Problems solved by technology

[0003] Using the existing Chinese herbal medicine processing technology, during the processing of Gastrodia elata, the active ingredients such as plant protein, microorganisms, and volatile oil will be damaged, especially in the traditional drying process, it is easy to be polluted, and the content of ash, microorganisms, and heavy metals is easy to exceed the standard; In addition, the current In the production process of traditional Chinese medicine drying, manual sorting, binding, kneading, drying, drying in the drying room and other processes are required. The workload is heavy, the cycle is long, the drying efficiency is low, and the labor cost is high, which greatly increases the cost of Chinese medicine decoction pieces.
