Processing method of prepared rehmannia root

Abstract

The invention provides a processing method of prepared rehmannia root. The method comprises the following steps: a, slicing dried rehamnnia root, drying the dried rehamnnia root for 2 to 3 hours at 50to 70 DEG C, putting the dried rehamnnia root into a turning steamer while the dried rehamnnia root is hot, adding yellow wine, and ensuring that 30 to 50kg of yellow wine is used for each 100kg of dried rehamnnia root; performing covered moistening for 0.5 to 1 hour, and performing steaming with steam; b, performing insulation stewing for 0.5 to 1 hour after steam is closed, and then taking outthe dried rehamnnia root; c, performing drying at 50 to 70 DEG C through a through flow oven, ensuring that the drying thickness is 5 to 10cm, and continuously drying the dried rehamnnia root for 40 to 50 hours, so as to obtain the prepared rehmannia root. The method has the advantages that the time for stewing with wine is short, the dried rehamnnia root is easy to be thoroughly stewed, and energy is saved; the adoption of the turning steamer is beneficial to sufficient steaming of prepared rehmannia root medical herb in pieces, and the purpose of processing is achieved; through the adoptionof the through flow oven, the drying speed is high, the drying process is not affected by weather, bacterium is not easy to breed, the prepared rehmannia root is not easy to go mouldy and go bad, thelabor intensity is small, and the method is beneficial to industrial mass production. The whole processing technical period is short and is approximately 2 to 3 days. The technology is stable, the content of effective components is high, and the method is suitable for industrial mass production.

Description

technical field [0001] The invention relates to a processing method of Rehmannia glutinosa. Background technique [0002] Rehmannia glutinosa is the dried tuber root of Rehmannia glutinosa Libosch., a plant of the family Scrophulariaceae. It is dry and cold in nature and has the functions of clearing heat and cooling blood, nourishing yin and promoting body fluid. In order to expand the scope of its clinical application, it needs to be processed to change its coldness and increase its benefit effect. There are many processed products of Rehmannia glutinosa, among which Rehmannia glutinosa is recorded in the 2015 edition of the Chinese Pharmacopoeia, which is the most widely used processed product in clinical practice. [0003] The processing method of rehmannia glutinosa recorded in the 2015 edition of "Chinese Pharmacopoeia" is as follows: (1) Take rehmannia glutinosa, stew it with wine (general rule 0213) until the wine is exhausted, take it out, and dry it in the air unt...

AI Technical Summary

Problems solved by technology

[0006] At present, the stewing time of rehmannia rice wine is long, it is not easy to stew thoroughly, and the energy consumption is high; the drying process is easy to breed a large number of bacteria, the drying time is easily affected by the weather, and it is easy to mold and deteriorate; the drying process is labor-intensive, and the drying is limited by the site, which is not conducive to large-scale industrial production; Long production cycle (about 5-7 days)
