Operation mode and principle of high shear emulsifier

The high-shear emulsifier is a machine that can fully refine the material uniformly. The source of its name should be a machine that can promote the mixing of oily substances (oil phase) and aqueous substances (water phase) to form a uniform emulsion. And there are many kinds of machines for uniform refinement, such as ball mills, sand mills (bead mills), pulverizers, colloid mills, dispersers, high-pressure homogenizers, etc. These machines can be used to refine materials. The homogenization ability varies. The high-shear emulsifier has the functions of refinement, dispersion and homogenization. It is mainly used for liquid-liquid emulsification homogenization, liquid-solid (powder, small particles) fine dispersion.

In the high-shear emulsifier, the strong kinetic energy brought by the high tangential speed and high-frequency mechanical effect generated by the high-speed rotation of the rotor causes the material to be subjected to strong mechanical and hydraulic shearing and centrifugal extrusion in the narrow gap between the stator and the rotor. , Liquid layer friction, impact tearing and turbulence, etc., so that the immiscible solid phase, liquid phase, and gas phase are dispersed and emulsified instantly and evenly and finely under the combined action of the corresponding mature technology and appropriate amount of additives. The cycle goes back and forth, and finally a stable and high-quality product is obtained.
