Error Method

The purpose of this research was to study the aqueous-based film coating of tablets utilizing a laboratory-scale side-vented perforated pan-coating apparatus. The process parameters of potential importance with respect to the final film quality were evaluated by using trial and error method. Tablets were evaluated for coating uniformity (mg), coating process efficiency (%), surface roughness, and %LOD (loss on drying). Spray rate and inlet air temperature both affect the all characteristic of coated tablets. Rotating speed of pan mainly affect the coating uniformity of tablets. % Solid content affects the surface of coated tablets and also creates a problem in spray flow. The process parameters relevant to a side-vented perforated pan coating process can be identified and, consequently, optimized.

Blade Coating

A blade coating process for non-Newtonian liquids is presented using different air pressure applied at the inlet and the exit of the coating gap. The system consists of a coating blade to form a gap and a vacuum box to create different air pressures to permit coating a thin liquid film on an advancing plastic web. The solution consists of matching the boundary conditions of each subregion of the coating process. The calculated liquid film thickness as a function of the coating gap and applied air pressure difference agrees closely with experimental data obtained on a laboratory coating device.
