When two liquids do not dissolve in one another they can be mixed by means of emulsification, meaning a state of dispersion in which the particles of one liquid are suspended in the other. The resultant product, known as an emulsion, is a fairly common entity. Most of our everyday use products, be it food products like egg yolk, milk, mustard, personal care products such as toothpaste, creams, gels, pharmaceutical products such as ointments, are all instances of emulsification.
Drawing upon the naturally stable and consistent physical states of the food emulsions mentioned above, industrial emulsions have been derived. These mostly belong to the pharmaceutical and cosmetic category, that also have a never-ending demand among the people of the world; there are other not so common applications of emulsification as well, such as in firefighting etc. These emulsions are manufactured by loading the mother ingredients in a vacuum emulsification mixer, and suitably agitating and blending them under different temperature presets, so as to obtain the dispersed mix. Since the whole essence of an emulsion is a series of particles suspended in a base liquid, any additional particles would change the nature of the product. Due to this, the presence of any sort of impurity is absolutely intolerable, and emulsification mixers are designed to prevent any such leakage. This includes minimizing physical movement of workmen in the production space by monitoring the process through an inspection window, and by painstakingly maintaining the environment within the laboratory. Another reason why impurities – dust or even microbes – must be avoided is that the prepared emulsion will most probably be applied on the skin, and in some cases even injected or taken orally, and thus must be pure and hygienic.
To prevent possible injuries to workmen, the steel body of the mixer is usually coated with aluminium silicate or an equivalent insulator, so as to prevent the direct manifestation of the inevitable rise in temperature, on the surface of the mixing tanks. Setting up a mixer such as this involves investing a fairly large amount of money initially, but that is more than made up for by the low operating costs achieved due to the programmable temperature and capacity presets that also help reduce the need for manual labour. This, coupled with the huge demand for the products created, a demand that will only increase with time, makes the vacuum emulsifying mixer a lucrative investment.
