Description

Technical Field

[0001] The utility model relates to a segmented tube-extracting machine for Polygala tenuifolia. Background Art

[0002] Polygala is one of the commonly used Chinese medicinal materials, but the core of Polygala has side effects and must be extracted when used for medicine. The Polygala strips before extraction are in the shape of a long cylinder, slightly thicker at the top and thinner at the bottom, with a reed head at the top, 20 to 40 cm long. The Polygala meat is wrapped around the outside of the Polygala core. After pre-processed Polygala, the core of Polygala is hard but tough. The so-called extraction is to separate the Polygala meat from the internal core. The more complete the Polygala meat after peeling, that is, the Polygala tube, the better.

[0003] At present, the extraction of Polygala tenuifolia is still mainly done by manual rubbing and core removal. Although there are some extraction machines on the market, most of them are of low quality. Some cannot be completely extracted and need manual assistance for secondary extraction. Some even break the Polygala tenuifolia tube into pieces. The quality of incomplete broken Polygala tenuifolia tubes is reduced, which seriously affects the sales price. Utility Model Content
