The Most Versatile Mixing System Available Today

With the unique patented dynamic stator system, it is now possible to mix and homogenize in one unit operation, going from low shear to high shear with a single input.

Because the powder introduction point is below the liquid surface in the mixing vessel, instant wetting of the ingredients is achieved for even the most difficult applications.

Typical applications include:

  • Pharmaceutical coating solutions
  • Infant and nutritional formulations
  • Semi-solids, creams and lotions

As a result, very short mixing times are possible with a high degree of process flexibility.

Batch sizes from 50 ltrs. (13 Gal.) to 15,000 ltrs. (3,900 Gal.)

Rotor sizes from Ø 120 to Ø 600 mm. Power consumption from 5 to 630 kW.

Frequency control of mixing speed.

Options:

  • Cooling / Heating
  • Different stators
  • Inducer or knife
  • Scraper agitator
  • Direct steam injection
  • Condition monitoring system
  1. The product is sucked into the mixing vessel under vacuum at a point adjacent to the turbo wheel. The powerful forces of the turbo wheel secure instant wetting of the product.
  2. The speed across the tank wall generated by the turbo wheel gives optimum heat transfer when using the jacket for heating, especially when the stator is lifted due to higher flow.
  3. High shear mode: the stator is lowered and all product flow is forced through the stator holes to break down particles and give a homogenous mix/product. The shear level is determined by the hole size in the stator and the speed of the turbo wheel is regulated by an inverter drive.
  4. Low shear/blending mode: the stator is raised and the product flow is fast but gentle. This mode allows the addition of particulates/ solids to be blended into the product homogeneously with little or no damage or chopped using one of our special knife attachments.
