Problems solved by technology

However, due to the limitation of technology, this traditional method one-sidedly pursues the oil yield rate, which leads to serious damage to the head fragrance of rose essential oil, and damages the active ingredients CITRONELLOL citronellol and PE ALCOHOL hydrogenated ethanol in the obtained rose essential oil, making rose The essential oil has a slight burnt smell, which greatly reduces the quality of the essential oil

Embodiment 1

[0029] Embodiment 1: preparation process of the present invention

[0030] The mixture of rose flowers and water (rose flowers: water mass ratio = 1:4) is directly heated to 95°C through steam in the distillation kettle, and the steam pressure is maintained at 4-5kg / m 2 , and then stop the steam and change it to a heat coil outside the inner shell of the distillation kettle to heat the steam, and the steam pressure is maintained at 3-4kg / m 2 , reduce the temperature in the kettle and keep it at 90°C for distillation to obtain the mixture of rose oil and rose hydrosol and the distillation residue;

[0031] The mixture of rose oil and rose pure dew is separated, the rose oil is reserved, and the rose pure dew is heated by steam through a heat coil installed outside the inner shell of the distillation kettle, and the steam pressure is maintained at 3-4kg / m 2 , re-distilled at 90°C to obtain a mixture of rose oil and rose hydrosol and the residue of the re-distillation, separate ...

Embodiment 2

[0033] Embodiment 2: preparation process of the present invention

[0034] The mixture of rose flowers and water (rose flowers: water = 1:4) is directly heated to 98°C through steam in the distillation kettle, and the steam pressure is maintained at 4-5kg / m 2 , and then stop the steam and change it to a heat coil outside the inner shell of the distillation kettle to heat the steam, and the steam pressure is maintained at 3-4kg / m 2 , reducing the temperature in the kettle and maintaining the distillation at 92°C to obtain a mixture of rose oil and rose hydrosol and the distillation residue; the distillation residue extracts rose ketone to prepare rose flower body membrane;

[0035] The mixture of rose oil and rose pure dew is separated, the rose oil is reserved, and the rose pure dew is heated by steam through a heat coil installed outside the inner shell of the distillation kettle, and the steam pressure is maintained at 3-4kg / m 2 , re-distilled at 90°C to obtain a mixture of...

Embodiment 3

[0037] Embodiment 3: preparation process of the present invention

[0038] The mixture of rose flowers and water (rose flowers: water = 1:4) is directly heated to 96°C through steam in the distillation kettle, and the steam pressure is maintained at 4-5kg / m 2 , and then stop the steam and change it to a heat coil outside the inner shell of the distillation kettle to heat the steam, and the steam pressure is maintained at 3-4kg / m 2 , reducing the temperature in the kettle and maintaining the distillation at 93°C to obtain a mixture of rose oil and rose hydrosol and a distillation residue; extracting rose ketone from the distillation residue to prepare rose flower membranes;

[0039] The mixture of rose oil and rose pure dew is separated, the rose oil is reserved, and the rose pure dew is heated by steam through a heat coil installed outside the inner shell of the distillation kettle, and the steam pressure is maintained at 3-4kg / m 2 , re-distilled at 90°C to obtain a mixture o...

Abstract

The invention relates to the field of essence preparation, and discloses a preparation technique of rose essential oil. The technique comprises the following steps: directly introducing steam into a distillation kettle filled with a rose flower-water mixture to heat to 95 DEG C, stopping introducing the steam, lowering the temperature in the kettle by indirectly heating the outside of the distillation kettle inner shell, and keeping the temperature at 90 DEG C to perform distillation, thereby obtaining a rose oil-rose hydrolat mixture and a distillation residue; separating to obtain the rose oil for later use, and redistilling the rose hydrolat by indirectly heating the outside of the distillation kettle inner shell to 90 DEG C, thereby obtaining a rose oil-rose hydrolat mixture and a redistillation residue; separating the rose oil-rose hydrolat mixture to obtain rose oil and rose hydrolat; and collecting all the rose oil, and refining to obtain the rose essential oil. By regulating and optimizing the heating mode, temperature, pressure and the like during distillation in combination with the added redistillation link, the yield of the final rose essential oil is enhanced, the loss of effective components is obviously lowered, and the quality of the rose essential oil is improved.
