Problems solved by technology

[0004] In summary, the traditional methods for extracting aroma components mainly have the following disadvantages: 1) The extraction temperature is high, the loss of aroma components with low and medium boiling points is large, and the aroma of the product is significantly different from that of natural materials; 2) Only water-soluble 3) The solvent is easy to remain in the extract, and if the solvent is impure, it will bring odor and affect product quality; 4) The equipment has high pressure resistance requirements, and the investment and energy consumption are relatively high. high

Abstract

The invention relates to a method and a device for extracting an aroma component. The method comprises the following steps of: (1) performing pretreatment on a material, and then performing pressure reduction treatment on the treated material in an extraction container; (2) introducing a solvent into the extraction container to mix the solvent and the material, and extracting the mixture to obtain extract liquor; (3) putting the extract liquor into a vaporization separation device to separate out a crude extract of the aroma component, and simultaneously separating the solvent, compressing and cooling the solvent, and then reclaiming the solvent for cyclic utilization; and (4) putting the crude extract of the aroma component into a refining system to perform refining treatment to prepare a refined extract. The extraction device comprises an extraction separation system, the refining system, a solvent purification system, a vacuum system and a heat exchange system. The aroma component extracted by the method and the device has no solvent residue, and the effective active components of a natural plant raw material can be maintained to the utmost extent.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, and in particular relates to a method and equipment for extracting aroma components. Background technique [0002] At present, the methods for extracting aroma components from natural plants mainly include pressing and grinding, distillation, solvent extraction, supercritical CO 2 extraction, ultrasonic extraction, etc. The pressing and grinding method has a narrow application range and is more suitable for fresh fruits, especially citrus, but it is not effective for dry plant materials. The operation temperature of the distillation method is higher, the time is longer, and the loss of low boiling point and water-soluble components is large. Supercritical CO 2 The extraction method has high requirements on the withstand voltage of the equipment and is only suitable for the extraction of non-polar substances. Ultrasonic extraction is still in the laboratory stage, and there is still a c...
