摘　　要：食品干燥流化床是食品工业中应用最广泛的设备之一,最小流化速度是流化床干燥器中最关键的设计运行参数之一。本文综述了最小流化速度基本方程的获得方法,分析了4种最小流化速度关联式基本方程的推导思路,阐述了最小流化速度基本方程的研究进展,厘清了最小流化速度基本方程的通用形式之间的相互关系、化简方式及推广方法,总结推荐了3组通用基本方程用于拟合最小流化速度关联式。The fluidized bed dryer is one of the most important equipment for drying food particle. The minimum fluidization velocity is a key parameter for the design of the fluidized bed dryer. This paper introduced and discussed the research advance of four types of the basic equation deriving methods of the minimum fluidization velocities based on a critical analysis. The difference and relationship between of the basic equations, and simplification and extension of the each type methods were clarified. Three basic equations of the minimum fluidization velocity were recommended for fitting the correlations.
