ABSTRACT OF THE DISCLOSURE A coffee machine includes a grinding mill, a proportioning cham- ber arranged adjacent to the outlet of the grinding mill and a processing chamber, into which the coffee powder from the pro- portioning chamber is discharged. The coffee powder coming from the grinding mill is thrown into the proportioning chamber, which includes a pressure sensitive, elastically resilient wall element with a signal generator connected thereto. As soon as the proportioning chamber is filled with coffee powder, a dy- namic pressure is built-up within the proportioning chamber due to the overpressure caused by the grinding mill, which forces the wall element to a displacement, whereby the signal genera- tor is operated. Subsequently, on the one hand, the motor of the grinding mill is switched off and, on the other hand, a bot- tom wall part of the proportioning chamber is unlocked, whereby the milled product, assisted by the elastically resilient wall element, is discharged from the proportioning chamber.
