With the aim of improving process and tablet quality in film coating, Lödige Process Technology introduced a technical solution by which the air and thus heat energy is evenly distributed over the tablet bed. The air in the Lödige coater flows in via a distributor pipe and circulates around the drum of the coater. The air thereby enters the drum over an enlarged area, ensuring a very even, almost turbulence-free airflow inside the coater especially in the nozzle zone to guarantee optimum coating results. Thermal imaging cameras were systematically used in the development of the process – the first time in this area of application.
