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

Embodiment 1

[0020] Wash the fresh baiji and steam it in a cooking pot at 90°C for 5 minutes, so that the steamed baiji has no raw heart, then spread it out to cool down to room temperature, and the skin has no moisture; The steel needles with a diameter of 0.5mm, a length of 4cm, and a distance of 1cm are used to punch holes so that the pores penetrate the white and the whole body; then the drying is carried out by gradually increasing the temperature. The temperature is raised to 50°C at the speed of 2.5°C / 24h, and then the temperature is raised to 60°C at the speed of 2.5°C / 24h. The dried fibrous roots are broken under the impact of each other until they fall off from the roots of Baiji. The medicinal material prepared by this method has small overall deformation, bright color, smooth surface and no wrinkles. The polysaccharide content of Baiji is 31%.

Embodiment 2

[0022] Wash the fresh baiji and steam it in a cooking pot at 95°C for 5 minutes, so that the steamed baiji has no raw heart, then spread it out to cool down to room temperature, and the skin is free of moisture; put the cooled baiji with Steel needles with a diameter of 0.75 mm, a length of 6 cm, and a spacing of 0.5 cm are used to punch holes; then, drying is carried out by gradually increasing the temperature. , then raise the temperature to 60°C at a rate of 4°C / 24h, keep warm until the moisture content of the brine is ≤15%, and the whole process takes 126 hours; finally, put the dried brine into a grinder for rubbing and grinding, so that the dried fibrous roots are mutually Break off under impact until it falls off from the root tuber. The medicinal material Baiji prepared by the method has small overall deformation, bright color, flat and smooth surface without wrinkles, and the polysaccharide content of Baiji is 33%.

Embodiment 3

[0024] Wash the fresh baiji and steam it in a cooking pot at 100°C for 4 minutes, so that the steamed baiji has no heart, then spread it out to cool down to room temperature, and the skin has no moisture; put the cooled baiji with The steel needles with a diameter of 1mm, a length of 8cm, and a distance of 0.75cm are used to punch holes so that the pores penetrate the white and the whole body; and then dry by gradually increasing the temperature. The temperature is raised to 50°C at a speed of 5°C / 24h, and then the temperature is raised to 60°C at a rate of 5°C / 24h, and the temperature is kept until the moisture content of the white powder is ≤15%. The dried fibrous roots are broken under the impact of each other until they fall off from the roots of Baiji. The medicinal material prepared by this method has small overall deformation, bright color, smooth surface and no wrinkles. The polysaccharide content of Baiji is 32%.

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...
