This works are very disadvantageous because these dusts in the most common cases are classified as harmful to health. Furthermore, there is with decreasing particle size increases in tendency to Dust explosions.

Zusammenfassend läßt sich folgendes feststellen:In summary, the following can be stated:

Die Erfindung betrifft ein Verfahren zur Herstellung von Vollwaschmitteln und Vollwaschmittelkomponenten in Granulat- oder Agglomeratform auf Trockenstoffbasis in einer im wesentlichen horizontal ausgerichteten Wirbelschicht.The invention relates to a process for the preparation of heavy-duty detergents and heavy duty detergent components in granular or agglomerate form on a dry basis in a substantially horizontally oriented fluidized bed.

Die Aufgabe der Erfindung besteht darin, Waschmittelgranulate oder -agglomerate herzustellen, die sich durch eine homogene Zusammensetzung der aus den einzelnen Rohstoffkomponenten inklusive dem Bindemittel und der Feuchtigkeit auszeichnen, eine hohe Festigkeit gegenüber mechanischer Beanspruchung aufweisen, gut in Wasser dispergierbar und staubarm bis nahezu staubfrei sind.The object of the invention is to detergent granules or to produce agglomerates characterized by a homogeneous composition from the individual raw material components including the Binders and moisture are characterized by high strength have mechanical stress, good in water dispersible and low in dust to almost dust-free.

Erfindungsgemäß wird das dadurch erreicht, daß die Herstellung des Produktes in einer Wirbelschicht erfolgt. Dabei wird dem Feststoff in der Wirbelschicht über ein Bedüsungssystem ein Bindemittel und/oder Komponenten in Form von Lösungen, Suspensionen oder Schmelzen zugeführt. Durch die über die Prozeßluft eingebrachte Energie erfolgt eine Trocknung und Verfestigung der sich im Bedüsungsbereich der Wirbelschicht bildenden Agglomerate/Granulate. Dabei liegt die Zuführungstemperatur der Prozeßluft zwischen 20 °C bis zur Zersetzungstemperatur der beteiligten Stoffe. Durch Einstellung der Trocknungstemperatur kann die Produktfeuchte variiert werden. Die durch die Prozeßluft aus der Wirbelschicht mitgerissenen Partikel werden in einer im Wirbelschichtapparat integrierten mit Querschnittserweiterungen versehenen Expansionszone und in einem daran anschließenden Filtersystem von der Luft getrennt und in das Wirbelschichtbett zurückgeführt und dort agglomeriert. Damit entsteht ein staubarmes bzw. staubfreies Produkt mit einem Körnungsbereich von 0,2 bis 2,00 mm.According to the invention this is achieved in that the production of the Product takes place in a fluidized bed. This is the solid in the fluidized bed via a Bedüsungssystem a binder and / or components in the form of solutions, suspensions or Melting supplied. By introduced via the process air Energy is a drying and solidification in the Bedüsungsbereich the fluidized bed forming agglomerates / granules. In this case, the feed temperature of the process air is in between 20 ° C to the decomposition temperature of the substances involved. By Setting the drying temperature, the product moisture can be varied become. The entrained by the process air from the fluidized bed Particles are integrated in a fluidized bed apparatus Cross-sectional extensions provided expansion zone and in one subsequent filter system separated from the air and into the Fluidized bed returned and agglomerated there. This creates a dust-free or dust-free product with a grit area from 0.2 to 2.00 mm.
