Embodiment 1

[0023] A comprehensive utilization mode of traditional Chinese medicine dregs, which comprises the following steps:

[0024] (1) Raw materials: Take Radix Radix Radix Radix Radix Dregs as traditional Chinese medicine dregs.

[0025] (2) Extraction of polysaccharides: take the residue of traditional Chinese medicine, add water to decoct twice, each time for 3 hours, filter, combine the filtrate, evaporate and concentrate to 1 / 5 of the original volume, centrifuge, add 2 times the volume of 95% ethanol to the supernatant Precipitate, let it stand for 12 hours, centrifuge, and collect the precipitate. The precipitate was redissolved with water, deproteinized, and dried at 60°C to obtain Radix isatidis polysaccharide.

[0026] (3) Drying and pulverization: air-dry the traditional Chinese medicine dregs after extracting polysaccharides for 2 days, then dry them to make the moisture content of the traditional Chinese medicine dregs ≤ 10%, and then pulverize them into granules or pow...

Embodiment 2

[0030] (1) Raw material: Salvia miltiorrhiza Chinese herb residue.

[0031] (2) Extraction of polysaccharides: take the residue of traditional Chinese medicine, add water and decoct 3 times, 2 hours each time, filter, combine the filtrate, evaporate and concentrate to 1 / 5 of the original volume, centrifuge, add 4 times the volume of 95% ethanol to the supernatant Precipitate, let it stand for 24 hours, centrifuge, and collect the precipitate. The precipitate was redissolved with water, deproteinized, and dried at 60°C to obtain Danshen polysaccharide.

[0032] (3) Drying and pulverization: air-dry the traditional Chinese medicine dregs after extracting polysaccharides for 2 days, then dry them to make the moisture content of the traditional Chinese medicine dregs ≤ 10%, and then pulverize them into granules or powders.

[0033] (4) Biomass fuel preparation: The pulverized traditional Chinese medicine dregs are subjected to superheated steam treatment, and the steam temperatur...

Embodiment 3

[0036] (1) Raw materials: astragalus traditional Chinese medicine residue.

[0037] (2) Extraction of polysaccharides: take the residue of traditional Chinese medicine, add water to decoct twice, each time for 2 hours, filter, combine the filtrate, evaporate and concentrate to 1 / 5 of the original volume, centrifuge, add 2 times the volume of 95% ethanol to the supernatant Precipitate, let it stand for 24 hours, centrifuge, and collect the precipitate. The precipitate was redissolved with water, deproteinized, and dried at 65°C to obtain astragalus polysaccharide.

[0038] (3) Drying and pulverization: air-dry the traditional Chinese medicine dregs after extracting polysaccharides for 2 days, then dry them to make the moisture content of the traditional Chinese medicine dregs ≤ 10%, and then pulverize them into granules or powders.

[0039] (4) Biomass fuel preparation: The pulverized traditional Chinese medicine dregs are subjected to superheated steam treatment, and the stea...

Abstract

The invention discloses a comprehensive utilization method of traditional Chinese medicine residue, and the comprehensive utilization method comprises use in the aspects of extracting polysaccharide,drying and pulverizing, preparing biomass fuel for combustion, preparing graphene, and the like. The comprehensive utilization method effectively solves the problem of waste and environmental pollution of the traditional Chinese medicine residue, turns the traditional Chinese medicine slag into high value-added products, improves the utilization value of the traditional Chinese medicine slag, andrealizes the comprehensive utilization of the traditional Chinese medicine slag and the sustainable development of traditional Chinese medicine resources, and at the same time, by recycling of the traditional Chinese medicine residue, sewage and energy cost of pharmaceutical manufacturers can be greatly saved, the development trend of green environmental protection can be met, harmless treatment and resource utilization can be achieved, and the comprehensive utilization method has better ecological, economic and social benefits.

Description

technical field [0001] The invention relates to the field of comprehensive utilization of waste, in particular to a method for comprehensive utilization of traditional Chinese medicine dregs. Background technique [0002] my country is a big country of traditional Chinese medicine. With the development of traditional Chinese medicine, a large amount of waste of traditional Chinese medicine produced in the process of Chinese herbal medicine processing, raw material medicine and Chinese patent medicine production has become one of the social problems that cannot be ignored. The waste residues of traditional Chinese medicine are mostly composed of roots, stems, and leaves of plants, and contain a large amount of cellulose, hemicellulose, and lignin. At present, the planting area of ​​Chinese medicinal materials in my country is more than 2.4 million hectares, and the annual output of medicinal materials is about 70 million tons. In the process of industrialization of deep proc...
