摘要
A process is described in which granular calcium hypochlorite particles are encapsulated with at least one layer of a hydrated low melting inorganic salt. In this process granular calcium hypochlorite particles are lifted from a moving bed to the upper part of a distribution zone and the lifted particles are released to fall downwardly through the upper portion to the moving bed. A molten hydrated low melting inorganic salt is sprayed onto the falling particles above the moving bed, and the coated particles are cooled to provide at least one solid outer layer of said low melting hydrated inorganic salt.
