Asphalt emulsion is a combination of three basic ingredients, asphalt, water, and small amount of an emulsifying agent. In the same process, these components are introduced into a mechanism known as a colloid mill, which shears the asphalt into tiny droplets. The emulsifier, which is a surface-active agent, keeps the asphalt droplets in a ...

Mayonnaise Manufacturing Process. Commercial mayonnaise production is often a two-step process. In the first step, oil is coarsely dispersed (i.e. 20-100μm) in a pre-mix tank along with the other required ingredients. The resulting pre-mix is then transferred from the tank in a flowing stream through an emulsifying machine to finely sub-divide ...

The Process. Ingredients, formulation and product viscosity differ widely, however, a typical manufacturing process breaks down into four individual operations: Preparation of the oil phase. Flake/powder ingredients, sometimes dry blended in advance, are dispersed into mineral oil or silicone oil. Heating may be required to melt some ingredients.

In emulsion, Ostwald ripening is the process of growth of large droplets at the expenses of the smaller ones. This is a non-equilibrium process involving both thermodynamic and transport effects. Because of their smaller radii, smaller droplets experience in fact a larger capillary pressure and have therefore a larger solvability.

This process is known as inversion, and the final product is sometimes called an invert emulsion. These parameters are useful as general guidelines, but by a careful selection of emulsifier type and strict control of the particle size to keep it from getting too small, emulsions with a very high concentration of internal phase are possible.
