Abstract
SE DESCRIBE UN DISPOSITIVO DE CONTROL PARA PRODUCTOS CONGELADOS, CON CUYA AYUDA ES INDICADA EL EXCESO DE UNA TEMPERATURA DE ALMACENAMIENTO ADICIONAL IRREVERSIBLE. EN UNA UNION CALORIFICA CON EL PRODUCTO CONGELADO, SE ENCUENTRA UNA BOLSA DE PLASTICO PLANA CON PAREDES TRANSPARENTES, EN LA CUAL SE HA INTRODUCIDO UN MEDIO EUTECTICO CON UNA TRANSICION DEL ESTADO LIQUIDO/SOLIDO EN EL MARGEN DE 0 (GRADOS) C A AMENTE CON UNA DISPERSION MAGNETICA, COMPUESTA DE PIGMENTOS MAGNETICOS FINAMENTE DIVIDIDOS. EN LA BOLSA SE ADHIERE UNA TIRA MAGNETICA, QUE CONTIENE UNA MUESTRA ROTULADA MAGNETICAMENTE, Y LA CUAL PERMANECE UNIDA A LA BOLSA HASTA QUE EL DISPOSITIVO DE CONTROL CON EL PRODUCTO CONGELADO, ES ENFRIADO POR DEBAJO DE LA TEMPERATURA LIMITE. DESPUES ES RETIRADA LA TIRA MAGNETICA. AL SOBREPASAR LA TEMPERATURA LIMITE ADMITIDA, ES SUPRIMIDA POR MEDIO DE LA TIRA MAGNETICA LA ESTRUCTURA DE LA BOLSA, GENERADA OPTICAMENTE O LEIDA MAGNETICAMENTE, DE FORMA QUE ES POSIBLE UN CONTROL SIMPLE DEL PRODUCTO CONGELADO. LA INVENCION POSIBILITA NUMEROSAS VARIACIONES, MEDIANTE LA COMBINACION DE LA APLICACION DE TIRAS MAGNETICAS.
