Simply repeating the agitator rotation rarely preserves process behavior at a larger scale. Impeller diameter, tank geometry, viscosity, and flow regime alter mixing efficiency.
Essential variables
Consistent scale-up combines product data and process criteria.
- Power per unit volume
- Tip speed and shear stress
- Homogenization time
- Heat exchange and solid incorporation
Test before manufacturing
Simulations, tests, and a clear definition of the expected result reduce uncertainties. The final solution can then combine an agitator, baffles, homogenizer, and speed control according to the application.
