PURPOSE:To reduce the wear and the damage of a sensor electrode part due to the shock of flowed-down grain by providing a storage means, where flowed- down grain is stored temporarily, in a moisture measuring part of a distributed moisture sensor. CONSTITUTION:Grains discharged from a drier 1 are sent to a distributing mechanism 11 through a conveyor 9 and an elevator 10 and are flowed down in the direction of an arrow through a grain flow passage 20. On the wall face of the flow passage 20, the moisture measuring part consisting of a distributed moisture sensor 21, a fixed electrode 22a, and a movable electrode 22b and a flowed-down grain storage means which stores temporarily flowed-down grain in this measuring part and consists of a member 23 surrounding the moisture measuring part and a shutter 24 are provided. When grain is flowed down with the shutter 24 closed, grains stored on the shutter 24 function as a buffer to prevent the wear and the damage of electrode parts 22a and 22b. |
