Then, hot air (hot air) is guided to the mesh member 32 inside each drying stage 30. Then, each grain member 32 is allowed to pass through to evaporate moisture from the grain 60 that is a workpiece by the heat of hot air, and then the hot air is discharged from the air discharge pipes 33 to the outside of the main body 20. At this time, each temperature sensor 42 and each moisture meter 41 detect the temperature value and moisture value of each drying stage 30, and input the detected numerical value to the processing unit 44, and the moisture value of each drying stage 30 is set. When it becomes higher than the moisture value, the temperature of the drying stage 30 is raised, and when it becomes lower than the set moisture value, the temperature of the drying stage 30 is lowered.
Further, the processing unit 44 transmits a signal to the rotary motor 432 to adjust (accelerate or decelerate) the rotation speed of each rotary valve 431 and adjust the temperature of the hot air for drying. FIG. 8 shows a process flow in the case where the automatic drying apparatus 10 has four drying stages 30.

  Since the automatic drying method using the dryer according to the present invention has the technical means described above, by installing a plurality of drying stages 30 in the main body 20 and passing the grain 60 as a workpiece through each drying stage 30. The temperature value and moisture value of each drying stage 30 can be set individually. Moreover, since the temperature sensor 42 and the moisture meter 41 are installed in each drying stage 30, the moisture value of the grain 60 which is a workpiece can be detected in multiple stages.

In addition, when the moisture value of the grain 60 that is the workpiece does not reach a desired set value, the grain 60 is passed through each drying stage 30 by adjusting the temperature or the transport speed of each drying stage 30. Set to the desired moisture value.
According to this method, the moisture value is checked while the grain 60 as the workpiece is passed through each drying stage 30 to adjust the temperature or the transportation speed. Therefore, the moisture value is checked after all the drying steps are completed. There is no need. Therefore, since it is not necessary to repeat the grain drying process many times, the time, energy and cost of the drying process can be saved.

Furthermore, in the automatic drying method using the dryer according to the present invention, the grain 60 as the workpiece may be passed through several drying stages 30 as necessary, so that all the drying stages 30 need to be driven. There is no savings in energy and costs.
As described above, according to the automatic drying method using the dryer and the automatic drying apparatus according to the present invention, adjustment can be performed while detecting in multiple stages, so energy and cost can be saved by reducing the number of drying steps. can do.
