Emulsion is the action of high-intensity mixing, with the aim of making two immiscible liquids miscible. It can be summarized as dispersing a liquid in fine droplets (dispersed phase) in another liquid (continuous phase).  This action uses Rotor/Stator* type blades.

Emulsion is a process which, under the effect of strong agitation, makes it possible to obtain a miscible mixture from two immiscible liquids.

The principle of emulsion ensures the disintegration in fine droplets of one liquid (the dispersed phase) into another liquid (the continuous phase). An emulsifier can also be added to the mixture so that it remains stable.

 

Even if the product of an emulsion appears visually homogeneous, it remains heterogeneous from a molecular point of view, not having a static internal structure.

 

The emulsion technique is widely used in the cosmetics industry, where the mixture of liquids is used in the majority of skin care products such as creams, milks, gels, etc. The emulsion technique is also used in the cosmetics industry.
In this sector (but also in the pharmaceutical and food-processing industries), many emulsions also contain emulsifiers (or emulsifiers) or surfactants which will enable them to reinforce their stability and homogeneity by forming a "film" around the droplets in the continuous phase.

 

The emulsion process is generally carried out in tanks equipped with magnetic stirrers. At Agitec, it is the mobile Rotor/Stator that is dedicated to this mixing technique. It consists of a turbine with 4 straight blades for the rotor and a cylinder with vertical openings for the stator.
This mobile creates a vortex by depression, with a horizontal centrifugal radial flow, and offers a very important shearing effect at maximum speed.

 

This type of rotor can also be used for all applications involving two or more immiscible liquids.
