Machine for coffee-based beverages

Machine for coffee-based beverages, the machine comprising:

• a hydraulic pump adapted to generate pressurized water, as a function of the values of a configuration signal;
• a hydraulic circuit adapted to transport the pressurized water;
• a volume flowmeter configured to measure the volume of the pressurized water dispensed during a dispensing cycle of a dose of a coffee-based beverage and generate a volume measurement signal indicating said measure of the volume of the pressurized water;
• a processing unit configured to:
• receive a pressure dispensing profile signal indicating the trend of the configured pressure of the pressurized water during the dispensing cycle;
• as a function of the volume of the water dispensed during the dispensing cycle, wherein said dispensing profile signal comprises a first volumetric portion having a first pressure trend in a first volumetric interval and comprises a second volumetric portion having a second pressure trend in a second volumetric interval;
• generate the configuration signal as a function of the first pressure trend during the first volumetric interval so as to drive the hydraulic pump and generate the pressurized water;
• receive the volume measurement signal indicating the measure of the volume of the pressurized water at the end of the first volumetric interval and detect that it is smaller than the volume of the dose;
• generate the configuration signal as a function of the second pressure trend during the second volumetric interval so as to drive the hydraulic pump and generate the pressurized water;
• receive the volume measurement signal indicating the measure of the volume of the water at the end of the second volumetric interval and check whether it is equal to the dose volume.
