Keypack Intelligent 32-Head Combination Weigher designed for high-precision multi-recipe weighing and mixing of granular and irregular materials. It delivers X(0.5) accuracy class at 45-60 weighments per minute with independent vibration control and CAN bus modular architecture. Ideal for tea blending, coffee bean mixing, nut combinations, herbal medicine formulations, and multi-ingredient snack packaging requiring 2-in-1, 3-in-1, or 4-in-1 recipe configurations.
Product Overview
The 32-Head Combination Weigher represents the pinnacle of multi-recipe weighing technology, specifically engineered for applications requiring precise blending and mixing of multiple ingredient types in predetermined ratios. With 32 independent weighing heads, this advanced system dramatically increases the number of possible weight combinations, resulting in superior accuracy and consistency compared to standard multihead weighers with fewer heads.
The Keypack Intelligent (Kunbupack) 32-head multihead weigher features partitioned feeding hoppers and independent main vibrators that enable simultaneous handling of 2, 3, or 4 different material types with individual flow control for each ingredient. This unique capability makes it the ideal solution for manufacturers producing blended products such as trail mixes, herbal tea blends, coffee blends, mixed nuts, seasoning mixes, and multi-component recipes where precise ratio control is critical for product consistency and quality.
Built with high-precision custom sensors and intelligent stabilization algorithms, this combination scale ensures accurate weighing performance across diverse product densities and particle characteristics. The reinforced integrated chassis design with aluminum shell hopper structure enhances machine rigidity, reduces hopper stabilization time, and improves long-term accuracy. The modular CAN bus architecture with Modbus industrial protocol integration enables seamless communication with packaging equipment for unified control and real-time production monitoring.
The automatic weight compensation feature intelligently adjusts the final ingredient to achieve target total weight, ensuring consistent blend ratios even when individual ingredient weights vary slightly. This advanced functionality minimizes product giveaway, reduces waste, and maintains strict quality control standards essential for food safety compliance and brand consistency.
Key Features and Machine Characteristics
Multi-Recipe Weighing Capability
2-in-1, 3-in-1, 4-in-1 Recipe Configurations: Supports simultaneous weighing and mixing of 2, 3, or 4 different ingredient types in precise predetermined ratios. This flexibility enables manufacturers to produce diverse product portfolios including trail mixes, herbal blends, coffee blends, seasoning mixes, and multi-component snack packages without equipment changeover, maximizing production efficiency and reducing downtime.
Automatic Weight Compensation: Intelligent compensation algorithm automatically adjusts the final ingredient quantity to achieve exact target total weight, compensating for minor variations in earlier ingredient doses. This advanced feature ensures consistent blend ratios, minimizes product giveaway, and maintains strict quality control standards across all production batches.
32 Weighing Heads for Maximum Combinations: With 32 independent weighing heads, the system generates exponentially more possible weight combinations compared to standard 10-head or 14-head weighers. This increased combination probability directly translates to superior weighing accuracy, reduced standard deviation, and minimized product giveaway, improving profit margins on high-volume production runs.
Advanced Control and Integration
High-Precision Custom Sensors: Equipped with specially manufactured high-precision, high-standard load cells engineered to deliver consistent X(0.5) accuracy class performance across varying product densities, particle sizes, and environmental conditions. These precision sensors ensure reliable weight measurements essential for regulatory compliance, quality assurance, and customer satisfaction in food and pharmaceutical applications.
Intelligent Fault Alarm System: Proactive diagnostic monitoring with intelligent fault detection and alarm prompts enables predictive maintenance, minimizes unplanned downtime, and simplifies troubleshooting for maintenance personnel. Clear error messages with specific fault codes reduce mean time to repair and help operators quickly identify and resolve issues before they impact production.
CAN Bus Modular Architecture: High-integration modular design utilizing CAN (Controller Area Network) bus technology provides faster data transmission between weighing heads, improved system reliability, and simplified troubleshooting. The distributed control architecture reduces wiring complexity, enables real-time communication for synchronized operation, and facilitates future upgrades and expansions.
Modbus Industrial Protocol Integration: Implements Modbus industrial standard communication protocol to achieve unified interface control between the combination weigher and packaging machine. This seamless integration eliminates the need for separate control panels, streamlines operator training, reduces production floor footprint, and enables centralized monitoring of the complete packaging line from a single touchscreen interface.
10.1-Inch Touchscreen Interface: Intuitive touchscreen HMI provides easy access to all weighing parameters, recipe management, real-time production data, and diagnostic information. Operators can quickly switch between recipes, adjust individual ingredient flow rates, monitor performance metrics, and access historical data for quality assurance and process optimization.
Mechanical Excellence for Multi-Material Handling
Partitioned Feeding Hoppers: Features separated feeding hopper design specifically engineered for multi-recipe applications, with independent compartments for each ingredient type. This partitioned configuration prevents cross-contamination between ingredients, maintains product purity, and enables precise individual flow control essential for consistent blend ratios and allergen management.
Independent Main Vibrators: Each ingredient compartment is equipped with its own dedicated main vibrator with independent control, allowing operators to fine-tune feeding intensity and material flow rate for each ingredient type based on its unique flow characteristics, bulk density, and particle size. This individual control capability ensures optimal feeding performance across diverse material types simultaneously.
Reinforced Integrated Chassis Design: One-piece integrated chassis and center seat construction significantly enhances machine rigidity and structural stability. This robust design minimizes vibration transmission between weighing heads, reduces hopper stabilization time for faster weighing cycles, and maintains long-term dimensional accuracy even under continuous high-speed operation.
Aluminum Shell Hopper Structure: Stable aluminum shell hopper construction provides superior vibration damping and thermal stability compared to traditional designs. This advanced structure ensures more stable hopper operation, faster signal stabilization, more accurate weight readings, and improved repeatability across all 32 weighing heads.
High-Speed Asynchronous Discharge: Advanced asynchronous discharge functionality prevents material accumulation and blockage in discharge chutes, maintaining consistent throughput even when handling multiple ingredient types with different flow characteristics. This feature is particularly valuable for sticky materials, fragile products, or ingredients with significantly different bulk densities.
Standardized Modular Design: Unified design standards with precision mold manufacturing processes ensure excellent interchangeability of components across all weighing heads. This standardization simplifies spare parts inventory management, reduces maintenance complexity, and enables faster component replacement during routine maintenance or repairs.
Stepper Motor Drive System: Precision stepper motor drive provides accurate, repeatable hopper door operation with minimal maintenance requirements. The stepper motor system ensures consistent discharge timing across all 32 heads, contributes to overall weighing accuracy, and delivers reliable long-term performance.
