Abstract
A method of producing granular sodium dichloroisocyanurate, comprises the steps of forming thin columnar pellets of sodium dichloroisocyanurate from wet powdery solids thereof obtained in the manufacturing process, drying the pellets to remove free water therein, compacting, crushing and screening. According to this method, granular sodium dichloroisocyanurate in the form of anhydride, monohydrate or dihydrate may be obtained by controlling the temperature and the humidity of heating air used in the drying step.
Claims10
A method of producing granular sodium dichloroisocyanurate comprising the steps of extruding wet sodium dichloroisocyanurate having a moisture content of about 15-30% through a screen with a plurality of openings to form columnar pellets, passing said pellets through a fluidized bed heating chamber to dry said pellets until they contain substantially no free water, compacting said dried pellets to increase their bulk density, crushing said compacted pellets, and screening the crushed pellets to obtain the granular sodium dichloroisocyanurate product.
