Optical Sorter VS Traditional Manual Sorting — Efficiency Comparison:Optical sorters are far more efficient than manual sorting for industrial production.   Optical Color Sorter 1. Speed: Hundreds to thousands of grains are scanned per second. A medium machine can process 2–10 tons per hour. 2. Consistency: Stable sorting standard; no fatigue, no mood difference. 3. Accuracy: High purity, controllable good-material loss rate. AI models spot tiny mildew, discoloration and foreign impurities. 4. Labor: Only 1 operator for feeding and monitoring. 5. Long run: Works 24/7 continuously. 6. Weakness: Higher upfront investment, needs power and compressed air, regular maintenance.    Manual Sorting 1. Speed: Slow. One worker usually sorts only 50–150 kg per hour. 2. Consistency: Easy to get tired after long hours; quality fluctuates a lot. 3. Accuracy: Hard to find small defects, easy to miss bad grains. 4. Labor: Needs many workers, high recurring labor cost. 5. Long run: Hard to work overtime; high turnover of workers. 6. Weakness: Low output, unstable quality, rising labor cost year by year.   Conclusion:An optical sorter greatly outperforms manual sorting. It runs nonstop with high, stable purity and cuts labor costs. Manual sorting is slow, inconsistent and costly in the long term.
