Gebrüder Lödige
The new Lödige LC is a highly efficient tablet coater at an attractive price. It provides:
• a 20% reduction in costs owing to development of essential machine parts
• a 30–100 % filling degree through optimised drum geometry and optimised mixing elements
• and a 40% increase in speed thanks to high-performance air technology, nozzle distances and number of nozzles.
Optimal process control, easy handling and easy cleaning were the top-priority criteria for development of the coater. The coating process can be divided into three sub-processes — spraying of lacquer, drying of the tablets and mixing of the tablets.
The LC coater series optimises all three sub-processes. The totally perforated drum, with a free surface of more than 40%, allows a high air flow. The mixing elements ensure the uniform and gentle mixing, even with variable filling degrees between 30% and 100%, which is the most important condition for achieving best uniformity of coating. The optimised nozzle arm guarantees the perfect adjustment to the tablet bed, therefore it is always possible to set the best spraying distance and angle. Directly under the spraying zone, the heated inlet air is led to the tablet bed and ensures the quick drying of the wet surfaces. The air exhausts through the tablet bed.
Due to work safety reasons, the whole product inside the coater is kept below atmospheric pressure. Complete discharge is still guaranteed without any additional equipment and the required discharge time has even been reduced.
A new solution has been found for the cleaning process. An integrated ultrasonic generator reduces the necessary cleaning time considerably, especially in cases of hardly soluble substances.
The coater is intended for through-the-wall assembly and therefore provides optimal separation between process area and technical area. Furthermore, it is always accessible by the maintenance staff.
Last but not least, the new control system is very easy to operate and fulfills all the latest GMP requirements.
The Lödige LC will be displayed at POWTECH 2013, 23–25 April, Nuremberg, Germany, Hall 5, Stand 222.
