Background
Cortex Mori is dry root bark of Moraceae plant, has effects of lowering blood pressure, promoting urination, calming and relieving pain, can be directly used as Chinese medicinal material after treatment, and has high medicinal value. The root of Moraceae plant is divided into three layers, the outer layer is bitter peel, and is yellow brown or red yellow; the middle layer is cortex Mori, which is the value of root of Moraceae plant; the inner layer is rhizome.
Cortex Mori has high economic value, and is extracted from root of Moraceae plant by removing bitter bark and peeling off cortex Mori and rhizome. At present, the method steps for extracting the cortex mori radicis from the roots of the plants of the family moraceae are all completed by manual operation: the bitter skin is usually scraped off little by a knife, and the cortex mori radicis and the rhizome are peeled off by cutting the cortex mori radicis with a knife and peeling the cortex mori radicis and the rhizome off by hand. However, the bitter leaves are tightly covered on the white mulberry root bark, the scraping efficiency by using a knife is low, the effect is poor, and the requirement on human resources is high. The cortex mori radicis tightly stripped and connected with the rhizome, the separation is difficult, the cortex mori radicis is only stripped by hands, the efficiency is low, and the cortex mori radicis is also easy to be injured.
