PURPOSE:To obtain an extreme infrared-ray generator of an excellent generation efficiency which can heat an inside substance evenly by composing the generator in a cylindrical or box form with the wall surface of a plane-form heater whose heating element is made of a carbon fiber. CONSTITUTION:An extreme infrared-ray generator main body 1 furnishes a coverage layer 2 at the outer surface, and a heating element 3 and an electric insulator 4 at the inside. From the coverage layer 2, electrodes 5 are picked up, a current is applied between the electrodes 5 to heat the heating element 3, the hollow 6 in the cylinder is made in a passage of a substance to heat, and a heating process can be carried out continuously. In a continuously drying device for fiber using such a generator, for example, a fiber 7 given a process agent is heated by extreme infrared rays from the generator 1, and since the heating is a direct heating without using a medium such as the air, the heating efficiency is high, and the heating process can be carried out in a short time. |
