As global demand for seasoning powders continues to grow, manufacturers are under increasing pressure to deliver consistent package weights while reducing production costs. Whether supplying supermarket private labels, foodservice distributors, or seasoning brands, maintaining accurate net weight has become just as important as ensuring product quality.
For lightweight products such as 10g, 20g, 50g and 100g seasoning powder sachets, even a deviation of 0.3–0.5g can lead to significant product giveaway or underweight packages. This directly impacts production costs, customer satisfaction, and compliance with international regulations.
To address these challenges, one Southeast Asian seasoning manufacturer upgraded its packaging line with a Fanchi High-Precision Dynamic Checkweigher, achieving higher production efficiency, improved weight consistency, and reduced product waste.
The customer is a professional seasoning manufacturer supplying OEM and private-label products to supermarkets and food companies in Europe, the Middle East, and Southeast Asia.
Their main products include:
The factory operates two fully automatic packaging lines producing approximately 100–120 pouches per minute.
Typical package sizes include:
| Product | Package Weight |
|---|---|
| Chicken Powder | 10 g |
| Garlic Powder | 20 g |
| Curry Powder | 50 g |
| BBQ Seasoning | 80 g |
| Mixed Spice | 100 g |
| Soup Powder | 200 g |
These lightweight products fall perfectly within the optimal weighing range of the Fanchi Dynamic Checkweigher (3–300 g).
Although the customer had already invested in modern auger filling machines, several issues remained.
The seasoning powders had different bulk densities and flow characteristics. During long production runs, vibration, humidity, and material settling caused slight variations in filling accuracy.
As a result, package weights gradually drifted outside the customer’s preferred tolerance.
To prevent underweight complaints, operators intentionally increased the filling target.
For example:
Target Weight
50 g
Actual Filling
50.8–51.2 g
This meant every package contained approximately 0.8–1.2 g of unnecessary product.
Although almost invisible on a single pouch, the accumulated loss became substantial over millions of packages.
The factory estimated that thousands of kilograms of seasoning powder were being given away every year.
Previously, quality inspectors randomly checked package weight every 30 minutes.
This meant that hundreds or even thousands of pouches could pass through the line before a filling issue was discovered.
Several European customers required documented evidence that every production batch complied with declared net weight.
Manual inspection records were no longer sufficient to satisfy modern food safety audits.
After reviewing the customer’s production line, Fanchi engineers proposed installing a compact high-precision dynamic checkweigher immediately after the VFFS packaging machine and before the metal detector.
This location allows every finished pouch to be weighed automatically before entering the final quality inspection stage.
The compact footprint fit perfectly into the customer’s existing production line without requiring major modifications.
Unlike large-package checkweighers designed for cartons or bags weighing several kilograms, this model is specifically engineered for lightweight flexible pouches.
Its weighing platform and conveyor dimensions are optimized for products between 3 g and 300 g, making it particularly suitable for seasoning powder packaging.
The system combines high weighing accuracy with high-speed operation, allowing manufacturers to inspect every pouch without reducing production throughput.
Once each pouch leaves the vertical packaging machine, it enters the Fanchi checkweigher.
The infeed conveyor automatically separates each pouch, ensuring stable weighing conditions.
Even lightweight 10 g sachets remain properly aligned while travelling along the conveyor.
Each pouch passes smoothly across the precision weighing platform.
Within milliseconds, the high-speed load cell measures the exact package weight.
The intelligent controller compares the measured weight with the preset target value and acceptable tolerance.
For example:
Target Weight:
50.0 g
Acceptable Range:
49.7–50.3 g
Every package is inspected individually without stopping production.
If a pouch falls outside the specified weight range, the controller immediately sends a reject signal.
Depending on the customer’s production requirements, the system can be equipped with:
Only qualified products continue to the metal detector and final packing station.
During production, the touchscreen continuously displays:
This data helps quality managers monitor production performance in real time.
Within several weeks of operation, the customer reported measurable improvements.
By tightening filling control, average product giveaway was reduced by approximately 26%.
This generated significant annual savings in seasoning powder consumption.
More than 99.5% of finished pouches remained within the customer’s specified tolerance.
Automatic inspection eliminated the risk of underweight products reaching customers.
Operators no longer needed to interrupt production for frequent manual sampling.
Quality inspection became fully automated.
Electronic production records simplified customer audits and supported export documentation requirements.
Modern seasoning production requires more than accurate filling.
Manufacturers increasingly demand complete inline inspection solutions that improve efficiency while ensuring food safety.
Fanchi provides integrated inspection systems including:
These systems can be customized according to production speed, product size, and factory layout.
The Fanchi Dynamic Checkweigher is ideal for lightweight packaged food products, including:
Recommended Product Weight: 3 g – 300 g
