Vacuum emulsifier mixer is a coaxial mixer of triple type, which is used for stable homogenizing and emulsifying with refined granules. The quality of emulsification is depending on the dispersion of granules at the stage of preparation. The smaller the granules are, the weaker the surface aggregation will be, so the damage chance of the emulsifying will be less. The homogenizer will achieve high-quality emulsifying mixing effect depending on the hybrid actions of reversing impellers under the vacuum condition of treatment. This machine has a good performance on quality guarantee of finished products.
