This ancient method of extraction can be dated back around 5,000 years with the discovery of earthenware stills. The distillation process hs remained relatively the same in the last 1,000 years. Today most stills are made of stainless steel or copper.
In steam distillation, steam from a separate boiler is injected into the distillation vessel. The essential oil is extracted at a much faster rate than the water distillation.
The raw material vessel
The boiler tanks functions as a ignition process for the essential oil extractor in this method. The raw material is put in the burner, the extraction process starts as the material gets heated and converted into steam. The steam is carefully maintained for the plants and the raw material to Leave the essential oil.
Condensation, distillation, separation
The steam which gets extracted contains the essential oil which is then cooled in the condensation process in this cylindrical tunnel,which forms a liquid from which the essential oil and water is then separated. The essential oil is then collected in the separate tank shown in the image and ready to be packed and distributed globally.
