The invention belongs to the technical field of
processing of traditional Chinese medicines, and particularly relates to a
processing technology for fresh-
cut radix polygonati
officinalis medicinal slices ready for decoction. The
processing technology comprises the steps of (1) grading, wherein dug fresh radix polygonati
officinalis is graded into a large-size grade, a medium-size grade and a small-size grade according to the
rhizome size; (2) thorough washing, wherein the fresh radix polygonati
officinalis of the same grade is placed in a medicinal material washing
machine, and after
silt is removed thoroughly, the fresh radix polygonati officinalis is poured out; (3) cleaning processing, wherein a fibrous root removing
machine is adopted, fibrous roots of the radix polygonati officinalis are removed, and after the fibrous roots are thoroughly removed, the radix polygonati officinalis is washed thoroughly; (4),
cutting into slices and
drying, wherein the radix polygonati officinalis is
cut into the slices, and the slices are poured in a baking pan, flat spread uniformly and conveyed into a
nitrogen charging dryer for stage-type heating
drying; (5) screening and packaging, wherein dried radix polygonati officinalis pieces are screened and stored in a ventilated and dried
cool storage. The thoroughly washed radix polygonati officinalis is directly
cut, a
wetting process is saved, and the loss of effective components is reduced; the
nitrogen charging dryer is adopted for
drying treatment to avoid the oxidation
stain phenomenon of the radix polygonati officinalis, and the
drying time is shortened; a stage-type heating method is adopted for drying, it is avoided that the radix polygonati officinalis pieces warp, so that the radix polygonati officinalis pieces are more attractive, and the quality of the radix polygonati officinalis pieces is ensured.
