The invention discloses a preparation method of multicoloured leaf
powder, and relates to the technical field of multicoloured leaf
powder preparation. The preparation method of the multicoloured leaf
powder comprises the following steps: S1, taking fresh multicoloured leaves, cleaning,
drying, putting the dried leaves into a crushing cylinder, chopping and juicing the same; S2, fully crushing the multicoloured leaves, pouring the multicoloured leaves out of the mixing drum, mixing the multicoloured leaves with a crushed material for
cell crushing and deionized water according to a fixed weight ratio, and placing the mixed liquid in a water bath at 50-70 DEG C for 35-50 minutes to obtain a mixed liquid for later use; and S3, putting the mixed liquid into a centrifugal cylinder for
centrifugation, and concentrating the centrifugate to control the
sugar degree to be 8-15, so as to obtain the multicoloured leaf juice. According to the preparation method of the multicoloured leaf powder, the transmission mechanism is matched with the crushing mechanism, so that waste caused by incomplete crushing of the multicoloured leaves by the crushing
barrel due to adhesion of the uncrushed multicoloured leaves on the inner wall of the crushing
barrel in the chopping process of the multicoloured leaves is prevented, and the influence of the incompletely crushed multicoloured leaves on preparation of the multicoloured leaf powder is prevented.
