Abstract
The invention relates to a method for extracting essential oil from jasmine flowers, belonging to the field of natural plant processing. The method comprises the following steps: adding fresh jasmine petals in olive oil to soak with a ratio of material to solvent being 1:1.5 to obtain a mixture; carrying out centrifugation on the mixture to obtain a flower solution, then filtering the flower solution; injecting the flower solution into an extraction device through a feeding device, closing the valve of the feeding device, and then carrying out vacuum pumping on the extraction device; adding an extractant in the extraction device, and then carrying out extraction repeatedly to obtain an extract liquor; transferring the extract liquor into an evaporation plant, separating the solvent from the extract, and then purifying. The method has the characteristics of simple technology, safety, health, and high oil yield.
Description
Technical field
The present invention relates to a kind of method of from Flower of Arabian Jasmine, extracting essential oil, belong to the natural phant manufacture field.
Background technology
Jasmin quintessence oil is called as " king of essential oil ", has conditioning reproductive system, drying and responsive skin, and the desalination scar increases beneficial features such as skin elasticity.Jasmin quintessence oil has graceful smell, and has tangible relaxation effect, can inspire enthusiasm, and is a kind of active drug of treating serious depression; It also has better curative effect to the disease of treatment respiratory system, can weaken cough, and is also effective in cure to hoarseness and laryngitis.In addition, can also alleviate myalgia with it, sprain the symptom stiff with four limbs; Jasmin quintessence oil is fit to the skin of nursing drying, oiliness, pungency and susceptibility, increases the elasticity of skin.Yet the oil yield of jasmin quintessence oil is low, and about 8,000,000 Flower of Arabian Jasmine just can extract 1 kilogram of essential oil, and extraction process is also very complicated.
Summary of the invention
In view of the defective that prior art exists, the purpose of this invention is to provide a kind of method of from Flower of Arabian Jasmine, extracting essential oil, this method technology is simple, safety and sanitation and have higher oil yield.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of method of from Flower of Arabian Jasmine, extracting essential oil, described process for extracting is realized through following steps:
1) with soaking in the fresh jasmine petal adding sweet oil, material dissolves and compares 1:1.5;
2) after the mixture that step 1) is obtained carries out spinning, the colored water of gained is filtered;
3) with step 2) the colored water that obtains injects through feeding unit injection extraction plant, close the valve on the feeding unit after, extraction plant is carried out vacuum pumping;
4) in extraction plant, carry out extraction process repeatedly behind the adding extraction agent, extraction time 1h, temperature 30-50 ℃, pressure 0.6-0.8MPa;
5) the gained extraction liquid being transferred in the evaporation unit, is that solvent separates the back purification with extract.
Extraction process repeatedly described in the step 4) is: after finishing first extraction, feed liquid is depressed in the evaporation unit, in extraction plant, adds once more and the feed liquid in the evaporation unit is transferred to extraction plant behind the extraction agent and carries out reextraction; Described extraction process carries out six times at least.
Import in the solvent cycle device behind the described vaporizer, the compression back that lowers the temperature imports in the extraction plant and recycles.
The plucking time of described fresh jasmine petal is no more than 72h.
Soak time described in the step 1) is 72h at least.
The invention has the beneficial effects as follows: a kind of method of from Flower of Arabian Jasmine, extracting essential oil, described process for extracting is realized through following steps:
1) with soaking in the fresh jasmine petal adding sweet oil, material dissolves and compares 1:1.5;
2) after the mixture that step 1) is obtained carries out spinning, the colored water of gained is filtered;
3) with step 2) the colored water that obtains injects through feeding unit injection extraction plant, close the valve on the feeding unit after, extraction plant is carried out vacuum pumping;
4) in extraction plant, carry out extraction process repeatedly behind the adding extraction agent, extraction time 1h, temperature 30-50 ℃, pressure 0.6-0.8MPa;
5) the gained extraction liquid being transferred in the evaporation unit, is that solvent separates the back purification with extract.
This method technology is simple, safety and sanitation and have higher oil yield.
Embodiment
A kind of method of from Flower of Arabian Jasmine, extracting essential oil, described process for extracting is realized through following steps:
1) with soaking in the fresh jasmine petal adding sweet oil, soak time is 96h, and material dissolves and compares 1:1.5;
2) after the mixture that step 1) is obtained carries out spinning, the colored water of gained is filtered;
3) with step 2) the colored water that obtains injects through feeding unit injection extraction plant, close the valve on the feeding unit after, extraction plant is carried out vacuum pumping;
4) in extraction plant, carry out extraction process repeatedly behind the adding extraction agent, extraction time 1h, temperature 30-50 ℃, pressure 0.6-0.8MPa;
5) the gained extraction liquid being transferred in the evaporation unit, is that solvent separates the back purification with extract.
Extraction process repeatedly described in the step 4) is: after finishing first extraction, feed liquid is depressed in the evaporation unit, in extraction plant, adds once more and the feed liquid in the evaporation unit is transferred to extraction plant behind the extraction agent and carries out reextraction; Described extraction process carries out six times.
Import in the solvent cycle device behind the described vaporizer, the compression back that lowers the temperature imports in the extraction plant and recycles.
