When the system is pressurized, essential oils can be distilled at temperatures well below their normal boiling point; thus protecting the integrity of their delicate and complex chemical profiles. When using steam distillation, it is vital to pay careful attention to the heat source. The ...
Adopting stainless steel material, the product extracts pure dew and essential oil by the method of steam distillation. It can extract essential oil rapidly in 10 minutes, whose oil extraction rate is greater than 99%. Model Voltage/V Maximum Power/W P...
A new process design and operation for steam distillation of essential oils that increases oil yield and reduces loss of polar compounds in wastewater was developed. A packed bed of the raw materials, as opposed to hydrodistillation, was used. The packed bed sits above the steam source and ...

This is the most common way to extract essential oils.The part of the plant being used, is packed into a chamber above hot water. The steam produced travels through a condenser, where it is cooled into a liquid. Then it collects in a large container as essential oil on the top, and ...
The results were similar to those from simultaneous distillation extraction. The developed method was simple, fast, effective, sensitive, and provided an overall profile of the volatile components in jujube extract. Thus, this method can be used to determine the volatile components of extracts. ...
