The application of fluidized bed spray granulation in preparation of Fengliao Changweikang sugar-free capsules was evaluated by using the orthogonal test.The flue gas temperature and flow, the relative d. of extract and the speed of spraying were determined to screen the optimal technol.The optimal conditions for the preparation of Fengliao Changweikang sugar-free capsules were obtained as follows: the relative d. of extract was 1.25, the flue gas temperature was 80°, the speed of spraying was 40 mL/min, and the gas flow was 1400 m³/h.This method was simple and automated for the present preparation of traditional Chinese medical pharmaceuticals.
