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.

A method for use of an apparatus comprises: a grinding step, a cleaning step, and a de-ionizing step; the apparatus comprises a receptacle to contain the product to be ground and provided with an unloading aperture; a fixed grinder; a mobile grinder rotatable around a rotation axis connectable to a drive motor; a cleaning device connected to the mobile grinder; a grinding chamber in which the fixed grinder, the mobile grinder and the cleaning device are located and provided with a discharge aperture to discharge the ground product.

A grinding system for grinding raw material to obtain ground material comprises a housing, a grinding assembly, and a first cap. The housing defines a grinding chamber, and the grinding assembly comprising a plurality of burrs. The grinding assembly is supported relative to the housing such that each of the plurality of burrs is arranged within the grinding chamber. The first cap is detachably attachable to the grinding assembly such that, with the first cap attached to the grinding assembly, rotation of the first cap relative to the housing causes rotation of at least one of the plurality of burrs relative to at least one other of the plurality of burrs and, with the first cap detached from the grinding assembly, the raw material may be arranged within the grinding chamber.

The present invention relates to a dispensing and preparation apparatus for powdered food or beverage products, the apparatus comprising a dispensing device (60) and an associated preparation or extraction device (70); the dispensing device (60) comprising one or more housings for receiving one or more containers (10, 20) with a powdered food or beverage product; the dispensing device (60) comprising a reader (62) to obtain the information of the product parameters of the powdered food or beverage products from the one or plurality of containers (10, 20); the dispensing device (60) further comprising a control unit configured to dispense a certain amount of powdered food or beverage product from each container (10, 20) according to these product parameters and/or according to a recipes database (64) as a function of the beverage to be prepared; the dispensing device (60) further comprising an encoder (63) to encode the beverage information on programmable identification means (65) on a product holder (61) in the dispensing device (60), to where the dispensed powdered food or beverage product is sent; the preparation or extraction device (70) being configured for receivingthe product holder (61) and comprising reading means (72) to identify the beverage information in the said product holder identification means (65), the extraction device (70) further comprising a control unit to extract the beverage according to the beverage information retrieved from the product holder (61) and/or from the beverage information retrieved from a beverage database in this control unit. The invention further relates to a method for dispensing powdered food or beverage products and preparing a beverage from them using a dispensing and extraction apparatus as the one described. The invention also relates to the use of a dispensing and extraction apparatus as the one described for delivering a certain beverage from powdered food or beverage products.

A coffee grinding machine (10) and an espresso coffee machine are described. The coffee grinding machine comprises a first grinder and second grinder cooperating with each other so as to grind coffee beans, obtaining a first dose of ground coffee during a first grinding cycle. The coffee grinding machine comprises a motor which rotates one of the grinders relative to the other one at a rotation speed. The coffee grinder machine is configured to modify the rotation speed so as to perform a second grinding cycle in which a second dose of ground coffee is obtained. The rotation speed is modified depending on quantitative information received from the espresso coffee machine and based on a coffee preparation cycle performed with said first dose of ground coffee, wherein the quantitative information may be a flow value measured in the espresso coffee machine or a brew ratio value.
