Description

technical field

[0001] The invention belongs to the technical field of tobacco chemistry, and in particular relates to a device and method for extracting tobacco essential oil by superheated steam distillation. Background technique

[0002] There are many methods to extract the active ingredients of the volatile components of plants, such as solvent extraction, supercritical fluid extraction, subcritical extraction, steam distillation and so on. Among these methods, supercritical and subcritical extraction methods can be carried out at low temperature without destroying volatile components. However, the equipment of this method is complex and the extraction cost is relatively high. Among many methods, steam distillation is simple, effective, low cost and safe to operate. It is the most commonly used method for plant essential oil extraction.

[0003] However, the steam distillation method also has defects in some aspects: on the one hand, the water vapor will be partially ...
