Granule Weighing Machine - 2 Head Linear Scale

Keypack Intelligent Belt-Type Linear Weighing Scale is a precision viscous material weighing equipment designed for accurate quantitative dosing of sticky and fluffy materials. It delivers 20-12000g weighing range with X(1) accuracy and 10-30 bags/min speed through automatic belt speed control and CAN bus communication technology. Ideal for vegetable salad packaging, fruit salad portioning, fresh vegetable weighing, and sticky material dosing in food processing operations.

Product Overview

This linear weighing scale operates through a belt-type feeding system specifically engineered for handling sticky, fluffy, and irregular materials that challenge conventional weighing equipment. The system features a human-machine interface with 7-inch touch screen for quick retrieval of preset weighing parameters across different weight ranges, enabling rapid changeover between vegetable salads, fruit salads, and various sticky material applications.

The controller and AD conversion module communicate via CAN bus technology, ensuring the weighing process is independently managed by the AD module board for enhanced precision and reliability. This advanced communication protocol delivers stable weight readings and reduces electronic interference in food processing environments, making it a dependable vegetable weighing machine for commercial operations.

The output port function adopts a free port design, allowing signal output customization based on operational requirements. The system includes signal testing functionality for simplified troubleshooting and equipment maintenance, reducing downtime in production environments. Detailed production record statistics enable real-time performance monitoring and quality control for sticky material dosing operations.

The belt-type feeding configuration enhances material flowability, making this viscous material weighing equipment suitable for various fluffy and adhesive materials including leafy vegetables, salad mixes, and sticky granular products. The variable speed motor automatically adjusts belt speed during the weighing process, enabling dynamic speed optimization from fast bulk feeding to slow precision dosing as target weight approaches.

A pneumatic gate at the belt feeder outlet enables precise small-flow feeding control, effectively improving weighing accuracy for sticky materials prone to clumping or bridging. All material contact components utilize patterned plate construction, reducing contact surface area with sticky materials and effectively controlling material adhesion issues common in vegetable and salad weighing applications.

Key Features and Machine Characteristics

The controller and AD conversion module communicate through CAN bus technology, with the weighing process independently managed by the AD module board for superior accuracy. This advanced communication architecture ensures stable weight readings and minimizes electronic interference, delivering reliable performance as a grain weighing machine and powder weighing device for food processing operations requiring consistent dosing accuracy.

Free Port Output Design with Signal Testing

The output port function adopts a flexible free port design, allowing signal output customization to match downstream packaging equipment and production line requirements. The integrated signal testing functionality simplifies troubleshooting and fault diagnosis, reducing maintenance time and improving equipment uptime in commercial food processing environments.

Detailed Production Record Statistics

The system tracks comprehensive production data including total weighments, average weights, deviation statistics, and throughput rates. This production monitoring capability supports quality control initiatives, helps identify weighing inconsistencies, and provides documentation for food safety compliance in vegetable and salad packaging operations.

Belt-Type Feeding for Improved Material Flow

The belt-type feeding system enhances material flowability compared to vibratory feeders, making it particularly effective for fluffy and sticky materials including leafy vegetables, salad mixes, and adhesive granular products. This gentle handling approach reduces material damage while maintaining consistent feeding rates, supporting quality preservation in fresh produce weighing applications.

Automatic Speed Control with Variable Speed Motor

The variable speed motor automatically adjusts belt speed during the weighing cycle, implementing fast feeding for bulk material transfer and slow precision feeding as target weight approaches. This dynamic speed optimization improves weighing accuracy while maintaining throughput, making it an efficient vegetable weighing machine for commercial salad packaging and fresh produce portioning operations.

Pneumatic Gate for Precision Feeding Control

The pneumatic gate at the belt feeder outlet enables precise small-flow feeding control during final weight approach, effectively improving weighing accuracy for sticky materials prone to clumping. This precision feeding mechanism reduces weight overshoot and minimizes product giveaway, supporting cost control in high-value vegetable and salad packaging applications.

Patterned Plate Construction for Adhesion Control

All material contact components utilize patterned plate construction, reducing contact surface area with sticky materials and effectively controlling material adhesion issues. This anti-stick design feature ensures consistent material discharge from weighing buckets and feeding chutes, maintaining reliable operation across production runs with various sticky and adhesive materials.
