Abstract

Patente de Invenção: <B>"PROCESSO PARA PRODUZIR UMA COMPOSIçãO DETERGENTE DE DENSIDADE BAIXA ATRAVéS DO CONTROLE DA ALTURA DO ESGUICHO EM UM SECADOR DE LEITO FLUIDO"<D>. Um processo para preparar aglomerados de detergentes de densidades baixas que apresentam uma densidade em uma faixa de cerca de 300 g/I a cerca de 550 g/I é fornecido. O processo envolve as etapas de: (a) aglomerar uma pasta tensoativa de detergente ou um precursor seu e um material detergente inicial seco em um primeiro misturador de velocida'de elevada para obter aglomerados, (b) misturar os aglomerados em um segundo misturador de velocidade elevada para obter aglomerados armados e (c) fornecer os aglomerados armados a um secador de leito fluido no qual um aglutinante é pulverizado através de um esguicho que apresenta uma altura de cerca de 25 cm a cerca de 60 cm a partir da placa distribuidora do secador de leito fluido de tal modo que os aglomerados armados são secos e aglomerados para formarem os aglomerados de detergentes pequenos desejados.Invention Patent: <B> "PROCESS TO PRODUCE A LOW DENSITY DETERGENT COMPOSITION THROUGH THE FLUSH HEIGHT CONTROL IN A FLUID BED DRYER" <D>. A process for preparing low density detergent agglomerates having a density in the range of about 300 g / I to about 550 g / I is provided. The process involves the steps of: (a) agglomerating a detergent surfactant paste or a precursor thereof and an initial dry detergent material in a first high speed mixer to obtain agglomerates, (b) mixing the agglomerates in a second agitator high speed to obtain armed pellets and (c) supply the armed pellets to a fluid bed dryer in which a binder is sprayed through a nozzle that is about 25 cm to about 60 cm high from the dispenser plate fluid bed dryer such that the armed agglomerates are dried and agglomerated to form the desired small detergent agglomerates.
