A calibration tool for a coffee grinder can receive an image from a camera. The image can depict coffee grinds produced by the coffee grinder. The calibration tool can analyze the image using one or more image processing techniques to determine a representative grind size for the coffee grinds. The calibration tool can determine whether the representative grind size of the coffee grinds deviates from a predefined reference size by at least a threshold amount. In response to determining that the representative grind size of the coffee grinds deviates from the predefined reference size by at least the threshold amount, the calibration tool can output an instruction indicating how to calibrate the coffee grinder to more closely adhere to the predefined reference size.

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.

An upper part for a spice mill at least partly of a plastic material includes an upper cover surface with at least one opening, in particular a through-opening for ground spices, a circumferential lateral surface, and a milling element or a mounting for the milling element. A preferably elastically deformable snap-action element, by which the upper part can be rotatably connected to a lower part, is arranged so as to be flush with the opening in plan view.

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 machine, including a grinder configured to grind coffee beans, and a coffee machine made to remove waste, such as chaff, from a separation area, where the waste such as chaff is separated from ground beans. The coffee machine includes a first grinder configured to grind the coffee beans by grinding, a separation area where the waste is separated from the ground beans ground by the first grinder. And, the waste from the separation area is cleaned by wind pressure while the first grinder is in a stop state.

A grinder for a spice mill, in particular a hand-operated spice mill, having an inlet side for entry of unground grinding stock and an outlet side for the exit of ground grinding stock, including a rotor, a stator interacting with the rotor and a housing at least partially surrounding the rotor and/or stator. The housing includes a stator housing part, which is substantially rotationally fixedly connected to the stator, and a rotor housing part which is rotatable relative to the stator housing part and is substantially rotationally fixedly connected to the rotor via a connecting element. The connecting element is at least partially received in a recess in the rotor, and the connecting elements and the rotor are frictionally connected. The housing has, on a side of the rotor facing the inlet side, a blocking element which blocks displacement of the rotor in the direction of the inlet side.
