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 modular food dispensing device comprising a food container configured to contain and dispense a food product, a drive module for mechanically driving the food container to dispense the food product, and one or more magnets provided on one or both of the food container and drive module for releasably connecting the food container and drive module. The drive module is releasably connectable to the food container to selectively form a mechanical linkage for transmitting a driving force from the drive module to the food container to dispense the food product.

A grinding system for grinding raw material to obtain ground material comprises a housing, a grinding assembly, and a first cap. The housing defines a grinding chamber, and the grinding assembly comprising a plurality of burrs. The grinding assembly is supported relative to the housing such that each of the plurality of burrs is arranged within the grinding chamber. The first cap is detachably attachable to the grinding assembly such that, with the first cap attached to the grinding assembly, rotation of the first cap relative to the housing causes rotation of at least one of the plurality of burrs relative to at least one other of the plurality of burrs and, with the first cap detached from the grinding assembly, the raw material may be arranged within the grinding chamber.

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 coffee machine provided with a second grinder for grinding coffee beans, and provides a coffee machine that is controlled in consideration of a state for grinding coffee beans in the grinder. A coffee machine including a second grinder for grinding coffee beans, in which an input amount of coffee beans to be put into the second grinder is controlled.

A bean grinding apparatus including a body; grinding burrs mounted in the body, the burrs including a non-driven burr and a rotationally driven burr, the rotationally driven burr having a rotational axis about which it rotates; a drive motor operatively coupled to the rotationally driven burr; a grounds flow path defined within the body; and an exit spout, the exit spout having an inlet in communication with the grounds flow path and an outlet, wherein the exit spout defines a longitudinal axis and the longitudinal axis of the exit spout is angled with respect to the rotational axis of the driven burr.
