Manufacturing process for sodium perborate monohydrate and product obtained according to the process

摘要

Abrasion resistant granules of sodium perborate monohydrate are made by introducing an aqueous solution containing hydrogen peroxide and an aqueous solution containing sodium metaborate simultaneously into a fluidized bed dryer which contains seeds of a size smaller than that of the desired granules. Water present in the aqueous solutions is evaporated by fluidization gas which is introduced into the fluidized bed dryer. The process products, in one stage, granules of sodium perborate monohydrate having good flavorability, abrasion resistance, and other desirable properties.
