In the manufacturing technology of high viscosity emulsifying materials especially cream and ointment etc. Materials, the common problem is that during the blending, the products are mixed with air, which will cause product aerification, bacteria pollution and oxidation, leading to bad quality of finished products. For this, there with adopts vacuum emulsifier to prevent the materials from being mixed with unclean bubbles through the method of vacuum exhaustion in the vessel during the blending and emulsifying, so that high quality products with luster, fine quality and good ductility can be manufactured.
