Abstract:
A machine for producing and dispensing cold or iced beverages comprising a plurality of beverage-containing tanks, each provided with beverage temperature sensors and density sensors, an evaporator of a refrigerating circuit and a mixer, the evaporators being connected with one and the same compressor by means of connection and controlled-shutoff valves, characterized in that it comprises a control system receiving information from said sensors about the beverage temperature and/or density in each tank and sending enable or cut-off signals respectively to the valves, which signals are distributed cyclically and in time so as to have a sequential enable of the valves, in each enable sequence each valve being enabled for a time which is a function of the difference between the beverage temperature and/or density detected in the associated tank and a predetermined density and/or temperature to be reached in such a tank.
