The present disclosure is directed to systems and apparatus for grinding spices and grains. One system includes a mill for grinding a spice or grain material, comprising a body and a handle rotatably coupled to the body. The handle is also coupled to an input of a speed boost assembly. An output of the speed boost assembly is coupled to a grind assembly, which includes a rasp. The speed boost assembly is configured to cause the rotational frequency of the rasp to be greater than a rotational frequency of the handle.

Grinding device (1) for an automatic coffee machine, comprising: a support body (2); a lower grinder (3) and an upper grinder (4) arranged coaxially with respect to an axis (X) and delimiting a gap where the grinding is performed; a motor (21) for driving at least one of said grinders (3,4) in rotation about said axis (X); an adjustment ring nut (6) for adjusting the width of said gap having means for transforming a rotation thereof about said axis (X) into a translation of at least one of said grinders in the direction of said axis (X); and a gear for driving said ring nut (6) in rotation; where said gear comprises a toothed wheel arc (7) engaging a pinion (8), and a mechanism for fixing said toothed wheel arc (7) in an adjustable position on said ring nut (6).

A coffer grinding and dosing device (12) comprises: a collection chamber (16) for containing coffee beans, underneath which a grinding zone (14) comprising a grinder (18) operated by an electric motor (20) is provided. The device is characterized in that the collection chamber (16) is positioned underneath the electric motor (20).

The invention relates to a beverage producing machine (1) comprising a housing (3) and a connector (20) for attaching an ingredient container (C) to said housing. The connector comprises a bottom wall (23) with a passage (25) for dispensing said ingredient towards the interior of the housing and a locking seat for said ingredient container. The locking seat comprises a ridge member (29) at least partly surrounding the bottom wall, wherein at least one resilient element (47, 49) is provided in said locking seat and constrained to the ridge member. The ridge member (29) is provided with at least one tangentially extending slot (39, 41) with an edge (39A, 41A) extending substantially parallel to and distanced from the bottom wall. The at least one resilient element projects from the edge of the slot towards the bottom wall (23) and is arranged to reduce backlash between an ingredient container and said connector when said ingredient container is locked to said connector.

A electronic grinder includes a main body and a grinding and dispensing chamber. The top of the main body open but covered by a cap. The main chamber includes a motor connected to a magnetically attached removable blade and propeller. The blade and propeller extend into the chamber when the grinder is assembled. When the cap is closed, the blade and propeller grinds material placed in the chamber and pull air down toward the blade and propeller. When the cap is opened, the blade and propeller function as a fan to generate airflow toward the top of the chamber to dispense ground material out of the chamber. The grinder can also include a microcontroller, a communications device, an infrared volume sensor, a scale, an audible buzzer, a vibration buzzer, and one or more sanitizing LED lights.

A coffee grinder having at least a flow channel that directs the ground coffee particles conveyed from the outlet of the grinder in order to transfer them to a container, and its inlet positioned right below the grinder outlet and connected to the grinder such that it can rotate according to the channel inlet axis that passes through the center of the inlet, and a motion control motor that successively moves the flow channel at the inlet axis in opposite radial directions in a suitable amount and frequency in order to prevent the sticking of the ground coffee particles located in the flow channel to the flow channel. A coffee machine having such a coffee grinder is also disclosed.

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.
