ZhiXuan Tech has been deeply engaged in intelligent color sorting for 20 years, independently developing deep learning visual algorithms and high-precision photoelectric detection systems. With sorting accuracy up to 99.9% and the ability to detect defects as small as 0.01mm, we serve clients across 50+ countries and regions — from grain to minerals, from food to recycling — delivering reliable and efficient sorting solutions.
128-channel high-speed sorting, 16T/H capacity, precisely removes yellow grains, diseased spots, stones and other impurities.
256-channel flagship model, 32T/H capacity, AI algorithm identifies moldy grains and impurities, carryover ratio as low as 1:1.
64-channel compact design, suitable for multi-category sorting of beans, corn, peanuts and other coarse grains.
Specialized in nut sorting, accurately detecting mold, insect damage, and broken shells, safeguarding food safety standards.
Optimized for tea morphology, sorting tea stalks, yellow leaves, and foreign matter to enhance tea quality and appearance.
Small-channel precision sorting for dehydrated vegetables, seasonings, and other fine materials requiring high-accuracy sorting.
Large-channel industrial-grade sorting for grade improvement of quartz, feldspar, calcite and other minerals.
Efficient sorting of mixed plastics, metals, and glass, driving the upgrade of resource recycling industries.
Corrosion-resistant design for impurity removal and grade improvement of industrial salt, soda ash, and other chemical raw materials.

We're not just an equipment supplier — we're your long-term partner for production line efficiency. From sample testing to installation and commissioning, from operator training to lifetime maintenance, every step is backed by a professional team. Choosing ZhiXuan means lower carryover ratios, higher yield rates, and more reliable capacity assurance.
After deploying the ZS-256 color sorter, yellow grain rejection rate reached 99.9%, export qualification rate rose from 92% to 99.5%, saving over ¥2M in annual return losses.
The ZS-F128 nut sorter achieved 99.8% moldy grain detection rate with zero missed insect damage, helping the brand pass BRC and IFS dual certifications.
The ZS-M256 mineral sorter upgraded SiO2 grade from 98.5% to 99.6%, replacing manual sorting and saving ¥1.5M+ in annual labor costs.
The ZS-R128 sorter achieved automatic PET/HDPE/PP classification with 99.2% purity, 20x the efficiency of manual sorting, and ROI in just 8 months.
The ZS-F64 tea sorter precisely removes stalks and yellow leaves, elevating finished tea by 1-2 grades, boosting retail price by 30%, with a 95% repurchase rate.
Two ZS-256 units running in parallel process 800 tons of wheat daily, with 99.9% moldy grain rejection and flour whiteness improved by 2 grades — demand exceeds supply.
Thai Rice Exporter · Operations Director
"After deploying the ZS-256, our yellow grain rejection rate jumped from 95% to 99.9%, and export return rates dropped to nearly zero. What surprised me most was the 1:1 carryover ratio — almost no good product wasted. The equipment has run 18 months with zero downtime. Highly reliable."
Middle East Nut Processing Factory · General Manager
"We tried three color sorter brands, and ZhiXuan's AI algorithm had the highest recognition rate — not a single moldy nut slipped through. Even more critically, their after-sales team responds incredibly fast. A message at 2 AM gets a reply within 30 minutes, which is essential for our 24/7 production line."
Domestic Quartz Mining Enterprise · Technical Director
"We used to rely on manual sorting — 60 workers in three shifts, and quality was still unstable. After installing the ZS-M256, our ore grade went from 98.5% to 99.6%, and we recovered the investment in just 3 months. The AI algorithm even learns new mineral types automatically. Very flexible."
Brazilian Recycling Group · Project Manager
"The ZS-R128 helped us achieve fully automatic PET/HDPE/PP classification with purity over 99%. Before, manual sorting could handle 5 tons a day at most — now one machine easily processes 20 tons, and we recouped our investment in 8 months. Highly recommended!"
