Method for extracting essential oil from damask roses

The invention relates to a method for extracting essential oil from damask roses and relates to the technical field of essential oil preparation. The method comprises the steps of selecting internal petals, immediately immersing in clear water and slowly stirring and washing; putting the washed damask rose petals into a freezer, the temperature of which is adjusted in advance, rapidly freezing for4-6 hours, taking out and immediately putting in a preheated water bath distiller; continuing heating the preheated water bath distiller in which the frozen damask rose petals are placed to 100 DEG Cunder normal pressure; and feeding mixed liquid condensed and discharged by a water cooler into an oil-water separator, separating the essential oil from the water and injecting the essential oil into an essential oil storing tank. The method has the beneficial effects that the refining speed is increased; the defects caused by the short cycle and the perishability of the damask roses are solved;the quality of the essenti
