Problems solved by technology

[0006] The rose essential oil extracted by steam water distillation in the past is of poor quality, with serious loss of top fragrance and heavy color, high impurity content in the oil, and not pure aroma, etc.
[0007] 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.
[0008] 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

Abstract

The invention discloses a method of extracting rose essential oil and rose pure dew, using the distillation technique in the water vapor. The method includes the steps: (1) the roses are fed into a distillation kettle; (2) deionized water is added to the distillation kettle; (3) non-iodine salt is added to the distillation kettle; (4) the coiled pipe is opened to supply steam and heat the distillation kettle; (5) the condenser is opened to supply cooled water; the cooled oil water is mixed with steam; (6) the oil water mixture cooled by the condenser is guided into an oil water separator for the oil water separation; (7) the water layer separated by the oil water separator flows back to the distillation kettle to have repeated distillation; when the repeated distillation is finished, the repeated flow valve is closed and the collector valve is opened to collect the water layer so that the rose pure dew is obtained; (8) when the oil and water are divided into layers, the oil water separator is opened to collect the water layer so that the rose essential oil is obtained; (9) water is released and the waste slag is discharged. The method of extracting the rose essential oil and the rose pure dew has the advantages of high stability of the products, high content of the active composition, simple operation, easy mastery and low production cost.

Description

technical field [0001] The invention relates to a method for extracting rose essential oil and rose pure dew, and more particularly relates to a method for extracting rose essential oil and rose pure dew by utilizing steam water distillation technology. Background technique [0002] Rose essential oil is the king of flower oils. It is expensive and has the reputation of "liquid gold"; rose hydrosol is another product in the production process of rose essential oil. Anti-inflammatory, bactericidal and antibacterial, rose essential oil and rose hydrosol are important raw materials for the production of medicines, food, health food and advanced cosmetics. [0003] The processing technology of rose essential oil and rose pure dew has a history of hundreds of years abroad, but it is still in its infancy in our country. For a long time, due to the confidentiality of foreign technology and the domestic technology is still in the exploration stage, how to adopt a reasonable process...
