\begin{tabular}{l c c c c c c c c c c} \hline \hline \multirow{3}{*}{**Experimental Method**} & \multicolumn{6}{c}{V1—uncontaminated product; V2—artificially contaminated product with sunflower seeds; V3—product artificially contaminated with soy and sunflower seeds; Gs—good seeds; Bs—broken seeds; Ps—seeds with fusarium; Ai—artificial impurities; D—mechanical losses and dust; sb—soybean seeds; sf—sunflower seeds. * On average, from the material that is processed using the optical sorter, approx. 95.10% of the quantity reaches the “accept” output, whereas approx. 4.87% reaches the “reject” output, and a difference of up to 100% was reached by \" mechanical losses\" and “dust”;
* The quality of the category “good grains” generally improves by about 0.14%, the quality of the category “broken grains” generally improves by about 0.04%, the quality of the category “fusarium grains” improves by about 0.12%, and the quality of the category “artificial impurities” improves by about 0.60%;
* The quantity of good seeds in the reject represents, on average, about 65.74% of the total quantity from the reject-box, and represents (on average) 3.27% of the total good grains entered for processing;
* If the impurity of the base material is higher, then the amount of good seeds in the reject-box is also higher (e.g., with an impurity of 2.82%, the share of good grains in the reject is 54.51%; at an impurity of 4.47%, the share of good grains in the reject is 67.12%; and at a 6.93% impurity, the share of good grains in the reject is 75.59%);
* Associated with the total good grains entered for processing, the amount of seeds found in the reject box will increase with an increase in contaminants (e.g., with an impurity of 2.82%, the loss of good grains in the reject is 1.34%; at 4.47% impurity, the loss of good grains in the reject is 3.97%; and at 6.93% impurity, the loss of good grains in the reject is 4.50%);
* The average value of the ratio of impurities in the base material/percentage of the extracted impurities is found to be 1:0.16;
* The average value of the ratio of impurities in the base material/percentage of good grains extracted and lost in the reject is 1:0.70.
