Dielectric Oven

Dielectric Oven. An oven in which product heating is accomplished by creating an electrostatic field (q.v.) in which the product serves as the nonconducting dielectric substance and experiences a rise in temperature when subjected to the variable electric field. Such ovens are used mainly for rapidly reducing the moisture content (q.v.) of cookies (q.v.) and crackers (q.v.) subsequent to their baking.
