FA-CW Series Checkweigher: Precision Weight Control for Snack & Nutraceutical Packaging
For manufacturers of snack foods, nutraceuticals, and small-packaged consumer goods, accurate weight control is critical to meeting regulatory standards, reducing material waste, and protecting brand reputation. Even minor underfills or overfills can lead to costly penalties, customer complaints, and eroded market trust. SnackJoy Global, a leading producer of premium nut mixes and protein bars in the Netherlands, turned to Shanghai Fanchi-tech Machinery Co., Ltd. to solve its weight inspection challenges. By deploying our CW Series Checkweigher, SnackJoy eliminated weight variation risks, cut waste, and secured long-term compliance with EU food safety regulations.
The Challenge: Weight Inconsistency & Production Bottlenecks in Small Packaging
SnackJoy Global produces over 120,000 small-packaged items daily, including 50g nut mix pouches, 35g protein bars, and 100g herbal supplement sachets. In early 2025, a batch of 50g nut mix pouches was found to have an average underfill of 1.5g, triggering a warning from the Dutch Food and Consumer Product Safety Authority (NVWA) and a temporary production suspension. The company’s legacy checkweighing system exposed critical flaws:
- Insufficient Precision: The old checkweigher had a measurement tolerance of ±2g, failing to detect the 1.5g underfill in small 50g pouches, which violated EU Regulation (EU) 2019/1020 on weighing and measuring instruments.
- Unstable Conveying: Small, lightweight pouches frequently shifted or tipped on the old system’s narrow belt, leading to a 11% false reject rate—wasting 13,200 qualified items weekly.
- Slow SKU Switching: Manual calibration between different product formats (pouches, bars, sachets) slowed production by 23% during peak demand periods.
- Hygiene Gaps: The old machine’s crevice-ridden design trapped food residues, creating bacterial growth risks and failing BRCGS audits.
“Our small-packaged snacks are our core product line, but weight inconsistency and production inefficiencies were threatening our business,” says Emma van der Zee, Quality Director at SnackJoy Global. “We needed a precise, stable checkweigher built to handle diverse small-packaged formats without compromising speed or hygiene.”
The Solution: Fanchi-tech CW Series Checkweigher for Small Packaging
After evaluating 7 competitors, SnackJoy selected the CW Series Checkweigher for its high precision, stable conveying, and hygienic design. As shown in our factory photos, the CW Series features a 304 stainless steel frame, three-stage white conveyor belt (infeed, weighing, outfeed), touch-screen control panel, emergency stop button, and pneumatic reject mechanism—all engineered for small-packaged food and nutraceutical production lines.
1. Ultra-High Precision for Small Packages
The CW Series uses high-precision load cells and advanced signal processing to deliver measurement accuracy of ±0.1g, even for 35g protein bars and 50g pouches. Key capabilities:
- Underfill/Overfill Detection: Identifies deviations as small as 0.5g in small packages, ensuring full compliance with EU weight labeling regulations.
- High-Speed Operation: Processes up to 180 packages per minute, matching SnackJoy’s packaging line speed.
- Adaptive Calibration: Automatically adjusts to different package sizes and materials (plastic, paper, aluminum), eliminating manual calibration between SKUs.
During on-site validation, the CW Series detected 100% of test underfill and overfill conditions in 50g nut mix pouches, 35g protein bars, and 100g supplement sachets.
2. Stable Conveying for Small, Lightweight Packages
The CW Series’ three-stage conveyor system and adjustable guide rails are designed to handle small, lightweight packages without shifting or tipping:
- Smooth Belt & Guide Rails: Prevents packages from moving during weighing, ensuring consistent positioning and accurate readings.
- Gentle Reject Mechanism: Pneumatic reject arms gently remove non-conforming packages from the line without damage, reducing waste by 32%.
- Adjustable Height: Accommodates packages of varying heights, from thin protein bars to bulky nut mix pouches.
3. Hygienic Design & Intelligent Operation
The CW Series’ crevice-free 304 stainless steel construction supports daily high-pressure washdowns, while its food-grade white belt resists food residue buildup. Key features:
- Easy-to-Clean Surfaces: Seamless stainless steel surfaces eliminate hidden crevices, reducing cleaning time by 38% and minimizing bacterial growth risks.
- Fast SKU Switching: The touch-screen control panel stores 50+ product presets, enabling SKU switching in 15 seconds—down from 18 minutes with manual calibration.
- Audit-Ready Traceability: Logs 1,000,000+ weight records, including time-stamps and batch numbers, for BRCGS and regulatory audits.
The Outcome: Zero Regulatory Warnings & 21% Faster Production
In the 10 months since deploying 6 CW Series Checkweighers:
- 54 Critical Underfill/Overfill Incidents Intercepted: Detected deviations as small as 0.5g in small packages, preventing 3 potential regulatory warnings and €68,000 in estimated recall costs.
- 93% Reduction in False Rejects: Weekly package waste dropped from 13,200 to 924, saving €2,100 monthly in material and labor costs.
- 21% Faster Production: Fast SKU switching and stable conveying increased line efficiency, adding 12 hours of weekly capacity during peak holiday demand.
- 100% Audit Compliance: Passed all BRCGS and NVWA inspections with zero non-conformities, securing a 5-year contract extension with its largest European retail partner.
“The CW Series didn’t just fix our weight control problem—it transformed our small-packaging operations,” says van der Zee. “We now have complete confidence that every package leaving our facility is accurate, compliant, and safe for consumers.”
