Rhizoma bletillae drying method

Abstract

The invention discloses a rhizoma bletillae drying method, and belongs to the technical field of preliminary processing of a medicinal plant. The method comprises the following steps: cleaning fresh rhizoma bletillae, steaming and cooling the rhizoma bletillae, perforating the rhizoma bletillae through needle puncture, drying in a mode of gradually heating up and grinding to remove fibers so as to obtain the dried medicinal material. By heating the rhizoma bletillae until no raw flavor exists through steaming, the drying method can reduce the loss of water-soluble rhizoma bletillae polysaccharide; by perforating the rhizoma bletillae through needle puncture, the drying method can increase water diffusion channels in the rhizoma bletillae body so as to shorten a drying time; and by grinding after drying, the drying method can rapidly remove rhizoma bletillae fibers; compared with a conventional method drying in the sun, the method can be used for improving external and internal qualities of the panax stipuleanatus, and simultaneously, the method can be used for shortening the drying time by 5-8 days; and meanwhile, such problems as high amount of labor used, large occupied area of a drying yard in the sun, easy pollution and the like are solved.

Description

technical field [0001] The invention relates to a blanching and drying method, which belongs to the technical field of primary processing of medicinal plants. Background technique [0002] Bletilla striata (Bletilla striata) is the dry tuber of the orchid plant Bletilla striata, which is a perennial herbaceous bulbous plant. It is a traditional Chinese medicinal material. It is widely used clinically to treat hemoptysis, hematemesis, traumatic bleeding, sore swelling, chapped skin, tuberculosis, hematemesis, ulcer bleeding and other diseases. , "Materia Medica Collection Notes", "Plant Names and Facts" and "Pharmacopia" are all recorded. [0003] The main medicinal ingredient in Baiji medicinal material is Baiji polysaccharide, so increasing the content of Baiji polysaccharide is an important way to improve the quality of Baiji medicinal material. The main processing method of Baiji is as follows: wash the tubers of Baiji with water to remove the soil, peel off the rough b...

AI Technical Summary

Problems solved by technology

The main processing method of Baiji is as follows: wash the tubers of Baiji with water to remove the soil, peel off the rough bark and fibrous roots, put them in a boiling water pot to boil or scald until there is no white heart inside, take them out and cool them, and dry them in the sun; this method exists 4 Disadvantages ①Small workshop production, low degree of mechanization, small scale of steaming or cooking, and cooking caused serious loss of white jelly; ②The fibrous roots of white jelly are seriously fibrous, and fresh fibrous roots have greater toughness, so manual removal Time-consuming and labor-intensive; ③The drying process lasts for 13~15 days; ④The sanitary conditions are poor, because the drying place occupies a large area, it is difficult to prevent insects, rats, dust and other pollution
