Vacuum Homogenizing Emulsifier means when the materials are under the vacuum condition, it makes use of the high shear emulsifier to distribute one or several to another continuous phase rapidly and evenly. The materials will be processed in the narrow space between the stator and rotor by strong energy of motion produced by the machine effect. By the operation of hydraulic shearing, centrifugal extruding, impacting, breaking and turbulence for over 199 thousand times per minute, the materials will be dispersed and emulsified instantly and evenly. After reciprocating circulation at high frequency, the fine finished products of stable and high quality without bubbles will be achieved. The product of vacuum emulsifying mixer machine mainly applied in such industries as daily chemical care products, biopharmaceutical industry, food industry, paint and ink, nanometer materials, petrochemical industry, printing and dyeing auxiliaries, pulp & paper, pesticide, fertilizer, plastic & rubber, electronic and electronics, fine chemical industry, etc. The emulsifying effect is more prominent for materials of high base viscosity and high solid content.
