Description

Technical Field

[0001] The invention belongs to the technical field of glycyrrhizic acid processing and purification, and in particular relates to a purification device and method for glycyrrhizic acid processing. Background Art

[0002] Licorice is a perennial herbaceous plant of the Leguminosae family. It is a commonly used and indispensable Chinese medicinal material in clinical practice. Because it can harmonize hundreds of medicines and detoxify hundreds of poisons, it is known as the "national elder". Licorice was first recorded in the "Shennong Bencao Jing" and was called beautiful grass and dense sweet. It was listed as a top-grade product. It is believed that it can treat cold and heat evil spirits in the five internal organs, strengthen tendons and bones, grow muscles, double strength, treat wounds and swellings, and detoxify. The purification equipment used for glycyrrhizic acid processing is a complex and delicate system. It needs to be designed and selected by comprehensively considering multiple factors. Through reasonable equipment configuration and process optimization, efficient and pure production of glycyrrhizic acid can be achieved to meet the needs of glycyrrhizic acid in the pharmaceutical, food and other industries.

[0003] After searching, Chinese patent number CN214512828U discloses an automated controlled multifunctional extraction tank for producing licorice extract, including a shell, and adjustment mechanisms are installed below the left and right sides of the shell, the adjustment mechanism includes a square plate, a threaded rod, a concave plate, a handle and a support, and the inner side of the square plate is fixedly connected to the outer side of the shell. The handle in the adjustment mechanism drives the threaded rod to rotate, and then the square plate moves up and down inside the concave plate, so that the overall height of the shell can be adjusted, which meets the pipe connection of different needs, avoids conflicts, ensures normal connection, and improves use. Then, the licorice is put in, and it can be crushed at any time, eliminating the trouble of crushing in advance, and can be put in according to demand, solving the problem of inconvenient storage of licorice. The rotating long rod drives the stirring blade below to rotate inside the shell, which can stir the heated licorice, avoid the occurrence of wall sticking, and eliminate the trouble of cleaning, which is convenient for promotion and use;

[0004] However, in the above patent, since the stirring shaft cannot move, only fixed unidirectional stirring can be performed, which results in a too simple stirring method. Not only will there be problems of dead corners during the stirring process, but there may also be uneven stirring, resulting in reduced work efficiency, which in turn affects the subsequent purification efficiency. Summary of the invention

[0005] In view of the problems in the related art, the present invention proposes a purification device and method for glycyrrhizic acid processing to overcome the above technical problems existing in the existing related technology.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention realizes multi-directional movement of the stirring shaft during the stirring process through a transmission mechanism and a gear system. Specifically, the stirring shaft can not only rotate on its own, but also move up and down under the drive of a driving motor. This design enables licorice powder and solvent to be more fully mixed in the stirring barrel, thereby improving the purification efficiency. By combining horizontal stirring and vertical stirring, dead angles in the stirring process can be broken, ensuring uniform mixing of licorice powder and solvent, which is conducive to the full dissolution and extraction of glycyrrhizic acid, thereby improving the quality and purity of the product.
