Problems solved by technology

Using this method to prepare essential oils can remove waxes well, but during distillation and concentration, it is easy to cause molecular rearrangement, oxidation, hydrolysis, polymerization, etc., resulting in the destruction of essential oil components, and it may also cause solvent residues. Affect the quality of essential oil

Embodiment

[0018] A kind of extraction process of lavender essential oil, comprises the following steps:

[0019] Step a. Pick fresh lavender, wash it with water, dry the lavender branches and leaves naturally in the shade, then add it to a stirring ball mill, and mechanically activate it at a speed of 300-500r / min for 5-10min to obtain lavender powder;

[0020] Step b. add sodium chloride solution according to the mass ratio of powder and water in the ratio of 1:5, and soak for 4-5 hours; wherein, the concentration of sodium chloride solution is 20%-25%;

[0021] Step c. Transfer to the distillation device for atmospheric distillation, pass water vapor from the bottom of the distillation tank to heat the extract, raise the temperature to 110°C-125°C, extract the extract for 1.5-2h after boiling, and obtain mixed steam; to the condensate Drop it on a glass plate, get an oil-water mixture after condensation, and stop distillation when no oil drops appear;

[0022] Step d. oil-water separ...

Abstract

The invention provides an extraction technique of lavender essential oil. The technique comprises the following steps: picking and cleaning, naturally drying in the shade, activating and pulverizing; adding a sodium chloride solution, and immersing; carrying out atmospheric distillation, and boiling the extracting solution; obtaining a condensate; carrying out oil-water separation; adding an ethanol solution into an activated carbon adsorption column to extract oil in the activated carbon adsorption column, thereby obtaining crude oil; and extracting, stratifying, and separating out the supernatant, thereby obtaining the lavender essential oil. The organic solvent for extraction is the ethanol solution which can be thoroughly volatilized in the extraction process, so the product does not have ethanol residues and does not have any toxic or harmful effect on the human body. The lavender essential oil can be used for preparing cosmetics, washing supplies, medicines and the like, and thus, has wide application range.

Description

technical field [0001] The invention relates to an essential oil extraction process, in particular to a lavender essential oil extraction process. Background technique [0002] Lavender (Lavandula angustifolia Mill) is a plant of the genus Lavandula Linn in the Labiatae family. It is a perennial herb or a semi-shrub. It is known as "the queen of aromatic herbs". Native to the coast of the Mediterranean Sea and the islands of Oceania. It is distributed in China, Russia, Australia, the United States and South America, and has a long history of cultivation and application. my country introduced lavender as early as 1952, mainly distributed in Xinjiang, Shaanxi, Jiangsu and other places. Lavender leaves, stems, and flowers all have aroma, especially the aroma of flowers is rich and soft, non-irritating, and non-toxic and side effects. Therefore, it is widely used in medicine, aromatherapy, cosmetics, washing, and food industries. Fragrances, insect repellents and raw material...
