Problems solved by technology

The traditional processing method is to dry or air-dry, which takes a long time, is easily affected by the weather, and is not easy to preserve; in order to make the Astragalus medicinal material more beautiful and easier to store, grassroots processors often use sulfur to fumigate the medicinal material of Astragalus membranaceus, but sulfur fumigation of Chinese medicinal materials not only Affecting the quality of the medicinal material itself will also introduce a variety of harmful substances, causing serious harm to human health

Embodiment 1

[0014] Example 1 Pretreatment method of Astragalus medicinal materials (removal of impurities, classification)

[0015] After harvesting, the fresh astragalus membranaceus is removed from impurities, residual stems and reed heads, and classified according to three grades with diameters of 3 cm, 2 cm, and 1 cm and below.

Embodiment 2

[0016] Example 2 Traditional drying group The Radix Astragali medicinal material that has been processed by embodiment 1 is tiled respectively according to different grades and is aired and dried in the sun or dried in the shade indoors, and the weight change is always recorded until the moisture content of the medicinal material is below 10%.

Embodiment 3

[0017] Embodiment 3 hot air processing group : The Radix Astragali medicinal material processed by embodiment 1 is respectively placed in an electric heating constant temperature blast drying oven according to different grades, and is dried at 60°C, 70°C, and 80°C respectively until the moisture content is about 46%, then taken out, cooled slightly Straight, continue to bake at the same temperature until the moisture content is below 10%, take it out, let it cool, and it’s ready. According to different drying temperatures, it is divided into hot air 60°C processing group, hot air 70°C processing group and hot air 80°C processing group.

Abstract

The invention discloses a processing method for drying a medicinal material radix astragali by hot air and microwave combination, aiming at the technical problems in the prior art that not only is the quality of medicinal materials affected but also various harmful substances can be brought in when traditional Chinese medicines are fumigated with sulfur. The method comprises the following steps: impurity removal, grading according to the size, hot air drying, smoothing straight, hot air drying, microwave drying, chilling, tidying, binding and tying and subpackaging. The method can achieve the aim of drying the medicinal material radix astragali faster. Compared with traditional methods, the method has the beneficial effect that the moisture content of the medicinal material can fast reach the limit stipulated in Chinese Pharmacopoeia on the basis of not reducing the main ingredients of the medicinal material. Compared with a sulfur fumigation method, the method has the beneficial effect that the harmful substances are prevented from being brought in. Meanwhile, the method has the beneficial effects that the medicinal material radix astragali has obvious effects on improvement of immunities of mice; mildewing, damages caused by worms and other phenomena are not easy to happen in the storage process; the stability of the quality of the medicinal material radix astragali is ensured; radix astragali processing is more normalized through tidying and subpackaging, thus improving the quality controllability of the medicinal material radix astragali.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine processing, and specifically relates to a method for drying and processing Radix Astragali medicinal materials. Background technique [0002] Astragalus is the dried root of the leguminous plant Astragalus mongolica or Astragalus membranaceus. As a traditional Chinese medicine, Astragalus is widely used. It is used in a large amount in clinical Chinese medicine and has a high yield. Astragalus is produced in Gansu, Shaanxi, Shanxi, Inner Mongolia, Anhui and Heilongjiang. The traditional processing method is to dry or air-dry, which takes a long time, is easily affected by the weather, and is not easy to preserve; in order to make the medicinal material of Astragalus more beautiful and easier to store, grass-roots processors often use sulfur to fumigate the medicinal material of Astragalus, but fumigation of traditional Chinese medicinal materials with sulfur is not only Affecting the q...
