Description

Technical Field

[0001] The invention relates to the field of preparation of polygonatum sibiricum tablets, and more particularly to equipment and a process for preparing de-astringent polygonatum sibiricum tablets. Background Art

[0002] Polygonatum sibiricum is a traditional Chinese medicine belonging to the Monocotyledons of the Liliales order. It has the effects of replenishing qi and nourishing yin, strengthening the spleen, moistening the lungs, and benefiting the kidneys. It is often used to treat symptoms such as spleen and stomach qi deficiency, fatigue, insufficient stomach yin, dry mouth and poor appetite, lung deficiency and dry cough, hemoptysis due to exertion, insufficient essence and blood, soreness of the waist and knees, premature graying of hair, internal heat and thirst. During the processing of Polygonatum sibiricum, it is generally dug in spring and autumn, and then the roots are removed, washed, and then put into boiling water for a short blanch or steamed until thoroughly cooked, and then dried. At present, many Polygonatum sibiricum processing methods process Polygonatum sibiricum into slices. However, the existing equipment for slicing Polygonatum sibiricum needs to pause the transmission action during slicing, and then continue slicing after slicing is completed. In the slicing process, the sliced Polygonatum sibiricum is easily adhered to the cutter. If slicing is performed with a dynamic cutting tool such as a cutting wheel, the Polygonatum sibiricum slices will splash, and the quality of the Polygonatum sibiricum slices will be reduced after collision.
