Processing technology for fresh-cut radix polygonati officinalis medicinal slices ready for decoction

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine processing, and in particular relates to a processing technology of Polygonatum odoratum fresh-cut decoction pieces. Background technique [0002] The dry rhizome of Polygonatum Polygonatum is long cylindrical, slightly flat, with few branches, 4-18cm long, 0.3-1.6cm in diameter, yellow-white or light yellow-brown surface, translucent, with longitudinal wrinkles and slight The raised link has white dot-shaped fibrous root scars and disc-shaped stem scars, hard and brittle or slightly soft, easy to break, cuticle-like or granular, slightly odorous, sweet, sticky when chewed, and Sweet in taste, slightly cold; returns to lung and stomach meridians; nourishes yin and moistens dryness, produces body fluid and quenches thirst; used for lung and stomach yin injury, dry-heat cough, dry throat and thirst, internal heat and quenching thirst.

Problems solved by technology

[0004] According to the records of Chinese Pharmacopoeia, Polygonatum odoratum is excavated in autumn, removes the fibrous roots, washes, sun-dries until soft, rubs repeatedly, air-dries until there is no hard core, and then dries; or after steaming thoroughly, kneads until translucent, and dries; Finally, the rhizome of Polygonatum odoratum without fibrous roots is kneaded by hand until it starts to become transparent, and it is better for the sugar juice to overflow and stick to the hands. The method is related. The original operation of kneading sugar refers to the process of repeatedly rubbing the dried and softened Polygonatum odoratum with hands to make it translucent. However, this process is time-consuming and laborious, and it is not easy to operate and control.

[0005] The Chinese Pharmacopoeia method is cumbersome to operate, the production cycle is long, the efficiency is low, and the active ingredients are easy to lose during the moistening process; in the prior art, the traditional Chinese medicinal materials are washed and dried with non-circulating hot air, and Polygonatum odoratum is easy to change color; there is no size classification before drying, and different sizes The drying time of the medicinal materials is inconsistent, which affects the quality of the medicinal materials; the medicinal materials are moistened, resulting in the loss of active ingredients
