Method for the preparation and distribution of a hot chocolate drink, wherein a dose of the liquid which forms the drink is heated to a predetermined temperature and a dose of a preparation containing chocolate is dispersed in the dose of heated liquid, wherein the dose of liquid is heated by making a flow of steam with a constant flow rate flow for a predetermined time into a flow of the said liquid which forms the drink, which also has a constant flow rate. The method can advantageously be implemented by a device comprising a source of water vapour, a source of liquid for the formation of the drink, a distributor proportioning device for a preparation containing chocolate, and a chamber for mixing this preparation with the liquid for formation of the drink. The device includes a pipe for supply of the liquid for formation of the drink, between the said source of liquid and the said mixing chamber, pumping means and calibrated choke means which are disposed on this pipe and generate a flow of liquid with a predetermined constant flow rate, a pipe to supply steam between the source of steam and a point of confluence inside the said pipe to supply the liquid for formation of the drink, disposed between the said calibrated choke means and the said mixing chamber, the said pipe for supply of the steam being provided with means for interception and calibrated choke means which can determine a flow of steam with a predetermined constant flow rate. |
