Abstract

L'INVENTION CONCERNE DES FERTILISANTS GRANULAIRES REVETUS OU ENROBES D'UNE COUCHE ENROBANTE DONT LA PERMEABILITE A L'HUMIDITE EST SOUS DEPENDANCE CONTROLEE DE LA TEMPERATURE. LA METHODE DE PRODUCTION DES FERTILISANTS COMPORTE L'INJECTION D'AIR CHAUD SECHANT DANS UNE COLONNE 1 A L'AIDE D'UN VENTILATEUR 9 PAR UN ECHANGEUR DE CHALEUR 7 TANDIS QU'UN JET DE FERTILISANT GRANULAIRE EST INTRODUIT EN 3 DANS LA COLONNE 1. EGALEMENT ON VAPORISE PAR UNE BUSE 2 UNE SOLUTION CHAUDE D'UNE RESINE DE TYPE POLYOLEFINE, D'UN COPOLYMERE ETHYLENE-ACETATE DE VINYLE OU D'UNE RESINE DU TYPE VINYLIDENE SUR LESDITS GRANULES DE FERTILISANTS. ON OBTIENT LE SECHAGE DESDITS GRANULES DE FERTILISANTS LORS DE LA VAPORISATION PAR LA SOLUTION QUI A LA PROPRIETE DE FORMER UNE SOLUTION QUAND ELLE EST CHAUDE MAIS DE SE TRANSFORMER EN UNE GELEE QUAND ELLE EST REFROIDIE. EN OUTRE, UNE FINE POUDRE UNIFORMEMENT DISPERSEE EST INCORPOREE DANS L'AIR SECHANT PRECITE OU DANS LA SOLUTION PRECITEE DE MANIERE A OBTENIR UNE COUCHE ENROBANTE DE LADITE RESINE CONTENANT UNE POUDRE FINE UNIFORMEMENT DISTRIBUEE. LES FERTILISANTS AINSI OBTENUS PEUVENT ETRE EMPLOYES COMME ENGRAIS EN AGRICULTURE.
