Then, the seed bag P is placed on the lower placement shelf 33. Then, the lower opening / closing lid 21 is closed, and the upper mounting shelf 33 is disposed in the mounting space S1 of the accommodation space S. Then, the upper opening / closing lid 20 is closed and the inside of the processing chamber 11 is substantially sealed, so that the process # 4 is completed.

When the squeezing step # 4 is completed, a drying air blowing step # 5 is then performed.
In the drying blow process # 5, the operation of the blower 38 is continued, and the heat of oxidation of the crushed iron powder coated seeds F is released to the air circulating in the processing chamber 11. When the third set time C3 has elapsed since the start of the drying air blowing process # 5, the drying air blowing process # 5 is completed.

  A predetermined amount of water is stored in the water storage space S2 during the moisture supply process # 2, the oxidation blowing process # 3, the defrosting process # 4, and the drying blowing process # 5. The water vapor evaporated from the water stored in the water storage space S2 is generated by the blower 38 and circulates on the wind flowing along the circulation path, so that the oxidation of the iron powder-coated seed F is promoted.

  At this time, since the bottom surface of the air guide case 23 is located at a lower position from the air blower 38 side toward the water storage space S2, the water droplets are attached even when water droplets adhere to the air guide case 23. And the like naturally flow down to the water storage space S <b> 2 along the bottom surface of the air guide case 23.

  In addition, during the moisture supply process # 2, the oxidation blowing process # 3, the defrosting process # 4, and the drying blowing process # 5, the heater 17 is based on the first target temperature A1 that is a temperature suitable for the oxidation process. Be controlled. That is, when the second temperature sensor 60 detects a temperature lower than the first target temperature A1, the heater 17 operates and the inside of the processing chamber 11 is heated. On the other hand, when the second temperature sensor 60 detects a temperature equal to or higher than the first target temperature A1, the heater 17 is stopped and the heating in the processing chamber 11 is stopped.

When the dry air blowing process # 5 is completed, a hot air blowing process # 6 is then performed.
In the warm air blowing process # 6, all the water stored in the water storage space S2 is drained by the drainage section 32. In the hot air blowing process # 6, the heater 17 is controlled based on the second target temperature A2 suitable for hot air drying higher than the first target temperature A1. That is, when the second temperature sensor 60 detects a temperature lower than the second target temperature A2, the heater 17 operates and the inside of the processing chamber 11 is heated. On the other hand, when the second temperature sensor 60 detects a temperature equal to or higher than the second target temperature A2, the heater 17 is stopped and the heating in the processing chamber 11 is stopped. And the operation | movement of the air blower 38 is continued and the drying process of the iron powder coating seed F by which the oxidation process was completed is performed with the warm air which circulates the inside of the process chamber 11. When the fourth set time C4 has elapsed since the start of the hot air blowing process # 6, the heater 17 is stopped and the hot air blowing process # 6 is completed.

When the hot air blowing process # 6 is completed, a cooling process # 7 is finally performed.
In the cooling step # 7, the operation of the blower 38 is continued, and the iron powder-coated seed F that has been subjected to the oxidation treatment and the drying treatment is cooled. When the fifth set time C5 has elapsed since the start of the cooling step # 7, the blower 38 is stopped and the cooling step # 7 is completed.

  During the moisture supply process # 2, the oxidation blowing process # 3, the defrosting process # 4, the drying blowing process # 5, and the hot air blowing process # 6, the control device 18 determines that the temperature detected by the temperature detection means 15 is a threshold value. The cooling unit 16 is controlled based on whether or not the temperature is exceeded.

  Specifically, the first shutter device 46 of the cooling means 16 is controlled by a first threshold temperature B1 that is higher than the first target temperature A1 and lower than the second target temperature A2. The control device 18 is configured to control the first shutter device 46 to an open state when at least one of the first temperature and the second temperature exceeds the first threshold temperature B1. In other words, if at least one of the first temperature detected by the first temperature sensor 59 and the second temperature detected by the second temperature sensor 60 is less than the first threshold temperature B1, the first shutter device 46 is in a closed state, and the intake port 45 is in a substantially closed state. On the other hand, when at least one of the first temperature detected by the first temperature sensor 59 and the second temperature detected by the second temperature sensor 60 detects a temperature equal to or higher than the first threshold temperature B1, the first shutter device 46 is used. Becomes an open state, and the intake port 45 is opened, allowing the outside air to flow from the intake port 45 into the processing chamber 11 and cooling the processing chamber 11.

  Further, the second shutter device 48 of the cooling means 16 is controlled by the second threshold temperature B2 higher than the first threshold temperature B1 and the second target temperature A2. When the temperature of at least one of the first temperature and the second temperature exceeds the second threshold temperature B2 larger than the first threshold temperature B1, the control device 18 controls the second shutter device 48 to be in the open state. It is configured. In other words, when at least one of the first temperature sensor 59 and the second temperature sensor 60 detects a temperature lower than the second threshold temperature B2, the second shutter device 48 is closed and the exhaust port 47 is substantially closed. It will be in the state. On the other hand, when at least one of the first temperature sensor 59 and the second temperature sensor 60 detects a temperature equal to or higher than the second threshold temperature B2, the second shutter device 48 is opened and the exhaust port 47 is opened. The outside air can flow into the processing chamber 11 from the exhaust port 47, and the temperature in the processing chamber 11 is cooled.

  That is, the temperature in the processing chamber 11 is equal to or higher than the second threshold temperature B2 during the moisture supply process # 2, the oxidizing air blowing process # 3, the defrosting process # 4, the dry air blowing process # 5, and the hot air blowing process # 6. Then, both the first shutter device 46 and the second shutter device 48 are opened, and external air is passed through the processing chamber 11 so that the temperature in the processing chamber 11 is quickly cooled.

  As described above, according to the iron powder-coated seed oxidation preparation apparatus of the present embodiment, the oxidation process and the drying process are performed quickly while suitably releasing the heat of oxidation caused by the oxidation of the iron powder by the preparation process performed as described above. Therefore, it is possible to suitably obtain an iron powder-coated seed F that has been subjected to oxidation treatment and drying treatment having a good germination rate.
