Production method for prepared rehmannia root decoction pieces

Abstract

The invention discloses a production method for prepared rehmannia root decoction pieces. The production method comprises seven steps of: fine sorting, washing and moistening, steaming to be soft, drying, moistening, slicing, and redrying, and a method for planting prepared rehmannia root is provided simultaneously and comprises seven steps of: seed selection for sowing, land selection and preparation, sowing, field management, topdressing, disease prevention and curing, and picking and processing. The production method is complied with the ancient processing, is superior to the traditional technique, high in production efficiency, high in yield and capable of saving energy, and suitable for large-scale industrial production, and capable of solving the deficiencies of a steam cooker that the temperature is difficultly controlled, the quality reject ratio is high and the loss is large, and the planting method is simple, low in cost, easy to popularize and capable of processing at the key growth and breeding stages of the prepared rehmannia root, the yield of the prepared rehmannia root can be greatly increased by comprehensively planting through combination of culturing measures on scientific and reasonable fertilizer, proper planting density and the like, the nutrient ingredients are high, the planted prepared rehmannia root is natural, green and healthy, and the pollution to the environment is also reduced.

Description

Technical field [0001] The invention relates to a production method of Rehmannia glutinosa decoction pieces, which belongs to the technical field of traditional Chinese medicine production. Background technique [0002] The decoction pieces of rehmannia glutinosa are included in the 2010 edition of the Chinese Pharmacopoeia. There are two processing methods used: “(1) take raw rehmannia, stew according to wine (Appendix II D) and stew until the wine is exhausted, take it out, and dry When the skin mucus is slightly dry, cut into thick slices or pieces, and dry. (2) Take the raw Rehmannia glutinosa, steam it according to the steaming method (Appendix II D) until it is dark, take it out, and when it is about 80% dry, cut into thick slices Or block, dry, and get it.” The new production process follows the ancient traditional processing, which is superior to the traditional process, has high production efficiency, high yield, energy saving, and is suitable for large-scale industrial ...
