[0085] The preparation process of the notoginseng powder provided by the present invention is to obtain the notoginseng powder after the freeze-dried notoginseng obtained by the above-mentioned notoginseng drying process is ultrafinely pulverized, and the preparation process of the notoginseng powder has the same advantages as the above-mentioned notoginseng drying process In addition, it also has the advantages of simple operation and uniform particle size of Panax notoginseng powder after crushing.
[0086] In a preferred embodiment, the process parameters of superfine pulverization include: the material temperature is 2-20°C, the pulverization time is 3-15min, and the particle size of notoginseng after superfine pulverization is 200-550 mesh;
[0087] Typical but non-limiting examples of material temperature are 2°C, 3°C, 4°C, 5°C, 6°C, 7°C, 8°C, 9°C, 10°C, 11°C, 12°C, 13°C, 14°C, 15°C ℃, 16℃, 17℃, 18℃, 19℃ or 20℃;

Embodiment 1
[0113] A preparation process of Panax notoginseng powder, comprising the following steps:
[0114] (1) Cut fresh Panax notoginseng, cut off the fibrous root, cut mouth, Yanqi and bad seven parts of Panax notoginseng;
[0115] (2) Wash the fresh Panax notoginseng until there are no mud spots;
[0116] (3) Spread the washed Panax notoginseng evenly on the tray and place it in the tray trolley on the track. After placing it, transfer the tray trolley along the track to the quick-freezing warehouse. Close the quick-freezing warehouse. The freezing temperature is -35°C. Freeze to the core;
[0117] (4) Transfer the frozen notoginseng to the drying bin, turn on the vacuum unit and the refrigeration unit for vacuum drying, and the drying includes the first drying stage, the second drying stage and the third drying stage:
[0118] The process parameters of the first drying stage include: the heating temperature is 5°C, the heating time is 20h, and the vacuum degree is 25-30Pa;
