Liquid Mixing Process

Liquid mixing is a critical component in pharmaceutical, chemical, or other related Industries. Improper or inadequate mixing will compromise the final quality of the product, resulting in losses.

There are many aspects to liquid mixing. It will typically occur in a mechanical agitation system. It is a complex, multifaceted process, which requires a proper understanding of:-

  • Flow aspects
  • The mechanical and power requirements of the equipment
  • The agitation speed
  • The time you require for proper mixing and circulation
  • Power consumption
  • Distribution of the drop size
  • Coalescence and break-up
  • Phase inversion
  • Interfacial areas, among others.

Complexity Levels

At the basic level, the liquid mixing process can be very straightforward. This is true with miscible or liquids that share similarities. Even in your everyday life, you deal with miscible liquids at least once a day. When you put some milk in your coffee or tea, the mixing is straight forward. If you want some honey, the process of blending it in will require equipment such as a spoon.

However, if you have to deal with immiscible liquids, such as oil and water, there can be some challenges. The complications increase when there are solids. For the latter, proper mixing will require the meeting of certain standards. Such include the power of the blending unit and the time you allocate.

If there are any additives, the engineer must watch out for solidification that could cause serious problems in the different equipment.

Liquid Mixing Process

The type of equipment the engineers use in the liquid mixing process will depend on the nature of the liquids.

Liquid engulfment combine high-flow and low shear mixers
Multiphase mixing is more multifaceted. It uses low-flow, high shear mixers in transitional, laminar, or turbulent flow regimes. The final result is the formation of droplets arising from one Liquid.
Transitional or turbulent mixing occurs in impeller or turbines.
Laminar mixing happens in anchor mixers or helical ribbons.
