An apparatus for carbonating and chilling a liquid comprises a closed vessel (1) having an inlet (2) and an outlet (3) for the liquid; an inlet (4) for carbon dioxide, which opens in the vessel below the surface of the liquid; and an outlet (7) for undissolved carbon dioxide in the liquid, which opens in the vessel above the surface of the liquid. A return conduit (8) is connected between the carbon-dioxide outlet (7) and the carbon-dioxide inlet (4). A compressor (9) is connected in the return conduit, and a chiller (10) is provided after the compressor for chilling the carbon dioxide compressed by the compressor. An expansion conduit (5) is arranged inside the vessel (1) and connected between the carbon-dioxide inlet (4) and the return conduit (8) to which it is connected by means of an expansion valve (6), such that the carbon dioxide compressed by the compressor (9) is evaporated and expanded in the expansion conduit. |
