Introduction of Laboratory High Shear Mixer
The laboratory high shear mixer is a kind of equipment designed for laboratory research and development, aimed at emulsifying liquid mixtures into stable emulsions using high shear forces. It consists of a rotating rotor and a fixed stator, designed with blades on both components that match each other. When the rotor spins at high speed, the intense turbulence and shear forces created between the blades result in strong mechanical action on the liquid mixture, leading to the mixing and emulsification processes.
The primary function of the laboratory high shear mixer is to combine and emulsify two or more immiscible liquids to form small and stable emulsions. These liquids can be combinations of oil-water emulsions, liquid-liquid emulsions, or liquid-solid emulsions. By utilizing high-speed rotation and cutting action, the laboratory high shear mixer efficiently disperses and evenly distributes droplets, resulting in uniform emulsions.
Principle of Laboratory High Shear Mixer
The laboratory high shear mixer combines liquids together by utilizing high-speed rotation and shear forces. Its working principle involves the following key steps:
Rotor and stator configuration
The laboratory high shear mixer typically consists of a rotating rotor and a fixed stator. The rotor is equipped with blades, while corresponding blades are present on the stator.
Shear and turbulence action
When the rotor spins at high speed, it creates intense turbulence and shear forces between the blades. These forces subject the liquid mixture to vigorous mechanical action between the rotor and the stator.
Liquid mixing
The shear and turbulence action results in strong interactions among the components of the liquid mixture. This leads to the dispersion of immiscible liquids and the formation of small liquid droplets. Meanwhile, the soluble components in the liquid also mix more effectively.
Micro-mixing
Under the influence of high shear forces, the liquid droplets continue to be cut and dispersed, ultimately forming uniformly dispersed micro-droplets. This ensures a more even distribution of the mixture’s components throughout the system.
The working principle of the laboratory high shear mixer relies on the shear forces and turbulence generated by high-speed rotation. These actions allow for effective mixing and dispersion of the liquid mixture, achieving a homogeneous mixing effect.
