the two concentric chambers. 13. The carbonation unit of claim 10, comprising an initialization vent for permitting release of residual gas from within the unit, optionally wherein the vent is linked to a duct that links the first and second chambers. 14. A process for carbonating a beverage, comprising: (a) introducing beverage into a carbonation chamber;(b) introducing pressurized carbon dioxide into the carbonation chamber under pressure and for a time sufficient to carbonate the beverage;(c) linking an upper end of the carbonation chamber to a gas expansion chamber to permit flow of gas from a head space formed above the beverage to the gas expansion chamber, thereby cause reduction in pressure within the carbonation chamber to a dispensing pressure; and(d) propelling the beverage out from the carbonation chamber, the propelling force being the dispensing pressure. 15. The process of claim 14, comprising repeating the steps sequence two or more times. 16. The process of claim 14 comprising cooling the beverage introduced into the carbonation chamber. 17. The process of claim 16, wherein the beverage is cooled prior to its introduction into the carbonation chamber, optionally wherein the beverage that is introduced into the carbonation chamber egresses from a cooling chamber. 18. A beverage dispenser, comprising a carbonation unit of claim 1.
