  • Patent number: 10667645
    Abstract: 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.

  • Patent number: 8424446
    Abstract: The present invention relates to a frothing device for the frothing of milk, comprising a steam supply channel which opens into a mixing chamber, a milk supply channel which opens into the mixing chamber and comprising an air supply channel, wherein the mixing chamber is connected in communication with a froth chamber. It is essential to the invention that the air supply channel opens into the froth chamber, with the result that an almost identical dispensing temperature of milk froth and milk can be achieved.

  • Publication number: 20080173180
    Abstract: 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.
