The Granule Weighing & Packing Machine provides accurate weight-based portioning for free-flowing granular solids. Engineered for flexible batch production, this system replaces volumetric measurement with load-cell precision, discharging preset quantities directly into bags, rigid containers, or pouches positioned by the operator.
Key Features of Semi Automatic Granule Weighing & Filling Machine
Load-Cell Precision: Replaces volumetric cups with measured weight control to eliminate batch density variations.
Flexible Batch Switching: Adjusts target weights via the digital control panel without changing mechanical parts.
Streamlined Manual Workflow: Requires operator intervention only for container placement and removal, maintaining steady throughput.
Accessible Sanitation: Open-frame hopper and discharge chute design allow rapid clean-down between material runs.

Main Components
Weighing System
Digital load cells and control board calculate target mass in real time before releasing the material.
Supply Hopper
Top-mounted stainless steel holding bin maintains consistent material gravity feed to the weighing tray.
Discharge Chute
Funneled outlet directs weighed granules cleanly into the open container neck.
Operator Interface
Keypad interface stores target weights, tolerance thresholds, and calibration parameters.
Material Compatibility
Particle Structure: Suitable for dry, free-flowing granules including rice, seeds, grain, plastic pellets, and animal feed.
Flow Characterization: Requires non-cohesive solids that pass through gravity or vibratory feeders without bridging.
Pre-Order Material Testing: Sample verification confirms bulk density, particle size distribution, and angle of repose to establish exact speed and accuracy tolerances.
Typical Applications
Grain & Seed Packaging
Fills retail bags and seed packets with consistent net-weight portions.
Animal Feed Processing
Portions dry kibble, pellets, and crushed feed supplements into pre-formed pouches.
Industrial Granule Handling
Handles plastic resin pellets, chemical granules, and desiccants for commercial packaging lines.
System Configuration Steps
Specify Target Weight: Define minimum, nominal, and maximum filling ranges per container.
Determine Target Output: Provide required containers-per-hour targets to match feeder trough sizing.
Verify Material Profile: Supply bulk density (g/cm³), particle size, and moisture content data.
Match Packaging Specs: Share container height, mouth inner diameter, and bag type to finalize chute geometry.
Quality Control & Delivery Inspection
Electrical Safety Audit
Standard voltage tolerance, earthing, and control loop verification prior to factory acceptance.
Static & Dynamic Calibration
Multi-point calibration using certified weights across the entire 50–5,000 g spectrum.
Live Material Trial
Factory testing using actual product samples to verify discharge speed and cutoff accuracy.

FAQ
Q: What types of products suit this machine?
A: Free-flowing, non-stick dry granules such as seeds, grains, feed pellets, and small industrial plastic parts.
Q: How is the target weight adjusted?
A: Target weights are set directly on the digital control interface without requiring mechanical component changes.
Q: What factors determine the actual filling speed?
A: Speed depends on target dose weight, bulk density, particle flow characteristics, and operator handling rhythm.
Q: Is this system fully automated?
A: No. This is a semi-automatic unit requiring an operator to place and remove containers, while the machine handles weighing and dosing.
Q: Can contact parts be customized for specific hygienic standards?
A: Yes. Product contact surfaces can be fabricated according to specific application demands.
