Problems solved by technology

[0003] Agarwood is traditionally extracted by steam distillation, which takes a long time and the active ingredients are easily destroyed; it is also extracted by organic solvents such as ethanol, gasoline or petroleum ether, which has the problem of flammable and explosive hazards and organic solvent residues
Therefore, unfavorable factors such as low quality, high energy consumption and large pollution severely limit the development and application of agarwood and jiexiang.

Abstract

The invention discloses an aquilariae lignum resinatum grease extraction and separation method and aquilariae lignum resinatum fragrance extraction and separation equipment. The method is characterized in that supercritical carbon dioxide extraction equipment and molecular distillation equipment are combined to extract and obtain aquilariae lignum resinatum grease-containing mixed extract by virtue of a specific extraction and separation process, and then to separate and obtain aquilariae lignum resinatum essential oil and aquilariae lignum resinatum grease cream through a molecular distillation process. According to the method and the equipment, the yield of the aquilariae lignum essential oil and the aquilariae lignum resinatum grease cream is at least doubled compared with that achievedby another distillation method, the original fragrance of aquilariae lignum resinatum grease is maximally maintained in terms of quality, solvent pollution is avoided, the development requirement ofpure natural chemical essence for daily use can be met, and broader market prospect is achieved.

Description

technical field [0001] The invention relates to the field of purification of natural plant spices, in particular to a method and equipment for extracting and separating agarwood. Background technique [0002] Agarwood trees are trees of the genus Aquilaria (Aquilaria) (Aquilariasinensis (Lour.) Gilg) and the same genus (Aquilria agallocha Roxb.) of the family Thymelaeaceae. When the trunk is bitten by insects, natural disasters or man-made damage, it will automatically secrete oil in the trunk. This is also the self-healing property of trees in nature. Gradually, this oil will emit a strange fragrance, and this brown-black oil on the trunk is agarwood. Because of its unique fragrance, it is often used in the preparation of spices and perfumes. [0003] Agarwood is traditionally extracted by steam distillation, which takes a long time and the active ingredients are easily destroyed; it is also extracted by organic solvents such as ethanol, gasoline or petroleum ether, which...
