Method for the instantaneous self-calibration of the dose of coffee, for a grinder-doser apparatus with electronic control provided with a weighing means and with a granulometry adjusting means with a warning microswitch. The method provides: a first setting of the nominal dose with temporary grinding times; a second setting of the tolerance and reliability ranges of the dispensed doses, for the purpose of recalculation; the automatic control of the weight of each actually dispensed dose; the automatic recalculation of the grinding times according to an ordinary calculation logic, when one detects three consecutive out-of-tolerance doses all within the positive or negative reliability range, or according to a forced calculation logic when the microswitch detects a granulometry variation; automatic calibration of the apparatus according to the recalculated times.

A coffee machine, preferably a fully automatic coffee machine, as well as a method for operating such coffee machine are provided. The coffee machine includes a coffee bean supplying unit comprising a plurality of coffee bean containers, a grinding unit comprising a single grinder, a selecting unit for selectively connecting one of the coffee bean containers to the grinder, a brewing unit comprising a single brewing chamber, and a dispensing unit. Thanks to the provision of a single grinder and of a single brewing chamber, the coffee machine has an extremely compact construction, while being capable of preparing a variety of different coffee-based drinks thanks to the provision of a plurality of coffee bean containers.

An autonomous beverage maker, system and method for fresh brewed coffee, tea, and other beverages, responsive to sensed demand or inputted command, makes an initial beverage extract concentrate in a turbulent manner under unpressurized conditions, and then a dilute/secondary extract under pressurized conditions and mixes the initial extract and dilute to complete a beverage batch, successive secondary extracts/dilutes being made as required or desired to meet flavor, strength, etc., successive batches being rapidly made as required to meet demand, maintain level, etc. A parameter or parameters within a receiving or dispensing container is/are autonomously monitored to determine level, demand for additional beverage, beverage age, and or/other information, and responsive to the monitored information or an inputted command, the beverage maker autonomously adapts the beverage making operation or executes predetermined steps, such as, but are not limited to, making more or fewer beverage batches, or signals to dispose of existing beverage.

Automatic process for calibrating the single and double dose of ground and dispensed coffee by means of a specific grinder-doser integrating a weighing device with a load cell. The process is automatically and steadily carried out during the ordinary activity, with no interruptions, adapting the grinding time according to the actually detected grammages, in order to get closer as much as possible to the desired grammage in any use condition. The process, after a preliminary phase for temporary configuring the desired grammages and the grinding time, conceives self-calibration cycles continuously repeated, each of them comprising three sequential phases: a first phase for automatically checking the dispensing with progressive weight detections, a second phase for automatically processing the detected data for determining the correct grinding time, a following third phase for the automatic setting.
