The invention relates to a method for dispensing ground coffee for preparing a coffee beverage. The method comprises the steps of: providing a machine (110), which comprises one or more receptacles (13, 14) for storing one or different types of roasted coffee beans, one or more dosing devices (60, 70) for dispensing coffee beans, which are stored in the one or more receptacles (13, 14), and a grinder (30) for receiving coffee beans, which are dispensed by the one or more dosing devices (60, 70), the grinder (30) being configured to move into different grinding positions for different grinding degrees, respectively; setting up the grinder (30) so that the grinder (30) is in a specific grinding position; dispensing, with the one or more dosing devices (60, 70), a specific amount of coffee beans to the grinder (30) subsequent to the step of setting up the grinder (30); and grinding, with the grinder (30), said specific amount of coffee beans and, thus, dispensing the so ground coffee beans until the grinder (30) is free from coffee beans.

A grinding device includes: first and second grinding elements, the first grinding element being rotatable relative to the second grinding element around a rotary axis for grinding coffee beans between the grinding elements into a powder; a carrier wheel rotatable around the rotary axis for conveying powder on the carrier wheel to an outflow channel to output the powder; a housing surrounding the grinding elements and the carrier wheel and including the outflow channel, the second grinding element being stationary relative to the housing, a rolling bearing with inner and outer rings and rolling elements therebetween, the outer ring being stationary on the housing and the first grinding element, the carrier wheel and the inner ring being rotatable around the rotary axis together. An annular seal ring seals an intermediate region above the outer ring around the rotary axis between the carrier wheel and the outer ring.

A grinding assembly for grinding a partially dried or a dried substance is described. The assembly include a first component, a second component, a chamber component, a disc component, a first magnetic component, and a second magnetic component. The first magnetic component maintains a magnetic connection with the second magnetic component to affix the first component to the chamber component. Upon user rotation of the first component, a first set of protrusions of the first component are moved such that the first set of protrusions engage a second set of protrusions of the chamber component to grind the substance. In response to such rotation, the substance is ground into a much thicker consistency that resembles a hand-broken consistency. The ground substance falls through a plurality of openings of the chamber component into the second component for storage.

A coffee grinder has a housing that includes a ring burr, a shaft extending through the ring burr to an end, the shaft having an axis of rotation, and a burr having an external surface, the burr having an internal bore that extends therethrough. The internal bore has a surface which is tapered with respect to the axis of the shaft. An interlocking plug is shaped to extend through the internal bore of the burr, the interlocking plug having a sidewall surface which is tapered with respect to the axis of the shaft, such that the sidewall surface abuts the surface of the burr to seat the interlocking plug within the burr. An adjustment knob engages the end of the shaft for locking the interlocking plug within the burr.

An electric motor operated kitchen appliance has a base unit having an electric motor and a preparation vessel, which can be connected to the base unit and into which a rotating element protrudes, which can be rotationally driven by means of the electric motor, wherein a grinding element, which, with a grinding area of a grinding vessel held on the preparation vessel, forms a grinder, can be connected to the rotating element. To advantageously further develop the kitchen appliance, the grinding element is connected to the rotating element via a coupling element having at least one elastic partial area.

An adjuster 3 is attached to a barrel unit 1 to be rotatable relative to the barrel unit 1 and to be prevented from coming off the barrel unit 1 in an axis direction. A ground particle size for granular food is adjusted by rotating the adjuster 3. A means is provided that inscribes an outer mill unit 4 in the barrel unit 1 and the adjuster 3, and makes the outer mill unit 4 movable in the axis direction and makes the outer mill unit 4 attachable and detachable. A rotary shaft 6 extending from a rotary operation unit 2 extends downward along a mill. An inner mill unit 5 is attached to the rotary shaft 6. The adjuster 3 is provided with a movement restricting means 44 that restricts movement of the inner mill unit 5 to a predetermined position. Releasing the restriction imposed by the movement restricting means 44 makes the inner mill unit 5 and the outer mill unit 5 extractable.
