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 milk foaming device for improving the quality of a milk foam (13) which is produced. The milk foaming device (1) has a mixing chamber (3) in which air (6) and milk (7) can be foamed by a steam flow (9) to provide the milk foam (13). For this purpose the respective flow rates of an air stream (15) and of a milk stream (8), each of which flows into the mixing chamber (3), are set by the air (6) and the milk (7) always flowing together into the mixing chamber (3) through an adjustable, variable opening cross-section (10) which acts as a flow rate reducer for the air stream (15) and the milk stream (8).

Abstract: A fully automatic coffee machine (1) including a detachable water tank (5) that is retained by a magnetic holding force on a base device (2) of the fully automatic coffee machine (1).

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: For a milk delivery device (1) which delivers milk (7) on the basis of the Venturi effect with the aid of a steam flow (9) output from a steam nozzle (2), it is provided, by corresponding orientation of an admixing opening (4) and optionally with the aid of deflecting surfaces (46), to allow a milk flow (8) sucked up by the steam flow (9) to flow tangentially onto the steam flow (9) in order thereby to be able to still ensure that the milk flow (8) is delivered in a manner as free as possible from disturbances, even in the event of very low flow rates of the milk flow (8). For this purpose, even before the milk flow (8) enters into contact with the steam flow (9), the milk flow (8) is oriented in the direction (51) of the steam flow (9).

Abstract: 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.

Abstract: 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.

Abstract: A drinks preparation machine for preparing a drink can be operated in multiple operational modes and includes a liquid container, a drinks preparation device for preparing the drink using a liquid, at least one fluid line which is connected to the liquid container and drinks preparation device, a receiving device for receiving a liquid filter in a predetermined filter position, a sensor for detecting a liquid filter, and a control device which controls a supply of a liquid from the liquid container into the fluid line. The control device is designed to prompt a liquid to be supplied into the at least one fluid line as a function of the signal of the sensor. In at least one of the operational modes, the liquid supply can be prompted independently of whether a liquid filter is placed in the predetermined filter position, and in at least one other of the operational modes, the liquid supply cannot be prompted when a liquid filter is placed in the predetermined filter position.

Abstract: 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.
