Embodiment 1
[0034] Preparation of dandelion granules: take dandelion decoction pieces, add water to decoct 3 times, add 8 times the amount of water each time, heat and decoct for 1.5 hours each time; combine the medicinal liquids, concentrate the filtrate to a clear paste with a relative density of 1.08 (80°C), Filtrate with a 350-mesh sieve while it is hot; spray dry under the conditions of air inlet temperature 175°C, material pump speed 500 rpm, outlet air temperature 90°C, and air supply temperature 40°C to obtain spray-dried powder; The hole diameter is 1.50mm, the roller motor frequency is 40HZ, the feeding motor frequency is 45HZ, and the oil cylinder pressure is 20bar under the conditions of dry granulation to obtain dandelion particles with a particle size of 40 mesh.
Embodiment 2
[0036] Preparation of traditional Chinese medicine preparations containing dandelion granules: Preparation of dandelion granules: take dandelion decoction pieces, add water to decoct 3 times, add 8 times the amount of water each time, heat and decoct for 1.5 hours each time; combine the medicinal liquids, and concentrate the filtrate to a relative density of 1.08 (80°C) clear paste, filter it with a 350-mesh sieve while it is hot; spray dry under the conditions of air inlet temperature 175°C, material pump speed 500 rpm, outlet air temperature 90°C, and air supply temperature 40°C , to spray dry powder; dry granulation under the conditions of punching plate aperture 1.50mm, roller motor frequency 40HZ, feeding motor frequency 45HZ, oil cylinder pressure 20bar, to obtain dandelion granules with a particle size of 40 mesh; mix 175g dandelion granules with 65g maltodextrin Mix well, add appropriate amount of magnesium stearate, mix well, and press into 1000 tablets.
Embodiment 3
[0038] A method for rapidly detecting the moisture content of dandelion particles based on near-infrared spectroscopy, specifically comprising the steps of:
[0039] a. Take dandelion particle samples, a total of 82 batches, about 3g each, grind into fine powder, put it into a stoppered glass sample bottle, place it on a near-infrared scanner for scanning, collect spectra, scanning conditions: scanning range 4000 -12000cm -1 , number of scans: 32 times, resolution 8cm -1 , the background is subtracted in real time during the scanning process, and 3 spectra are collected for each sample to obtain the following figure 1 The near-infrared original absorption spectrum figure of 82 batches of dandelion particles shown;
[0040] At the same time, according to the standard method stipulated in the 2015 edition of the Chinese Pharmacopoeia, its moisture content was determined by the drying method. About 2 g of dandelion particles ground into fine powder were spread in flat weighing ...
