Abstract

A process for obtaining grain sodium perborate having a grain dimension of between 100 and 850 microns and a bulk density of between 0.35 and 0.45 g/cm3 from a supersaturated solution of sodium perborate, characterized by introducing on the surface of said solution a liquid or solid refrigerating agent, slowly shake the dough by means of a movement that limits the vertical displacements of the liquid and then, once the desired grains have formed, they descend, thickening, filtering and drying the grains.
