The powerful motor of the laboratory homogenizer rotates at high speed to generate vacuum condition between the rotor and stator, so materials are sucked into the chamber from the top of the stator& rotor and also from the bottom. Rotor driven by the strong kinetic energy creates high linear speed, which puts the materials under comprehensive action of strong crushing, tearing, centrifugal extrusion, hydraulic friction etc between the precision-engineered gap of the stator and rotor. After processed, the materials are flying out and generate strong turbulence under the action of forces from different direction. Stable emulsion is obtained after repeated disaggregating, dispersing, homogenizing, shearing for a certain period with help of mature production technology and certain quantity emulsifier.
