The compression characteristics of consolidated deposits formed in centrifugal flotation of O/W emulsion were clarified with the aid of an analytical centrifuge which could monitor timed near-infrared (NIR) transmission profiles of samples in the centrifugal field. Compression data of the soft particles were then compared with those of the rigid particles of silicon dioxide in centrifugal sedimentation. The dependence of the local porosity on the local solid compressive pressure was determined based on the relation between the average porosity and the solid compressive pressure at the bottom of the consolidated deposit obtained from experiments conducted tinder various angular velocities, sample heights, and concentrations of the dispersed phase. Moreover, variations in the local porosity and the local solid compressive pressure across the consolidated deposit were evaluated from the relation between the local porosity and the local solid compressive pressure. The analysis revealed that the consolidated creaming layer of the soft particles is of much lower porosity than the consolidated sediment of the hard particles. while the solid compressive pressure is much smaller. Also, depending on conditions, the greater part of the consolidated creaming layer of oil droplets exhibited lower porosity than hexagonal close-packed undistorted spheres, because of the deformation of the oil droplets under the action of the solid compressive pressure.
