LABORATORY FLUIDIZED BED DRYER
WET GRANULATE DRYING BY FLUIDIZATION | LAB SCALE
Lab Scale Fluidized Bed Dryer designed for 3 different laboratory processes:
■ Drying of wet granulate.
■ Top drive granulation.
■ Bottom spray coating for micro granules.
Innovative high-quality equipment certified by accredited entities.
Fully designed and built in Europe following regulatory requirements and GMP´s normative.
Used for new product development, with a technology that easily allows changing to pilot scale. And also provides useful information for industrial batches.
It disposes of 2 interchangeable recipients: 4,5 L and 9 L capacity.
The Laboratory Fluidized Bed Dryer allows setting up specific drying programs for each product, which are executed from the operator touch panel, through necessary commands and controllers, achieving that in the process development and program set-up we can eliminate characteristic problems, such as:
■ Formation of air channels.
■ Lack of uniformity in the drying process.
■ Localized overheating of the granulation.
■ Attrition of the granulation as it dries.
More and more it is important to optimize processes before industrialization. Obviously to minimize risks in time and cost. In STE we have a pilot plant for testing purposes with all equipment on a pilot scale. This facility allows the client to do a complete scaling-up for each process.
STE TECPHARM offers all range of services such as installation, integration in client facilities, start-up, qualification, training, and production support
The fluidization process is used extensively in the pharmaceutical industry to reduce the moisture content of powder and granules in a drying process.
In this process, hot air is introduced at defined pressure and flow rate through a perforated bed of moist solid particles. The wet solids are lifted from the bottom and suspended in a stream of air (fluidized state).
Heat transfer is accomplished by direct contact between the wetted solid and hot gases.
The vaporized liquid is carried away by the drying gasses.
