Microwave radiating device, connecting type microwave radiating device, and methods of producing sugar ingredient from plant materials

A microwave radiating device which treats a material by radiating microwaves to the material, comprising:

• a radiating means containing a microwave radiating source;
• a container which accommodates the material therein;
• the container having:
• a supply means for providing the material to the container,
• a discharge means for discharging the material from the container, and
• a microwave receiving section where the microwave enters the container through a dielectric material;
• and
• at least one layer composed of a non-dielectric material, the layer provided between an inside of the container and an atmosphere outside of the container;
• wherein the radiating means and the container are detachably connected.

A connecting-type microwave radiating device, comprising:

• at least two microwave radiating devices, the microwave radiating devices coupled to each other, and each of the microwave radiating devices comprising;
• a radiating means containing a microwave radiating source;
• a container which accommodates a material therein;
• the container having:
• a supply means for providing the material to the container,
• a discharge means for discharging the material from the container, and
• a microwave receiving section where the microwave enters the container through a dielectric material;
• at least one layer composed of a non-dielectric material, the layer provided between an inside of the container and an atmosphere outside of the container;
• wherein the radiating means and the container are detachably connected;
• wherein a discharge means in one of the microwave radiating devices and a supply means in another of the microwave radiating devices adjacent to the one of the microwave radiating devices are detachable from each other, and
• wherein when the discharge means and the supply means are coupled, the containers of the one and the another of the microwave radiating devices jointly form a passage for a flow of the material.
