Abstract: 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.

Abstract: A grinding device includes: first and second grinding elements, the first grinding element being rotatable relative to the second grinding element around a rotary axis for grinding coffee beans between the grinding elements into a powder; a carrier wheel rotatable around the rotary axis for conveying powder on the carrier wheel to an outflow channel to output the powder; a housing surrounding the grinding elements and the carrier wheel and including the outflow channel, the second grinding element being stationary relative to the housing, a rolling bearing with inner and outer rings and rolling elements therebetween, the outer ring being stationary on the housing and the first grinding element, the carrier wheel and the inner ring being rotatable around the rotary axis together. An annular seal ring seals an intermediate region above the outer ring around the rotary axis between the carrier wheel and the outer ring.

Abstract: A dispensing apparatus for a milk-frothing device is indicated, comprising a body that is composed of a first part (10) and of a second part (50), which comprises an emulsion chamber (15) for forming emulsified fluid, a fluid inlet (15-1) for letting a fluid into the emulsion chamber (15), and a discharging region (55) having at least one dispensing opening (61) for discharging the emulsified fluid formed in the emulsion chamber (15).

Abstract: A beverage outlet for a beverage preparation machine, for example for a coffee maker, may include an outlet tube, one end of which can be connected to the beverage preparation machine and the other end of which may have an outlet opening for dispensing a beverage from the beverage preparation machine. The beverage outlet furthermore may have a beverage guide element, which runs coaxially to the outlet tube and a first section of which is arranged inside the outlet tube and a second section of which projects out of the outlet opening of the outlet tube. Provision is made for the outlet tube to have at least one notch, which extends frontally from the outlet opening-side end of the outlet tube opposite to the beverage dispensing direction (D) and which forms a passage opening between inner and outer area of the outlet tube.

Abstract: 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.
