In the manufacture of high viscosity materials such as cosmetics, cream, ointment, shower gel, fruit juice, jam and more, have you ever come across the problems below? When you deal with the material whose particle size of the dispersed phase is large, do you find that the end product is not stable and looks matte because of the overlarge particle size? Besides, do you meet the problem of air bubbles in the end product? With the launch of High Shear Homogenizer, all these problems can be smoothly solved with the greatest ease. Through in-depth research and frequent promotion, the emulsifying machine has been applied in many different fields. So how does the high shear mixer work?
The machine can distribute one phase or more phases into another continuous phase effectively, quickly and evenly. Under normal conditions, the phases are immiscible with each other. Due to the high tangential velocity generated by the high-speed rotation of the rotor and the strong kinetic energy brought by the high frequency mechanical effect, the material is subjected to strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction, impact, tear and turbulence in the narrow gap between the stator and the rotor. Consequently, under the combined effect of relatively mature technology and proper amount of additives, the immiscible solid phase, liquid phase and gaseous phase are dispersed and emulsified evenly and finely in an instant. By means of the high frequency cycle, stable products of high quality are finally obtained.
To go deep into the working process of the High Shear Homogenizer, it can be roughly summarized in four steps. First, the rotor rotates at high speed to produce centrifugal force. Then the material is simultaneously drawn axially into the working chamber from the upper and lower feed areas of the work head. Second, the powerful centrifugal force throws the material into the narrow gap between the stator and the rotor in the radial direction. At the same time, the material is centrifugally extruded and impacted to be dispersed and emulsified preliminarily. Third, at the outer end of the high-speed rotating rotor, the line speed is at least 15m/s and can reach up to 40m/s. The strong mechanical and hydraulic shear, liquid layer friction, impact and tear are also formed to fully disperse, emulsify, homogenize and break the material. In the meantime, it will be ejected through the stator slot. Fourth, as the material is constantly thrown out in the radial direction, the flow direction changes because of the resistance from the material itself and the wall of the container. Under the action of the upper and lower axial suction force generated by the rotor region, the strong upper flipping turbulence and the lower one are also formed. After the cycle is repeated many times, the material is finally dispersed, emulsified and homogenized.
