Problems solved by technology

In the organic solvent extraction method, because the extraction method needs to use a large amount of organic solvents, the consumption of organic solvents is large, and the production cost is high. At the same time, the obtained products have more or less solvent residues, which affect the quality of the products.
Carbon dioxide supercritical extraction method extracts rose essential oil. Although carbon dioxide supercritical extraction method is the most advanced technology for extracting rose essential oil at home and abroad, it has a slight advantage in the yield of rose essential oil, but it is not very pure in terms of aroma, and carbon dioxide supercritical extraction method is the most advanced technology for extracting rose essential oil. The extraction process of the critical extraction method is complicated, the requirements for production equipment are high, and the production cost is high

Embodiment 1

[0018] A method for extracting and purifying rose essential oil, which is processed by steam distillation combined with frequency conversion re-distillation technology, specifically comprising the following steps:

[0019] ⑴Feeding: Open the water injection valve on the top of the still, and inject 150-200kg of clean water into the still. The roses that are processed, the pure fresh flowers weight before pickling is used as the criterion when the said roses that are pickled are fed, and the feeding port is covered;

[0020] (2) Extract rose oil: Control the air pressure of the main gas supply pipeline of the boiler between 0.3-0.4MPa, first half-open the cooling water valve, then open the steam inlet valve of the distillation kettle to add steam, control the steam pressure at 0.05-0.08MPa, and start distillation For operation, open the water outlet valve between the oil-water separator and the double distillation column, close the valve between the oil-water separator and the ...

Embodiment 2

[0024] ⑴Feeding: Open the water injection valve on the top of the still, and inject 150-200kg of clean water into the still. The roses that are processed, the pure fresh flowers weight before pickling is used as the criterion when the said roses that are pickled are fed, and the feeding port is covered;

[0025] (2) Extract rose oil: Control the air pressure of the main gas supply pipeline of the boiler between 0.3-0.4MPa, first half-open the cooling water valve, then open the steam inlet valve of the distillation kettle to add steam, control the steam pressure at 0.05-0.08MPa, and start distillation For operation, open the water outlet valve between the oil-water separator and the double distillation column, close the valve between the oil-water separator and the rose hydrosol storage tank, and start timing when condensed water flows out from the water outlet of the condenser, and continue to extract for 4.5 hours During this period, the temperature of the condensate outlet o...

Embodiment 3

[0030] A method for extracting and purifying rose essential oil, which is processed by steam distillation combined with frequency conversion re-distillation technology, specifically comprising the following steps:

[0031] ⑴Feeding: Open the water injection valve on the top of the still, and inject 150-200kg of clean water into the still. The roses that are processed, the pure fresh flowers weight before pickling is used as the criterion when the said roses that are pickled are fed, and the feeding port is covered;

Abstract

The invention discloses a rose essential oil extracting and purifying method, and belongs to the technical field of extraction and separation of natural products. According to the rose essential oil extracting and purifying method disclosed by the invention, a steam distillation method is adopted, and a frequency conversion compound distillation technique is combined, so that rose flowers are processed. The rose essential oil extracting and purifying method comprises the following steps of (1) feeding materials; (2) extracting rose oil; (3) refining the extracted rose oil; and (4) removing residues, and cleaning a distillation still. When filtration treatment is performed on the rose essential oil refined in the step (3) once again through a biomembrane filter or a ceramic filter, oral administration grade rose essential oil can also be obtained. According to the rose essential oil extracting and purifying method disclosed by the invention, the distillation time and the distillation temperature are strictly controlled, so that the quality and the yield of the rose essential oil products are substantially increased, besides, working procedures are easy to master, the production cost is low, and the rose essential oil extracting and purifying method is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction and separation, relates to plant essential oil processing technology, in particular to a rose essential oil extraction and purification method. Background technique [0002] Rose belongs to the Rosaceae plant, which is an economic flower integrating ornamental, edible, and medicinal uses, and is also a precious spice plant. Rose essential oil, a high-grade spice extracted from roses, is very expensive in the international market. [0003] Rose essential oil has many special effects. In addition to being used as a high-grade cosmetic raw material, it also has the effect of treating various diseases. Rose essential oil can stimulate and coordinate the human immune and nervous system, and at the same time help to improve the secretion of endocrine glands, remove organ sclerosis, repair cells, etc., and also improve the function of the digestive tract. [0004] The processing of r...
