Atractylodes macrocephala processing method

Among the products of Atractylodes macrocephala, the quality of Atractylodes macrocephala is far better than that of cultivated products, so it is listed as a single species. However, due to the scarce resources of Atractylodes macrocephalae, cultivated Atractylodes macrocephala has become the mainstream of the commodity. Its quality is personal, fat and strong, with few branches, high quality and not vacuous. Among the Atractylodes macrocephala produced in various places, the top grade produced in Zhejiang is superior to other producing areas. It is one of the famous "Eight tastes of Zhejiang" authentic medicinal materials. Atractylodes macrocephala is harvested around the beginning of winter when the stems of the plants turn yellowish brown, the lower leaves are yellow, and the upper leaves are hardened. There are two methods of drying and sun drying.

The product obtained by the drying method is "drying technique" or "kang technique". It takes 3 times to dry the kang to get the finished product: the first drying kang, the temperature is about 80 ℃, 4-6 hours later, turn it up and down to make fine roots Fall off; when the kang is 80% dry at a temperature of 60℃-70℃, take it out and store it for 6-7 days to make the internal moisture overflow and the outer skin softened, and then dry it at a temperature of 50℃-60℃. When baking kang, the key lies in controlling the temperature according to the degree of dryness and wetness of Atractylodes macrocephala. It is necessary to prevent high temperature and rapid drying and soaking and scorching, and not to dry at low temperature for a long time until the oil is simmered.

Baking: It is hard in texture, dark in appearance (compared to raw tanning), and the section is slightly keratinous, with cracks, and slightly chrysanthemum pattern. Most of the products in the main producing areas, such as Zhejiang and Hunan, are processed into baking products, which are mainstream varieties.

The product obtained from the sun-drying is a raw sun-dried technique, and the fresh Atractylodes macrocephala can be dried repeatedly, but it takes a long time and should be protected from freezing. It is already winter when it is processed, so it is also called winter surgery. However, winter surgery is easy to oil and difficult to preserve. Some people slice winter surgery and top with mineral ash.

Sunshine technique: The texture is waxy and soft, and the cut noodles are white or yellowish white. It is compact and has no cracks or very fine cracks, and it is conservative and wet. This processing method is mostly used in Anhui, Hunan, Yuyao, Ninghai, Xianju, Fenghua and other places.

Among the two products of drying technique and raw drying technique, drying technique is the mainstream processing variety because it is easy to store and not easy to send oil. However, drying technique is often prone to internal hollowness and scorching due to the good quality of the drying process. Although the sun drying technique is waxy, dense and oily, it is prone to oily due to the heat and humidity of the storage environment, so it is not easy to store.
