Abstract The technologies of one-step granulated Chinese traditional medicine drying tower were carried out within a spray drying agitated fluidized-bed drying tower. The operating characteristic of interval vented granule was presented and the drying mechanism was discussed. In addition, the author explained the reasons why to utilize low temperature, confirmed by experiments, in the tower, and the working principle and structural characteristic of four-channel nozzle, which was the drying mechanism of one-step granulated Chinese traditional medicine. And finally the author drew the conclusion that lower operating temperature and four-channel nozzle were the key factors to guaranteeing the credibility and facility of this mechanism.
