Abstract
(DE)
Die Erfindung betrifft ein Verfahren zur Herstellung von Granulaten, insbesondere tensidhaltigen Granulaten, aus einem feuchten Ausgangsmaterial in einem luftdurchströmten Trockner (1), wobei das im Trockner (1) gebildete Granulat über eine vom Trockner (1) fortweisend geneigte Ausgabevorrichtung (2) auf eine Fördervorrichtung (3) ausgegeben wird. Um ein einfach und kostengünstig zu betreibendes Verfahren zu schaffen, bei dem die Aufgranulation von Grobanteilen vermieden wird, wird vorgeschlagen, dass die Verweilzeit des Ausgangsmaterials im Trockner (1) über die Laufgeschwindigkeit der Fördervorrichtung (3) gesteuert wird. Weiterhin betrifft die Erfindung eine Vorrichtung zur Durchführung des Verfahrens.
(EN)
The invention relates to a method for producing granulates, notably granulates containing surface-active agents, from a moist starting material in an air-swept dryer (1). According to said method the granulate formed in the dryer (1) is delivered to a conveyor device (3) via an inclined discharge unit (2) pointing away from the dryer (1). To create an easy and economical method which avoids the production of excessively large granules caused by the granulation of coarse-particle components, the invention provides for the dwell time of the starting material in the dryer (1) to be controlled via the travel speed of the conveyor device (3). The invention also relates to a device for carrying out the above method.
(FR)
L'invention concerne un procédé pour produire des granulés, notamment des granulés tensioactifs, à partir d'un matériau de départ humide, dans un séchoir (1) parcouru par un courant d'air. La granulé formé dans le séchoir (1) est évacué par l'intermédiaire d'un dispositif d'évacuation (2) incliné, s'éloignant du séchoir (1), qui le dépose sur un dispositif transporteur (3). L'invention vise à créer un procédé pouvant être mis en oeuvre de façon simple et économique, et évitant la formation de granulés de taille excessive par accumulation de fractions grossières. A cet effet, le temps de séjour du matériau de départ dans le séchoir (1) est régulé par l'intermédiaire de la vitesse de défilement du dispositif transporteur (3). L'invention concerne en outre un dispositif pour mettre en oeuvre ledit procédé.
