Claims (7)

  1. Procédé de préparation d'une composition détergente granulaire, comprenant les étapes suivantes:
    (i) on neutralise un ou des acides tensioactifs anioniques dans un excès de matière alcaline pour obtenir une pâte tensioactive qui comprend au moins 40 % en poids d'agent tensioactif anionique, ladite pâte ayant une viscosité d'au moins 10 Pa.s lorsqu'elle est mesurée à 70°C et à un taux de cisaillement de 25 s-1 de telle sorte que la pâte tensioactive reste pompable à des températures auxquelles l'agent tensioactif est stable;
    (ii) on conditionne ladite pâte; et ensuite
    (iii) on granule ladite pâte dans un mélangeur/granulateur à haut taux de cisaillement après mélange avec une poudre détergente sèche;
    caractérisé en ce que ladite étape de conditionnement (ii) est effectuée en ajoutant des structurants chimiques à ladite pâte, élevant de la sorte la viscosité apparente de ladite pâte,
    et caractérisé par ailleurs en ce que ladite pâte est maintenue à une température d'au moins 20°C, mais à l'exclusion de 20°C, tout au long de l'étape de granulation (iii).
  2. Procédé selon la revendication 1, dans lequel ledit structurant chimique est sélectionné dans le groupe comprenant l'hydroxyde de sodium en solution aqueuse, l'hydroxyde de potassium en solution aqueuse, le chlorure de sodium, les phosphonates, les silicates, la silice, l'amidon, des polymères et des copolymères, des agents tensioactifs non ioniques, l'urée et leurs mélanges.
  3. Procédé selon l'une quelconque des revendications 1 et 2, caractérisé en ce que ledit structurant chimique se présente sous la forme de poudre et est sélectionné dans le groupe comprenant les phosphonates, les silicates, la silice, les copolymères d'acide maléique et d'acide acrylique.
  4. Procédé selon l'une quelconque des revendications 2 et 3, caractérisé en ce que ladite étape de conditionnement est réalisée au moyen d'une extrudeuse, ladite extrudeuse ayant un ou plusieurs orifices d'entrée dans le cylindre de l'extrudeuse pour permettre l'addition de poudres et/ou de pâtes supplémentaires qui sont mélangées dans l'extrudeuse.
  5. Procédé selon la revendication 4, caractérisé en ce que la pâte pénètre dans l'orifice d'entrée de l'extrudeuse à une température comprise entre 40 et 80°C et sous un vide de 0 à 7,3 kPa en dessous de la pression atmosphérique.
  6. Procédé selon l'une quelconque des revendications 4 et 5, caractérisé en ce que le cylindre de la section de mélange de l'extrudeuse est refroidi par n'importe quels moyens appropriés, notamment par addition d'une quantité allant jusqu'à 30 %, en poids de la pâte, d'anhydride carbonique solide ou d'azote liquide directement dans le cylindre de l'extrudeuse, pourvu que ladite pâte soit maintenue à une température entre 20 et 90°C, mais à l'exclusion de 20°C, tout au long de l'étape de granulation (iii).
  7. Procédé selon l'une quelconque des revendications 4 à 6, caractérisé en ce que l'extrudeuse est une extrudeuse à vis jumelées.
