Description

Technical Field

[0001] The invention relates to the technical field of peucedanum chinense processing, and in particular to a peucedanum chinense processing method. Background Art

[0002] First mentioned in the Ming Yi Bie Lu (Famous Doctors' Prescriptions), Peucedanum praeruptorum Dunn (a plant of the Umbelliferae family) is the dried root. It has the properties of reducing qi and resolving phlegm, dispersing wind and clearing heat, and is a common, bulky medicinal herb with high market demand. Currently, the majority of Peucedanum praeruptorum Dunn on the market is cultivated, but the quality of cultivated Peucedanum praeruptorum Dunn varies widely due to complex factors, including origin, germplasm type, cultivation method, and harvesting and processing.

[0003] Current processing of Peucedanum praeruptosae mainly involves removing impurities and drying the entire plant. However, large-scale artificially cultivated Peucedanum praeruptosae produces plants of varying sizes and numerous branches. The content of peucedanum praeruptosae in primary lateral roots is 1.20-1.24 times that of the main root, and 1.23-1.74 times that of the secondary root. The content of peucedanum peucedanum B in primary lateral roots is 1.10-1.16 times that of the main root, and 1.14-1.29 times that of the secondary root. The content of peucedanum peucedanum A in the surface layer of the root is 1.68-2.79 times that of the inner layer, and 1.74-2.78 times that of the inner layer. Peucedanum peucedanum A and peucedanum B in the surface layer have poor thermal stability, and prolonged heating will inevitably affect the quality of the final medicinal product.

[0004] The existing overall drying method fails to protect the processing quality of the medicinal materials according to the individual characteristics and component properties of the peucedanum. After the lateral roots and branch roots are completely dried, the main root cannot be dried in time, resulting in the loss of the index components on the lateral roots and branch roots due to continuous heating. In addition, the drying process as a whole is power-consuming and time-consuming, and the economic benefits are poor. Summary of the Invention

[0005] The purpose of the present invention is to provide a processing method for Peucedanum chinense, so as to solve the technical problems that the prior art fails to protect the processing quality of the medicinal material in a targeted manner according to the individual characteristics and component properties of Peucedanum chinense, the main root cannot be dried in time after the lateral roots and branch roots are completely dried, resulting in the loss of index components on the lateral roots and branch roots due to continuous heating, and the overall drying process is power-consuming and time-consuming, resulting in poor economic benefits.

[0006] The present invention discloses a method for processing Peucedanum peucedanum, comprising the following steps:

[0007] S1. Pre-processing the collected Peucedanum peucedanum;

[0008] S2. Grading and sorting the pretreated Peucedanum peucedanum;

[0009] S3. Multi-stage drying.

[0010] Furthermore, the pretreatment includes removing impurities, cleaning and airing.

[0011] Furthermore, the impurity removal is to spread the dug Peucedanum rhizomes flat on a processing and drying field, remove impurities and deteriorated rotten roots, and cut off the rhizome.

[0012] Furthermore, the cleaning is to keep the rhizome of Peucedanum peucedanum after impurities removal at a thickness of 15 to 20 cm, and then quickly wash away the dirt on the medicinal material with a high-pressure water gun.

[0013] Furthermore, the spreading and airing is to spread the cleaned Radix Peucedanum medicinal materials on a drying yard for 3 to 5 hours to dry the moisture attached to the surface.

[0014] Furthermore, the grading and sorting is to grade the pre-processed Peucedanum peucedanum according to size and then sort it.

[0015] Furthermore, the grading is based on a standard of 1.5 cm in thickness, and the herbs with main roots thicker than 1.5 cm are sorted into one pile, and their lateral roots are cut off and sorted into one pile together with the herbs with main roots less than 1.5 cm in thickness.

[0016] Furthermore, the multi-stage drying includes a first stage of primary drying and a second stage of direct drying.

[0017] Furthermore, both the first stage primary drying and the second stage direct drying are carried out by using forced air drying.

[0018] Furthermore, the first stage of initial baking is to place the graded and sorted Radix Peucedanum medicinal materials on trays according to the grading standards and place them in different baking rooms. The tray thickness is 15 to 20 cm, and the forced air drying is initially baked at a higher temperature of 75 to 80°C for 1 hour, and the fresh air volume in the drying room is 10 to 15 L / h.

[0019] Furthermore, the two-stage direct drying is to adjust the baking temperature in the blast drying room to 40-45° C., adjust the blast drying fresh air volume to 25-30 L / h, and take out the Radix Peucedanum when the moisture content is less than 12%.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. Compared with existing processing technologies for Peucedanum peucedanum, the Peucedanum peucedanum processing method of the present invention fully considers the objective situation that Peucedanum peucedanum products vary in size and have many forks during production. By sorting and grading the product parts of different sizes and centrally loading and baking them, it can save more than 20% of electricity.

[0022] 2. Gradual baking also avoids the risk of degradation and transformation of target components caused by prolonged heating of small roots and lateral roots;

[0023] 3. A short period of high temperature can effectively reduce the activity of degradative enzymes, thereby better protecting peucedanum arborescens A and peucedanum arborescens B distributed in the surface layer and lateral roots. Direct drying at a lower temperature in the second stage avoids the risk of degradation and conversion of peucedanum arborescens A and peucedanum arborescens B due to excessively high temperature.

[0024] 4. The production processing system established by the present invention is stable and easy to operate, which guarantees the quality of the processed medicinal materials to the greatest extent and has high promotion value. DETAILED DESCRIPTION
