Coating is an integral part of pharmaceutical tablet and pellet production. Nevertheless, some problem areas have not been adequately solved so far, although they entail economic losses. To a certain extent, this is due to a presumed lack of viable solutions – but they do exist. A new generation of tablet coaters is addressing these challenges in an innovative way. When talking about challenges in coating, there are three areas involved: the quality of the coating result, the productivity of the coating process and the flexibility of the tablet coater.
Quality
Among the first things that come to mind when thinking about product quality is the prevention of defects. Preventing such defects is always a matter of stabilising the coating process by regularly checking parameters and adjusting them if necessary. The common method for increasing this process control is currently to improve the technical feedback and leave the interpretation and reaction to the operator.
