Agitators and Mixers

 

Our company designs and manufactures a comprehensive range of mixers and agitators to serve the chemical processing, food processing, pharmaceutical industries, cosmetic industries, and other demanding applications under brand “Dynamica”.

Dynamica employs the latest mixing simulation software for real-time optimization of mixing systems based on our customer’s process conditions. We can evaluate and improve the efficiency of our customer’s mixing process, processing time, efficiency and energy use by finite element analysis (FEA) and numerical flow calculations (computational fluid dynamics, CFD). Potential problems can be predicted in advance and avoided by analyzing the deformations, stresses and natural frequencies.

 

Applications

  1. Blending of miscible liquids.
  2. Dispersion of immiscible liquids and gases in liquids.
  3. Suspension of solid particles in slurry.
  4. Enhancement of heat exchange between the fluid and the boundary of a vessel.
  5. Enhancement of mass transfer between dispersed phases.

 

1.  Blending

  • The simplest and most common operation.
  • Mixing miscible liquids having dissimilar viscosity, density, temp, concentration.
  • Agitation purpose: to achieve homogeneity.
  • Hydrodynamics: flow-controlled, axial impeller.
  • Applications: storage, reaction, heat transfer.

2.  Dispersion

  • Mixing of immiscible phases (solid-liquid, liquid-liquid, gas-liquid, gas-solid-liquid).
  • Agitation purpose :

          - Disperse one of the phases.

          - Achieve an intimate contact between immiscible phases; one of the phases must be dispersed in the other.

  • Hydrodynamics: flow-shear controlled, radial impeller.
  • Applications: liquid-liquid extraction, absorption, hydrogenation, chlorination.
  • Dispersion: one phase is broken into small particles surrounded by the continuous liquid phase.

3.  Solid Suspension

  • The second most common operation.
  • Suspending insoluble solids in a liquid.
  • Agitation purpose: keep particles suspended in the liquid phase.
  • Hydrodynamics: flow-controlled, axial impeller.
  • Applications: crystallization, slurry feed vessels, solid, catalytic reactions, solids dissolving.

4.  Heat Transfer

  • Agitation purpose: temperature uniformity and improve vessel side heat transfer coefficient.
  • Hydrodynamics: flow controlled, axial impeller.
  • Applications: heating, cooling, reaction, distillation, crystallization.
  • Involve: heating, cooling and maintaining.
  • Sizing an agitator to achieve a specific heat transfer coefficient is impractical.

 5.  Gas-Liquid Mass Transfer

  • It is the transfer of mass from high concentration to low concentration (chemical industry application).
  • Hydrodynamics: flow controlled, axial impeller.
  • Applications: filtering, crystallization, diffusion.
