Patent ID: 8721168

Claim:
A homogenizer device for dispersing and/or homogenizing liquid to viscous substances, having comprising: a container having one or more openings for introducing the substances to be processed, which substances are mixed in the container to form a liquid to be processed, whereby the container has an opening; a processing unit disposed in a central region of a bottom of the opening: at least two gear rims, disposed at least partially in said opening of said container and which can be driven independent of one another, and which are disposed concentrically and configured in circular shape, and are separated from one another by way of a predetermined interstice, whereby the substances are guided from a central region, through the interstice, into a peripheral region of the gear rims; a conveyance device disposed upstream from the gear rims disposed in the processing unit, which device conveys the liquid in a direction of the gear rims, under pressure, whereby the conveyance device is configured as an inducer screw comprising: two to four partly overlapping vanes; wherein at least one of the at least two gear rims comprises a counter-current rotor comprising an inner and an outer row of teeth, which are disposed concentric to one another, and the teeth of at least one of the rows of teeth of the counter-current rotor are disposed at an angle that differs from 0 degree, with reference to a tangent of the other row of teeth, in such a manner that a liquid pressure is produced in a direction towards the row of teeth that is located in a center of the gear rim; wherein the two gear rims each have a plurality of concentric rows of teeth, whereby a first group of rows of teeth acts as a rotor, and a second group of rows of teeth acts as a counter-current rotor that can be driven to rotate opposite to the rotor; wherein one or more of the rows of teeth of the counter-current rotor is positioned above the rows of teeth of the rotor and firmly coupled to the inducer screw.
