Against the backdrop of tightening global food safety regulations and rising labor costs in the FMCG sector, accurate net content control has become a core operational challenge for packaged food manufacturers. Overfilling leads to avoidable raw material loss, while underfilling exposes brands to regulatory fines and reputational damage. Recently, Shanghai Fanchi-tech Machinery Co., Ltd. delivered a customized belt-type online checkweigher solution for a leading puffed snack manufacturer in East China. The solution enables full-process weight monitoring and automatic non-conforming product rejection on the pillow-type packaging line, delivering outstanding results in production efficiency improvement and cost optimization.
Client Challenges
The client is a specialized snack food producer with an annual output of over 12,000 tons, whose production line runs 24 hours a day in three shifts. Before cooperating with Fanchi-tech, the factory relied on manual sampling for finished product weight inspection, which brought three persistent pain points:
- Efficiency bottleneck: Manual weighing only covered 30–40 packages per minute, which could not match the 100+ packages per minute speed of the automated packaging line, restricting the overall output of the production line.
- Compliance risk: Sampling inspection failed to achieve 100% full coverage. Underweight products occasionally entered the market, resulting in consumer complaints and administrative penalties from regulatory sampling.
- High material waste: To avoid underweight risks, the production line generally set a high excess filling volume, causing about 10% of raw material waste every year and continuously eroding product profit margins.
Our Tailored Checkweigher Solution
After on-site investigation of the client’s workshop layout and in-depth communication of production requirements, Fanchi-tech deployed the FC-CW Series inline checkweigher at the back end of the client’s pillow packaging machine. The equipment adopts an all-stainless steel integrated structure, which fits the hygienic standards of food production workshops and can be seamlessly connected to the existing packaging line without large-scale transformation of the original production line.
Core configurations of the solution:
- High-precision digital load cell: Achieves ±0.5g weighing accuracy within the 5–500g range, fully adapting to the client’s 20g–300g snack package specifications.
- Automatic flip-plate rejection device: The rejection mechanism installed at the discharge end instantly removes overweight and underweight products without interrupting continuous production, with a 100% rejection accuracy rate.
- Intelligent touch control system: The 7-inch color touch screen supports one-click parameter setting, multi-product formula storage and real-time production data statistics, which is easy for on-site operators to master.
- Industrial safety design: The control cabinet is equipped with an emergency stop button and status indicator light, which meets workshop safety production standards and allows operators to respond quickly to abnormal conditions.
- Production data traceability: Supports weighing data storage and export, helping the production department count pass rate, analyze weight distribution, and optimize the filling parameters of the packaging machine.
Measurable Operation Results
After three months of stable operation, the client’s production line has achieved significant improvements in multiple dimensions:
- Zero compliance risk: 100% full weight inspection of all finished products is realized. No net content non-conformity was found in subsequent regulatory sampling inspections, effectively avoiding fines and brand reputation loss.
- Line efficiency increased by 22%: The equipment runs stably at 120 packages per minute, fully synchronized with the packaging line speed, eliminating the weighing bottleneck and increasing the overall daily output of the production line.
- Raw material waste reduced by 8%: Through precise weight data feedback, the client adjusted the filling parameters of the packaging machine and reduced the average excess filling amount. The annual raw material cost is saved by about 120,000 USD, and the investment payback period is less than 8 months.
- Labor cost optimization: 4 weighing operators per shift are reduced, and 12 labor positions are saved for three shifts a day, which also reduces the labor management cost of the workshop.
As a core product of Fanchi-tech’s weight inspection product line, the FC-CW series inline checkweigher is widely used in food, pharmaceutical, daily chemical, hardware and other industries. Its design fully fits the actual needs of industrial production scenarios:
- 304 stainless steel body with smooth surface and no sanitary dead corners, meeting food-grade sanitation standards, corrosion-resistant and durable.
- Height-adjustable support feet with rubber cushions, adapting to different workshop ground conditions and ensuring stability during high-speed weighing.
- Modular belt and rejection structure, which can be quickly disassembled for cleaning and maintenance, reducing equipment downtime.
- Diversified rejection options: flip-plate, push-rod, air-blow and other rejection methods are available for customization according to product package form and weight.
