Abstract: A coffee brewer contains a brewing unit in which coffee grounds having been poured in are compressed by a plunger driven by an actuator. Heated water flows through the compressed coffee grounds. A control device controls the actuator in accordance with signals of an angle of rotation sensor. The control device first moves the plunger against a stop in an ejection position to calibrate the sensor, then moves the plunger by a predetermined distance in a downwards direction into a pouring-in position. Afterwards the control device moves the plunger by a second distance into the brewing position, a length of the predetermined distance and the second distance corresponds to a number of pulses of the sensor which are stored in the memory. The control device subsequently moves the plunger by a third distance back into the ejection position in which the coffee grounds are removed from the plunger.

Abstract: A method for the dispensing of a hot beverage in a beverage vending machine, comprising a hot water generating system for the generation of hot water and a brewing chamber, wherein the brewing chamber is filled with brewing material for brewing a hot beverage, and following this, is loaded with hot water via a hot water inlet, and after the brewing process, the hot beverage is delivered from the brewing chamber into a vessel via a hot beverage outlet and a drain line connected therewith, wherein the hot beverage outlet can be loaded with compressed gas from a compressed gas source during a brewing process. Also includes a device for carrying out the method.

Abstract: A device for the removal of coffee foam from coffee liquid, comprising a tank having a tank interior, which is bounded by a peripheral tank wall as well as a tank bottom, with an inlet arranged above the tank bottom, via which the tank interior can be filled with coffee liquid, as well as with a liquid outlet arranged at the base of the tank bottom, from which the coffee liquid that has been freed of coffee foam can be discharged from the tank interior, is characterized in that the tank bottom converges toward the liquid outlet in a funnel-like manner and has a plurality of peripheral steps, which are arranged one above the other in a terrace-like manner, each of which has a peripheral step face and a vertical step wall arranged at an angle to it, the two of which
