The present application relates to the technical field of grinding, and in particular to a grinding device, which solves the problems of poor stability and high energy consumption of a grinding device in the prior art. The grinding device provided in the present application comprises a housing, a grinding mechanism and a motor in the housing; the grinding mechanism comprises a male grinding head and a female grinding head, the male grinding head is rotatably fitted in the female grinding head, the motor is provided with a driving shaft, the male grinding head is connected to the motor by means of the driving shaft, the housing is provided with an adjustment mechanism for adjusting the position of the female grinding head. The grinding device has a simple structure, a reasonable layout, simple and convenient operation, and low energy consumption.

A unit of a coffee apparatus, in particular a coffee machine for brewing a coffee drink, includes a coffee bean container for storing the coffee beans, a portioner for portioning the coffee beans for an individual portion, and a grinder for grinding the portioned coffee beans. The coffee bean container and the portioner are formed in a common container module. The unit has a module receptacle, by which the container module can be connected during use and removed after use, and the container module has settings for a portion amount and a degree of grinding, which can be selected by the user. The portion amount setting influences the portioner and the degree of grinding setting influences the grinder. A simple, cost-effective and easy-to-use information exchange module between coffee container and coffee apparatus is thereby created.

A control unit, a pump for supplying infusion water, a boiler for heating the infusion water, an infusion unit, a coffee mill, and a user interface including a selector for a beverage and/or a ground coffee dose. The coffee mill has a hopper for coffee beans, a rotating and a non-rotating grinder, a motor for directly or indirectly driving the rotating grinder, all with capability to adjust the distance between the grinders. A first sensor detects a number of turns and/or speed of the motor and/or of the rotating grinder. A second sensor detects a distance between the grinders. The control unit stores an algorithm for calculating a correct dose of ground coffee, configured to receive the value of ground coffee selected and the distance between the grinders to automatically generate the number of motor turns necessary to obtain the correct dose of ground coffee.

An apparatus for dosing coffee beans for the purpose of selecting a metered quantity to be ground comprises a portioning device with a metering chamber having a receiving volume for receiving the coffee beans. The receiving volume is variable. Preferably, the setting of the metered quantity is performed mechanically, wherein the effect of the settings on the portioning device takes place mechanically. Preferably, the apparatus comprises a setting ring for manually adjustment of the metered quantity

A coffee grinder device includes a tank of coffee beans, at least one grinding member adapted to grind a quantity of coffee beans to obtain a coffee powder, a grain size adjustment device adapted to adjust at least one operating parameter of the grinding member to vary the grain size of the coffee powder, and a dispensing opening adapted to deliver the coffee powder towards a container adapted to receive the coffee powder.

The coffee grinder device also includes in correspondence with or downstream of the dispensing opening, an optical grain size sensor adapted to intercept the coffee powder exiting the dispensing opening and to generate at least a signal indicative of the grain size of the coffee powder. The grain size of the coffee powder is selectable by the grain size adjustment device on the basis of the signal indicative of the grain size of the coffee powder.

A spice mill having a container and having a grinder which includes a stator connected to the container, in which a position of the stator, when connected, is substantially defined in the direction of a longitudinal axis of the grinder relative to the container; an actuator, which has a rotor arranged at least in portions within the stator and is mounted rotatably relative to the stator. The rotor is connected for conjoint rotation to an actuating element and the actuating element is rotatably connected to an adjusting element and is secured in the direction of the longitudinal axis. The adjusting element has a thread by which it can be connected to the container such that the position of the rotor is adjustable in the direction of the longitudinal axis by a rotation of the adjusting element relative to the container.
