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.

Tablet coating in lab-scale drum coaters: Combining DEM simulations and spray experiments to predict…
In pharmaceutical industry the coating of granulates or tablets is an essential production step, which is often realised in a rotating drum moving the tablet bed and a number of spray nozzles installed above this bed. The nozzles atomise the coating liquid through a high-velocity annular air-stream…
