Dispersion Turbine Mixing Element
Core Function
High-speed dispersers excel at three critical tasks:
- Fracturing powder agglomerates into fine particles
- Creating uniform powder distribution throughout liquid mediums
- Facilitating complete dissolution of soluble materials
As the disc spins, it generates powerful suction forces, pulling materials toward the mixing zone. The rotation creates dual vortices—above and below the disc—where intense energy transfer occurs upon material contact with the blade.
This energy transfer creates dramatic velocity differentials throughout the mixture, generating shear forces that tear material layers apart.
Performance Boundaries
A disperser’s effectiveness depends on material properties:
- Excessive viscosity prevents material circulation between blade and tank wall
- Insufficient viscosity fails to generate adequate layer separation
- Adhesive materials disrupt proper flow patterns
Optimal performance creates a distinctive toroidal (doughnut-shaped) flow pattern with the blade positioned at the center void.
Engineering Solutions
- Additional agitation mechanisms can improve material delivery to the disperser blade
- Multi-shaft systems combine slow-moving wall scrapers for bulk movement with high-speed disperser elements for shear generation
Tank Design Essentials
Optimal manufacturing vessels feature:
- Height slightly exceeding width
- Curved or bowl-shaped bottoms preventing material accumulation
- Centered drainage points for complete evacuation
Formulation Strategy
- Material addition sequence dramatically impacts results
- Best practice: Add approximately half of total powders rapidly into the liquid vehicle
- Introduce remaining powders with progressively decreasing speed
- Adjust blade speed from 50% of final tip speed initially, increasing to maximum as batch thickens

Fermentation & Bioreactor Mixing Process
Bioreactors and Fermenters are culture systems to produce cells or organisms. They are used in various applications, including basic research and development, and the manufacturing of biopharmaceuticals, food and food additives, chemicals, and other products. A broad range of cell types and organisms can be cultivated in bioreactors and Fermenters, including cells (like mammalian cell lines, insect cells, and stem cells), microorganisms (like bacteria, yeasts, and fungi), as well as plant cells and algae. The words “Bioreactor” and “Fermenter” are basically the same thing.
