Oil Extraction: The History and The Chillers

July 24th, 2018 by

Have you ever wondered how plant and seed oil extraction began and when? It’s such an interesting history that goes back centuries to the days of the Egyptians who used essential oils for a variety of applications.

Found on a Young Living blog, “Essential Oils in the Ancient World: Part I” reports that it was the Egyptians who were first known to record the use and purposes of essential oils. Interesting to know that the use of oils was used in the preparation of the deceased in the practice of mummification. As this blog reports, Egypt drew researchers from neighboring countries, and the use of botanical oils began to grow.

Learn how the use of essential oils spread even further from the Egyptians to their conquerors and further on in the second part of this fascinating, blog series. The final, Young Living blog, “Essential Oils in the Ancient World: Part III” explains how the oil extraction process and the methods used have evolved to today’s machine-driven methods.

  • A boiling method was discovered that would allow for an aromatic use of the heavy oils to fill the air with beautiful smells, but topical use was not achieved by the sole practice of boiling water.
  • Eventually, finely-ground bark powder from different trees, such as cedar or sandalwood, was added to olive oil. After the mixture was “placed on a wool cloth, heated and pressed,” the extract was again added to olive oil and stored for topical or aromatic uses.
  • Another great discovery of making a more topical application was the practice of using animal fats. The fats were found to absorb the aromatic elements that lead to the process of “cold enfleurage.” This process was simply introducing fragrant plants or flower petals to animal fat and allowing the fragrances to permeate into the fat.
    • “Hot enfleurage” was also used by heating the animal fat and adding the fragrant flowers or plants until the desired aroma was achieved.
  • As more and more discoveries of extracting essentials oil continued throughout the centuries, innovations led to the methods that are more common today. “Cold pressing, soaking botanicals in alcohol, and rudimentary steam distillation” are the familiar processes we now see.

Found on wikiHow, “How to Choose the Best Process for Oil Extraction (Plant Sources)” is a simple, educational review with visual information for oil extraction. Note the 8th step regarding oil making processes. Seed oil extraction may require temperature control by means of cooling, but there are different methods for extracting oil that is either heated versus cold.

When temperatures need to be controlled in your oil extraction process is where the use of industrial chillers is added into the processing mix. The type of chiller you need depends on different factors with one being what temperature you need to achieve and the strength of your system. This is where the team at J.C. Younger can be added into the mix.
