High Shear Mixing: High Shear Mixers are widely used in the cosmetic industry for preparing emulsions with viscosities under 10,000 centipoise (cP). They feature a four-blade rotor that operates at high tip speeds, creating mechanical and hydraulic shear to ensure uniform mixing .
Multi-Shaft Mixers: For products with viscosity changes exceeding 50,000 cP, Multi-Shaft Mixers are employed. These machines use multiple agitators to deliver a combination of high shear agitation and laminar bulk flow, making them ideal for highly-filled cosmetic emulsions .
Ultra-High Shear Mixers: When conventional mixers cannot achieve the desired droplet size distribution, Ultra-High Shear Mixers are used. These mixers can run at tip speeds over 11,000 ft/min, providing the necessary shear levels for stable emulsions .
Vacuum Homogenizing Mixers: These mixers are designed for the manufacturing of viscous emulsions, dispersions, and suspensions. They are particularly suitable for making large batches of cream and emulsions with a significant quantity of powders .
Advanced Homogenization: The heart of vacuum homogenizing equipment is the rotor stator homogenizer, which consists of a three-layer toothed rotor and a two-layer toothed stator. This design allows for high-speed emulsifying effects, cutting, shearing, and cracking particles into extremely small sizes .
Propeller Agitators: These agitators have blades that taper towards the shaft, maximizing axial flow. They are commonly used for blending and mixing low to medium viscosity fluids .
Turbine Agitators: Combining centrifugal and rotational motion, Turbine Agitators are versatile and suitable for various mixing applications, including high viscosity fluids .
Helical Agitators: With a twisted blade mechanism, Helical Agitators generate vigorous fluid motion, making them ideal for mixing viscous liquids .
Efficient Mixing: Agitators ensure efficient mixing, which is crucial for the uniform consistency of products like lotions and creams .
Enhanced Mass Transfer: The use of agitators can enhance mass transfer, increasing reaction rates and improving the overall efficiency of the process .
Improved Heat Transfer: Agitators can promote heat transfer to a jacket, maintaining a consistent temperature of the solution inside a vessel .
Flexible Operation: Agitators offer flexible operation, allowing for control of mixing time and quality, and accommodating a wide range of fluid viscosities .
