い恐れがある。[Prior Art and Problems to be Solved by the Invention] Before finishing the grain drying operation, when loading the grain into the storage tank, press the loading switch and move the loading conveyance system, such as the elevator, the upper transfer spiral, and the loading hopper. A spiral portion or the like is driven to detect that a certain amount of grain has been loaded into the storage tank using a pressure sensing sensor that operates in contact with the grain, and based on the detection result, the loading and conveying system was stopped. However, depending on the nature of the grain, such as the moisture content, the sensor may not be able to accurately detect the amount of grain stored because the diffusion state into the storage tank is not uniform and the volume may fluctuate.
