Fluid bed
A particle in a closed system can behave like a fluid.Among various microencapsulation techniques, a fluidized bed is a versatile method for encapsulating molecules. It exploits the physical phenomenon according to which a solid particle behaves like a fluid under specific physicochemical conditions.
This technology helps achieve a quick and uniform result, using air to coat and dry the substrate simultaneously. This allows drying, depositing functionalizing coatings, and forming new particles through the granulation or agglomeration of fine powders to improve their performance and solubility.
In house: Mini-Glatt fluid bed.
Fluid bed schematic diagram: 1. Process air inlet, 2. Coating chamber, 3. Expansion chamber, 4. Filters system, 5. Air outlet, 6. Pulse air, in the right part is represented the machine design referred to the nozzle position: A. bottom/wuster spray, B. top spray and C. tangential spray.
