Brazil’s soybean exports have surged amid global demand, but mold contamination remains a major threat—leading to costly international returns. Fortunately, advanced
color sorters are now key to solving this, drastically boosting mold screening efficiency and cutting return risks.
Traditional mold screening for Brazilian soybeans relied on manual sampling, which was slow (only 500kg/hour) and missed hidden mold spots, resulting in a 8-12% return rate. Now,
soybean-specific color sorting machines—equipped with near-infrared (NIR) sensors and high-def cameras—change this. These
Optical Sorters detect mold’s unique spectral signals and subtle color changes (like pale yellow spots) that the human eye misses, screening soybeans at 5 tons/hour.
A high-performance
Industrial Color Sorter achieves a mold detection rate of over 99.5%, far exceeding manual work. For example, in Mato Grosso’s export hubs,
automatic color sorters have reduced soybean return rates from 10% to below 1.5%. These
Grain Color Sorter variants also adapt to Brazil’s humid harvest conditions, with waterproof components ensuring stable performance.
