EW220 High-Precision Inline Checkweigher: Reliable Weight Compliance for Small Food, Cosmetic & Pharmaceutical Packages
For manufacturers of small packaged products including snack sachets, candy bars, cosmetic samples and pharmaceutical blister packs, net weight control directly determines brand reputation and profit margin. Underweight packages trigger consumer complaints, retail penalties and regulatory fines, while overfilled products cause persistent raw material waste and erode gross margins. Manual random sampling cannot achieve 100% full inspection, and low-end weighing equipment suffers from unstable accuracy and frequent false rejection, which cannot meet the requirements of modern high-speed production lines.
Shanghai Fanchi-tech Machinery Co., Ltd. launches the EW220 high-precision conveyor checkweigher, tailor-made for small and medium-sized finished package weight re-inspection. As shown in the factory real-shot photos, the machine adopts a fully food-grade 304 stainless steel structure, high-precision load cell sensing system, transparent safety protection cover and automatic pneumatic rejection mechanism, which can be seamlessly connected to various packaging lines. It has become the preferred quality control equipment for hundreds of food, daily chemical and pharmaceutical factories in Europe, Southeast Asia and the Middle East.
Core Structural Advantages
All designs are verified by actual production and delivery, and are completely consistent with the equipment received by customers:
1. Full 304 Stainless Steel Curved-Leg Frame, Food-Grade Sanitary Standard
The whole machine body, conveyor bracket and support legs adopt integrated bending and seamless welding process of 304 food-grade stainless steel, with no sharp edges and hidden sanitary dead corners. The smooth brushed surface is resistant to corrosion of cleaning agents and food grease, supports daily water washing and disinfection, and fully complies with HACCP, FDA and GMP food hygiene and safety standards.
The curved leg design avoids dust and residue accumulation at the bottom, and is equipped with adjustable anti-vibration leveling feet, which can stably fix the equipment on the workshop ground and filter the vibration interference of upstream equipment on weighing accuracy.
2. Side-Mounted Touch Control Cabinet, Intuitive & Efficient Operation
The independent vertical control box is installed on the side of the weighing section, equipped with a 7-inch industrial color touch screen and a prominent red emergency stop button, which is convenient for operators to set parameters and deal with emergencies in time. The multi-language system supports English, Spanish, French, Russian, etc., and can store up to 100 groups of product formulas. One-click switching of different SKUs greatly shortens the line changeover time.
The sealed electrical cabinet has good dust and splash resistance, and is suitable for production workshops with regular cleaning needs. The built-in data storage module supports USB and Ethernet export of weighing records, providing complete audit data for retailer supplier audits and third-party quality inspections.
3. Transparent Acrylic Safety Guard, Visual Operation & High Safety
A fully enclosed high-transparency acrylic protective cover is installed above the weighing and rejection section, which allows operators to observe the product conveying and weighing status in real time without opening the cover. At the same time, it prevents foreign objects from falling into the weighing area and avoids accidental contact with moving parts by operators, effectively improving operation safety and weighing stability.
4. High-Precision Weighing System + Pneumatic Push-Rod Rejector
Built-in high-stability precision load cell, with minimum resolution up to 0.01g, which can stably capture tiny weight deviations. The intelligent anti-vibration algorithm filters environmental interference, maintaining high accuracy even under high-speed operation.
Equipped with a pneumatic push-rod automatic rejection mechanism, when overweight or underweight products are detected, the push rod smoothly pushes unqualified products into the locked rejection bin without stopping the main production line. The thrust can be adjusted flexibly, which will not damage fragile packaging such as blister boxes and soft sachets.
5. Adjustable Guide Baffles, Compatible With Multi-Size Products
Adjustable limit guide baffles are installed on both sides of the conveyor belt to keep products centered during transportation, avoid weighing errors caused by product offset, and adapt to packages of different widths and shapes. The food-grade white PU conveyor belt is anti-static, oil-resistant and wear-resistant, which is easy to disassemble and clean, and will not scratch or contaminate product packaging.

Real Customer Success Case: Polish Confectionery Manufacturer Achieves Zero Weight Complaints
Client Profile
SweetDelight Sp. z o.o., a well-known confectionery manufacturer located in Warsaw, Poland, mainly produces hard candy, chocolate bars and jelly sachets, supplying large supermarket chains and convenience stores across Poland and Eastern Europe, with 6 high-speed automatic packaging lines.
Core Pain Points Before Cooperation
- High complaint risk: Only 8% of products were manually sampled every hour. Underweight candy bags flowed into the market from time to time, resulting in 4-6 consumer complaints per month and 2 formal rectification notices from supermarkets.
- Serious raw material waste: To avoid underweight risks, workers increased the filling volume as a whole, with an average overfilling rate of 2.8%, resulting in an annual raw material loss of about 320,000 PLN.
- Low efficiency of manual sorting: When unqualified products were found in sampling, manual sorting was required, which interrupted continuous production and increased labor costs.
Fanchi-tech Customized Solution
After remote line investigation and actual product weighing test, we provided 5 sets of EW220 high-precision checkweighers, which were installed at the end of the packaging lines for full online weight re-inspection. We set independent weight tolerance standards for different candy products, connected the automatic rejection function, and completed equipment debugging, operator training and regular after-sales follow-up.
Quantifiable Results After 6 Months of Operation
- 100% full inspection, zero weight complaints: All finished products are inspected one by one, and unqualified products are automatically rejected. Since the equipment was put into use, no weight-related consumer complaints or supermarket penalties have occurred.
- 92% reduction in overfilling waste: The overfilling rate dropped from 2.8% to 0.22%, saving about 294,000 PLN in raw material costs every year, and the investment cost was recovered within 8 months.
- Improved production efficiency: Automatic weighing and rejection replaced manual sampling and sorting, freeing 4 front-line operators to take charge of other work, and the overall operating efficiency of the production line increased by 27%.
- Smoothly passed supermarket audit: The complete data recording function meets the retailer’s traceability requirements, helping the customer successfully pass the annual supplier quality audit and obtain two new long-term supply contracts.
“The EW220 checkweigher runs very stably. It can accurately detect even a weight difference of 0.1g, and the false rejection rate is extremely low. It not only solves our weight compliance problem, but also saves a lot of raw material costs for us. The after-sales service of Fanchi-tech team is also very professional and timely.”
