A machine for producing and dispensing cold or iced beverages comprises a plurality of beverage-containing tanks (11). Each tank is provided with an evaporator (12) for a refrigerating circuit and a mixer (13). The evaporators are connected with one and the same compressor (15) by connection and controlled-shutoff valves (16). The machine comprises a control system (22) receiving information (23, 24) about the temperature and/or density of the beverage in each tank and sending enable or cut-off signals respectively to the valves (16), which signals are distributed cyclically and in time so as to have a sequential enable of the valves themselves. In each enable sequence each valve is enabled for a time which is a function of the difference between the temperature and/or density detected in the associated tank and the predetermined density and/or temperature to be reached in such a tank.
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.
A method of operating 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 shut-off valves, the method comprising the cyclic steps of detecting information from said sensors about the beverage temperature and/or density in each tank and allocating each valve an operating time which is more or less long depending on the difference between the detected temperature and/or density for the associated tank and a predetermined density and/or temperature to be reached in such a tank.
