A grinder includes a connecting part configured to be attached to a rotating shaft to which a handle of a hand mill configured to grind food by hand is mounted; and a motor configured to rotate the connecting part and abut on the connecting part.

An automatic grinder and a grinding method thereof. The grinder includes a control structure and at least one material container assembly. The control structure includes a driving assembly and a connecting structure connected thereto. The material container assembly includes a material container body (20), a grinding head (22) fixedly connected to the material container body (20), and a grinding sleeve (25) rotatably connected to the grinding head (22). A recess (201) is provided on the material container body (20), engaged with the connecting structure. The grinding head (22) is fitted into the grinding sleeve (25), defining therebetween a material compartment (40) for accommodating a material. The driving assembly drives the material container body (20) to rotate. The material container body (20) drives the grinding head (22) to rotate. The grinding head (22) moves relative to the grinding sleeve (25), such that the material therebetween is ground into powder.

The present disclosure generally relates to devices and methods for brewing beverages. More specifically, aspects of the present disclosure include devices suitable for brewing coffee from coffee beans which have been ground by the device using a wet grinding process, and methods of brewing coffee using such a device.

A coffee machine equipped with a grinder that grinds coffee beans, and a blade that grinds the coffee beans can be replaced with a blade having a different pattern. A main body includes a drive source, first power transmission portions, and a gear portion (gear of a manual setting disc dial), a grinder unit is fitted into the main body, the grinder unit includes a second power transmission portion, and interlocking portions, and is detachable from the main body, and when the grinder unit is fitted into the main body, the second power transmission portion and the like are coupled to the first power transmission portions, and the interlocking portions are coupled to the gear portion (gear of the manual setting disc dial).

A unit of a coffee apparatus, in particular a coffee machine for brewing a coffee drink, includes a coffee bean container for storing the coffee beans, a portioner for portioning the coffee beans for an individual portion, and a grinder for grinding the portioned coffee beans. The coffee bean container and the portioner are formed in a common container module. The unit has a module receptacle, by which the container module can be connected during use and removed after use, and the container module has settings for a portion amount and a degree of grinding, which can be selected by the user. The portion amount setting influences the portioner and the degree of grinding setting influences the grinder. A simple, cost-effective and easy-to-use information exchange module between coffee container and coffee apparatus is thereby created.
