Abstract
Procedimiento para el control de un proceso de liofilización, en el que: el producto congelado, situado dentro de una cámara al vacío y sobre unas superficies de temperatura regulable, se somete primero a un secado principal y a continuación a un secado posterior, durante el secado principal se realiza la medición constante de la temperatura del hielo contenido en el producto a secar, en el tránsito del secado principal al secado posterior se modifica la presión de la cámara y/o la temperatura de las superficies, caracterizado porque: las modificaciones de la presión, típicas del tránsito del secado principal al posterior, y de la temperatura de las superficies se llevan a cabo en dependencia de la reducción de la temperatura del hielo.
