| titleOfInvention | A kind of process method of segmented distillation and extraction of damask rose essential oil |
| abstract | The invention discloses a process method for extracting damask rose essential oil by segmented distillation, and belongs to the technical field of rose essential oil extraction technology. steam; successively use liquid nitrogen and low-temperature cooling water to condense the rose fragrance to obtain a primary rose fragrance liquid; S2 re-distill the primary rose fragrance liquid to obtain a secondary rose fragrance liquid; S3 separate the secondary rose fragrance liquid from water and oil, Obtain the crude damask rose essential oil; S4 separate the crude damask rose essential oil from water and oil to obtain clean rose damask crude oil; S5 carry out dehydration, deodorization, dewaxing and purification on the clean damask rose crude oil to obtain pure rose damask oil. Essential oil; S6 alcoholizes the pure essential oil of Rose of Damascus at low temperature to obtain the finished product of pure essential oil of Rose of Damascus; this process can greatly improve the extraction rate of essential oil. |
