rotorstatorsekoittimia

Rotorstatorsekoittimia, also known as rotor-stator mixers or high-shear mixers, are a type of mechanical mixing device. They are characterized by a rotor that spins at high speed within a stationary stator. This configuration creates intense shear forces, turbulence, and hydraulic forces as the material is pumped through the narrow gap between the rotor and stator. The design allows for efficient homogenization, emulsification, dispersion, and deagglomeration of various substances, particularly liquids and suspensions.

The primary function of a rotor-stator mixer is to break down particles and achieve a uniform mixture. The high rotational speed of the rotor generates significant kinetic energy. As the material passes through the rotor's teeth or slots and into the stator's corresponding openings, it is subjected to repeated mechanical stress. This process is effective for reducing particle size, creating fine dispersions, and forming stable emulsions.

These mixers find applications in a wide range of industries. In the food industry, they are used for producing sauces, dressings, and purees. The pharmaceutical sector utilizes them for drug formulation and creating stable suspensions. Cosmetic manufacturers employ rotor-stator mixers for producing lotions, creams, and makeup. They are also used in chemical processing for blending, dissolving, and producing fine chemicals, as well as in wastewater treatment for aeration and sludge homogenization. The specific design of the rotor and stator can be tailored to the viscosity of the material being processed and the desired mixing intensity.
