The global grain processing and flour milling industry continues to expand steadily, driven by growth in the bakery, confectionery, and industrial food manufacturing sectors. North America and Western Europe represent mature markets with strict regulatory frameworks, while emerging markets in Southeast Asia and the Middle East are rapidly upgrading production standards. For flour millers and bulk food packagers, consistent net content accuracy is both a regulatory mandate and a critical cost control priority.
Regulatory authorities such as the FDA in the United States and EFSA in the European Union enforce strict net quantity of contents regulations for packaged food products. Under-weighed packages can result in fines, product recalls, and loss of retail distribution rights, while over-weighed packages lead to unnecessary product giveaway that erodes profit margins—an especially impactful cost for high-volume, low-margin commodities like flour. Additionally, global food safety standards including HACCP, BRCGS, and IFS Food require automated process control and documented quality verification at critical production points.
Traditional manual weighing and sampling methods are incompatible with modern high-speed bagging lines, which can produce 30+ 25kg bags per minute. This operational gap has accelerated demand for robust, heavy-duty dynamic checkweigher solutions built for continuous industrial operation and seamless integration with bulk packaging systems.
This case study features a regional flour milling company based in northern Germany, specializing in industrial-grade wheat flour packaged in 25kg woven polypropylene bags. The customer supplies bulk flour to large-scale bakeries, pasta manufacturers, and food processing plants across Northern Europe, running two production lines 16 hours per day, six days per week.
Prior to implementing automated checkweighing, the customer relied on manual batch weighing: operators would pull one bag every 20 minutes for static scale verification. This approach created three core challenges:
The customer also faced space constraints on the production floor and required a solution that could integrate directly with their existing automatic bagging and sealing equipment without major line reconfiguration.
Manual and semi-manual weight control methods have fundamental limitations that make them unsuitable for modern bulk flour packaging operations:
For bulk commodity products like flour, even a small reduction in giveaway can deliver rapid return on investment. Many millers find that automated inline checkweigher systems pay for themselves within 12–18 months through reduced product loss alone.
After evaluating multiple suppliers, the customer selected the Shanghai Fanchi-tech FA-CW600 Heavy-Duty Dynamic Checkweigher as their inline weight control solution. The FA-CW600 is engineered specifically for medium-to-heavy packaged products up to 50kg, making it ideal for 25kg flour bag applications.
The FA-CW600 also features a 7-inch LCD touchscreen interface with intuitive multilingual controls, 100-product memory for quick formula switching, and built-in self-diagnostic functions for reduced downtime.
The FA-CW600 was configured specifically to match the customer’s 25kg flour bag production parameters:
This tailored configuration ensures the system operates at peak accuracy and reliability within the customer’s specific production environment.
The FA-CW600 checkweigher is integrated into the end-of-line packaging workflow as follows:
All weight data is logged by the system and can be exported via USB or optional Ethernet connection for quality reporting and compliance documentation.
Six months after installation, the customer reported measurable improvements across operational, financial, and compliance metrics:
The customer also noted that the system’s self-diagnostic features and robust industrial design have resulted in >99.5% uptime, with no unplanned downtime related to the checkweigher in the first six months of operation.
Shanghai Fanchi-tech Machinery Co., Ltd. is a specialized manufacturer of industrial inspection and weighing equipment with over 14 years of experience serving the global food processing and packaging industry.
Q: What is the maximum weight capacity of the FA-CW600 heavy-duty checkweigher? A: The FA-CW600 has a weighing range of 0.1kg to 50kg, making it suitable for a wide range of medium and heavy packaged products including 25kg and 50kg bulk bags.
Q: How fast can the FA-CW600 inspect 25kg flour bags? A: The system supports a maximum inspection speed of 35 pieces per minute, which covers most standard industrial bagging line speeds for 25kg bulk products.
Q: What type of reject mechanism does this checkweigher use? A: The FA-CW600 is equipped with a heavy-duty pneumatic pusher rejector, designed to reliably divert heavy bags up to 50kg without tipping or product damage.
Q: Is the FA-CW600 checkweigher suitable for HACCP compliant food production facilities? A: Yes. The machine is constructed with 304 stainless steel and a food-grade PU anti-static belt, with a smooth, easy-to-clean design that supports HACCP and GFSI food safety requirements.
Q: How accurate is the weight measurement for 25kg bagged products? A: The FA-CW600 delivers ±10g detection accuracy within its rated weight range, providing sufficient precision for tight net content control of bulk commodity products.
Q: Can this checkweigher be integrated with our existing bagging and conveyor line? A: Yes. The system offers adjustable line height from 600mm to 900mm (customizable) and can be installed directly inline with most standard bagging and sealing equipment.
Q: How do I retrieve and analyze production weight data from the machine? A: Weight data and production reports can be exported via standard USB drive. An optional Ethernet connection is also available for real-time data integration with factory MES systems.
Q: What material is the checkweigher body made of? A: The entire machine frame and contact parts are constructed from 304 stainless steel, providing corrosion resistance and suitability for dry and damp food processing environments.
Q: What is the required air supply for the pneumatic reject system? A: The pusher rejector operates on 5 to 8 Bar (72-116 PSI) compressed air supply with a 10mm outside diameter connection.
Q: Does the checkweigher have self-diagnostic functions? A: Yes. The system includes built-in self-diagnosis for zero error, photosensor error, setting error, and products-too-close error, helping operators quickly identify and resolve issues.
