Abstract
The present invention provides a microwave heating unit formed by comprising: a furnace body in which a fiber inlet and a fiber outlet are formed in a tube wall of a waveguide; and a microwave oscillator which guides microwaves into the waveguide. The microwave heating unit is characterized in that: continuous fibers to be heated are configured to have an inclination of an angle θ° with respect to the tube shaft of the waveguide and to travel therein; the angle θ° is 0.
Claims15
A microwave heating unit comprising:
- a furnace body that includes a fiber inlet and a fiber outlet which are formed on a tube wall of a waveguide;
- and
- a microwave oscillator for introducing microwaves into the waveguide,
- the continuous fiber as the heating subject being configured to run inside the waveguide with an inclination at an angle θ° with respect to a tube axis of the waveguide, the angle θ° satisfying 0<θ<90, and
- the fiber outlet being formed at a portion other than a terminal end portion of the waveguide.
