Abstract: Fluidized-bed coating of peroxy compounds, especially sodium percarbonate for use in detergent and bleaching products. Production of coated peroxy compounds by fluidized-bed coating comprises spraying an aqueous coating solution onto particles of the peroxy compound in a fluidized-bed chamber and drying the coating by means of a fluidizing gas injected through a radial distributor plate at a fluidized bed temperature of 30-70 degrees C, where the fluidizing gas emerges (upwards) from openings in the distributor plate at an angle of less than 35 degrees to the horizontal and the coating solution emerges (downwards) from spray nozzles at the same angle.
