The Role of Combination Weighers in Intelligent Packaging Systems
Combination weighers, also known as multihead weighers, are essential in modern packaging automation. With high-precision weighing, intelligent algorithms, and strong adaptability, they improve efficiency, reduce costs, and support industries like food, pharmaceuticals, and chemicals.
What is a Combination Weigher?
A combination weigher, also known as a multihead weigher, is a critical piece of equipment in industrial automation. Using 8 to 32 independent weighing units, it achieves ±0.1g precision through intelligent combination. Replacing traditional volumetric devices, it is now widely applied in the food, pharmaceutical, and chemical industries.
Core Structure and Advantages
Modern combination weighers adopt a three-layer design:
-
Upper Layer – Vibratory feeding trays evenly distribute materials.
-
Middle Layer – Weighing hoppers dynamically measure product weight.
-
Lower Layer – Material collection ensures precise discharge.
With high-precision sensors and integrated circuits, weighing speed exceeds 3 times per second. Unlike traditional platform scales with a 3–5% error rate, the combination weigher keeps errors within 0.3%. For example, a nut manufacturer reduced material loss by 12% and boosted packaging efficiency by 300% after adopting this system.
Five Major Technical Advantages
-
Intelligent Algorithm for Speed
Optimized algorithms and dynamic statistical correction enable speeds up to 200 packs per minute—3–4 times faster than traditional equipment. -
Modular Design
Quick assembly/disassembly in just 3 minutes, stainless steel parts, and flexible hopper sizes (1.6L, 2.5L, 3.0L). -
Error Prevention & Stability
Triple-verification system keeps error rates below 0.15% even after 200+ hours of continuous operation. -
Wide Material Adaptability
Capable of handling powders (≥0.5mm) to frozen products (250g), ensuring smooth processing of irregular shapes. -
Energy Efficiency
Intelligent sleep mode reduces standby energy consumption by 70%, lowering operating costs.
Industry Applications
-
Food Processing: Puffed snacks, nuts, grains, tea, coffee beans, pasta, and Chinese medicine.
-
Pharmaceutical & Healthcare: Ensures accurate dosing and safe packaging.
-
Daily Chemical & Electronics: Weighing and packing plastics, hardware, electronic parts, and components.
When integrated with a metal detector, defect interception rates exceed 98%, further ensuring product safety.
Purchasing and Maintenance Guide
When selecting a combination weigher, evaluate accuracy, speed, and certifications (CE, OIML). Leading brands such as Guangdong Kenwei Intellectualized Machinery Co., Ltd. are recognized for their precision and reliability, especially in the snack, fresh produce, meat, and pickled food industries.
For long-term performance, implement a three-tier maintenance system to reduce downtime. Additionally, consider warranty and technical support. For instance, Kenwei offers up to 2 years of extended warranty, making it a trusted choice for global manufacturers.
Future Development Trends
With the rise of Industry 4.0, combination weighers are evolving from simple weighing devices to intelligent production nodes. Key trends include:
-
AI Visual Recognition – Enhancing accuracy and adaptability.
-
Smart Integration with Multihead Weighers – Enabling seamless automation.
-
5G Connectivity – Remote diagnostics, real-time monitoring, and predictive maintenance.
Choosing the right intelligent multihead weigher solution is essential for businesses aiming to improve productivity and packaging quality.
