ABSTRACT:
Method and apparatus for producing sodium perborate monohydrate by dehydrating sodium perborate tetrahydrate in a fluid bed with heated air. Contact surfaces are arranged inside the fluid bed whose total area is the same as up to 500 times the area of the approach-flow bottom of the fluid bed. The contact surfaces are advantageously designed as heat exchangers whose surface temperature is adjusted to maintain 90.degree. to 110.degree. C. at the contact surfaces. The method results in a sodium perborate monohydrate with especially high abrasion resistance. In addition, the energy requirement is lower than that provided in the previously known method commonly used in the industry.
