High shear emulsifier is designed for mass production, using claw bite, double and suction structure, to avoid the dead space and vortex phenomenon caused by the upper part of the material is difficult to inhale. The shear force of the equipment is stronger, thus the production efficiency and dispersing emulsification quality are improved.

When the external energy input, the two materials reorganize into a homogeneous phase. Due to the high tangential speed generated by high-speed rotor rotation and high-frequency mechanical effects brought about by the strong kinetic energy, so that the material in the stator and rotor narrow gap by a strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction and turbulence and other integrated effects, the formation of suspensions (solids/liquids), emulsions and foams. Thus the immiscible solid phase, liquid phase, gas phase in the corresponding mature technology and the appropriate amount of additives under the joint action, instant uniform fine dispersion emulsification, after high-frequency cycle, to obtain stable high-quality products.

The following is an introduction to the working process of high shear emulsifier:

1, in the high-speed rotation of the rotor generated by the centrifugal force, the material from the working head of the upper feed area at the same time from the axial suction into the working chamber.

2, strong centrifugal force will be thrown from the radial direction of the material into the narrow precision gap between the fixed and rotor. At the same time by centrifugal extrusion, impact and other forces to make the material initially dispersed emulsification.

3, in the high-speed rotation of the outer end of the rotor to produce at least 15m / s more than the linear velocity, up to 40m / s, and the formation of strong mechanical and hydraulic shear, liquid layer friction, so that the material is fully dispersed, emulsification, homogenization, crushing, and at the same time, through the radial jet from the out. After a treatment or cycle of treatment to complete the dispersion, emulsification, homogenization process.

4, or in the second group of rotor centrifugal force, into the second stator, rotor work area: once again through the stator, rotor multi-layer, intensive, uniform shear effect, from the radial jet out, in the third group of rotor centrifugal force, into the second group of stator, rotor work area, to complete the dispersing, emulsifying, homogenizing and other processes. After three groups of stator and rotor processing in turn, the material in a short period of time to get uniform processing, and finally complete the dispersion, emulsification, homogenization process.
