  However, in the conventional drying processing apparatus, when a plurality of drying processing steps are continuously performed, the temperature inside the temperature-controlled room is low around room temperature when one drying processing step is completed. For this reason, in order to start the next drying process, it is necessary to raise again the temperature in the vacuum dryer once it became low temperature.

[Characteristics of the sealed container and the drying apparatus of the first embodiment]
As mentioned above, in the airtight container 5 of this embodiment, since the gas state is changed in units of the airtight container 5, the airtight container 5 can be made small. Therefore, the sealed container 5 in which the treatment material 6 is accommodated can be manufactured using a relatively thin plate material. Therefore, compared with the conventional drying processing apparatus which changes the whole gas state in a temperature-controlled room, the amount of gas consumption and the energy required for the change of a gas state can be reduced.

And the heat of this separator 43 can be transmitted to the processing material 6 by radiation. Therefore, each processing material 6 can be efficiently dried.

  Further, in the drying processing apparatus 100 of the present embodiment, when the drying process is completed in the temperature-controlled room 2, the sealed container 5 is transported to the outside of the temperature-controlled room 2. Therefore, unlike the conventional drying processing apparatus, it is not necessary to cool the inside of the temperature-controlled room 2 in order to take out the processing material 6 to the outside of the temperature-controlled room 2, and the inside of the temperature-controlled room 2 can be maintained at a high temperature. Therefore, even when a plurality of drying treatment steps are continuously performed, the temperature in the temperature-controlled room 2 can be maintained at a high temperature, so that the heat energy required for the drying treatment step of the treatment material 6 can be reduced.

  Moreover, in the drying processing apparatus 100 of this embodiment, in the drying processing process of the processing material 6, each of the stop time (DELTA) t1- (DELTA) t3 when the airtight container 5 has stopped at each vacuum position P1-P3 is drying of the processing material 6. However, since the time required for drying the treatment material 6 is ensured by the sum of the stop times Δt1 to Δt3, the treatment material 6 can be sufficiently dried.

  Further, in the drying processing apparatus 100 of the present embodiment, in the drying processing step of the processing material 6, even if the processing material 6 is a material that generates volatile matter in the sealed container 5 during drying, the first vacuum position. Volatile components can be extracted from the sealed container 5 by evacuation at P1, and subsequently, volatile components can be extracted from the sealed container 5 by evacuation also at the second vacuum position P2 and the third vacuum position P3. Therefore, it is possible to reliably prevent an increase in pressure in the sealed container 5 due to generation of volatile matter in the sealed container 5 and maintain a predetermined pressure state (for example, a vacuum state).

  Moreover, in the drying processing apparatus 100 of this embodiment, in the drying process of the processing material 6, the pressure in the sealed container 5 is increased while the sealed container 5 is transported from the first vacuum position P1 to the third vacuum position P3. Can be changed. Therefore, it is possible to perform a durability test by changing the pressure of the treatment material 6. Further, the material components having different vapor partial pressures contained in the treatment material 6 can be evaporated while controlling the order of evaporation. In addition, since a large amount of water evaporates at the first vacuum position P <b> 1, the latent heat of vaporization is lost, and thus the temperature of the processing material 6 may decrease. In this case, since the gas density in the sealed container 5 can be increased by pressurizing the inside of the sealed container 5 in order to recover the temperature drop early, the amount of heat absorbed by the processing material 6 can be increased.

  Moreover, in the drying processing apparatus 100 of this embodiment, since the sealed container 5 is conveyed one by one in the temperature-controlled room 2 in the drying process of the processing material 6, two or more sealed containers 5 are simultaneously transferred to the temperature-controlled room 2. Compared with the case where it arrange | positions in, it can prevent that the temperature currently maintained in the temperature-controlled room 2 changes with heat loss largely.

  Moreover, in the drying processing apparatus 100 of this embodiment, in the drying process process of the processing material 6, by supplying high temperature nitrogen gas in the airtight container 5, the processing material 6 is directly heated by heat exchange with this nitrogen gas. Therefore, the treatment material 6 can be dried earlier.
