<p>The invention concerns a gravity-feed unit dispensing cool drinks from a carboy comprising a breakable inner seal, comprising means supporting the upside-down carboy via its neck, which is centred on a striker, the latter comprising a discharge passage for the carboy communicating with a coiled pipe to cause the beverage to flow through a secondary exchanger, whereof the heat transferring agent has been previously cooled in a primary exchanger and brought to the secondary exchanger by a pump whereof the actuation is controlled by thermostatic means measuring the temperature of the heat transfer agent in the secondary exchanger. The primary exchanger comprises a heat source to cause the heat transfer agent to pass continuously inside a closed circuit mutually connecting the primary and secondary exchanger, even when the pump is inoperative.</p> |
