A method for producing a coffee beverage in a coffee machine including: a brewing device having a brewing chamber that receives ground coffee and includes a fluid inlet and a fluid outlet; a fluid system having a fluid feed line connected to the inlet and a fluid conveyor conveying a heated fluid through the feed line. The method includes: (a) introducing ground coffee into the chamber, (b) conveying heated fluid through the feed line into the chamber for brewing the ground coffee in the chamber and dispensing the beverage through the fluid outlet. Before step (a), heated fluid is fed through the feed line into the chamber and at least a part of this heated fluid is dispensed through a drainage outlet separate from the fluid outlet and fluidly communicating with the chamber and/or the feed line, to preheat the feed line and the brewing device before beverage preparation.

A beverage preparation machine for brewed beverages includes a housing having a housing wall that surrounds an inner space and has an opening; a brewing device arranged in the inner space for brewing a quantity of a solid material accommodated by the brewing device, wherein the quantity of the solid material can be output from the brewing device; a movable container for receiving a quantity of the solid material output from the brewing device, which container can be brought into the inner space through the opening; a movable cover plate for covering the opening, which cover plate in a first position covers at least one region of the opening, and which in a second position uncovers the opening. The cover plate is connected to the housing via a pivoting device so that the cover plate is movable between the first and second positions by pivoting about a pivot axis.

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 generating a coffee beverage in an automatic coffee machine brewing device supplies pressurized brewing water at a brewing device brewing water inlet according to a first brewing water supply mode during a first time period. During a second time period, a brewing water parameter is determined correlating with the volume flow and/or pressure of the supplied brewing water. A mode adjustment variable is set for a second brewing water supply mode using the brewing water parameter. Brewing water is supplied at the brewing water inlet during the second time period according to the second brewing water supply mode. The mode adjustment variable defines at least one continuous mode for the second brewing water supply mode, in which the brewing water is continuously supplied, and a pulse mode for the second brewing water supply mode, in which the brewing water is supplied in pulses.

A method for cleaning and/or disinfecting a milk-carrying system of a coffee machine for producing coffee mix drinks, and a coffee machine for carrying out the method has the aim of allowing the entire milk-carrying system to be cleaned, completely and in a way that can be easily automated. The milk delivery line is separated from the milk container, for carrying out the cleaning Process, and is connected to a first container, and a second container is arranged under a milk outlet of a milk preparation device of the milk-carrying system. Fluid is then delivered to fluid inlet in order to convey the active cleaning and/or disinfecting substance through the milk delivery line and a milk outlet into the second container. Thereafter, water is conveyed to the air inlet and the fluid inlet is closed, in order thereby to flush the milk-carrying system.

An automated coffee machine grinder features two grinding bodies that are rotatable relative to one another about a rotational grinding axis using a driveshaft device as well as an output opening for ground material arranged laterally of the grinding elements. The driveshaft device is positioned divergent from the rotational grinding axis. The output opening and the driveshaft device can be positioned differently relative to one another.

A dispensing apparatus for a milk-frothing device is indicated, comprising a body that is composed of a first part () and of a second part (), which comprises an emulsion chamber () for forming emulsified fluid, a fluid inlet (-) for letting a fluid into the emulsion chamber (), and a discharging region () having at least one dispensing opening () for discharging the emulsified fluid formed in the emulsion chamber (). With the aim of improving the sealing properties between the first part () and the removable second part (), the dispensing apparatus () according to the invention makes provision that at least one region of the emulsion chamber () and the fluid inlet (-) are formed in the first part () and that the second part () has the discharging region () having the at least one dispensing opening (), that the first part () is composed of a first material at least in a first region (), that the second part () is composed of a second material at least in a first region (), and that the first region () of the first part () and the first region () of the second part () are connecting regions that are respectively complementary to each other, at which connecting regions the first region () of the first part () and the first region () of the second () are connected in such a way that they can be disconnected from each other.

Within a brewing unit for a coffee machine, a brewing chamber, which is arranged in a pivotable brewing cylinder, can be filled with ground coffee powder by using a filling device. For the purpose of introducing the coffee powder, the brewing chamber has a filling opening. With the aim of avoiding undesired deposits of grounds in the region of the upper side of the brewing unit, and also of improving levels of hygiene, a projection extends in the filling direction outside the brewing chamber, wherein the projection is such that the exit region of the filling device is introduced with the formation of an interspace between the projection and a side wall of the exit region such that the projection substantially fully surrounds the exit opening of the exit region. Coffee powder supplied in the filling device drops from the exit opening of the exit region, directly through a through-opening of the projection and the filling opening, into the brewing chamber without striking against the projection.
