Problems solved by technology

[0016] The deficiencies in the production process of extracting jasmine extract and jasmine essential oil in the above-mentioned documents are that the residual solvent recovery device in the flower dregs uses water vapor to directly take away the solvent for recovery, which is easy to cause the solvent to carry water. On the other hand, the long-term high temperature High pressure will oxidize and denature the high content of protein in the flower dregs, resulting in a peculiar smell. It is difficult to remove the polluting solvent, which will affect the product quality and aroma of jasmine extract during recycling.

Embodiment 1

[0066] Embodiment 1: countercurrent swimming dipping continuous extracting paste method

[0067]The large, white jasmine flower buds picked by the purchased flower farmers are scattered indoors. When the buds bloom and release their fragrance, the belt conveyor continuously sends the flowers into a horizontal sealed stainless steel cylinder with screw propellers and different pitches. In the main extraction machine composed of paddle leaves, the solvent is pumped at the same time, so that the solvent moistens the jasmine flowers. Adjust the stepless speed regulating motor to make the main shaft drive the propeller to run slowly, so that the raw material and solvent move in the countercurrent direction. The ratio of fresh flowers and solvent in the main machine is 1:5, and the ratio of pumping of circulating solvent and adding of fresh flowers is kept, so that the machine The inner flowers can be completely in the state of swimming and immersion. The flowers move up slowly whi...

Embodiment 2

[0069] Embodiment 2: single-tank scraper type soaking machine extracts and prepares extract method

[0070] After the jasmine flower buds are bought back from the market, cool them in the empty room of the workshop to prevent overheating and deterioration. When the buds bloom and release their fragrance, put them into a 1.5m scraper type flower extraction machine with a loading capacity of 400-500 kg / machine, with raw materials ( Fresh flowers): Solvent (solvent) = 1:3.5-4 Add solvent (generally 2 / 3 of the capacity of the solvent liquid device is observed from the sight glass), start the motor to drive the scraper to rotate slowly, and the solvent will be removed after about 30 minutes. The outflow from the bottom of the machine is injected into the top of the pumping machine through the sealed pipe, and the cycle is repeated. The flowers are rotated by the scraper to roll slowly in the machine. After 1.5 hours of extraction time, the tank can be put into the tank, and all th...

Embodiment 3

[0075] Transform the 1.5-meter-diameter scraper-type flower extraction machine (steam spray heat structure) into a heat-insulating transfer type (heat-conducting oil heat exchange structure), and conduct heat to the inside of the flower extraction machine through heating oil,

[0076] Buy jasmine flower buds from the market and let them cool in the empty room of the workshop. When the buds bloom and release fragrance at 9-10 pm, put them into a 1.5m scraper type flower extraction machine with an input of 400--500 kg / machine. Raw materials (flowers): No. 70 solvent oil = 1:3.5-4 ratio to add solvent, the solvent volume is 2 / 3 of the capacity of the extractor, start the motor to drive the scraper to rotate slowly, and the solvent will be removed from the bottom of the extractor after about 30 minutes The outflow is injected from the top of the pumping machine through the sealer, and the cycle is repeated. After 1.5 hours of extraction time, the tank can be put into the tank, and...

Abstract

The jasmine oil extracting process includes circular countercurrent leaching of jasmine in leaching machine for 1-3 hr to obtain leached liquid; decompression concentrating the leached liquid to obtain ropy extractum while recovering solvent; extracting the ropy extractum with supercritical CO2 fluid to separate coarse jasmine oil; and rectifying to eliminate water, residual solvent and impurity and obtain refined jasmine oil. The said process has refined jasmine oil yield of 48-55 %.

Description

technical field [0001] The invention relates to a method for extracting active ingredients from fresh flowers, in particular to a method for extracting jasmine aromatic oil from jasmine flowers. technical background [0002] Jasmine flowers are widely planted as an ornamental and characteristic industrial plant and as a raw material for extracting spices due to their rich natural aromatic components. After chemical analysis, the main components of the fragrance of jasmine are: benzyl acetate, α-linalool, leaf alcohol, methyl jasmonate, linaloyl acetate, ethyl benzoate, methyl aminobenzoate, jasmine lactone, Composed of a mixture of dozens of organic compounds such as cis-jasmone and indole. These fragrance components can be widely used in various perfumes, soaps, balsams and daily cosmetic essences as main fragrances, and also modify many fragrances that are popular in the world, such as Su Xinlan, Violet, Mimosa and other fragrances. In terms of food, my country's nationa...
