Abstract
A homogenizer for homogenizing free-flowing substances, with a rotor which is mounted in a housing so that it can rotate and can be driven by a drive device. An element is mounted in the housing so that it can rotate and can be driven by a drive device independently of the rotor to homogenize and/or transport the liquid substance.
Claims13
A homogenizer for homogenizing a free-flowing substance, comprising:
- a housing;
- a rotor mounted for rotation in the housing and having a plurality of rotor blades disposed thereon;
- a drive device coupled rotate the rotor;
- a rotatable element coupled to the drive device and mounted for rotation in the housing, the rotatable element comprising a plurality of pump buckets and driven for rotation independent of the rotor to thereby homogenize and/or transport the free-flowing substance;
- and
- a plurality of stator blades disposed within the housing, at least some of the stator blades positioned between the rotor blades and the pump buckets.
