PURPOSE:To reduce the variance of a feed quantity detection by bringing the feed grain quantity detected by a feed quantity sensor to correction control to the prescribed quantity in accordance with grain moisture detected by a moisture sensor, while grains are being fed to a storage chamber. CONSTITUTION:Grains are fed of the inside of a storage chamber 1, while being diffused by a grain distributing device. When the inside of this storage chamber 1 reaches the prescribed quantity by said feed grains, a feed quantity sensor 2 detects this grains and when it is detected that the inside of the storage chamber 1 is filled with the grains, the fed of grains is suspended and a driving work of grains is started. The grains are exposed to hot air for ventilating a drying chamber and dried, while repeating a flow-down circulation in this drying chamber from the storage chamber 1. Subsequently, a moisture sensor 3 detects grain moisture from the time of feeding the grains, and when this moisture sensor 3 detects the same grain moisture as a finish target drying of the grains is stopped. |
