Mixing or pumping apparatus for the treatment of flowable thin or highly viscous media

摘要

Arrangement for the treatment of fluent, thin and highly viscous media, particularly for the fermentation of micro organisms, for mixing, pumping and the dissipation of the medium. The arrangement is based on a novel principle of bladeless mixing and pumping of fluent media of any kind and density. The main part of the arrangement is a hollow rotor with a bottom with at least a single inlet opening in the bottom. The rotor is rotated at a speed at which the treated medium due to centrifugal forces proceeds from one end of the rotor to the other one. The medium is discharged from the rotor through one or more outlet openings in the sides or in the top of the rotor; the medium is either only raised, or is also dissipated below or above the level of the fluent medium.
