Processing method for repeatedly drying rhizoma gastrodiae

Abstract

The invention discloses a processing method for repeatedly drying rhizoma gastrodiae, comprising the following steps: drying rhizoma gastrodiae in two different environments at different temperatures in turn, making temperature for primarily drying higher and temperature for secondarily drying lower, then standing the dried rhizoma gastrodiae in the environment at specific temperature and humidity, making the temperature and time for drying each time different so as to prevent the effective ingredient in rhizoma gastrodiae from damaging and to enable the water content therein to quickly reach the needed standard, wherein few folds are produced on the surface of rhizoma gastrodiae since the drying time is short; putting the dried rhizoma gastrodiae in the environment at specific temperature and humidity, automatically adjusting water content and surface property properly when influenced by temperature and humidity so that the final product is uniform in color, good in color of finished product and coherent in water content. The method can be used for processing rhizoma gastrodiae; and the water content in every 500 g of the rhizoma gastrodiae product is not more than 38 g.

Description

technical field [0001] The invention relates to a processing method of Gastrodia elata, in particular to Gastrodia elata. Background technique [0002] Gastrodia elata is a precious perennial parasitic herbaceous orchid medicinal plant, which was first recorded in "Shen Nong's Herbal Classic". It is flat in nature and sweet in taste, rich in "vanilla alcohol" and vitamin A. Muscles and bones, analgesic and anticonvulsant effects, have a good effect on headaches caused by liver wind and brain nervous system diseases caused by influenza virus; Gastrodia elata can also be used to lower blood pressure, slow down heart rate, increase cardiovascular output, and help Enhance memory, protect and regulate the human nervous system, and enhance the resolution of the optic nerve. Traditional Chinese medicine is used to calm the liver and calm the wind, calm convulsions and relieve pain. It is often used to treat convulsions in children, rheumatic pain, dizziness, headache, neurasthenia...

AI Technical Summary

Problems solved by technology

The existing processing methods of Gastrodia elata are generally sun-dried, smoked, and dried by fire. The processing time is long and the operation is cumbersome. Not only is it difficult to guarantee the appearance and quality of Gastrodia elata, but also greatly reduces the medicinal value of Gastrodia elata

[0004] The prior art also provides a freeze-dried Gastrodia elata processing method. Although this method can effectively retain the heat-sensitive substances contained in Gastrodia elata, the freeze-drying method has low drying rate, long time, and high energy consumption in the process. The investment in equipment is huge, and it is difficult to adapt to mass production. In addition, during the freeze-drying process, due to different freezing methods, the shape and size of ice crystals produced will also be different, which will easily affect the subsequent drying rate and quality of freeze-dried items.
