Embodiment 1
[0042] Take 15g of cetyl alcohol and stearyl alcohol in a beaker, heat the beaker in a water bath at 85°C, add 10g of andrographolide after it melts, and stir for 30 minutes with a magnetic stirrer, so that the andrographolide is mixed with the mixture After suspending in stearyl alcohol, it is sprayed with hot melt.
[0043] The melt spray parameters are: air inlet temperature 130°C, atomization pressure 0.3Kpa, feed rate 80ml / min.
[0044] The hot-melt spray product is collected to obtain the flavored mixture of andrographolide. The mixture is mixed with fillers, flavors, sweeteners, sour agents and suspending agents in appropriate proportions to obtain the andrographolide dry suspension.
