Embodiment 1
[0028] Example 1: Weigh and mix the medicinal materials according to the above table, add water to decoct twice, add water for the first time to 8 times the weight of the medicinal materials, decoct for 1 hour, add water for the second time to 6 times the weight of the medicinal materials, and decoct for 1 hour , combined decoction, filtered, the filtrate was concentrated to a relative density of 1.10 (65°C), added an appropriate amount of ethanol to make the alcohol content (volume fraction) reach 65%, stirred, left to stand for 24 hours, filtered, the filtrate recovered ethanol and concentrated to The extract with a relative density of 1.20 (65°C) is spray-dried (conditions are that the inlet air temperature is 100°C, the outlet air temperature is 80°C, the material temperature is 70°C, the atomization pressure is 0.2 MPa, and the spray speed is 5ml / s.), crushed into dry extract powder, added auxiliary materials, mixed uniformly in a granule mixer, granulated according to co...
Embodiment 2
[0032]Embodiment 2: Weigh and mix the medicinal materials according to the above table, add water to decoct twice, add water for the first time to 10 times the weight of the medicinal materials, decoct for 1.5h, add water for the second time to 8 times the weight of the medicinal materials, decoct 1.5h, combine the decoction, filter, concentrate the filtrate to a relative density of 1.15 (65°C), add an appropriate amount of ethanol to make the alcohol content (volume fraction) reach 75%, stir, let stand for 24 hours, filter, recover the ethanol from the filtrate and The extract concentrated to a relative density of 1.25 (65°C) is spray-dried (conditions are that the inlet air temperature is 120°C, the outlet air temperature is 90°C, the material temperature is 80°C, the atomization pressure is 0.3 MPa, and the spray speed is 7.5 / s.), crushed into dry extract powder, added auxiliary materials, mixed evenly in a granule mixer, granulated according to conventional methods, and mad...
