Fluid bed processor / agglomeration

Agglomeration optimizes product attributes.

In the agglomeration process, fine powder particles are swirled around in the fluidized bed and stuck together with a sprayed liquid to form larger particles. This process is now used more and more often for modifying the properties of powders and making bulk products easier to handle. Important product attributes like porosity, bulk density and the proportion of dust can be adjusted precisely by agglomeration. A further benefit is achieved if ingredients such as vitamins are applied with the sprayed liquid.

How you benefit by agglomeration

Better solubility

The enlarged, low-dust powder agglomerates produced by fluid bed drying are much easier to dissolve and dose than the original product.

Optimal distribution of the ingredients

The homogeneous distribution of the individual components of all the starting materials in the “blackberry” structures produced by agglomeration prevents their subsequent separation and thus ensures maximum reliability and safety of the process.

Easier handling

Agglomeration in the fluid bed processor results in free-flowing, readily dispersible particle structures with a low proportion of fine dust. This greatly improves the hygiene situation in downstream producing companies. Moreover, handling is simplified by the good tabletting properties of the agglomerates.
