The Working Process Of High Shear Lifting Emulsifying Machine Is Summarized
Sep 01, 2022
High shear lift emulsifying machine is a kind of machine that can fully refine materials. The name should be a machine that promotes the mixing of oily substances (oil phase) and aqueous substances (water phase) to form a uniform lotion. There are a variety of uniform refining machines, such as ball mill, sand (bead) mill, grinder, colloid mill, disperser, high-pressure homogenizer, etc. These machines can refine the scope of the machine and refine the uniformity. The high shear lifting emulsifying machine has the functions of refining, dispersing and homogenizing. It is mainly used for liquid-liquid emulsion homogenization, liquid-solid (powder, small particles) refining and dispersion.
The high shear lift emulsifying machine is a lift emulsifying machine that effectively, rapidly and uniformly distributes one or more phases into another continuous phase, and in general, the phases are insoluble. Due to the high tangential speed and high-frequency mechanical effect caused by the high-speed rotation of the rotor, the material is impacted by strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction and narrow gap between the stators. The combined action of tearing and turbulence makes the incompatible solid phase, liquid phase and gas phase disperse and emulsify uniformly and finely under the action of corresponding mature process and appropriate additives, and finally stabilize after high-frequency reciprocating. Operation process of high shear lifting emulsifier:
1. Under the centrifugal force of the high-speed rotating rotor, the material in the figure is sucked into the working chamber from the upper and lower feeding areas of the working head in the axial direction.
2. The weak centrifugal force destroys the material from the radial direction to the narrow gap between the rotor and the rotor. Together with the effects of centrifugation, kneading, impact, etc., the material begins to be crushed and emulsified.
3. At the outer end of the high-speed rotating rotor, a linear velocity of at least 15m / s and up to 40m / S is generated, which constitutes strong mechanical and hydraulic shear, liquid layer collision and impact tearing, which makes the material rich. Disperse, emulsify, homogenize, break and spray together through stator slots. The high shear lifting emulsifier is a high-speed rotation of the homogenizing head, which is connected with the engine to shear, crush and impact materials. This material will become more delicate and promote the integration of oil and water.
4. The material is continuously ejected from the radial direction at high speed, and the flow direction changes under the resistance of the material itself and the container wall. Together with the action of the upper axial suction and the lower axial suction occurring in the rotor region. The material undergoes several cycles and ends with a process of comminution, emulsification and homogenization.
