ことがある。Problems to be Solved by the Invention By sucking and exhausting the hot air generated by the front burner with the rear exhaust fan, this hot air is ventilated into the drying chamber, and the grains flowing down in this drying chamber are removed. In a dryer that dries by exposing it to hot air, during drying work when the outside air temperature is low, this low outside air passes through the burner section, and the burner is cooled by this low outside air and is used for combustion. The vaporization of the fuel deteriorates, and as a result, more carbon is generated, which may result in poor combustion conditions in the burner.

機の予熱風送風装置の構成とする。Means for Solving the Problems This invention is designed to vent hot air generated from a burner (1) at the front to a drying chamber (2) and suck and exhaust it with an exhaust fan (3) at the rear. A preheated air blowing device for a grain dryer is configured to blow the heat storage air stored in the heat storage device (4) to the burner (1) section when the temperature falls below a predetermined temperature. composition.

。Functions and Effects of the Invention While the grains flow down inside the drying chamber (2), the hot air generated from the burner (1) and the outside air passing through the burner (1) section are sucked by the exhaust fan (3). As a result, the two are mixed and ventilated to the drying chamber (2), where they are exposed to this hot air and dried. However, if the outside air temperature falls below a predetermined temperature during this drying operation, the heat storage device (4) Thermal storage air that has stored heat inside is blown from the heat storage device (4) to the burner (1), and the blown heat storage air and the hot air generated from the burner (1) are sent to the drying room (2). The grains are dried by ventilation.

で、このバーナ(1)は常に安定した状態で燃焼する。Conventionally, even during drying work when the outside air temperature was low, the intake air sucked into the burner (1) was this low outside air, but with the present invention, the outside air temperature is lower than a predetermined temperature. Then, the heat storage air stored in the heat storage device (4) is blown to the burner (1), so that the burner (1) is not exposed to low outside air and cooled. Therefore, this burner (1) always burns in a stable state.
