Abstract
PURPOSE: To enable to dehydrate an objective substance without injuring quality and appearance thereof by contacting the substance to be dehydrated with a substance having water abosorbing and holding capacity of 10 times or more based on the wt. thereof through a water permeable film.
CONSTITUTION: As dehydration methods, there are a method wherein a substance to be dehydrated is closely adhered and coated with a water permeable firlm directly and the coated substance is embedded in a substance having water absorbing and holding capacity, a method wherein a material comprising coating one surface of a permeable film with the substance having water absorbing and holding capacity is preliminarily prepared and the opposed surface thereof and the substance to be dehydrated are closely contacted, a method wherein the substance having water absorbing and holding capacity is entered between two water permeable films and sealed therein and the obtained sealed object is obtained sealed object is contacted with the substance to be dehydrated or coated therearound or a method stacking the same in a multi-layered form.
