なく、乾燥終了時を的確に検出することができる。Next, the operation will be described. In FIG. 1, after the material 1 to be dried is put into the storage portion 2 for material to be dried, the lid 4 for charging the material to be dried is closed, and the condensing section 2 is placed in the processing chamber 7. When the microwave oscillator 9 is operated after confirming that the processing chamber door 16 is closed, the microwave passes through the waveguide 10 and passes from the microwave introduction unit 11 to the processing chamber 7.
Irradiated inside. If the processing chamber door 16 is not completely closed, the door opening / closing detector 19 detects the microwave oscillator 9.
Does not work. The microwaves radiated into the processing chamber 7 penetrate through the drying object charging port 4 formed of the microwave transmitting material, and start heating the drying object 1 in the drying object storage unit 2. In particular, the microwaves are selectively absorbed by the moisture in the dried object 1 to generate water vapor 5, and
Dries. Further, the blower fan 12 is operated together with the microwave oscillator 9 to send the air 13 from the air inlet 14 into the processing chamber 7. The air 13 flows out of the processing chamber 7 from the air outlet 15 after air cooling the outer surface of the condenser 3. The object 1 to be dried 1 is cooled by air cooling the outer surface of the condensing section 3.
Most of the water vapor 5 generated from the condensate is condensed on the inner surface of the condensing vessel 3 to form condensed water 28, and is discharged from the condensed water outlet 20 to the lower side of the condensed part 3. The condensed water outflow portion 20 does not discharge solids that would cause clogging in the sewer path, so that the environment is not adversely affected. As the drying process proceeds, the temperature of the steam 5 generated from the object 1 to be dried increases. Accordingly, the microwave oscillator 9 is turned on and off so that the temperature of the temperature detector A17 closer to the object 1 to be dried does not exceed a predetermined temperature, and the drying process is continued while the burning of the object 1 is suppressed. I do. With the on / off control, the temperature of the temperature detector B18 remote from the object 1 repeats rising and falling, but the temperature rise value decreases as the amount of water vapor decreases. Therefore, by ending the drying process when the temperature rise value of the temperature detector B18 farther from the object to be dried 1 becomes equal to or lower than the predetermined temperature, it is possible to accurately detect the end of drying without causing scorching. Can be.

17 is located in the object-to-be-dried storage section 2 and the temperature detector B18 farther from the object-to-be-dried 1 is located between the object-to-be-dried storage section 2 and the condensing section 3, so that control with excellent responsiveness is achieved. ,

る。When the temperature of the temperature detector A17 closer to the object to be dried 1 reaches 105 to 110 ° C., the microwave oscillator 9 is turned off. When the temperature reaches 100 ° C., the microwave oscillator 9 is turned on. By terminating the drying process when the temperature rise value of the other temperature detector B18 becomes 5 ° C. or less, the drying rate (the amount of water loss after the treatment / the water content before the treatment) can be determined without causing scorching. It is possible to increase.

Only the drying process is controlled and the end is detected. When the temperature of the steam 5 generated from the object 1 increases with the progress of the drying process, the microwave oscillator 9 is turned on and off so that the temperature of the temperature detector A17 does not exceed a predetermined temperature. The drying process is continued while suppressing the scorching of 1. With the on / off control, the temperature of the temperature detector A17 repeatedly rises and falls, but the time from when the microwave oscillator 9 is turned off to when it is turned on becomes shorter as the amount of water vapor decreases. Therefore, by ending the drying process when the time from when the microwave oscillator 9 is turned off to when it is turned on is equal to or shorter than a predetermined time, the end of drying can be accurately detected without causing scorching. .
