摘要： Low phosphate, light density, laundry detergent powder compositions, comprising an agglomerated mixture of expanded borax of bulk density of approximately 12 to 20 pounds per cubic foot as a carrier, additional builders, other adjuvants and organic liquid surfactants, such detergent compositions being produced by an economical cold spray-mix process under controlled and relatively anhydrous conditions. The weight percent of expanded borax of low bulk density is about 10% to 80%, preferably about 15% to 35%, and the weight percent of the organic liquid surfactant is 5% to 25%, typically 13% to 18%, of the detergent powder product. The phosphate content of the composition is not more than 5% based on P.sub.2 O.sub.5.

摘要： A rotary inclined tubular drier for puffing or expanding borax and a process for the production of puffed or expanded borax beads of desired physical characteristics. A rotatable tube is mounted on bearing wheels and surrounded by a fixed, close-fitting, insulated tube having electrical heating elements running lengthwise attached to its inside wall. The rotatable tube is fed continuously with granular borax feedstock by a vibratory feeder from its higher end and the puffed borax is discharged into a discharge chute from the lower end of the tube. A counter current of dry air is maintained by a suction hood at the high end of the tube, and borax is prevented from adhering to the interior of the tube by an adjustable, spring-loaded, internal scraper. The temperature of the drier is controlled by means of a pyrometer incorporated into a scraper support rod on the interior of the tube. Puffed borax beads of particularly desirable characteristics for detergent use are produced from sodium tetraborate pentahydrate by heating the drier to 220.degree.-450.degree. F and adjusting the angle of incline and rate of rotation so as to provide a 45-90 second residence time in the drier for the borax.
