Detergent slurry process
Abstract
Abstract A METHOD HAS BEEN FOUND FOR INCREASING THE ALKALI METAL SILICATE CONTENT OF SPRAY DRIED DETERGENTS WITHOUT DECREASING THE SPRAY DRYER PRODUCTION AND WITHOUT CHANGING THE SOLUBILITY CHARACTERISTICS OF THE DETERGENT. THE METHOD INVOLVES THE PREPARATION OF DETERGENT SLURRIES IN A CRUTCHER WITH HIGH ALKALI METAL SILICATE CONTENT BY ADDING ALKALI METAL SILICATE GLASS TO THE SLURRIES IN SUCH A MANNER THAT IT READILY DISSOLVES. THE GLASS IS ADDED THROUGH A JET NOZZLE WITH STEAM PRESSURE. THUS, THE AMOUNT OF WATER THAT MUST BE REMOVED BY SPRAY DRYING CAN BE REDUCED OR REMAIN UNCHANGED WHILE THE SILICATE SOLIDS OF THE SLURRY AND SUBSEQUENTLY THE DETERGENT CAN BE INCREASED SUBSTANTIALLY.
