In the figure, a processing container 1 is formed into a cylindrical shape and is arranged at an angle, and a groove 2 is formed on the lower side wall of the processing container 1, and a screw-type discharger 3 extends from the bottom to the upper part of the groove 2. An outside discharge port 4 is formed near the upper end of the discharge machine 3. The processing liquid 6 is supplied into the processing container 1 by a quantitative supply pump 7, and is controlled by a liquid level gauge 8 so that the liquid level 5 is at a position lower than the discharge port 4. Also, a stirring blade 12 for stirring and mixing the material to be processed in the container 1
This stirring IJi 12 is attached to a rotating shaft 40 rotated by a motor 13.

れている。An irradiation hole 30 is formed in the upper part of the processing container 1, and an electromagnetic wave oscillator (not shown) is connected to this irradiation hole 30 via a waveguide 10. A partition plate 11 made of Teflon or quartz plate is placed in the waveguide 10 near the irradiation hole 30 to prevent liquid dust evaporated in the processing container 1 from entering the waveguide. There is. Also container 1
An exhaust pipe 14 is connected to the upper part of the exhaust pipe 1a, and a condenser 15 is installed at the other end of the exhaust pipe 1a.The water vapor evaporated in the processing container 1 passes through the exhaust pipe 14, and the moisture is removed by the condenser 15. The water is separated and taken out as recovered water 16. Further, one feeder for feeding an additive 18 is installed in the container 1.

しつつ蒸発を行なわせる。In the above configuration, electromagnetic waves 9 are irradiated through the waveguide 10 while the processing liquid 6 is supplied to the container 1 at a predetermined ratio of 1 to 5, and stirred by stirring 9 by 12. ′
The processing liquid is heated and evaporated by the FX magnetic wave irradiation, and the evaporated material is sent from the exhaust pipe 14 to the condenser 15, where the recovered water 16 is separated and the water vapor is released to the outside by the pump 17. . The concentration of the treated liquid gradually increases due to the evaporation of water vapor, but in order to make this effect more effective, it is stirred by the stirring blade 12, and the discharger 3 is rotated in the opposite direction to move the precipitate into the container 1. Make sure to push it to the bottom. In addition, in order to facilitate precipitation of the processing liquid, or when the dried product is extremely resistant to adhesion to the inner wall of the processing container 1 or the stirring blade 12, the additive 18 is supplied by the feeder 19 while the evaporation is prevented. Let them do it.
