Product Overview

This universal cup metering machine utilizes precision volumetric cup measuring technology to achieve accurate dispensing of granular and powdered materials across diverse food processing, chemical manufacturing, and pharmaceutical packaging applications. The system operates through a hopper feeding mechanism that delivers material into calibrated measuring cups, which are then discharged via mechanical or pneumatic drive systems to provide consistent volumetric portions. The adjustable cup volume design enables rapid changeovers between different fill sizes without requiring complete equipment replacement, making it a versatile volumetric metering equipment solution for multi-product facilities.

Manufactured by Keypack Intelligent (Kunbupack), this granular material metering device represents a cost-effective and eco-friendly powder metering solution for businesses requiring reliable volumetric dispensing without the complexity and expense of electronic weighing systems. The simple mechanical structure comprises a material hopper, precision cup measuring unit, automated drive system, and control panel, ensuring easy operation, minimal maintenance requirements, and stable long-term performance. This design philosophy makes the equipment particularly suitable for cereal metering machine applications, grain processing operations, and food ingredient packaging where volumetric accuracy is sufficient and gravimetric precision is not required.

The machine's operational principle centers on volumetric displacement through calibrated measuring cups that fill with material from the overhead hopper and discharge precise portions through mechanical rotation or pneumatic actuation. The cup volume can be adjusted by changing cup inserts or modifying the fill level to accommodate different product densities, particle sizes, and target weights. This flexibility enables the equipment to handle materials ranging from fine powders like flour and sugar to coarse granules like cereal, nuts, and pet food kibble, supporting granule powder mixing metering applications where multiple ingredients require proportional dispensing.

The control system provides adjustable parameters for fill speed, discharge timing, and cycle sequencing to optimize performance for specific material characteristics and packaging line requirements. The automated operation reduces labor requirements and ensures consistent fill volumes across production runs, while the simple mechanical design minimizes electrical components and reduces energy consumption compared to electronic weighing systems. This eco-friendly powder metering approach supports sustainable manufacturing practices by eliminating the need for load cells, complex electronics, and high power consumption associated with combination weighers and checkweighers.

With three model options covering volumetric ranges from 50-800ml (KB-LB800) to 500-6000ml (KB-LB6000) and metering speeds from 20-50 fills per minute, this high-efficiency cup metering equipment balances throughput with versatility for small to large-scale packaging operations. The compact footprint and lightweight construction (80-180kg) enable flexible installation in space-constrained production areas, while the standardized design supports integration with various bag-making machines, pre-made pouch fillers, bottle filling lines, and container packaging systems.
