A bean grinding coffee maker to solve a sealing problem of a power outlet passage at a bottom of a coffee bean grinding device. The bottom of the coffee bean grinding device is provided with the power outlet passage. A brewing device is disposed under the power outlet passage and in communication with the coffee bean grinding device through the power outlet passage. A sealing component is disposed at an end opening of the power outlet passage to seal the end opening of the power outlet passage. A blocking plate is disposed between the sealing component and the brewing device, and is staggered with or presses against a bottom of the sealing component by means of moving to control the powder outlet passage to be communicated with or isolated from the brewing device.

A coffee bean feeder for feeding coffee beans coming from a coffee bean container to a coffee grinder and, more particularly, a coffee bean feeder for selectively feeding coffee beans coming from a coffee bean container among a plurality of coffee bean containers to a coffee grinder are provided. The coffee bean feeder has an inlet and an outlet, and a rotatable body provided with one or more dosing compartments. By rotating the body of the feeder about its longitudinal axis, a dosing compartment can be brought into alignment with the feeder inlet or with the feeder outlet or with neither of them. A selecting unit comprising one or more of such coffee bean feeders, as well as a coffee machine comprising the selecting unit, are also provided.

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.
