Abstract

PURPOSE:To detect the taste of selected large grains as, during drying of grains, grains during drying are selected into large grains and unriped grains by a coarse selecting machine. CONSTITUTION:In a state that grains during drying are selected into large grains and unriped grains by a grain size selecting device 3, the taste of the selected large grains is detected by a taste detecting device 8. From the taste detected result, drying is performed in a way that in, for example, a drying system, continuance control is made on dehumidifying drying or switching control to hot blast drying is effected. Further, by detecting the taste of grains during drying, a work after drying is shortened and by selecting according to a taste, high-efficient drying is executed.
