The essential oil vacuum distillation method for extracting essential oils is the most commonly used method for extracting aromatic plant essential oils, and 90% of aromatic plant essential oils are obtained by distillation. 

This essential oil vacuum distillation method involves placing plant parts (flowers, leaves, etc.) containing aromatic substances into a large stainless steel distillation vessel (still) and heating or introducing steam at the bottom of the vessel. When the hot steam is filled in the container, the fragrant essential oil components in the plant will evaporate with the water vapor, and the water vapor will pass through the upper condenser tube and finally be introduced into the condenser.

Oil lighter than water will float on the surface, oil heavier than water will sink to the bottom, and the remaining water is hydrosol. Then use an oil-water separator to further separate the essential oil and hydrosol for storage.
