STE TECPHARM offers all range of services: installation “turnkey concept” in the 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.
