PURPOSE:To enable appropriate air to be always fed to an agricultural product drying machine by a method wherein an aeration device is comprised of a temperature sensor for sensing a surrounding air dry ball temperature, a humidity sensor for sensing a relative humidity of surrounding air and a control means for controlling an adjusting means in response to detected information of these sensors. CONSTITUTION:A grain drying machine A and an aeration device B are connected through an aeration duct 1. An upper part of the aeration device B is provided with a control means 28. A temperature sensor 29 for sensing a surrounding air dry ball temperature and a humidity sensor 30 for sensing a surrounding air humidity are provided around a surrounding air suction part. The control means 28 intermittently controls the first and second blower fans 16, 19 and a compressor 27 in response to the detected information of these two sensors 29 and 30 or controls an opening or a closing of each of dampers 24 and 25. In this way, the surrounding air can be automatically heated or dehumidified in response to a surrounding air temperature and a relative humidity and then appropriate drying air can always be sent to the agricultural product drying machine. |
