A heat generator assembly in a material processing apparatus includes a heater unit and an elongated deflector structure mounted adjacent thereto. The heater unit includes a plurality of elongated electric heating elements extending in generally parallel relation to one another and being operable for emitting heat radiation. The deflector structure is disposed along the electric heating elements and in circumferential relation partially about the electric heating elements for deflecting the heat radiation in a desired direction away from the heating elements. The heater unit also includes a pair of elongated electrically-conductive positive and negative electrodes and having spaced opposite end portions, an arrangement supporting the positive and negative electrodes and the electric heating elements in a spaced apart parallel relation to one another, and a plurality of connector elements electrically connecting selected ones of the opposite end portions of the electric heating elements with selected ones of the opposite end portions of the positive and negative electrodes so as to define at least one electrical circuit path between the positive and negative electrodes and through the electric heating elements.
