【 摘 要 】

References(7)Cited-By(4)Spouted beds are often used for drying of coarse solid particles. In this study, the spherical porous solid particles of activated alumina were dried in three types of spouted beds with a draft-tube, an ordinary spouted bed, a screen-bottomed spouted bed and a top-sealed spouted bed, by using dry air at room temperature. Drying ability was defined as moisture evaporated per unit mass of solid particles per unit volume of air, being averaged during the time until moisture content reaches one-half of its initial value. The screen-bottomed spouted bed provided the highest drying ability and the ordinary spouted bed provided the lowest of all three spouted beds.
