In case of experiment, I used three varieties of grain sorters, namely, plane parallel type, plane folding fan type and zigzag type grain sorter.
Then, I Combined variously the three requistes, i. e. interval of wire, angle and flow rate, and checked up the weight of broken rice and unriper rice.
From this experiment, the result indicate a sifting characteristic curve of grain sorter. For that reason, we may call it the sifting chracteristic curve.
In this report, I checked the sifting characteristic curve with the result of experiment up to now.
