Abstract
LA INVENCION FACILITA UN APARATO PARA RECUBRIR ELECTROSTATICAMENTE EL NUCLEO DE UNA TABLETA FARMACEUTICA CON UN MATERIAL DE RECUBRIMIENTO EN POLVO. EL APARATO COMPRENDE UN PRIMER TAMBOR GIRATORIO (12) EN EL CUAL SE MANTIENE EL NUCLEO AISLADO ELECTRICAMENTE DE SU CONTORNO, PERO CON UNA DIFERENCIA DE POTENCIAL CON TIERRA POR MEDIO DE UN ELECTRODO EN CONTACTO CON EL NUCLEO. EL NUCLEO ES TRANSPORTADO POR DELANTE DE UN PUESTO DE RECUBRIMIENTO B, EN EL QUE PARTICULAS DE POLVO QUE TIENEN UNA DIFERENCIA DE POTENCIAL CON TIERRA OPUESTA ESTAN MANTENIDAS EN UNA BANDEJA (18). LA SUPERFICIE DEL TAMBOR SE MANTIENE A LA MISMA DIFERENCIA DE POTENCIAL CON TIERRA QUE LAS PARTICULAS DE POLVO. EL POLVO ES ATRAIDO POR EL NUCLEO, PERO NO POR EL TAMBOR, Y RECUBRE LA SUPERFICIE VISTA DEL NUCLEO. EL TAMBOR TRANSPORTA EL NUCLEO RECUBIERTO POR DELANTE DE UN PUESTO DE FUSION C, EN EL QUE UN CALEFACTOR FUNDE EL POLVO PARA QUE FORME UNA PELICULA CONTINUA DE RECUBRIMIENTO. A CONTINUACION, SE GIRA EL NUCLEO Y SE TRANSFIERE A UN SEGUNDO TAMBOR (12 ), EN EL QUE, DE MODO ANALOGO, SE RECUBRE LA OTRA SUPERFICIE.
