Abstract

UN ARMARIO CONGELADOR UTILIZA EFICAZMENTE UN REFRIGERANTE CRIOGENICO LIQUIDO CONJUNTAMENTE CON UN TRANSPORTADOR HELICOIDAL QUE CONDUCE UNA CARGA DE PRODUCTO A TRAVES DE UN GRADIENTE DE TEMPERATURA DENTRO DEL CONGELADOR. EL CONGELADOR TIENE UNA ENTRADA INFERIOR Y UNA SALIDA SUPERIOR PARA EL TRANSPORTADOR Y LA CARGA DE ALIMENTO QUE TRANSPORTA. EL ESCAPE DE VAPORES DEL CRIOGENO GENERADOS EN EL CONGELADOR POR EL CRIOGENO LIQUIDO ES CONTROLADO DE MODO QUE AL MENOS UN 80%, APROXIMADAMENTE, DE LOS VAPORES SALGAN POR LA SALIDA SUPERIOR, QUE ESTA EN LA ZONA MAS CALIENTE, ESTABLECIDA COMO PARTE DEL GRADIENTE DE TEMPERATURA EN EL CONGELADOR.
