NOVELTY - Preparing hair dye with black hair function, comprises taking 10-30 wt.% fleece-flower root powder, 5-25 wt.% black sesame, 5-15 wt.% dandelion, 3-10 wt.% ginger, 10-20 wt.% rhizoma gastrodiae, 3-10 wt.% graphene, 1-3 wt.% hydrogen peroxide, 1-5 wt.% citric acid and pure water, and transporting the raw material to the side of the preparation device, adding the part of the raw material without special adding requirement into the central mixing tank, mixing the main raw materials in the central mixing tank to react to the proper stage, grinding the refine and the particulate matter, circulating the mixed solution in the central mixing tank through the circulating side pump, transporting the processed hair dye raw liquid to the color mixing device, adding color mixing raw material according to the requirement, after uniformly mixing the hair dye, filling and sealing the hair dye by the packaging device. USE - The method is useful for preparing hair dye with black hair function. ADVANTAGE - The method can make the hair quality of the hair more supple through the hair dye of pure plants, and reduces the problems of dull hair color and itchy scalp of dyed hair, can also replenish the color of the hair without accidental dyeing, and hydrogen peroxide and citric acid increase the absorbency of the dyed hair without causing scalp loss and hair fall. DETAILED DESCRIPTION - Preparing hair dye with black hair function, comprises (i) taking 10-30 wt.% fleece-flower root powder, 5-25 wt.% black sesame, 5-15 wt.% dandelion, 3-10 wt.% ginger, 10-20 wt.% rhizoma gastrodiae, 3-10 wt.% graphene, 1-3 wt.% hydrogen peroxide, 1-5 wt.% citric acid and pure water, and transporting the raw material to the side of the preparation device, (ii) adding the part of the raw material without special adding requirement into the central mixing tank (1) through the feeding port (2), and synchronously starting the stirring motor to primarily mix the raw material in the central mixing tank, and grinding the refine and the particulate matter in the raw material by the grinding cone block (320) in the raw material mixing process, (iii) mixing the main raw materials in the central mixing tank to react to the proper stage, circulating the mixed solution in the central mixing tank through the circulating side pump (401), and circulating the mixed solution in the mixed solution circulation, sequentially adding the auxiliary material to the inner part of the central mixing tank by mixing the feeding barrel (403) and the upper opening (404) of the feeding material, (iv) adding all kinds of raw materials to the central mixing tank (1), and mixing all raw materials in the central mixing tank and reacting, introducing the raw material in the central mixing tank into the discharging tank (601) through the discharging middle pipe (5), cooling the mixture to the proper temperature, discharging the mixed hair dye through the discharging bottom pipe (619), and collecting the hair dye by the collecting container and temporarily sealing and storing, and (v) transporting the processed hair dye raw liquid to the color mixing device, adding color mixing raw material according to the requirement, after uniformly mixing the hair dye, filling and sealing the hair dye by the packaging device.
