【Abstract】 In view of the fluidization operation,one of the industrial production technologies,the operational performance is analyzed in brief and the typical process flows are also shown.Based on it,several application and development examples of this type technology in the present grain and oil product processing are enumerated around the two process operations of drying and pyrolysis,respectively.Furthermore,concerning the quantitative control of material residence time,the relative deficiency is discussed and the preliminary improvement direction is proposed.The concrete suggestion can be summarized as the systemic engineering design should be performed for material residence time by combining with the analyses of equipment structure and dimension,the simulations of flow field in bed and the calculations of heat and mass transfer velocities.更多还原
