Experimental study and optimization of the agglomeration of acerola powder in a conical fluid bed

The aim of this work was to study the physical property modifications of acerola powder produced by a wet-agglomeration process in a fluid bed. A 22 full experimental design was used to evaluate the influence of the main operational conditions and to optimize the agglomeration process. The product transformations were determined by an analysis of the particle diameter, size distribution, morphology, moisture content and solubility. The agglomeration of small granules results in an increase in the instant properties, increasing particle solubility.
