Abstract

A process for manufacturing particles of water-absorbing material is provided. The process includes providing a powder bed composed of an absorptive powder comprising a water-absorbing polysaccharide onto a surface; releasing an aqueous solution from a solution dispenser so as to contact the powder bed, thereby forming a solution-impregnated humid material; letting the solution-impregnated humid material agglomerate in substantially shear-less conditions to form an agglomerated humid material, the solution-impregnated humid material being supported by the surface; and drying the agglomerated humid material, thereby forming the particles.
