ABSTRACT:
Manufacturing dry, free-flowing crystalline sodium carbonate peroxide by passing a gas stream at a temperature between 70.degree. and 150.degree. C into a drying zone containing moist sodium carbonate peroxide while maintaining the exit gas stream temperature between 50.degree. and 130.degree. C until the sodium carbonate contains between 0.05% and 0.5% by weight moisture, immediately passing the dried material into a cooling zone where the sodium carbonate peroxide temperature is lowered to between 0.degree. and 40.degree. C, and removing a dry, free-flowing, crystalline sodium carbonate peroxide product containing between 0.001% and 0.20% by weight moisture.
