Extraction equipment for essential oil of orange osmanthus flower and extraction method thereof

Abstract

The invention discloses extraction equipment for essential oil of orange osmanthus flower and an extraction method thereof. The extraction equipment comprises an extraction chamber, wherein a fragrance releasing working box and a fragrance suction device are respectively arranged in the extraction chamber, a plurality of layers of trays are arranged in the fragrance releasing working box and are made of screen nets, and circulating fans are arranged among the plurality of layers of trays; the fragrance suction device comprises an air blowing mechanism, the air blowing mechanism is arranged at the exterior of the extraction chamber and is connected with a vacuum pump arranged in the extraction chamber, one end of the vacuum pump is connected with an air inlet of the fragrance releasing working box, the other end of the vacuum pump is connected with an activated carbon adsorption column, the activated carbon adsorption column is connected with a fragrance suction pipeline, and the input end of the fragrance suction pipeline is connected with an air outlet of the fragrance releasing working box; a moisture-suction condensing mechanism is arranged at the part, near the activated carbon adsorption column, of the fragrance suction pipeline. Compared with the prior art, the extraction equipment has the advantages that the design is reasonable, the extraction is quick, the operation is simple and convenient, the fragrance is rich, the purity is higher, the amount of chemical solvent residues in the sucked-out fragrance is very small, and the influence to the human body is avoided.

Description

technical field [0001] The invention relates to the technical field of essential oil extraction, in particular to an extraction equipment and an extraction method of osmanthus fragrans essential oil. Background technique [0002] Osmanthus osmanthus is a kind of precious natural spice. The active ingredient osmanthus osmanthus essential oil is widely used in various products of food and cosmetics as a high-grade spice. , promoting qi and relieving pain, dispersing blood and stopping dysentery, dispelling bad breath and other effects. It is also an excellent mood booster and air freshener. At present, the commonly used extraction methods of volatile oil from Osmanthus fragrans are steam distillation (SD) method and solvent extraction (SE) method. The SD method is simple to operate, low in cost, and has a large extraction amount. However, some heat-sensitive substances or unstable substances in the high-temperature process It is easily hydrolyzed and destroyed, and the obtai...

At present, the commonly used extraction methods of volatile oil from Osmanthus fragrans are steam distillation (SD) method and solvent extraction (SE) method. The SD method is simple to operate, low in cost, and has a large extraction amount. However, some heat-sensitive substances or unstable substances in the high-temperature process Easily hydrolyzed and destroyed, the obtained essential oil has poor aroma and low purity

The SE method is fast and easy to operate, but the extract is often mixed with residual chemical solvents, and the aroma is not natural and fresh enough, which is likely to have adverse effects on the human body
