Procedimiento

While the drum was rotating at about 6 rpm, the water was sprayed onto the solids at the rate of about 50 ml/min. Spraying was stopped after each 50 ml portion of water was added and the bed of semi-moisturized sodium tripolyphosphate was thoroughly mixed with a large spatula. When the desired amount of water had been added, water addition was stopped and the product was dried in the rotary drum at temperatures of 50°-70° C. by blowing hot air from a heat gun into the rotary. The temperature of the product being dried was measured by a stainless steel thermometer stem placed in the tumbling bed of product. Drying was conducted for about one hour and generally provided a sodium tripolyphosphate hexahydrate product having a free moisture content of less than about 1 weight percent and a total moisture content of between 18 and 22 weight percent.
