MISCHKOPF ZUM AUFSCHAEUMEN EINES STOFFES MIT EINEM GAS

摘要

The description relates to a mixing head for foaming a substance with a gas, e.g. a dairy product with nitrogen. The mixing head has a rotor with coaxial circles of teeth arranged in radially and axially staggered array. The substance to be foamed thus passes through the mixing head both radially and axially, whereby the teeth of the circles arranged axially one behind the other can become finer with increasing proximity to the exit aperture. The mixing head is preferably formed in several stages, i.e. within a rotor/stator stage the toothed circles have the same axial position with no axial offset.
