Granulation and tabletization of pharmaceutical lactose granules prepared by a top-sprayed fluidized bed granulator

Material properties of partially pregelatinized cassava starch prepared by mechanical activation

“…The floodability shows stability or instability of a powder and so the ease with which it flows under strain. The floodability of powder is obtained from angle of difference and dispersibility, and the higher values of angle of difference and dispersibility, the greater flushing tendency in the behavior of the powder [32,37]. Particles with sufficiently high flowability and floodability would be easy to handle, resulting in uniform bulk properties.…”

Application of Wet Granulation Processes for Granola Breakfast Cereal Production

“…Charinpanitkul et al [20] reported the influence of fluidising air velocity, atomising air temperature, atomising air pressure and types of raw materials on granule physical properties. They found that the granules prepared at the lower fluidising air velocity had larger average particle size.…”

Utilization of rice-husk packed beds as fine dust collectors at heavy dust loadings

“…The time-dependent indepth filtration phenomenon was too complicated for the Ergun equation to predict the temporal change in the pressure drop [10,11]. Prediction of the temporal change in filtration efficiency also ran into the same difficulty.…”

“…Prediction of the temporal change in filtration efficiency also ran into the same difficulty. Therefore, the Ergun equation and the available filtration efficiency correlations could only be used to predict their initial values when the filter media was still relatively clean [10][11][12][13][14][15]18]. In fact, unless some complicating phenomenon intervenes, both the pressure drop and collection efficiency of pure in-depth filtration should rise almost exponentially.…”

“…Though the pressure drop across a packed bed could often be reasonably predicted by the well-known Ergun equation, this correlation would not be suitable for packed particles with broad size distribution and/or irregular morphology [9]. The key limitation and parameters of the Ergun equation and the dust collection efficiency of a packed bed have been investigated theoretically and experimentally [5, [10][11][12]. To understand the fine dust filtration phenomena, a systematic consideration of the various particle deposition mechanisms such as interception, inertial impaction, diffusion, gravitational settling, and electrostatic, would also be indispensable [10][11][12][13][14][15].…”
