Romaco Innojet unveils the VENTILUS Lab fluid bed processor.
Designed for laboratory-scale applications, the VENTILUS Lab fluid bed processor from Romaco Innojet is used for granulating, drying and coating particles of any size from 10 µm to 2 mm. This multipurpose lab unit is intended for batch sizes from 0.7 to 7.0 liters. With its process air distribution system inside the cylindrical product container, the VENTILUS Lab shortens batch processing times by up to 25 percent because the required power can be used far more efficiently. The process air is introduced through the circular ORBITER booster, ensuring homogeneous flow conditions and extremely gentle intermixing of the batch. In combination with a central bottom spray nozzle, the ORBITER booster plate forms a unique functional unit enabling much simpler scale-up processes. When it comes to nozzle technology, users can choose between the tried-and-tested ROTOJET spray nozzle and the new FLEXIJET, which was specifically developed for granulation processes and is not only very easy to handle but also quick to clean.
The patented fluid bed components invented by Dr. h. c. Herbert Hüttlin lie behind the remarkably accurate application of the spray liquid with a precisely defined droplet size. With controlled release formulations, for instance, the modified release profiles are achieved using 10 to 15 percent less material. This targeted reduction in spray liquid usage also means less power consumption, so that the VENTILUS Lab results in substantially fewer carbon dioxide emissions from fluid bed processes. Furthermore, the rotating SEPAJET filter system minimizes general product loss by returning particles retained by the filter to the process rather than discharging them.
