Traditionally, ‘Micro mixing’ is associated with Mixing at levels below submicronic, but higher than molecular size. Single molecule is generally a few Angstrom to several (multiple of 10) Angstrom Macromolecules, such as polymer, protein, cellulose etc are larger.
Micro mixing is achieved by high level of Turbulence, or, by devices such as Static Mixers and Eductors. Micro mixing is also used as a concept to mathematically solve complex Turbulent Mixing process. For any chemical reaction, molecules have to meet. The final distances are covered by molecule diffusion process. But micro mixing can bring the molecules closer so that the reaction time can be minimized.Micro mixing is useful in several processes other than reactions, where the ‘Scale of Scrutiny’ is small, for example :
- Mixing Color in Soaps and other Toiletries
- Homogenizing Milk.
- Mixing Color in Plastics.
Recently, ‘Micro mixing’ – leads to Micro Mixer, that is when the Mixer, the equipment, itself takes Micronic Level. Generally these Line Mixers operate at low Reynolds Number. By creating circular motion there is an attempt here to create vortices inside the flow to improve mixing.
