The invention discloses a making method of a radix-
codonopsis broken-wall decoction piece. The making method comprises the following contents of first soaking a radix-
codonopsis medicinal material in a soaking solution, then oven-
drying a radix-
codonopsis decoction piece, and then crushing the radix-codonopsis decoction piece through a
crusher with a 100-mesh
sieve, so as to subsequently make medicinal-material coarse
powder of 80 to 120 meshes; afterwards, subjecting the medicinal-material coarse
powder to
microwave oven-
drying in sequence,
grinding the medicinal-material coarse
powder into ultrafine powder, afterwards, further carrying out
granulation through an
ethanol-water
wetting method, carrying out
extrusion molding at a certain rotational speed, and carrying out
drying, thereby making the radix-codonopsis broken-wall decoction piece. The radix-codonopsis broken-wall decoction piece provided by the invention is first soaked by adopting the soaking solution; the nutritive value of radix codonopsis is improved; the primary
processing is carried out; afterwards, the
granulation is further carried out through the
ethanol-water
wetting method; the grain of the made radix-codonopsis broken-wall decoction piece is better in grain type; the tightness is moderate; the stability is high; the disintegration is good; meanwhile, in comparation with a conventional ultramicro wall breakage crushing method, the making method is used for greatly improving the wall
breakage rate of the radix codonopsis; a
nutrient substance is maximally maintained; the beneficial effects that the wall
breakage rate is high and a nutritional ingredient is stored completely are achieved.
