Hey Mustafa, maybe your Drying Temp is not appropriate according to core tablet. I think this is problem related to high temperature flux for shorter duration of time on core tablet. This will lead to uneven drying of coating film on tablet, resulting in rough surface on tablet. You can try to troubleshoot this by reducing inlet temperature and modifying solvent ratio, so that drying will be even and surface will get shiny appearance.
