A wide variety of pharmaceutical products, including pellets, granules, capsules, powders, and crystals are often coated. The procedure of coating tablets is a complex process that results in the forming of a thin layer around the tablet. This layer is in the range of 20 to 200 μm in thickness, or around 1 to 9% of the initial weight of the tablet.

Particle circulation and coating in a Wurster fluidized bed under different geometries
Abstract
The performance of particle coating is essentially determined by the morphology and uniformity of coating shells, which significantly depend on particle circulation. In this study, the geometry of a Wurster fluidized bed is changed by regulating particle circulation port size and nozzle…
