Description

TECHNICAL FIELD

[0001] The present application relates to the field of traditional Chinese medicine harvesting and processing, and particularly relates to a processing method of Bletilla striata rhizome and a processing device thereof. BACKGROUND

[0002] Bletilla striata (Thunb.) Reichb.f. is the dried rhizome of Bletilla striata, also known as Bletilla striata, which is a perennial herbaceous medicinal plant. Bletilla striata has the effects of astringing and hemostasis, and promoting tissue regeneration. In clinical practice, Bletilla striata has remarkable effects on treating hemoptysis, scalding, hemorrhage, ulcer pain, trauma bleeding, hematochezia, fissured hands and feet, carbuncle, and anal fissure. In pharmacological activity, Bletilla striata also has the pharmacological activities of antioxidant, anti-inflammatory, antibacterial, antitumor, anti-fibrosis, anti-ulcer, promoting wound healing, and promoting cell growth. Bletilla striata rhizome contains various chemical components, among which Bletilla striata polysaccharide is the main component in Bletilla striata rhizome. With the deepening of the understanding of the chemical components and pharmacological activities of Bletilla striata and the development of Bletilla striata functional products, the demand for Bletilla striata is increasing. In order to meet the increasing demand for Bletilla striata, people increase the artificial planting of Bletilla striata.

[0003] As the material basis of traditional Chinese medicine, the quality of traditional Chinese medicinal materials is the guarantee of the clinical efficacy of traditional Chinese medicine. Artificial planting is the main source of traditional Chinese medicinal materials, and the quality of artificially planted traditional Chinese medicinal materials is affected by many factors.

The white baneberry in the white baneberry planting demonstration area is transplanted in March 2020, and the planting area is 1000m 2 2 years old in 2021. In mid-September 2021, at the above experimental site, white baneberry plants with basically the same growth vigor were selected from the same white baneberry experimental plot, with a test area of 4m x 2m, containing 114 nests of white baneberry plants in each test area, and 3 replicates were set for each treatment.

[0053] The control group does not grade the collected white baneberry tubers, and after 30 minutes of fixation at 110°C, they are dried at 70°C to a constant weight, crushed with a crusher, and mixed evenly through a 60-mesh sieve for use. The test group classifies the white baneberry tubers according to the size of the flat spherical surface, into large tubers, medium tubers, small tubers, and tubers outside the grade. A group of large tubers, medium tubers, and small tubers are boiled in boiling water until there is no white core, then removed and dried in a cloth bag at 70°C to a constant weight. Another group of large tubers, medium tubers, and small tubers are fixed at 110°C for 30 minutes in an oven, then dried at 70°C to a constant weight, crushed with a crusher, and mixed evenly through a 60-mesh sieve for use.

[0059]

[0060] In order to accelerate fixation or death, in some embodiments, the white baneberry tubers are sliced, and the graded white baneberry tubers are fed through a feeding hopper, fall onto a conveyor belt, and are conveyed to the other end of the conveyor belt, then fall onto a slicing knife holder. Due to the angle of the slicing knife holder, the white baneberry tubers continue to roll down until they come into contact with the slicing knife holder and the conveyor belt at the same time, and are moved downward under the drive of the conveyor belt, and are sliced by the knife until the end. The thickness of the slices can be controlled by setting the distance between the knives.
