The present invention relates to a coffee machine equipped with a grinder that grinds coffee beans, and a mechanism that reduces ground beans on an inner peripheral wall of a chute. A hammer includes a striking member that abuts against a chute by an elastic force in an initial state, and a second holding member that sandwiches and holds a cup with the first holding member by the elastic force, and enters a striking preparation state in which the striking member is temporarily separated from the chute by pivoting from the initial state, the second holding member is disposed at a position where a distance from the first holding member is smaller than a thickness of an peripheral wall of the cup in the initial state, and the striking member applies an impact to the chute when the hammer returns from the striking preparation state to the initial state by the elastic force.

The present disclosure relates to a beverage or food brewing method and a beverage or food brewing machine. The beverage or food brewing method includes following steps: actuating a beverage or food brewing machine to produce powder through a grinding device and to output the powder to a powder holder; when the powder in the powder holder reaches a set amount, obtaining a first grinding time value T11 of the beverage or food brewing machine; according to the first grinding time value T11, obtaining a prolonged grinding time value T12 corresponding to the first grinding time value T11; making the grinding device continue operating for a period of time determined by the prolonged grinding time value T12 and outputting the powder from the grinding device to the powder holder.

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.

Grinding device, coffee machine and method for adjustment thereof. A grinding device (100) comprises a grinding housing (101) with mutually co-acting grinding bodies (110, 120). A lower of the two grinding bodies (110) is both driven and axially adjustable for the purpose of setting a grind size. An upper grinding body (120) is removable. A grind size of the grinding device can be adjusted in absolute manner between a first extreme position and a second extreme position, corresponding to a fixed setting range between a minimal clearance between the two grinding surfaces and a maximum clearance between the two grinding surfaces. An extreme position of the adjustable grinding body is imposed by a stop which is encountered by the adjusting means in the relevant extreme position. A coffee machine uses the absolute grind size and/or a fine-tuning for an optimal contact time between coffee and through-flowing water.

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.

The grinder includes a container having a discharge opening for material to be ground; first and second grinding tools, the first tool rotatable relative to the second grinding tool about a rotation axis for crushing the material in a gap between the tools. The second tool has an inlet channel limited by a wall section around the axis for supplying material into the gap and is moveable relative to the first tool axially to the axis. A collar seal between container and second tool has a through-channel for discharging material into the inlet channel and is stationary relative to the container so that a first annular collar seal section limiting the through-channel contacts the container and overlaps the second tool wall section toward the axis. The collar seal includes a second annular section connected to the first annular section via an elastic spring and supported on a contact surface.
