摘　　要：针对工业生产中的流态化操作技术,在简要分析了其操作特性及示例了典型工艺流程的基础上,分别围绕着干燥与热解两处理过程,列举了该类技术于当前粮油产品加工领域中的若干应用与研发实例.并重点就实际生产过程中物料停留时间的定量控制问题,探讨了相应的不足之处及提议了初步的改进方向,即宜结合设备结构尺寸的分析、器内流场的模拟及热质传递速率的计算等,进行物料停留时间的系统性工程设计.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.
