The invention relates to an electrically operated preheater for dry material for the manufacture of green carbon-containing masses. The invention includes a preheater having a silo housing, a core, a top and a bottom electrode, a concentric feed pipe, an eccentric feed pipe, and a rotating feeding tool. The silo housing has a core located substantially within the silo housing extending substantially along its longitudinal axis. The top electrode is provided between the wall of the silo housing and the core, located proximate the top end of the silo housing, and the bottom electrode is provided between the wall of the silo housing and the core, located proximate the bottom end of the silo housing. The electrodes are connected to a power source. The rotating removal tool is located in the core proximate the eccentric feed pipe. The rotating feeding tool conveys the material for manufacture from the core into the eccentric feed pipe.
