Abstract

Un proceso de secado por congelacion incluye un paso de congelacion para girar el frasco (1) alrededor de su eje longitudinal a una velocidad no menor que aquella requerida para mantener por fuerza centrífuga el material acuoso que se va a secar por congelacion en la forma de un forro (7) en las paredes interiores del frasco (1) y luego se somete el material a condiciones de congelacion para congelarlo en la forma del forro (7). En otro aspecto de la invencion, el proceso de secado por congelacion también incluye el paso de secar el material congelado de forro (7), al dirigir calor radialmente hacia dentro desde un bloque de calentamiento (14) hacia el material congelado de forro (7) e incrementar la temperatura durante un período de tiempo para secar el material congelado de forro (7).
