Fanchi-tech Bulk Product X-ray Inspection System: Precision Contamination Control for Bulk Food, Nut & Grain Processing
For manufacturers of bulk food, nuts, grains, and agricultural products, foreign body contamination is one of the most critical threats to brand reputation, regulatory compliance, and operational profitability. Even tiny contaminants such as stones, metal fragments, glass shards, or bone pieces can trigger costly recalls, regulatory penalties, and irreversible damage to consumer trust. NutriGrain Italy, a leading producer of bulk premium nuts, grains, and baking ingredients in Italy, turned to Shanghai Fanchi-tech Machinery Co., Ltd. to solve its bulk product inspection challenges. By deploying our Fanchi-tech Bulk Product X-ray Inspection System, NutriGrain eliminated contamination risks, reduced product waste, and secured full compliance with EU food safety and BRCGS standards.
The Challenge: Contamination Risks and Inspection Bottlenecks in Bulk Processing
NutriGrain Italy processes over 80 tons of bulk food products daily, including shelled almonds, walnuts, cashews, wheat, oats, and baking raw materials. In early 2025, the company faced a severe operational and compliance crisis:
- Uncontrolled Contamination Risks: Legacy metal detectors only detected metallic contaminants, failing to catch non-metallic threats such as 0.8mm glass shards, small stones, and bone fragments. A glass contamination incident in a batch of bulk almonds triggered a warning from the European Food Safety Authority (EFSA), resulting in a regional recall that cost 65000 EUR in direct expenses and damaged its relationship with a major European retail partner.
- High False Reject Rates: Bulk product stacking created imaging interference on outdated X-ray systems, leading to a 12% false reject rate. This resulted in 3.2 tons of qualified bulk nuts being discarded weekly, costing 4800 EUR in monthly material losses.
- Hygiene and Compliance Gaps: The old inspection system had crevice-ridden construction that trapped food residues, creating bacterial growth risks and failing BRCGS food safety audits.
- Production Inefficiency: 30% of bulk products required slow manual re-inspection, slowing production line speed by 25% during peak harvest seasons and causing shipment delays.
- Regulatory Non-Compliance: Legacy equipment failed to meet the latest EU 178/2002 and BRCGS standards, putting NutriGrain’s entire production license at risk.
Our bulk food products are the foundation of our business, but contamination risks and inefficient inspection were threatening our compliance and profitability, said Luca Rossi, Quality Director at NutriGrain Italy. We needed a bulk-specific X-ray system that could detect all types of contaminants, reduce false rejects, and keep our high-volume lines running at full speed.
The Solution: Fanchi-tech Bulk Product X-ray Inspection System
After evaluating 7 global competitors, NutriGrain selected the Fanchi-tech Bulk Product X-ray Inspection System for its bulk-optimized design, high-sensitivity detection, and food-grade hygienic construction. As shown in our product photos, the system features a full 304 stainless steel frame, high-resolution touchscreen control panel, emergency stop button, status indicator light, high-power X-ray generator, pneumatic automatic reject mechanism, and industrial-grade adjustable support legs—all engineered for 24/7 bulk food processing operations.
1. High-Sensitivity X-ray Detection for Stacked Bulk Products
Equipped with a high-performance X-ray generator and AI-powered image processing algorithm, the system delivers ultra-clear, high-contrast imaging that penetrates stacked bulk nuts, grains, and agricultural products. It detects all types of contaminants, including:
- Ferrous, non-ferrous, and stainless steel fragments as small as 0.3mm
- Glass shards as small as 0.5mm, hard plastic as small as 0.6mm, stones, and bone pieces
This eliminates the blind spots of traditional metal detectors, ensuring 100% detection of both metallic and non-metallic contaminants in bulk products. During on-site validation, the system achieved a 100% detection rate for all test contaminants in bulk almond, walnut, and wheat batches.
2. Bulk-Specific Pneumatic Reject Mechanism
The system’s left-side pneumatic hopper reject mechanism is purpose-built for bulk products. It gently and rapidly removes contaminated batches from the production line without jamming, damaging, or wasting qualified products. This reduces the false reject rate to less than 0.8%, cutting weekly product waste from 3.2 tons to just 224kg.
3. Food-Grade Hygienic Design for Bulk Processing
The full 304 stainless steel frame features a crevice-free, modular construction that supports daily high-pressure washdowns and CIP (Clean-in-Place) processes. Removable components and smooth, seamless surfaces eliminate food residue buildup, reducing cleaning time by 40% and minimizing bacterial growth risks, fully meeting BRCGS and EU food hygiene requirements.
4. Intelligent Operation and Regulatory Compliance
The user-friendly touchscreen control panel stores 50+ product presets, enabling SKU switching in just 15 seconds—down from 15 minutes with manual calibration on legacy systems. The system also:
- Automatically logs 1000000+ inspection records, images, and batch data for audit-ready traceability
- Meets EU 178/2002, BRCGS, FDA, and HACCP food safety standards
- Reduces operator training time by 50% with an intuitive interface
The Outcome: Zero Recalls, 93% Less Waste and Full Compliance
In the 12 months since deploying 6 Fanchi-tech Bulk X-ray Inspection Systems across NutriGrain’s Italian production facilities:
- 48 Critical Contamination Incidents Intercepted: Detected 0.3-1.0mm metal, glass, stone, and bone contaminants in bulk products, preventing 4 potential recalls and 120000 EUR+ in estimated recall costs.
- 93% Reduction in False Rejects: Weekly bulk product waste dropped from 3.2 tons to 224kg, saving 4400 EUR monthly in material and labor costs.
- 30% Faster Production: Eliminating manual re-inspection increased line efficiency by 30%, adding 12 hours of weekly production capacity during peak harvest seasons.
- 100% Audit Compliance: Passed all EFSA and BRCGS audits with zero non-conformities, securing a 5-year contract extension with its largest European retail partner.
- 40% Lower Maintenance Costs: Modular, industrial-grade design reduced annual maintenance expenses by 40% compared to legacy systems.
The Fanchi-tech bulk X-ray system didn’t just solve our contamination problems—it transformed our bulk processing operations, said Rossi. We now have complete confidence that every batch of nuts and grains leaving our facility is safe, compliant, and free of harmful contaminants.
