A coffee machine including a grinder configured to grind coffee beans, and a coffee machine made to return a grinder falling into an abnormal state to a normal state. The grinder configured to grind the coffee beans by a predetermined rotation operation in the normal state, and an operation portion are provided, when the grinder is in the abnormal state (bean clogging state) in which the predetermined rotation operation cannot be performed, if the operation portion is operated, the reverse rotation operation is executed in a direction opposite to that of the predetermined rotation operation, and in the normal state, the reverse rotation operation is not executed even if the operation portion is operated.

The invention relates to a method and a device for treating granular grinding stock or grinding stock mixtures by way of controlled mechanical size reduction by means of a grinding mill or a combination of several grinding mills. The actual grinding process is controlled by externally provided data. The data is saved in a data memory unit that is connected to the packaging of the grinding stock, namely directly.

A coffee grinding machine (10) and an espresso coffee machine are described. The coffee grinding machine comprises a first grinder and second grinder cooperating with each other so as to grind coffee beans, obtaining a first dose of ground coffee during a first grinding cycle. The coffee grinding machine comprises a motor which rotates one of the grinders relative to the other one at a rotation speed. The coffee grinder machine is configured to modify the rotation speed so as to perform a second grinding cycle in which a second dose of ground coffee is obtained. The rotation speed is modified depending on quantitative information received from the espresso coffee machine and based on a coffee preparation cycle performed with said first dose of ground coffee, wherein the quantitative information may be a flow value measured in the espresso coffee machine or a brew ratio value.

A touch free, spice dispenser is provided including a container for holding spices, a holder for supporting the container on an external support, a grinding mechanism and a sensor for activating the grinding mechanism in response to the presence of an object. The container has an open end and a closed end. The holder includes an end cap for support of the container, a hook for engagement with a support member and a strap extending between the hook and the end cap. The grinding mechanism is positioned in the end cap of the holder and is in electrical communication with a contact pad located on the hook. The grinding mechanism includes a grinder plate and a motor to rotate the grinder plate in response to a signal received from the sensor. Holes in the grinder plate and apertures in the end cap allow for passage of the spices out of the dispenser. A support assembly is also provided for supporting the dispenser above a food item.

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.

An electronic grinder powered by a smartphone has an electronics housing removably attached to a container section. The electronics housing has a motor and a microcontroller powered by a smartphone connected by a universal serial bus connector. The container section is sealed at the top by an openable, swivel-mounted cap. The motor has a blade that extends into the container section. The blade connected to the motor by a magnetic connection and the blade is configured to grind material disposed in the container section when the container section is closed.
