Description

Technical Field

[0001] The invention belongs to the technical field of traditional Chinese medicines, and specifically relates to a process for processing astragalus. Background Art

[0002] Astragalus is sweet and slightly warm in nature. It enters the liver, spleen, lung and kidney meridians. It has the effects of invigorating qi and strengthening the exterior, restraining sweat and preventing fall, supporting sores and promoting tissue regeneration, and promoting diuresis and reducing swelling. In the theory of the five elements of traditional Chinese medicine, spring corresponds to the liver. Therefore, regulating liver qi is very important for health preservation in spring. Astragalus is a good product for replenishing qi, it can play a certain role in replenishing qi in the spring season.

[0003] In the existing technology, the processing of existing Chinese herbal medicine slices has great differences in quality due to different production conditions and links, which directly affects the efficacy. The quality of the slices is related to many factors such as the origin, collection time, processing and storage. The quality varies greatly. The current processing technology used for Astragalus slices is to take Scutellaria baicalensis from the temporary storage room of medicinal materials and put it on the selection table to select the medicinal materials and impurities. Put the medicinal materials into the medicine washing machine and wash them until there is no mud and sand in the medicinal materials. After the surface is clean, it will be transferred to the medicine moistening process. Spray drinking water and cut it, and then dry it in a hot air circulation oven. This process is simple, and the quality of Astragalus slices varies greatly. The produced slices have large impurities, high moisture content, and are prone to mold. Summary of the invention

[0004] In order to solve the above-mentioned existing problems, the present invention provides an Astragalus membranaceus processing technology with stable process, consistent processing quality and enhanced medical effect of Astragalus membranaceus.

[0005] The technical solution adopted by the present invention is as follows: The Astragalus membranaceus processing process of the present invention comprises the following steps:

[0006] S1 Screening: Pick out impurities that cannot be used as medicine, and sieve out broken leaves and soil blocks;

[0007] S2 Dry in the shade: Spread out the astragalus and dry it in a cool place to make it soft;

[0008] S3 Cleaning: Use a high-pressure washer to wash away the dirt, dust, mildew and other impurities on the surface of the dried astragalus root;

[0009] S4 Slicing: Use a planer to clean the skin of both sides of the Astragalus, and cut the Astragalus with the peeled edges into slices with a thickness of 2 to 4 mm;

[0010] S5 Steaming: Spread the Astragalus slices flat in a steamer, steam for 10 minutes, then take out the Astragalus slices and let them cool;

[0011] S6 Drying: Put the steamed Astragalus slices into a dryer for drying at a temperature of 65°C;

[0012] S7 repeats: repeat the above steps S5 and S6 to make the water content of the astragalus slices reach below 5%.

[0013] Furthermore, step S5 and step S6 are repeated 9 times.

[0014] Furthermore, the astragalus is selected from astragalus that is more than three years old, has a rhizome larger than 2 cm, a complete surface, and a net weight between 1-2 kg.

[0015] Furthermore, the astragalus slices in step S4 are divided into round slices and oblique slices.

[0016] Furthermore, after the astragalus slices are dried, the residual slices, rotten slices and impurities are picked out and packaged.

[0017] The beneficial effects achieved by the present invention using the above structure are as follows: the Astragalus processing process proposed in this scheme significantly improves the quality of Astragalus, the content of each effective ingredient meets the requirements, and the moisture content is controlled below 5%, so that the Astragalus slices are dried and easy to store.
