Abstract: A milk supply device for supplying milk from a milk supply container to a milk dispensing device is provided. The milk supply device comprises a milk transport line which can be connected to the milk supply container and with which milk which has been taken from the milk supply container can be delivered to the milk dispensing device. The milk supply device further comprises a three-way junction, which can be operated such that optionally milk can be transported from the milk supply container to the milk dispensing device, whilst the milk transport line is sealed off by it, at the same time, relative to the cleaning agent transport line, in a fluid-impermeable manner, or cleaning agent can be conducted from the cleaning agent transport line in the direction towards the milk dispensing device and/or in the direction towards a discharge of the milk supply device.

Abstract: A coffee machine for the preparation of pressure-extracted coffee with a low particle content is provided. The coffee machine differs from known machines for pressure-extraction of coffee by comprising a filter element for reducing the particle content of coffee, which filter element is disposed downstream of the percolating sieve and is connected fluidically to the percolating sieve and to the outflow. By means of the filter element, coffee extracted by pressure in the percolating unit can be filtered before dispensing the outflow so that suspended particles and emulsified oils of a specific size are separated from the coffee by the filter element and a new coffee is produced. In addition, the coffee machine can prepare standard pressure-extracted coffee since the coffee from the percolating unit can also be guided past the filter element, i.e. need not flow necessarily via the filter element to the outflow.

Abstract: A milk-frothing device may be provided that comprises a mixing chamber which is constructed such that, when the milk flows through the mixing chamber, shear forces act on the milk and lead to mechanical lysis of the proteins contained in the milk and hence effect improved frothing-up of the milk. A drinks preparer may be provided that includes this milk-frothing device. A method may be provided for frothing-up of milk using this milk-frothing device.

Abstract: The present invention relates to an espresso machine or a fully automatic coffee machine having a grinder and an infusion device comprising an infuser and an infusion chamber, which is characterized by a volume-determining portion designed to determine the ground volume of a defined quantity of coffee powder ground by means of the grinder, a mass-determining portion designed to determine the ground mass of this quantity of coffee powder, and a calculation portion with which, on the basis of a predefined correlation, which is stored preferably in the calculation portion itself, between the grain size distribution and/or the degree of grinding of ground coffee, on the one hand, and the mass and the volume or a variable derived from these two variables, in particular the density, of ground coffee, on the other hand, there can be calculated from the determined ground volume and from the determined ground mass, the grain size distribution and/or the degree of grinding of this quantity of coffee powder.

Abstract: A coffee machine (1) having a coffee grinding device (9), a brewing device (5), a brewing water source (7) and a flowmeter (8), which for the user offers a particularly simple setting of the extract content of a coffee beverage. A display device (16) is provided for displaying the flow rate acquired on the flowmeter (8).

Abstract: A grinder for a coffee machine includes a first grinding disc disposed in a housing. A drive moves the first grinding disc about a rotational axis. A second grinding disc is disposed in the housing. There is a threaded part in which the second grinding disc is attached. The threaded part is screwable into the housing. A drive wheel is disposed coaxially with respect to the threaded part and rotates the threaded part with respect to the housing. A grinding gap between the two grinding discs is thereby able to be set. A setting wheel co-operates with the drive wheel, the setting wheel being attached to the housing. A supply opening is disposed in the housing for supply of coffee beans to be ground. A path guide opening guides away the coffee ground between the two grinding discs. A holder is adjustably attached to the housing and is fixable in any position.
