The hot air enters into the hot air channels 1 and 1, passes through the grain flow channels 4, 4, c, and d, enters the exhaust channels 2, 2, , 2 . . . The dried hot air in the air is collected in the air exhaust passage connecting air passage 7 and is exhausted outside the machine by the suction fan 8 . Therefore, this hot air flows through each grain flow path 4, 4...a, b,
When the grain passes through stages 3 and 2, it is heated and dried. Then, during drying, hot air path 1,
A part of the hot air that has been divided into 1, E, and F is sucked into the hot air path connecting air duct 9 and collected, and after being sucked into the exhaust air path connecting air duct 7 from the communication hole 11, it is transferred to the machine. Ventilated outside. Therefore, these two hot air paths 1, 1,
Since the heat sensitive element 10 detects the temperature of the mixed hot air of E and F, even one heat sensitive element 10 can detect the average hot air temperature. Further, since the hot air at the time of this detection is circulated, the hot air does not stagnate and can be accurately detected.
