Jeff Raabe 7451 Empire Drive Suite A Florence, KY 41042 859-594-3640 JeffRaabe@lodige-pt.com www.lodige-pt.com Coating in a Lödige Coater LC Coater type LC developed by Lödige can be used for processing different shapes of tablets, capsules and pel- lets and is suitable for film and sugar coating without extensive conversion work. The coater operates on the co-current, under-pressure principle. 25 – 100 % of the working capacity of the Coater can be used without modification of the system. As well as the Coater itself, the LC Coating System includes the inlet air treat- ment, the exhaust air system, the controls, liquid dosing, feeding and discharging and the WIP system. Optimal process control, fast coat- ing speed, easy handling and easy cleaning were the top-priority for development of the Coater. The coating process can be divided into the following three sub-processes: spraying of lacquer, drying of the tablets and mixing of the tablets. The LC coater series optimizes all three sub-processes. The totally perforated drum with a free surface of more than 40 % enables a maximum air flow. The mixing elements ensure the uniform and gentle mixing, even with variable filling degrees. These are the most important conditions for best uniformity of coating. The optimized nozzle arm permits easy adjustment of the nozzle position to the tablet bed – making it possible to set the optimum spraying distance and angle at all times. The heated inlet air is guided into the Coater housing via a special distribution sys- tem and led through the perforation into the coating drum, thereby ensur- ing quick drying of the moist tablet surfaces. The air is then extracted through the tablet bed.
