Embodiment 1
[0038]Take the medicinal material of Erigeron lanceolata, coarsely pulverize it into a coarse powder of about 100 meshes, and then ultrafinely pulverize it into a powder in which 90% of the particles in the ultrafine powder have a particle size less than or equal to 41 μm, add ethanol-water solution (the mass fraction of ethanol is 20%) ) soft material by wet method, the ratio of solution to superfine powder is 0.5:1 (by weight), after mixing, pre-installed 20-mesh sieve, the extrusion speed is 50r / min, and the extrusion force is 1MPa to make wet granules. The wet granules were transferred to a hot air circulation oven, the drying temperature was set at 80°C, and dried for 2.5 hours until dry.
