Abstract

DISPOSITIVO ESTANCO AL AIRE BAJO PRESION COMPLETAMENTE ENCERRADO EN UN TAMBOR GIRATORIO (12). EL DISPOSITIVO (10) SE CONSTRUYE DE FORMA QUE PUEDA SER COMPLETAMENTE SUMERGIDO EN EL LIQUIDO. EL DISPOSITIVO TIENE UNA CAMARA LLENA DE LIQUIDO (32). LA PULPA ES ALIMENTADA AL DISPOSITIVO A TRAVES DE UNA ENTRADA DE PULPA (14). LA PULPA ES FORMADA Y COMPACTADA PARA FORMAR UN ENMARAÑADO DE PULPA. DESPUES DE LAVAR EL ENMARAÑADO DE PULPA SE COMPACTA DE NUEVO. EL ENMARAÑADO DE PULPA SE QUITA DESDE EL TAMBOR EN UN PUNTO DESMONTABLE SITUADO EN LA CAMARA LLENA DE LIQUIDO, DE ESTA FORMA SE CONSIGUE UNA SUSPENSION DE PULPA EN LA CAMARA. LA SUSPENSION SE QUITA DESDE EL DISPOSITIVO A TRAVES DE UNA SALIDA DE PULPA (61) QUE SE EXTIENDE DESDE LA CAMARA LLENA DE LIQUIDO (32).
