Production technology of prepared rehmannia roots

Abstract

The invention discloses a production technology of prepared rehmannia roots. The technology is characterized by comprising selecting materials, performing detergent washing, performing detergent washing, performing alcohol wetting, performing steaming, slicing, drying and packaging. In the step of selecting materials, prepared rehmannia roots are graded, rehmannia roots processed at the same time are uniform in size, during alcohol wetting, yellow rice wine can be uniformly absorbed, steaming can be uniform during steaming, the interior and the exterior are consistent, during slicing, the prepared rehmannia roots are uniform in size and thickness, the finally produced prepared rehmannia roots are uniform in quality, and the curative effect is ensured; in the step of steaming, steaming juice is collected, the juice is sprayed to the prepared rehmannia roots again, and effective ingredient loss is avoided. In the step of slicing, purified water is used for spraying a cutter, the slice shape is stable, and slices are not likely to be stuck to the cutter; the technology further utilizes a novel steaming device for traditional Chinese medicine decoction pieces for drying, the continuous time of the whole drying process is greatly shortened, the processing time of prepared rehmannia roots is greatly shortened compared with a traditional technology, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the field of traditional Chinese medicine processing, in particular to a production process of Rehmannia glutinosa. Background technique [0002] Rehmannia glutinosa is a traditional Chinese medicine. It is the rhizome of Rehmannia glutinosa or Rehmannia huaiqing, which is processed and steamed.

AI Technical Summary

Problems solved by technology

In the rehmannia glutinosa obtained by the method of processing Rehmannia glutinosa provided by the invention, the content of verbascoside reaches 0.040-0.057%, which is significantly higher than the requirement of 0.02% in the 2010 edition of "Pharmacopoeia of the People's Republic of China". However, first, only two Second-time steaming, it is difficult to steam all the rehmannia glutinosa, and if the rehmannia glutinosa is not steamed, it may affect its medicinal properties from cold to mild, affecting the efficacy; the processing time is still long, which is not conducive to the large-scale production of rehmannia glutinosa; the cutting process It is a common cutting process, and the slices are easy to stick to the cutter, which will affect the shape of the slices
