Abstract
PURPOSE:To improve the detection accuracy of a hulling rate by selecting specific detected values except a maximum and a minimum value among detected values and finding a discrimination value from them when finding the discrimination value for discriminating between chaff and hulled rice. CONSTITUTION:When the hulling roll of the rice huller starts hulling rice, the mixed rice consisting of the hulled chaff and hulled rice is guided, grain by grain, to a sensor 2 for hulling rate detection and its hulling state is converted into an electric signal. A detected value selecting means A selects specific detected values except the maximum and minimum values among the detected values. A chaff and hulled rice discrimination value calculating means B finds the discrimination value for discriminating between chaff and hulled rice from the respective selected detected values. A hulling rate detecting means C compares the respective detected values of the sensor 2 with the discrimination value and detects the hulling rate from the results. Consequently, the detection accuracy of the hulling rate is improved.
