【Abstract】 Based on the flowing characteristic of gas and particle in the Z-path moving bed, theoretical analysis and experiment of drying process in the Z-path moving bed have been conducted. Millet is adopted as drying material. Results show that Z-path moving bed can be used to dry granular material. The proposed process has the advantages of high quality product, energy saving and easy control.And mathematical simulation was well corresponding with the experiment result.更多还原
