What types of emulsion emulsifier equipment are commonly used, and how to select them based on emulsion properties?

2026-01-10

What types of emulsion emulsifier equipment are commonly used, and how to select them based on emulsion properties?

Common types include high-shear homogenizing emulsifiers, vacuum emulsifiers, and planetary mixing emulsifiers, each suited to different emulsion characteristics:
  • High-shear homogenizing emulsifiers: Characterized by a stator-rotor structure that generates strong shear force (linear velocity 20-30m/s), suitable for emulsions requiring fine particle size (D90 < 5μm), such as cosmetic lotions and pharmaceutical emulsions. They are ideal for oil-in-water (O/W) or water-in-oil (W/O) emulsions with low to medium viscosity.
  • Vacuum emulsifiers: Integrate high-shear emulsification and vacuum deaeration, suitable for emulsions sensitive to air bubbles, such as facial creams, emulsifiable concentrates, and food sauces. The vacuum environment (vacuum degree -0.08~-0.095MPa) prevents oxidation and bubble entrapment, improving emulsion stability and appearance.
  • Planetary mixing emulsifiers: Combine planetary stirring and high-shear homogenization, with 360° scraping wall functions. They are suitable for high-viscosity emulsions (viscosity > 10,000 mPa·s), such as thick creams, pastes, and asphalt emulsions, avoiding material residue and ensuring uniform mixing.
Selection criteria: Prioritize particle size requirements for low-viscosity emulsions, vacuum function for bubble-sensitive products, and mixing efficiency for high-viscosity systems.
