Rose essential oil — often called "liquid gold" — is one of the most valuable natural extracts in the fragrance, cosmetic and food industries. Getting high yield while protecting the delicate aroma compounds requires gentle, precisely controlled extraction.
Huatai designs and builds complete rose essential oil extraction lines, applying the same continuous extraction engineering we use in edible oil plants — refined for temperature-sensitive botanicals.
Process flow
- Fresh rose petals → pre-treatment → low-temperature extraction → miscella concentration → solvent recovery → rose concrete / absolute → refining → finished rose oil
- Pre-treatment — fresh petals cleaned and conditioned to preserve volatile aroma compounds
- Low-temperature extraction — gentle solvent extraction keeps fragrance and active components intact
- Concentration — miscella evaporated under vacuum at low temperature
- Solvent recovery — closed-loop system, low solvent consumption, low residual solvent
- Refining & finishing — decolorization, filtration and dewaxing to obtain high-clarity rose oil
