In the paper, we theoretical analysis the gas-particle flow behaviors in the drying chamber. Then establish a small experimental device and conduct a comparative fluidization experiment with superheated steam and hot air, which the dried rapeseed particles are the experimental material. The critical fluidizing velocity of the rapeseed particles in superheated steam is 1.26 m/s in the experimental condition. The experimental results show that the inlet operating flow velocity of superheated steam fluidized bed drying is greater than which of the traditional hot air fluidized bed dying under the same conditions.

Proper drying methods can prevent the damage of food grains by changing in physic-chemical properties and minimize the spoilage during storage and improve the nutrition quality of grain. Thus proper drying methods are very important to choose based on operating conditions and cost. In present work, the typical variations in physico-chemical properties of mustard seeds obtained from Varshakonda Village in Telangana State were investigated during drying in Hot Air Oven, Tray Drier and Fluidized Bed drier. Removal of moisture during fluidized bed drying is observed very effective. Also, nutritional properties like fat, protein, phosphorous & iron contents were found to decrease considerably low during drying in Fluidized bed comparatively in hot air oven and tray drier. Therefore, mustard seeds can effectively dried in Fluidized Bed. The fluidization characteristics of mustard seeds under different operating conditions were investigated in order to find out best drying method to dry mustard seeds.

The objective of the study is to investigate the effects of different drying processes (convective hot air, microwave, and fluidized bed drying) and combined drying methods on the drying characteristics and physical properties of the dried wheat and the power consumption of the dryers. The lowest moisture content and water activity values were observed for the 25min of drying in fluidized bed dryer (60°C) and following 16min in microwave dryer (540W). The lowest power consumption was observed in the 60°C-180W fluidized bed-microwave combination (0.77kWh) compared to the other combined trials.
