To prevent shape collapsing or deformation of a package by centrifugal force and prevent generation of dehydration unevenness or wrinkle, by simultaneously revolving and rotating plural packages provided at the same distance from the center of the rotational shaft of a centrifugal dehydrator.

Plural packages 1, 2, 3 and 4 provided at the same distance from the center of the rotational shaft 6 of the centrifugal dehydrator are revolved by a motor for rotating the rotational shaft 6. Package rotating shafts 1a, 2a, 3a and 4a are connected to a power source through a speed variable gear capable of varying rotational speed to adjust rotational speeds of the packages 1, 2, 3 and 4. By the process, fiber products can be dehydrated to ≤20% water content.
