Browning unit to reduce residual water during the rinsing process and operation of a brewery unit

摘要

brewery unit for a beverage preparation device with a brake chamber adjustable by means of a drive or adjusting device between different operating positions (2),which is equipped to receive a beverage residue, in particular ground coffee powder, via an opening (7) of the brewery chamber (2) and with a brew head (5),at least in a breastfeeding position and a rinsing of the chamber (2) into the opening (7) of the chamber (2),Preferably with an anterior fracture piston (8),is at least partially introduced and has a fluid outlet (18) which is designed to be operated in conjunction with a pressure or pressure valve (19), which, when reaching a limit pressure within a closed fracture chamber (2), opens and allows the flow of fluid from the fracture chamber (2), the pressure or pressure valve (19) with a mechanical opening mechanism (26) for the forced opening of the pressure or pressure valve (19) independent of the pressure in the fracture chamber (2) is trained in cooperation;so that when the flushing is achieved, the pressure or pressure valve (19) is transferred to a pressure independent forced opening position.
