PURPOSE: To reduce the amt., i.e., the yield, of the fine powder generated when a granular article is dried by crushing the article to a specified grain size distribution. CONSTITUTION: Sodium bicarbonate is crushed, the crushed material is humidified and kneaded with sodium chloride, the humidified and kneaded article is granulated, and the granulated article is dried and formed into a granule. In the granulating stage, sodium bicarbonate is crushed to 20-50μm grain size distribution (D90 ) and granulated. A product granule is produced in this way with <=5% powder yield.
