Embodiment Construction

[0014] figure 1 , figure 2 Shown is the specific method of extracting anethole from 989 kilograms of natural anise oil. This method includes the extraction of crude anethole and the extraction of refined anethole in two steps:

[0015] Extraction of Crude Anethole:

[0016] A sample was taken from 989 kg of natural fennel oil for chromatographic analysis. The analysis result was: the content of anethole was 84.2%, and the freezing point was 13.7°C. Put the raw material of fennel oil into a container and put it in a freezer to freeze to -13°C to make it solid. Use a crusher to crush the fennel oil solid into a powder with a particle size of less than 1.5 mm, and then put it in a centrifuge for separation. , put it into a centrifuge for separation for 4 minutes to obtain 522 kg of solid crude anethole with lower purity and 467 kg of the first mother liquor when the temperature rises to the point where the oil overflows from the hands, and the solid crude anethole contained i...

Abstract

The invention discloses an extracting process method for anethole. The extraction process method adopts natural anise oil as an extracting material, and comprises a step of extracting crude anethole and a step of extracting fine anethole; the extracting of the crude anethole comprises freezing the natural anise oil to solid, crushing the solid and separating out the crude anethole by a centrifugal machine; and the extracting for the fine anethole comprises four steps, wherein in the first step, the temperature of a distillation kettle is 110 DEG C, the temperature of the top of a distillation tower is 50 DEG C, and a reflux ratio is 10 to 1; in the second step, the temperature of the distillation kettle is 130 DEG C, the temperature of the top of the distillation tower is 110 DEG C, and the reflux ratio is 20 to 1; and in the third step, the temperature inside the distillation kettle is 140 DEG C, the temperature of the top of the distillation tower is 115 DEG C, and the reflux ratio is 0 to 1 until the collected distillate reaches the amount of the analyzed and calculated anethole. The method can solve the problems that the fraction is lost in the extracting process of the natural anethole, and the quality of the anethole is poor.

Description

technical field [0001] The invention relates to the technical field of forest product industry, in particular to a process for extracting natural anethole from star anise raw materials. Background technique [0002] Fennel oil is a colorless or light yellow liquid with a special smell of fennel. Its main component is anethole, with a content of 80% to 90%, and contains acetaldehyde and other substances. Anethole is mainly used in daily chemicals (such as toothpaste etc.), food, tobacco flavoring agent and medicine, etc. [0003] At present, one method of extracting anethole from fennel oil in industrial production is distillation, because it is usually operated at high temperature, resulting in fraction loss and poor quality of anethole. Contents of the invention [0004] The purpose of the present invention is to provide a natural anethole extraction process, which can solve the problems of fraction loss and poor quality of anethole in the natural anethole extraction pro...
