Description

High-efficiency cooking tank suitable for steam extraction of essential oils

technical field

The invention relates to a high-efficiency cooking tank suitable for extracting essential oils by a water vapor method, and is suitable for the plant essential oil extraction industry.

Background technique

In the past, the essential oil extraction equipment used traditional Chinese medicine extraction tanks to put plants containing essential oils into water for cooking. When the boiling point was reached, the water vapor containing essential oils would be condensed in the condenser and then separated by the oil-water separator. And the residue after cooking is discharged through the lower slag discharge port. For softer plants, such as flower buds, this method will cause great difficulties in the extraction, collection and discharge of essential oils. Because the emulsification of the essential oil will cause losses when the aqueous solution boils, and this method consumes too much energy, there are many residues in the residue, and the discharge of the residue is easy to block, etc.
