The LC series from Lödige was specially developed for coating tablets. The top priority in the conception was optimum process management in addition to ease of operation and ease of cleaning. All three sub-processes, which are relevant for film coating, were optimised: spraying the finish, mixing the tablets and drying them.
At the same time, this development distinguishes itself with a special design for spraying on the finish with a low number of jets, which enables a perfect fit with the tablet bed. The technology makes it possible to easily set and automatically control the correct spraying distance and angle at any time, in order to achieve a perfect result. At the same time, the optimum arrangement and number of jets accelerates the process in comparison to comparable coaters.
A recently for a major German pharmceutical manufacturer commissioned LC 150 coating system with a useable volume of 750 l requires a very complex materials preparation technology, especially after a large amount of drying gas is used. In addition, the system is equipped with a high pressure jet assembly. This ensures short processing times as well as superior coating homogeneity of the tablets. To guard against explosions, the entire process takes place in a nitrogen circulation system.
