Description
Technical field
The invention belongs to Chinese medicine preparation technical fields, and in particular to a kind of concocting method of efficient Rehmannia glutinosa.
Background technique
Glutinous rehmannia is the fresh or dried root of scrophulariaceae rehmannia glutinosa plant.Glutinous rehmannia is as one of the most common type Chinese medicine, in Chinese medicine
It is widely applied with having to compare in clinic.Radix rehmanniae recen is sweet in flavor, cold in nature, can be used for heat and enters ying blood, febrile virulent maculae, hematemesis and epistaxis
Deng.Radix Rehmanniae ecliptic longitude obtains Rehmannia glutinosa after processing, and Rehmannia glutinosa is sweet in flavor, slightly warm in nature, can be used for blood deficiency chlorosis, palpitation and severe palpitation etc..Glutinous rehmannia
In containing there are many chemical component, wherein glycoside and polysaccharide are the main active of glutinous rehmannia, have decompression, diuresis, protect painstaking effort
A variety of effects such as pipe.
Traditional glutinous rehmannia is a very important link using middle Processing methods.Root it is documented that, by radix rehmanniae recen big gun
The method that Rehmannia glutinosa is made is more, steam, wine system, ginger juice system, fructus amomi system, honey system etc..The processing of modern Rehmannia glutinosa is to steam, boil
Based on.Such as the nine of a kind of Rehmannia glutinosa of patent CN107213249 A steam nine concocting methods processed, the method steamed using nine times
Prepare Rehmannia glutinosa, but many workers in the industry think that the technique is loaded down with trivial details, time consumption and energy consumption, are not suitable for industrialized production.For
It improves and processes efficiency, a kind of patent CN 107773616A processing procedure of Rehmannia glutinosa, the system by the way of boiling in a covered pot over a slow fire system twice
Standby Rehmannia glutinosa, the technique greatly reduce the number that Rehmannia glutinosa steams, reduce cost.But this method single boils in a covered pot over a slow fire the time processed still
It is so longer, therefore highly efficient Rehmannia glutinosa processing procedure is developed, to the production cost for reducing Rehmannia glutinosa, reduce the city of Rehmannia glutinosa
Field price has great importance.
Summary of the invention
In order to further increase the processing efficiency of Rehmannia glutinosa, shorten concocted time, while guaranteeing the drug effect of Rehmannia glutinosa, this hair
It is bright that a kind of concocting method of efficient Rehmannia glutinosa is provided.The present invention is quick using infrared light, realizes sufficiently heating, improves active constituent
Conversion, shorten the time of subsequent processing, avoid effective component decomposition when brewed；Utilize the big gun for steaming joint freeze-drying
Technique processed, further shortens concocted time.
In order to achieve the above-mentioned object of the invention, the invention provides the following technical scheme:
A kind of concocting method of efficient Rehmannia glutinosa, which is characterized in that comprise the steps of:
(1) radix rehmanniae recen is cleaned, naturally dry, is sliced；
(2) rehmannia tablets are transferred in far infrared radiation drying equipment, using the dry 3-5 h of infrared lamp, are cooled to room temperature taking-up；
(3) rehmannia tablets after infra-red drying are transferred in Chinese medicine steaming machine, the water of 2-3 times of glutinous rehmannia quality is added, boil in a covered pot over a slow fire 30-45 processed
Then min steams 10-20min, is freeze-dried 1-2h after filtering；Again through it is stewing make-steam-freeze-drying process 2 times after to get
Rehmannia glutinosa.
Further, the size of glutinous rehmannia is not more than the cm of 2 cm × 3 after slice as described in step (1).
Further, main radiated wavelength range is 5~15 μm when far infrared radiation described in step (2), radiance
It is 0.90, radiant power is 300-500 W.
Further, the control of far infrared radiation temperature described in step (2) is at 90-110 DEG C.
Further, when first time boiling described in step (3), temperature is 65-80 DEG C；The temperature when freeze-drying
Degree is-55-- 70 DEG C.
Further, when second of boiling described in step (3), temperature is 55-70 DEG C, digestion time 30-35
Min, steaming time are 10-15 min;The sublimation drying is 1.5-2 h.
Further, when third time boiling described in step (3), temperature is 60-65 DEG C, digestion time 30-35
Min, steaming time are 10 min；The sublimation drying is 2 h.
Compared with prior art, a kind of concocting method of efficient Rehmannia glutinosa described in this patent has the advantages that
Method of the invention is easy to operate, and concocted time is short；It is quick using infrared light, it realizes sufficiently heating, improves turning for active constituent
Change, shortens the time of subsequent processing, avoid effective component decomposition when brewed；Utilize the processing work for steaming joint freeze-drying
Skill further shortens concocted time, while improving the conversion ratio of active constituent, avoids the decomposition of active constituent.Through the present invention
The glutinous rehmannia of preparation, active component content is high and processing procedure is easy to operate, is easy to industrial production.
