Embodiment 1

[0033] Embodiment 1 The detailed drying method of the present invention is investigated

[0034] Remove the fibrous roots of the fresh rhubarb palmate or rhubarb tangut, scrape off the rough skin, cut into sections of about 3 cm, and dry them as follows:

[0035] a. Dry in the shade String the herbs together and place them in a ventilated and cool place to dry.

[0036] b. Sun-dried The medicinal materials are dried in the sun.

[0037] c. Drying The medicinal materials are placed in an electric blast drying oven and dried at 45°C.

[0038] d. Microwave drying Use household microwave ovens to dry medicinal materials, take them out every 5 minutes, put them at room temperature, and weigh them.

[0039] e. Far-infrared drying Use a far-infrared radiation drying oven (45°C, radiation distance 25cm) to dry the medicinal materials.

[0040] f. Drying under reduced pressure Use a vacuum drying oven (vacuum degree -0.09MPa, 45°C) to dry the medicinal materials.

[0041] g. Freeze...

Embodiment 2

[0100] The comparison of the rhubarb of embodiment 2 present invention and other technology preparations

[0101] By comparing the results in Table 9, the processing method of rhubarb of the present invention, compared with the processing method of rhubarb reported at present, the processing method of rhubarb of the present invention is time-saving, energy-saving, high in drying efficiency, low in cost, simple in method, standardized and easy to implement , The medicinal properties and chemical composition content meet the pharmacopoeia standards.

Abstract

The invention relates to a processing method of rhubarb. The processing method comprises the following steps of: a) taking a rhubarb fresh product, removing rough skin, and cutting into a section with the thickness of 2-3cm; b) continuously drying for 2-12 hours at the temperature of 40-80 DEG C, and cooling for 12 hours; c) continuously drying for 12-36 hours at the temperature of 40-80 DEG C, and cooling for 12 hours; and d) continuously drying for 6-18 hours at the temperature of 40-80 DEG C, and cooling for 24 hours to obtain the dry rhubarb. The processing method disclosed by the invention adopts three-section baking due to the existence of three drying rates with obvious differences. An intermittent way is adopted, cooling is performed in an oven, and the residual heat is utilized to achieve a new balance point so as to be conductive to natural diffusion of water, simultaneously avoid fast shrinkage on the surface of a medicinal material, which is caused by fast cooling outside a box, prevent affecting the next-stage drying and further achieve comprehensive utilization of energy. The processing method has the advantages of high efficiency, low energy consumption, and convenience and easiness in operation.

Description

technical field [0001] The invention relates to a processing method of rhubarb. It belongs to the field of medicine. Background technique [0002] Rhubarb is the dried root and rhizome of Rheum palmatum L., Rheum tanguticum Maxim.ex Balf. or medicinal Rheum officinale Baill. of the Polygonaceae plant. The effect of purging and attacking stagnation, clearing heat and purging fire, cooling blood and detoxifying, expelling blood stasis and dredging menstrual flow, promoting dampness and reducing jaundice, is used to treat constipation due to excess heat, sore mouth and tongue, diarrhea due to damp heat, vomiting due to stomach heat, heat-toxin sores, and vomiting blood , hemoptysis, epistaxis and other blood heat hemorrhagic diseases, as well as amenorrhea, postpartum stasis, accumulation of lumps, traumatic injuries, etc. [0003] Palm leaf rhubarb is also known as sunflower rhubarb, northern rhubarb, and Tianshui rhubarb; Tangut rhubarb is also known as chicken feet rhubarb...
