Embodiment
[0020] Embodiment: the production of superfine ginkgo powder
[0021] Take 50 kilograms of whole herb (moisture content 8.5%), first select impurities, wash with cold water, dry in the air, chop into 3-5 cm long, and dry in a far-infrared oven at a temperature of 50-60°C for 30 minutes. Minutes later, quickly raise the temperature to 100°C, dry for 30 minutes, cool down naturally at normal temperature, store for 4 hours, the moisture content of the medicinal material is 2.6%, and then grind at normal temperature (20-35°C) in three stages (the first stage of mechanical crushing: The average particle size is about 800-1200 microns, the second stage of mechanical crushing: the average particle size is about 300-500 microns, and the third stage of airflow ultrafine grinding: the average particle size is below 10 microns) to obtain the ultrafine powder of hook kisses. Finally, in an environment with a relative humidity of less than 60% at 20±2°C, use high-density polyethylene packa...
