A material to be dehydrated wrapped in a semipermeable sheet is dipped in a dehydrating solution (10) to cause part of the water contained in the material to be absorbed into the dehydrating solution to dehydrate the material, and the water-absorbed dehydrating solution is cooled by cooling means (200) and concentrated on concentrating means (300) to adjust its temperature and concentration, and sterilized as needed, to be used repeatedly for the dehydration treatment, thereby dehydrating a large amount of material to be treated without changing the quality of the material under consistent conditions. |
