High frequency dielectric heating equipment is mainly used in following fields: Woodworking, like glue curing of (bent) plywood production, or edge glue (finger joint) board, assembling of door or frame, Drying, like wood drying, cookie/cake drying, textile drying etc High frequency heating is much different from other heating method like steam heating, hot water heating, electric heating which all heat from the surface of the material and gradually transfer temperature to its core. Rather, it penetrates the solid material and concentrates all power on the water or moisture within the material. This character makes it a fast, thorough, even, and at last power saving heating technic.
