Application Overview — Food & Agriculture
Grain and Seed Sorting in Modern Recycling Facilities
Optical sorting of grains, seeds, nuts, and pulses is standard practice in food processing — removing discolored, damaged, or foreign-material kernels that would degrade product quality, reduce shelf life, or violate food safety standards. Agricultural optical sorters achieve >99.9% defect removal at throughputs up to 30 tonnes per hour for commodities like rice, wheat, coffee, and tree nuts.
Material Characteristics and Sorting Challenges
Grain sorting challenges: some defects are nearly invisible to RGB cameras (internal mold, incipient sprouting); product-specific defect definitions vary (a color variation that is acceptable in one grain type may be a defect in another); throughput requirements for commodity grains (rice, wheat) are an order of magnitude higher than for recycling applications; and food safety requirements (mycotoxin-producing molds, glass fragments, stones) demand near-zero false-negative rates for critical contaminants.
Recommended Sorting Technology Stack
RGB camera (color defect detection) + NIR (moisture content, internal defects via translucency differences) + SWIR (mycotoxin risk assessment) + 3D laser (shape defects: misshapen, broken, shriveled kernels). High-resolution cameras (0.05-0.1mm/pixel) and high-speed ejection (500-1000 Hz valve frequency) for commodity throughput.
Performance Benchmarks
| Metric | Target |
|---|---|
| Defect Removal | >99.9% |
| Foreign Material Removal | >99.99% |
| Throughput | 5-30 t/h (grain) |
| Resolution | 0.05-0.1mm/pixel |
These benchmarks represent achievable performance with modern sensor-based sorting equipment, assuming properly sized, well-maintained equipment operating on representative feedstock. Actual results depend on specific material composition, throughput, and operating conditions.
