Rotor-stator vacuum homogenizer
10.6 l/min | DISPERMAT® AS
VMA-GETZMANN
The homogenizer DISPERMAT® AS is a rotor-stator dispersion system. The DISPERMAT® AS rotor and stator consists of coaxially intertwined rings designed with narrow radial slots. The rotor runs at high speed across the stator. The substance to be dispersed is fed into the centre of the rotor-stator system and centrifugally accelerated by the motion of the rotor. As it passes through the rotor-stator dispersion head, the substance is dramatically accelerated both tangentially and radially. The high frequency shearing force and turbulent flow conditions ensure optimum dispersion and emulsifying action producing very fine droplets with a large effective surface area (e.g. oil/water or water/oil emulsions). Emulsification refers to the splitting and fine distribution of a liquid into a second phase in which it is not soluble. Emulsions tend to phase separate, e.g. demixing if they are not stabilised with emulsifying agents. The most important property of an emulsion is its stability.
