の乾燥、焼或が出来ない欠点があった。However, in the conventional method, the air temperature in the drying chamber (1) is controlled by a thermally responsive body, and with this, the sensitivity of the thermally responsive body is low and the temperature differential is large, which means that the width of the variation in the heater surface temperature is also large. In other words, the radiation wavelength of the far infrared rays varies, which has the disadvantage that it is not possible to ideally dry and burn the seaweed.

ことがわかる。At this time, as shown in Figure 6, both the front and rear ends of the reflector (5) are slightly bent upwards to reflect the far infrared rays leaking to the front and back of the seaweed (10) on the conveyor (8). , it is possible to effectively project far infrared rays from the bottom surface onto the front and rear ends of seaweed (lO), which tend to be insufficiently heated.
Since far infrared rays of 0.75 to 3 μm have stronger optical properties than near infrared rays of 0.75 to 3 μm, the distance between the heating source that emits far infrared rays and the heated object directly affects the occurrence of uneven heating. The irradiation can be performed in such a way that there is no cracking between the heating source and the object to be heated. Figure 7 shows Vienna (
It shows a blackbody spectral radiant energy curve based on the displacement law of Wien), and in the temperature range of 400°C to 450°C, the wavelength at which the radiant energy density is maximum is around 3 μm to 9 μm. It can be seen that it is possible to radiate electromagnetic waves with

でき、品質の優れた海苔を得ることができる。Therefore, by controlling the heater surface temperature of the far-infrared radiation heater installed in the drying room to 400°C to 450°C,
Electromagnetic waves with wavelengths around 3 μm to 9 μm are radiated from the surface of this heater with extremely high efficiency, as shown in Figure 8 (a).
) and (b), the far-infrared absorption spectrum of seaweed shows strong absorption at wavelengths of 3 μm, 6 hm, and 9 μm. Therefore, as mentioned above, the temperature is detected by the plurality of temperature sensing elements (14) attached to the surface of the planar far-infrared heater (13) in a heat conductive manner, and the temperature is detected by the control unit (2).
0), by controlling the heater surface temperature uniformly at 400°C to 450°C, the emitted far infrared rays of 3 to 9 μm penetrate deeply into the interior of the seaweed (10) and are absorbed. Because the inside of the seaweed (10) is uniformly heated, the drying of the seaweed (10) and the unevenness of burning due to the fluctuation of the radiation wavelength of the far infrared rays due to the fluctuation of the heater surface temperature due to the temperature control in the conventional drying room (7). It is possible to prevent the occurrence of seaweed, and to obtain seaweed of excellent quality.

By controlling the rotation speed of the motor (11) by the control unit (20), the seaweed (10) in the drying chamber (7) is
The drying and baking time can be adjusted by controlling the transportation speed of the seaweed (10), and the seaweed (10) of stable quality can always be obtained. In addition, the reflector plate (15) can prevent the ends of the Yumihachi seaweed from being insufficiently heated, and the effect of preventing uneven drying and uneven baking of the seaweed can be enhanced.
