Abstract

The invention discloses a method for processing skin-whitening and freckle-removing powder by using largehead atractylodes rhizome flowers. The largehead atractylodes rhizome flowers are crushed at a low temperature after being frozen and dried. Compared with the largehead atractylodes rhizome flowers crushed at normal temperature, the largehead atractylodes rhizome flowers crushed at low temperature have better liquidity, more ideal granularity distribution, higher crushing speed and higher efficiency, effectively inhibit the biological, chemical and physical changes of the thermosensitive substances, avoid damage to active ingredients of the largehead atractylodes rhizome caused by high temperature of the mechanical rotation in the normal crushing process, and keep the original nutrition, colours and active substances of the largehead atractylodes rhizome flowers to the largest extend. The abandoned largehead atractylodes rhizome flowers are processed into the superfine skin-whitening and freckle-removing powder, so the income for a peasant who plants the largehead atractylodes rhizome is increased, a new beautifying material is provided for the cosmetic market, and a purely natural beautifying product is further provided for women.

Example Embodiment

[0009] (1), wash and dry: Remove the calyx and pedicel from the picked fresh Atractylodes macrocephala flowers, pick out the leaves and sundries, rinse the flowers with clean water, and dry them for later use;
[0010] (2) Pre-freezing: Spread the washed and dried Atractylodes macrocephala on the tray, turn on the refrigeration compressor of the freeze dryer to pre-cool the freezer, and when the temperature of the freezer reaches -15°C, place the tray Put it into the freeze-drying chamber, set the freezing temperature to -25°C, and freeze for 30 minutes;
[0011] (3) Frozen sublimation: the frozen Atractylodes macrocephala is in a sublimation state, the temperature is controlled at -20°C--30°C to freeze into a solid state, and the drying vacuum is maintained at 10-15 Pa;
[0012] (4) Dehydration and drying: increase the temperature of the shelf under the tray, gradually increase the temperature to 30°C-35°C, and continue for 10-14 hours, so that the moisture content of Atractylodes macrocephala can reach 5%;
[0013] (5) Coarse powder treatment: first crush the freeze-dried Atractylodes macrocephala into coarse powder particles with a particle size of 2.0 mm to 2.4 mm, which is convenient for ultra-fine crushing;
[0014] (6), ultra-fine grinding: send the coarse powder particles into the feeding port of the air-flow ultra-fine grinding machine, take the high-speed air flow as the power, the air flow speed is 350 m/s, and the speed of the classifying wheel is 6500 r/min, and the particles of Atractylodes macrocephala are crushed Ultrafine powder with a fineness of 1250 mesh.
