rotorstatorihomogenisaatoreid

Rotorstatorihomogenisaatoreid are high-shear fluid-processing devices used to reduce particle size and create stable emulsions by forcing liquid through the small annular gap between a rapidly rotating rotor and a stationary stator. The rotor typically carries blades or lobes and drives liquid toward the stator, which has holes, slots, or orifices. The resulting shear, turbulence, and cavitation break up droplets and create uniform dispersions.

Design and configurations vary from inline, single-pass units to multi-stage recirculating systems, from laboratory to industrial scale. Materials of construction commonly include stainless steel (often 304 or 316), with sanitary designs for food and pharma markets. Stator patterns vary in hole size, thickness, and geometry, affecting shear and pressure.

Applications span multiple industries, including food and beverages (mayonnaises, dressings, dairy emulsions), cosmetics (creams, lotions), pharmaceuticals (suspensions, ointments), personal care, and chemicals or polymers (stabilized emulsions, nanodispersions).

Performance and operating considerations center on rotor speed (rpm), gap clearance, throughput, viscosity, and temperature. Higher speed and smaller gap increase shear but raise energy consumption and heat generation. Pre-milling or pre-homogenization can improve results. Inline units support continuous processing, while batch systems allow more controlled mixing. Cleaning and validation requirements are important; many designs emphasize cleanability and sterilizability where applicable.

Maintenance focuses on wear parts such as the stator ring and rotor seals, regular inspection, and timely replacement. Proper cleaning protocols and lubrication of bearings are essential to extend service life and ensure process reliability.
