Commingling, Emulsion

Blender, and agitator are equipment for cosmetic and pharmaceutical production as well as in chemical and agribusiness.

Mixers, emulsifiers or stirrers are tools used in the cosmetic industry (creams, skincare, make-up, toothpaste, shampoo, lotions), the pharmaceutical industry (syrups and ointments), the food industry (dairy products, sauces, jams, powders), the chemical industry (paints, glues).
They allow to mix liquid/liquid, liquid/gas, liquid/solid or solid/solid products.
The agitator part plunges into a tank which contains the material to be mixed. This tank can be heated and equipped with a cover for the introduction of gas or for vacuum work.
In the design of viscous products, the issues are the possible oxidation of the material by air bubbles trapped in the cream or paste. With the emulsifying mixer, working under vacuum allows to control and limit the trapped air bubbles. The mixing process also maintains the emulsion, i.e. the oily particles in suspension in another liquid for a homogeneous texture.
The agitation system can have several forms depending on the use. We speak of mixers with blades or ribbons. The paddles are more powerful than the ribbons, they allow to go faster for the homogenization of the mixtures. Paddle mixers are less delicate than ribbon mixers and can damage the most fragile materials. Paddle mixers can be central, side, bottom or all three.
For materials in powder form, conical or biconical mixers are available.

The choice of the mixer depends on the physical behaviour, temperature, density, viscosity, concentration, particle size and sedimentation rate.
Thus, a mixing tank is often dedicated to a single use (cosmetic, food, chemical, etc.).

Once the products are mixed, emulsified and homogenized, the next step is the packaging of the products.
