Abstract: The present invention relates to a mixing device for mixing a liquid, such as water, with an instant ingredient to form a beverage. The mixing device comprises a mixing chamber and a rotor which, during rotation about the axis of rotation, defines a surface of revolution extending along the circumference of the rotor. The rotor is arranged in the mixing chamber. The mixing chamber comprises a peripheral wall zone having a substantially circular cross section. The peripheral wall zone surrounds the surface of revolution. An outlet duct for discharging the mixture formed is connected to the mixing chamber. The inlet of the outlet duct is provided at the rotor. At least one rotor rib is provided at the peripheral wall zone. This rotor rib extends from the peripheral wall zone in the direction of the surface of revolution of the rotor.

Abstract: Preparing device for preparing a beverage from a powdery substance and a hot liquid, the device comprising: at least one mixing chamber for mixing a quantity of the powdery substance and a quantity of the hot liquid; an inlet into the mixing chamber for the quantity of hot liquid; an inlet into the mixing chamber for the quantity of powdery substance; an extractor hood placed on the mixing chamber; an extraction duct connected to the extractor hood and provided with a suction device, such as a ventilating fan, for extracting vapor and dust particles from the mixing chamber via the extraction duct and the extractor hood; a first housing accommodating further components of the preparing device, such as electrical components and pipework, in which the extraction duct extends entirely along the exterior of the first housing.

Abstract: The invention relates to a mixing device for mixing a liquid, such as water, with an instant ingredient to form a beverage. The mixing device comprises a mixing chamber and a rotor. The mixing chamber comprises an inlet chamber, a rotor chamber and a pipe bend. The inlet opening of the pipe bend extends in the horizontal plane. The rotor is provided in the rotor chamber.

Abstract: The invention relates to a filling level detection device for powdered material. The filling level detection device has a storage unit and a sensor. The storage unit has a container provided with a discharge aperture for discharging metered quantities of powdered material. The sensor has a light source for transmitting a light beam, and a detection unit for detecting a light intensity. A wall of the container at least in one zone is at least partially transparent to light transmitted by the light source. In addition, the sensor is placed outside the container in such a way that the light source directs the light beam onto the zone in the wall of the container, and the detection unit intercepts light reflected by the powdered material and emerging through the zone in the wall of the container. The light source and the detection unit are placed in one horizontal plane.
