Emulsification by mechanical agitation
Emulsification processes – Techniques and equipment

Principle and mechanisms

The aim of these devices is to create the right shear to encourage droplet breakup; in this sense, radial agitator mobiles are well suited. But the role of the agitator is not limited to droplet formation in the agitated tank: it must also ensure good recirculation, in order to provide a fairly narrow size distribution, because as the droplets move away from the agitator, and therefore from the shear zone, they tend to coalesce. A breakage-coalescence...
