Dielectric heating device

Abstract

A dielectric heating device includes: a transport unit configured to transport a medium in a transport direction; an electrode unit configured to dry the medium transported by the transport unit by dielectric heating, the electrode unit including a first electrode and a second electrode that face the medium; a voltage application unit configured to apply an AC voltage to the first electrode and the second electrode; and a control unit configured to control the transport unit. The second electrode includes a first portion and a second portion that sandwich the first electrode in the transport direction. The first portion is disposed upstream of the second portion in the transport direction. The first electrode and the second electrode are formed such that a heating amount of the medium by an electric field formed between the first electrode and the first portion is larger than a heating amount of the medium by an electric field formed between the first electrode and the second portion.
