| titleOfInvention | A kind of extraction method of rose essential oil and rose hydrosol |
| abstract | The invention discloses a method for extracting rose essential oil and rose hydrosol, comprising the following steps: (1) at 5-7 in the morning, when the temperature is 5-23° C., and the relative air humidity is 55-70%, picking flowers to bloom until Half-cup-shaped roses with yellow stamens, select plump, unsqueezed rose petals; (2) Put rose petals and water in a still, and first use indirect steam to heat the temperature in the still to 70～80℃, direct steam to be heated to boiling, the internal pressure of the distillation device is 0.07～0.09MPa; (3) The mixture of rose oil and rose hydrosol and the distillation residue produced by distillation are passed into the condenser and the oil-water separator Condensation and oil-water separation are carried out inside to obtain rose essential oil and rose hydrosol; (4) the obtained rose hydrosol is passed into the re-sliding column, heated and re-slid for 10 to 20 minutes under the action of the rising steam of the still, and then subjected to condensation, Oil and water are separated to obtain refined rose hydrosol. The rose essential oil obtained by the method of the invention has high oil yield, high purity of rose hydrosol and long storage time. |
