In the emulsification system, there are common water-in-oil emulsification and oil-in-water emulsification systems. Water-in-oil systems can generally be prepared by emulsifiers and other equipment including cold blending and hot blending, one-pot, intermittent, and continuous processes. Cold matching The cold blending efficiency is high, the energy consumption is small, the continuous production cost is low, and the time-consuming is low, suitable for low or medium viscosity. If the oil phase is heated and then cooled, if it is opaque or turbid, it is heated and then cooled. After being homogenized by an emulsifier at room temperature for a period of time, pump into the water phase. If the oil phase is heated and dissolved in the oil phase tank of the emulsifier and remains clear and clear after cooling to room temperature, the water phase can be directly pumped into the main emulsification pot for emulsification and homogenization and cooling at the same time after ...
