Abstract:
Objective: To study the optimal technological conditions of Ejiao granules by dry granulation. Methods: The effects of rolling wheel press, speed, and powder feeding rate on grain yield were studied, and the dry granulation technology for Ejiao granules was optimized using L9(34) orthogonal test. Results: The optimal granulating conditions for the roll pressure was 60-70 kgf/cm2, powder feeding rate was 17-19 r/min, and rolling speed was 10-12 r/min. Conclusion: The study on the dry granulation technology for Ejiao granules provides the experimental basis for industrial application and spread of dry granulation technology in Chinese animal medicines.
