Fluidized bed spray agglomeration – so that powders dissolve easily

First the definition: Fluid bed spray agglomeration is a shaping process for optimizing the properties of powders. Read here how the process works and what it brings you.

By spraying in the fluid bed system, we convert dusty, non-flowable and often poorly soluble particles: into free-flowing agglomerates or granules with excellent solubility. The process is particularly suitable as a precursor for tabletting and also for producing detergents, beverage powders and instant products.

How the fluid bed spray agglomeration process works

In fluid bed spray agglomeration, very small powder particles are moved in a fluidized bed and sprayed with a binder liquid.

The result: liquid bridges form between the particles and so-called agglomerates are created. What size is desired? The spraying process continues until the exact size is achieved. Typical sizes of the agglomerates range from 100 micrometers to 3 millimeters; the initial particles can be in microfine form.

Porous structure: Due to the low kinetic energy in the fluidized bed, we obtain porous structures with many internal capillaries, i.e. cavities, after evaporation of the residual moisture. The new structure is further strengthened by the hardened binder. The dust-free, flowable products can be easily metered and optimally processed.

Our fluid bed spray agglomeration – for your requirements

What are the specific requirements of your project? The parameters in the process are variable – for example, how the particle sizes are distributed, what bulk density or porosity is desired. So you can use our fluidized bed spray agglomeration to specifically create and enhance the good particle properties:

• porous with a large surface structure
• well wettable and optimally compressible
• very good solubility
