The method for adjusting the quantity of coffee comprises the steps of: dispensing a predetermined quantity of coffee powder into an infusion chamber (); by means of an electric actuator (), closing said infusion chamber compressing the coffee powder in the infusion chamber. The method also provides for detection of at least one parameter of the electric actuator during at least a part of the step to close the infusion chamber and compress the coffee powder; and setting of the quantity of coffee powder dispensed in a subsequent dispensing cycle as a function of said parameter.

Method for automatic adjustment of the quantity of coffee and coffee machine using said method

A method for detecting an amount of grains within a container of a rotating grinding member is described, said method comprising the steps of: supplying (FORP) a first driving torque to the rotating grinding member during a first interval (T) of a grinding cycle (CM); &#x2014;having (CTMOO) a first value indicative of a period of rotation of said member at the first driving torque; supplying (RP) the rotating grinding member, during a second interval (T) of said cycle, with a second driving torque lower than the first driving torque; &#x2014;measuring (CTM) a second value indicative of the relative period of rotation of said member at the second driving torque, processing (CDTR, CNFR) the first and second values in order to generate information (ALR) indicative of the amount of grains being within the container.
