Action of an electric field on the water molecules of moist materials

The study of thawing by an electric field, electro\|osmotic dehydration and high voltage drying is a new field in electrostatics that is attracting much attention as it provides a new way for dehydration and thawing. Experiments show that the application has many merits, such as no rise in temperature of the material, no damage to the nutritional ingredients and non\|pollution of the environment. Recent advances in China and abroad are summarized, and it is pointed out that the common factor is the action of the electric field on the water molecules.
