The high-speed shearing emulsifier means that the materials are continuously rotated and stirred in the homogenizing pot through the stirring frame in the pot, so that new interfaces are continuously generated, and the materials are sheared, compressed, and folded, so that they are stirred and mixed and flow down to the bottom of the pot. At the homogenizer, through the strong shearing, dispersion, impact, turbulence and other processes generated between the high-speed rotating rotor and the stator, the material is cut in the shearing seam, and quickly broken into particles of 200nm ~ 2μm. Material micronization, emulsification, mixing, homogenization, dispersion, etc. are completed in a short time.
