Title (DE) VERFAHREN ZUR HERSTELLUNG VON GRANULAREN WASCH- ODER REINIGUNGSMITTELN ODER KOMPONENTEN HIERFÜR
(EN) PROCESS FOR THE PRODUCTION OF GRANULES OF WASHING AND CLEANING AGENTS OR COMPONENTS THEREFOR
(FR) PROCEDE DE PREPARATION DE DETERGENTS ET DE NETTOYANTS GRANULAIRES OU CONSTITUANTS UTILISES POUR LES PREPARER
Abstract:
(DE) Es sollte ein Verfahren für das Verpressen von festen rieselfähigen Vorgemischen bereitgestellt werden, das es erlaubt, unter schonenderen Bedingungen als üblich zu verfahren. Dies wurde dadurch erreicht, daß die Lochformen, durch die verpreßt wird, in zwei gegeneinanderlaufenden und ineinandergreifenden Zahnrad-Preßwalzen angeordnet sind. Gegebenenfalls auftretende Grobkornanteile können ohne Vermahlung rückgeführt werden.
(EN) The invention relates to a process for pressing solid, pourables mixtures which is carried out under more gentle conditions than usual in that the holes through which pressing takes place are arranged in two meshing counter-rotating gear-wheel press rolls. If necessary, coarse grain portions can be returned without crushing.
(FR) L'invention concerne un procédé permettant de comprimer des prémix solides coulants, selon lequel le processus peut se dérouler dans des conditions impliquant moins de risques d'altération des produits, comparativement aux procédés similaires classiques. A cette fin, les moules perforés à travers lesquels les prémix sont comprimés, sont disposés dans deux rouleaux de compression à roues dentées tournant en sens contraire et en prise. D'éventuelles fractions à gros grains peuvent le cas échéant être renvoyées sans broyage.
