With coaters from the LC and LC light series, Lödige Process Technology offers two different machine concepts for the film coating of tablets. Pharmaceutical companies have a choice when looking for the optimum task-specific solution. Systems can thus be realised that precisely meet the respective requirements.
Film coating is a standard processes in the pharmaceutical industry. During this process, tablets are coated in a fully perforated drum using the direct current method. The process is divided into three parts: spraying the paint, drying it and mixing the tablets.
Drum coating for efficient coating
Lödige offers various drum coaters. All ensure an efficient coating process. This is because a large number of variables come into play during the coating process, which have a significant impact on the quality of the result and must be set up accordingly.
How do users find the perfect machine? This checklist can help:
- Are different product forms (such as tablets, capsules or pellets) to be coated?
- Is the coating process to take place in a potentially explosive atmosphere?
- Are there any special containment requirements to be met?
- Are there any other special features?
The more questions are answered with “yes” for the specific application, the more individual the system solution might have to be. Lödige has the necessary industry experience to adapt systems precisely to customer requirements and all process conditions.
For challenging coating tasks
The film coaters from the LC series are the solution for challenging applications in the coating of tablets. They can also be used for dosage forms such as capsules, pellets and dragées, just like normal film-coated tablets, and already offer a wide usable volume of 20 to 100 per cent for batch sizes from 0.45 to over 1 tonne without modification of the system. However, the series also offers a high degree of flexibility beyond throughput – for example for high-containment requirements, to which the entire process can be easily adapted. This ensures that employees and the environment are safely protected. Explosion-proof versions with ATEX certification and special designs such as nitrogen circulation systems are also possible. Users who place high demands on the energy efficiency of their production benefit from options such as a heat exchanger for heat recovery.
Consistently developed and optimised over thirty years, the series now not only offers a high level of ease of operation and cleaning, but also intelligent process technology with processes that are up to 40 percent faster than other systems.
Alternative for standard applications
For many applications, however, such a degree of specialisation is unnecessary. For example, if all the questions on the above checklist were answered with “no”. Lödige has designed the LC light series for applications with low customisation requirements. With its standardised design, the completely newly developed product family offers an attractively priced alternative to customised machines.
The performance and scope of the series prove that a standard can meet high demands: Available in three sizes and equipped with clearly defined but comprehensive functions, the machines offer an efficient solution for both aqueous and organic coating processes. The coaters are insulated all around and offer fully automatic production with integrated recipe management.
The liquid addition with Manifold system, the determination of the spray rates with a mass flow meter and the swivelling nozzle arm of the coater all indicate the high level of quality. A Washing-in-Place (WIP) system is standard on every model in the LC light series. The available options cover the most common coating requirements like individual air technology modules, an ATEX version and qualification documentation.
Users of the LC light series machines not only benefit from the approximately 40 percent lower investment costs but also from a significantly shorter delivery time.
