Patent number: 10667645Abstract: A milk-frothing device may be provided that comprises a mixing chamber which is constructed such that, when the milk flows through the mixing chamber, shear forces act on the milk and lead to mechanical lysis of the proteins contained in the milk and hence effect improved frothing-up of the milk. A drinks preparer may be provided that includes this milk-frothing device. A method may be provided for frothing-up of milk using this milk-frothing device.Type: GrantFiled: March 7, 2016Date of Patent: June 2, 2020Assignee: WMF GROUP GMBHInventors: Peter Arndt, Sander Dollner, Jochen Gussmann, Armin Startz, Thobias Kuchler

Publication number: 20080173180Abstract: A machine for the preparation of a hot drink with a housing and a brewing chamber, wherein the housing is provided with a connection region through which the brewing water is passed to the upper part of the brewing chamber. In order to seal the inflowing brewing water against the environment at the connecting point between the housing and the brewing chamber in a simple, economical and wear-resistant manner without complex locking mechanisms being needed, a seal is inserted into the upper part of the brewing chamber, wherein the seal and the connection region are automatically pressed together when the brewing chamber is inserted into the machine such that the connecting point between the connection region and the upper part of the brewing chamber is sealed against the environment.Type: ApplicationFiled: January 9, 2008Publication date: July 24, 2008Applicant: WMF WURTTEMBERGISCHE METALLWARENFABRIK AGInventors: Cornelius Boerner, Sander Dollner, Armin Startz
