Gas-solid fluidized-bed systems offer great advantages in terms of chemical reaction
efficiency and temperature control where other chemical reactor designs fall short. For this …

Air-suspension particle coating has been slow to develop in the food industry. This is not
surprising considering the economic constraints for low cost ingredients and low cost …

Abstract A coupled CFD-DEM and Monte Carlo approach was developed to investigate
coating properties in a Wurster fluidized bed by considering gas flow, particle motion, droplet …

A review of different approaches to modeling the coating mass uniformity in fluidized bed
and rotating drum (pans) equipment is presented. In order to predict the coefficient of …

Abstract Cycle Time Distribution (CTD) plays a critical role for determining uniformity of
particle coating in spray fluidized beds. However, the CTD is influenced by both geometrical …

Coating of tablets is a common unit operation in the pharmaceutical industry. In most cases,
the final product must meet strict quality requirements; to meet them, a detailed …

Fluidized bed dryers (FBD) are commonly employed in many industries to dry particulate
solids. FBDs provide good solids mixing, high rates of heat and mass transfer, and relative …

This paper investigates inter-tablet coating variability, specifically, the variability of tablet
residence times within the spray zone of a horizontal coating pan. Results from experiments …

Abstract A CFD–DEM coupled with a cohesive contact model is developed for simulation of
a Wurster fluidized bed with heat and mass transfer. First, the water evaporation and …

The ability to coat particles with a uniform film of a desired thickness is a key requirement in
many industries such as pharmaceuticals, food processing and chemical manufacture …
