Keypack Intelligent Leak-Proof Multihead Weigher - Precise Weighing for Small Granules

Keypack Intelligent Leak-Proof Multihead Weigher is a high-precision combination scale designed for accurate quantitative weighing of small granular materials. It delivers leak-proof performance with high-precision custom sensors and IP65 waterproof protection, featuring multi-stage weight calibration and independent vibration amplitude control for stable feeding. Ideal for salt weighing, sugar weighing, coffee bean packaging, seed portioning, and MSG/chicken essence quantitative filling across food processing, seasoning production, and agricultural packaging lines.

Product Overview

This leak-proof multihead weigher combines advanced weighing technology with robust mechanical design to meet the demanding requirements of small granule packaging operations. The system utilizes high-precision custom sensors specifically engineered for accurate measurement of free-flowing granular materials, while the IP65 waterproof chassis ensures reliable operation in food processing environments where moisture and dust are present.

The weigher's intelligent control system supports 100 parameter preset configurations, enabling rapid changeover between different products and target weights without extensive recalibration. Each vibratory feeder line features independent amplitude adjustment during operation, ensuring uniform material distribution and consistent weighing accuracy across all weighing heads. The automatic pause function activates when material levels are insufficient, preventing inaccurate weighing cycles and maintaining product quality standards.

Manufactured by Keypack Intelligent (Kunbupack), this combination scale represents a cost-effective solution for businesses requiring precise quantitative weighing with leak-proof reliability. The 60-degree discharge chute angle facilitates smooth material flow, minimizing product retention and enabling clean transitions between batches. The cast aluminum thickened integral middle base enhances structural rigidity, reducing vibration-induced measurement errors and shortening stabilization time for faster cycle rates.

The multihead weigher's global-ready design includes multi-language interface options and comprehensive help menus, making it accessible to operators worldwide. The forward and reverse adjustable rotating main vibrator ensures materials enter the linear vibratory pans uniformly, regardless of particle size variations or flow characteristics. Checkered plate construction on all product-contact surfaces provides durability and easy cleaning, supporting food safety compliance and GMP requirements.

Specifications

Key Features and Machine Characteristics

• High-Precision Custom Sensors: Specially designed high-precision sensors deliver accurate weight measurement for small granular materials, ensuring consistent portion control and minimizing product giveaway. The high-standard sensor technology maintains accuracy even with challenging materials like sticky sugar crystals or irregularly shaped seeds, supporting tight tolerance requirements in regulated food and seasoning industries.
• Leak-Proof IP65 Waterproof Design: IP65-rated waterproof chassis protects electrical components from moisture, dust, and material spillage common in food processing environments. This leak-proof construction prevents product contamination, reduces maintenance requirements, and extends equipment lifespan in humid production facilities, making it ideal for sugar weighing, salt packaging, and other hygroscopic material applications.
• Multi-Stage Weight Calibration System: Advanced calibration functionality supports multi-stage weight calibration and factory parameter recovery, enabling precise accuracy across different weight ranges and material densities. Operators can quickly restore optimal settings after maintenance or recalibrate for new products, reducing downtime and ensuring measurement consistency throughout production runs.
• Independent Vibration Amplitude Control: Each vibratory feeder line features independent amplitude adjustment during operation, allowing real-time optimization of material flow for uniform feeding. This feature is critical for handling materials with varying flow characteristics—from free-flowing coffee beans to cohesive chicken essence granules—ensuring consistent weighing performance without stopping production for mechanical adjustments.
• Automatic Material Shortage Detection: Intelligent monitoring system automatically pauses weighing operations when material levels are insufficient, preventing inaccurate short-weight packages and maintaining quality control standards. This feature reduces product waste, protects brand reputation, and ensures compliance with weight accuracy regulations in food packaging operations.
• 100 Parameter Preset Storage: Store up to 100 complete parameter configurations for different products, target weights, and packaging formats, enabling rapid product changeovers without manual recalibration. This multi-recipe capability is essential for contract packagers and multi-product facilities handling salt, sugar, seeds, spices, and other small granules on the same production line.
• Global Multi-Language Interface: Comprehensive multi-language support with integrated help menus makes the weigher accessible to international operators and simplifies training requirements. The user-friendly interface reduces operator errors, accelerates learning curves, and supports global deployment across multiple production facilities.
• Extended Material Length Capacity: Accommodates materials up to 300mm in length, providing versatility for elongated granules, seed varieties, and specialty products beyond standard spherical or cubic particles. This extended capacity expands application possibilities to include long-grain rice, sunflower seeds, and other non-standard granular materials.
• Optimized 60-Degree Discharge Chute: Steep 60-degree discharge angle ensures smooth, complete material flow from weighing buckets to packaging containers, minimizing product retention and enabling clean batch transitions. This design feature is particularly valuable for sticky materials like brown sugar or coated seeds, reducing cross-contamination risks and simplifying cleaning procedures.
• Drying and Dewatering Protection: Equipped with drying and dewatering device that effectively prevents electrical component damage in humid environments, extending equipment reliability in tropical climates or high-moisture production areas. This protection system is essential for facilities processing hygroscopic materials like salt and sugar that generate moisture during handling.
• Reinforced Cast Aluminum Construction: Thickened cast aluminum integral middle base enhances structural strength and vibration damping, reducing weighing stabilization time and enabling faster cycle rates. The robust construction maintains measurement accuracy under continuous high-speed operation, supporting productivity targets in demanding production environments.
• Food-Grade Checkered Plate Contact Surfaces: All material-contact components utilize checkered plate construction for durability, easy cleaning, and compliance with food safety standards. The textured surface prevents material buildup while maintaining smooth flow, supporting sanitation requirements and reducing contamination risks in food and seasoning packaging operations.
