Abstract

LA INVENCION SE REFIERE A UN PROCESO Y A UN DISPOSITIVO DE GRANULACION EN LOS QUE UNOS CEBOS PARA HACER ENGORDAR SON LLEVADOS SOBRE UN LECHO FLUIDIZADO INCLINADO (POR) () Y DESPUES CAEN EN UNA CUBETA DE DONDE SON PROYECTADOS EN DIRECCION DE UNA BARRERA (11, 12). DE AHI LOS CEBOS VUELVEN A CAER SOBRE EL LECHO TRAS HABER RECIBIDO UNA PULVERIZACION DE UNA SUSTANCIA QUE LOS HACE ENGORDAR, Y ASI SUCESIVAMENTE. CUANDO LOS GRANULADOS FORMADOS A PARTIR DE LOS CEBOS ALCANZAN UN TAMAÑO APROPIADO, SE LES HACE PASAR POR ENCIMA DE LA BARRERA DURANTE LA OPERACION DE PROYECCION Y SON RECOGIDOS EN UNA TOLVA (7).
