Method for preparing powder of Rehmanniae Radix preparata with short drying time and powder of Rehmanniae Radix preparata preapred therefrom

摘要

The present invention relates to a method for producing Rehmannia glutinosa powder with a reduced drying time and Rehmannia glutinosa powder prepared therefrom. More specifically, the present invention relates to a method for producing Rehmannia glutinosa powder and Rehmannia glutinosa powder prepared therefrom, which can prevent the problem of agglomeration of Rehmannia glutinosa powder containing moisture and sugar components during a grinding process, and at the same time, it is easy to control the particle size of the Rehmannia glutinosa powder without separation in the grinding process. In addition, it is possible to improve the powder yield, drying rate, and extraction yield of Rehmannia glutinosa powder.
