抄録

Head-feeding combines separate grain from other materials by means of wind from a winnower. Although the combine operator can control the wind velocity, it is difficult to maintain the most appropriate speed by recognizing changes in the grain feed rate. In this study, we used a commercially available winnower to examine the relationship between grain loss and the grain feed rate at specific fan speeds, and aimed to reduce the grain losses that occur due to changes in the grain feed rate. We regulated the plate fan speed in accordance with the grain feed rate in order to achieve a designated rate of grain loss. As such, we were able to ascertain the relationship between grain loss and the grain feed rate for each fan speed. With this information we were able to achieve fan speeds that would restrict grain losses to within target limits.
