What are the main types of mixing emulsifiers?

2025-12-01

What are the main types of mixing emulsifiers?

Mixing emulsifiers are classified based on their structure, working principle, and application scenarios. Common types include:
  • Rotor-Stator Emulsifiers: The most widely used type, consisting of a rotating rotor and a fixed stator with precision slots. They generate high shear force and are suitable for batch or continuous production (e.g., inline rotor-stator emulsifiers for continuous processing).
  • High-Pressure Homogenizers: Force materials through a narrow gap at extremely high pressure (typically 100–1500 bar), using shear, impact, and cavitation effects to achieve emulsification. Ideal for producing fine emulsions (nanoscale) in industries like pharmaceuticals and food.
  • Colloid Mills: Utilize a rotating cone or disk and a fixed cone/disk with a small gap. Materials are crushed and sheared as they pass through the gap, suitable for high-viscosity materials (e.g., adhesives, cosmetics).
  • Ultrasonic Emulsifiers: Use high-frequency ultrasonic waves to create cavitation in liquids, breaking down droplets. Suitable for lab-scale or small-batch production of fine emulsions.
