To provide a grain drier capable of appropriately regulating grain temperature by solving such a problem that hot air blows-by to the exhaust side and the hot air does not properly actuate grain particles when charged amount of the grain particles is reduced, in the grain drier which circulates a part of exhaust to the hot air side by means of a hot air return means, mixes the exhaust with the hot air and utilizes the mixed air.
A grain drier includes an exhaust return means, an exhaust regulating means which regulates a proportion of outflow exhaust and return exhaust, and a rotation number regulating means which changes rotation speed of an exhaust fan (6). By using the grain drier in which, during drying operation, a control device (17) controls the proportion of the return exhaust by means of the exhaust regulating means and the number of rotations of the exhaust fan (6) is controlled by means of the rotation number controlling means, such a problem that hot air blows-by to the exhaust side and the hot air does not properly actuate grain particles when charged amount of the grain particles is reduced is solved.
