Abstract
The invention relates to a milk-frothing device with a dynamic mixing unit having a stator and a rotor which can be set in rotation relative to the stator, rotor and stator being configured such that milk and air can be conducted firstly to the dynamic mixing unit, subsequently, for frothing-up in the dynamic mixing unit, can be subjected multiple times to a shearing effect by rotation of the rotor relative to the stator and finally can be discharged out of the dynamic mixing unit.
Claims17
A milk-frothing device, comprising:
- a dynamic mixing unit having a stator,
- the stator having a series of shearing elements,
- the dynamic mixing unit having a rotor that is rotatable relative to the stator,
- the rotor having a series of shearing elements that engage intermittently with the shearing elements of the stator,
- the rotor and the stator being configured to:
- conduct milk and air to the dynamic mixing unit,
- froth the milk and the air in the dynamic mixing unit,
- subject the frothed milk and air multiple times to a shearing effect caused by rotation of the rotor relative to the stator such that rotation of the rotor relative to the stator is configured to shear and change direction of milk and air flowing between one series of shearing elements of the rotor and a directly adjacent series of shearing elements of the stator, and
- discharge the frothed and sheared milk and air out of the dynamic mixing unit.
