Lavender is a genus of lavender, a perennial subshrub. The essential oil of lavender is excellent in quality and elegant and fragrant. It is known as the title of “King of Spices” and is an important raw material in the world. Lavender contains 35% essential oil. Lavender oil can clear away heat and detoxify, clean skin and control. Oil, whitening, whitening, wrinkle and skin rejuvenation, remove eye bags and dark circles, can also promote the recovery and recovery of damaged tissue and other skin care functions. Lavender essential oil has a calming effect on the heart, can reduce high blood pressure, soothe the heart, is very helpful for insomnia, currently Has been widely used in medical and health, daily chemicals, food processing and other fields.

 

The extraction method of lavender essential oil is mainly steam distillation method and organic solvent method. The existing water vapor has the problems of low extraction rate, long time consumption and low product purity. The solvent method not only needs to remove the leaching solvent, but also has the product. A large amount of residual solvent affects the odor and purity of lavender essential oil. In recent years, it has also been reported that supercritical carbon dioxide method and ultrasonic method are used to extract lavender essential oil, but these two methods have high equipment cost and are difficult to realize industrial production.

 

The method has the advantages of high extraction rate, high product purity, low cost, low energy consumption and short extraction time.

A method of extracting lavender essential oil, comprising the following steps:

(1) Mechanical activation: the lavender raw material is dried in the shade, added to the stirring ball mill, and mechanically activated for 5-10 minutes at a rotation speed of 300-500 r/min to obtain a lavender powder;

(2) Soaking: adding the above lavender powder to a glass reactor, and adding cellulase and water, the weight of the cellulase is 0.4-0.6% by weight of the lavender powder, and soaking at room temperature for 2_4 hours to obtain an extract;

(3) Distillation: heating the extract in the glass reactor, and extracting the liquid after boiling for 1.5-2 hours to obtain mixed steam;

(4) Condensation: the mixed steam obtained above is condensed by a glass reaction condenser, and condensed to obtain an oil-water mixture;

(5) Oil-water separation: the oil-water mixture obtained by condensation is separated by oil-water separator through oil-water separator to obtain lavender crude oil and water;

(6) Extraction: The obtained lavender crude oil is extracted through a double-layer glass reactor, and after separation, the upper layer is separated into lavender essential oil.

 

The role of the glass reactor in this production is very important, so the glass reactor buy and glass reactor use is important.

The method has the advantages of simple operation, short extraction time and low cost, and is suitable for industrial production.
