The use and characteristics of high shear emulsifier
Date: 2020-10-30Read: 8
A high shear dispersing emulsifier is a process of quickly and uniformly transferring one or more phases (liquid, solid, gas) into another immiscible continuous phase. Under normal circumstances, each phase is immiscible with each other. When external energy is input, the two materials recombine into a homogeneous phase. Due to the high tangent speed generated by the high-speed rotation of the rotor and the strong kinetic energy brought by the high-frequency mechanical effect, the materials are subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tear and turbulence in the narrow gap between the stator and rotor, forming suspension, lotion and foam. Thus, the immiscible solid, liquid, and gas phases can be uniformly and finely dispersed and emulsified in an instant under the combined action of corresponding mature processes and appropriate additives. After high-frequency cycling, stable high-quality products are finally obtained.
The pipeline type high shear emulsifier consists of a rotor and a stator. Under the high-speed drive of the motor, the material moves at high speed in the narrow gap between the rotor and the stator, forming turbulent flow. The material is subjected to stronger hydraulic shear, centrifugal extrusion, high-speed cutting, impact and grinding, and other comprehensive effects, thereby achieving the effect of dispersed emulsification and crushing. The particle size distribution range, homogenization and refinement effects, and yield are determined by the physical properties of the processed material, the number of working chambers, and the duration of material residence in the working chamber.
Characteristics of Emulsifier
1. Precise fit of rotor and stator, claw structure of working head (rotor and stator forging manufacturing);
2. Bi directional suction, capable of ultrafine dispersion and emulsification of materials, with high shear efficiency;
3. Emulsifier eliminates quality differences in production between batches
4. Stable operation, low noise, easy cleaning, flexible maneuverability, and continuous use;
5. The working temperature is less than 180 degrees Celsius;
6. Explosion proof design, safe and reliable;
7. High shear emulsion pump has a large processing capacity, suitable for industrial online continuous production, and has a narrow particle size distribution range and high uniformity
8. Save time and energy
9. The precision cast integral frame and each rotor tested for precision dynamic balance ensure low noise and smooth operation of the entire machine
