Extraction of Patchouli Essential Oil by Steam Distillation Process

Distillation process of Patchouli Essential Oil is a combination of art, science and experience. With high quality stainless steel equipment, we extract essential oil from Patchouli leaves by using steam distillation method.

Main Processes

Patchouli Essential Oil Distilling EquipmentSteam Generator
A boiler is a closed vessel in which water is heated to generate steam. The steam is generated at a pressure between 80 bar to 300 bar and temperature of 450°C to 585°C with two super heaters in series. The use of such stream is very suitable for extraction of essential oil from dried patchouli leaves in the next cooker.

Dried Patchouli Leaves Cooker
High pressure hot steam from generator will flow to cooking chamber and "cook" dried patchouli leaves to extract essential oil. The steam carries patchouli essential oil will be flowing to condensation unit.

Low temperature in condensation unit will rapidly change the steam back into liquid phase. The condensed vapour consists of both water and patchouli essential oil and ready to be separated.

The condensed vapour will consist of both water and patchouli essential oil. Since water has higher specific gravity than patchouli essential oil, naturally, in a few hours, they would form two layers which could be separated using a separating funnel.

Patchouli essential oil


We highly respect the mother nature for giving us the precious patchouli essential oil. Therefore, we don't use fossil fuel such as coal and petrol to generate heat for steam generator. Instead, we use carbon neutral energy from waste biomass such as palm kernel shell, coconut shell, sawdust, etc. All spent patchouli leaves will be dried up and also would be fed into steam generator as additional fuel.
The ash residue from burning biomass is rich in calcium and natrium. Thus, it would be used in patchouli plantation to improve soil nutrients.
