Abstract: A coffee machine includes a weighing system to measure the weight of the liquid coffee extracted in a cup and a coffee grinding machine having a weight system to measure the weight of the ground coffee dispensed in a filter-holder. The coffee machine has a control unit provided with a memory, wherein infusion ratios for different types of coffees are saved and the coffee grinding machine includes a control unit operatively connected to the control unit of the coffee machine to send information about the weight of the ground coffee contained in the filter-holder. The control unit of the coffee machine uses the information received from the coffee grinding machine to extract a coffee that satisfies an infusion ratio selected by the operator.

Abstract: A coffee grinding machine has a dispensing duct connected to a grinder unit to dispense coffee inside a filter supported by a filter-holder. The filter-holder is disposed above a support platform connected to a load cell that weighs the quantity of ground coffee contained in the filter and sends an indicative weight value of the ground coffee contained in the filter to a control unit in such manner to stop the grinder unit when the weight of the ground coffee contained in the filter-is equal to one dose. The load cell is inside a support frame that contains the grinder unit and an electric motor used to actuate the grinder unit.
