Problems to be Solved by the Invention Grain is dried by being exposed to hot air generated from a burner while repeating circulation, and during this drying process, the temperature of the grain during drying exceeds a preset grain temperature. The temperature of the hot air generated from the burner is controlled so that the temperature does not rise, and the grains are dried. If so, grains with large moisture variations often have high moisture content, and even these high moisture grains may be exposed to high-temperature hot air until the set grain temperature is reached. As a result, the internal structure of the grains during drying may be destroyed, resulting in a decrease in taste.

Operate the tensioning start switch (30) of the operating device (3),
When starting the dryer (1) to load the grains and dry the grains, turn on the shell type control (30,
This dryer (1), moisture sensor (2B) and burner are operated by operating the filling amount spreader (35) and moisture dispenser (3B) to the specified positions, and by operating the drying start switch 2,000 (31). (4) is started, hot air is generated from this burner (4), this hot air is ventilated from the hot air chamber (16) to the drying chamber (13), passes through the exhaust chamber (17), and is sent to the exhaust fan (8). The grains that have been sucked and exhausted and stored in the storage chamber (11) are stored in this storage chamber (11).
