An outer wall is erected, and a roof is provided on the outer wall to surround the dryer.

In the outdoor grain dryer, one of the triangular prism-shaped spaces formed by the side surface of the dryer and the corners of the outer wall is used as a hot air chamber, and the space facing this is used as an exhaust chamber. The bucket elevator is erected in another space. The hot air chamber is closed at its upper end by a triangular plate and is connected to a hot air generator downwardly. An exhaust fan is attached to the opening.

In the outdoor grain dryer, the hot air sent from the hot air generator to the hot air chamber flows into the dryer and dries the grains in the dryer. Further, the exhaust air after drying the grain flows into the exhaust chamber and is discharged from the exhaust port by the exhaust fan.

By the way, the outdoor grain dryer is provided with a separate dust collection device for collecting straw pieces and dust (hereinafter referred to as "dust etc.") generated during the operation of the dryer. Since it is connected, there is a problem that the construction period will be prolonged.
In addition, the outdoor grain dryer needs to increase the power of the exhaust fan due to the pressure loss in the duct piping, which increases noise and running costs.
