Problems solved by technology

The traditional drying methods of Gastrodia elata include shade drying, sun drying, and oven drying, but these drying methods will affect the appearance of Gastrodia elata and the content of gastrodin
Because Gastrodia elata has important medicinal value and economic value, and the traditional drying process of Gastrodia elata can no longer meet the current demand, it is urgent to develop a gastrodia elata drying process that does not affect the active ingredients and appearance of Gastrodia elata and is easy to operate

Abstract

The invention provides a gastrodia elata drying technology, a gastrodia elata powder preparation technology and freeze-dried gastrodia elata and gastrodia elata powder obtained through the gastrodia elata drying technology and the gastrodia elata powder preparation technology. The gastrodia elata drying technology comprises the following step that fresh gastrodia elata is freeze-dried to obtain the freeze-dried gastrodia elata, wherein drying includes three stages; according to process parameters of the first drying stage, the heating temperature is 4-20 DEG C, the heating time is 5-15 h, andthe vacuum degree is 25-35 Pa; according to process parameters of the second drying stage, the heating temperature is 20-40 DEG C, the heating time is 4-12 h, and the vacuum degree is 15-25 Pa; according to process parameters of the third drying stage, the heating temperature is 40-60 DEG C, the heating time is 12-25 h, and the vacuum degree is 2-15 Pa. By means of the gastrodia elata drying technology, the loss of effective components can be reduced, and the gloss, smell and shape of gastrodia elata are maintained. A superfine smashing method is used in the gastrodia elata powder preparationtechnology, the process is simple in operation, and the prepared gastrodia elata powder is high in effective component content and uniform in particle size.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicine preparation, in particular to a gastrodia elata drying process, a gastrodia elata powder preparation process and the obtained freeze-dried gastrodia elata and gastrodia elata powder.
