标题(英语)

Method for drying traditional Chinese medicine materials in mixing mode through microwave vacuum and hot air


摘要(英语)

A method for drying traditional Chinese medicine materials in mixing mode through microwave vacuum and hot air comprises placing the traditional Chinese medicine materials in a microwave vacuum drying stove, drying the traditional Chinese medicine materials for 3 to 5 minutes under the condition that the vacuum ranges from 0.07Mpa to 0.09Mpa and the unit microwave power ranges from 3W to 5W, delivering the traditional Chinese medicine materials into a hot air dryer, drying the traditional Chinese medicine materials for 1 to 3 hours under the temperature ranging from 70 DEG C to 90 DEG C, and finally delivering the traditional Chinese medicine materials to the microwave vacuum drying stove again for drying under the condition of the first step till the end. The method adopts mixing of the microwave vacuum drying and the hot air drying, enables the internal structure of the traditional Chinese medicine materials to achieve the effect of swelling, loosening and cracking, improves exudation ratio of decoction of liquid medicine and shortens decoction time without damaging contents of the traditional Chinese medicine materials. Further the method can keep intrinsic body integrity of the traditional Chinese medicine materials, reduces contractibility rate of the traditional Chinese medicine materials, accelerates rehydration of the traditional Chinese medicine materials, improves product quality and reduces energy consumption.
