とも可能である。 Next, the operation of this embodiment will be explained.
The grains are taken out from the tank 1 by a screw conveyor 2 serving as a grain feeding device mounted on the upper part of the moisture meter container 3, and introduced into the moisture meter container 3,
A sensor consisting of an anode 4 and a cathode 5 provided at the bottom of the screw conveyor 2 detects the capacitance of grain moisture in the moisture meter container 3, and a shaft rack is installed below the sensor. A rotary vane valve 6 serving as a flow valve causes the grains in the moisture meter container 3 to flow to a return chute that returns them to the tank 1,
Since the grain feeding rate of the rotary vane valve 6 is made smaller than the grain feeding rate of the screw conveyor 2, the grain structure near the sensor in the moisture meter container 3 is compressed by the small grain feeding capacity of the rotary vane valve 6. However, by increasing the grain density, capacitance can be measured in a state of almost uniform density, increasing the accuracy of grain moisture measurements. Note that the rotary vane valve 6 can also be provided in the supply section 7 of the moisture meter container 3 as a grain feeding device,
It is also possible to provide it separately at the bottom of the screw conveyor 2.

A sensor consisting of an electrode for detecting capacitance is provided, a rotary vane valve is provided below the sensor, and the amount of grain fed by the rotary vane valve is made smaller than the amount of grain fed by the screw conveyor. By compressing the grain near the sensor to increase and stabilize the grain density, the rotary vane valve can detect the moisture value in a state of almost uniform density and increase the accuracy of the moisture measurement. Since the length of the electrode is greater than the width of the electrode, the grains in the electrode part are ejected equally over the entire width, and each part of the electrode has approximately the same density, allowing accurate grain moisture values to be measured.
