How to extract essential oil or essence
Key:
E.L-Essence layer
F.W- Flora water
Process Explanation
Flow diagram shows how
one can distil essence or essential oil plants’ materials. In the diagram,
water is heated to boiling point which in turn heats the plant materials to
vaporize active ingredients in them. Water vapor that carries active components
of plants’ materials is made to pass through a cooling circuit. Distilled
liquid is then steeped where it separates into two layers (fractions):
- Flora water
- Essence/essential oil
Essential oil/essence
occurs on upper layer because it is insoluble in water and less dense than
flora water. In some circumstances, a small amount of essential exists in flora
water. The extracted essence and flora water can be applied in various
industrial processes such as in perfumery, cosmetics, and production of soaps
etc.
