Based on the theoretical analysis of flow characteristics between superheated steam and granules materials in the fluidized bed drying chamber, the fluidization experiment with superheated steam and hot air was conducted by using the dried rapeseed particles as the experimental material. A small experimental device was established. The experimental results showed that the operating velocity of superheated steam fluidized bed drying was faster than the traditional hot air fluidized bed dying under the same conditions. Under the given conditions, the critical fluidization velocity of the rapeseed particles was 1.26m/s during superheated steam fluidized bed drying.
