The semi-automatic powder filling machine provides controlled-dose filling of dry powders into pre-made bags, bottles, jars, and cans. An operator positions the container beneath the outlet, while the auger dosing system meters the targeted product quantity. This unit supports small-to-medium production batches requiring repeatable dosing precision without a fully automated packaging line.

Core Operating Process
Material Loading
Dry powder feeds into the stainless steel top hopper.
Volumetric Dosing
The vertical auger screw rotates at set increments to push measured volume through the funnel outlet.
Manual Container Positioning
The operator aligns the container opening directly below the filling nozzle.
Cycle Triggering
The operator activates the dosing turn via foot switch or optical sensor.
Material Processing Compatibility
Free-Flowing Granules
Handles coffee powder, fine sugar, salt, and coarse spices without material bridging.
Non-Free-Flowing Powders
Doses milk powder, flour, chemical powders, and starch using custom agitator blades inside the hopper.
Dust Control Units
Integrates optional dust collection shrouds to capture airborne particles at the nozzle outlet.
Dosing Range Selection Guide
Micro Dosing (1–10 g / 5–25 g): Configured with small-diameter auger screws for high-value extracts, pharmaceutical powders, and specialty chemicals.
Standard Dosing (10–50 g / 10–100 g): Standard auger profile for retail food packaging, seasoning blends, and instant drink mixes.
Bulk Dosing (25–150 g / 50–500 g): Large-pitch screw setup optimized for protein powders, agricultural chemicals, and industrial compounds.
Container Adaptability
Flexible Bags and Pouches: Accommodates stand-up pouches, gusseted bags, and flat foil sachets held manually by the operator.
Rigid Bottles and Jars: Adjusts vertically to align with glass bottles, PET jars, and aluminum canisters.
Rigid Metal Cans: Supports direct bottom-up filling for round metal tins and composite containers.
Structural Component Details
Split Hopper Design: Features a side-opening hopper for direct access during product changeovers and sanitation.
Precision Screw Drive: Driven by a dedicated step motor or servo motor to govern accurate rotation counts.
Level Sensing Unit: Triggers auto-feeding equipment when material inside the hopper drops below set thresholds.
Adjustable Platform: Height-adjustable table accommodates variable container heights.
Suitable Production Environments
Pilot Line Production
Fills short runs for market trial samples without changing main line setups.
Multi-SKU Packaging
Replaces augers quickly to switch between diverse products and package net weights.
Manual Packing Workstations
Standardizes fill accuracy across manual packaging operations.
Key Technical Parameters for Quotation
Powder Properties: Bulk density (g/cm³), particle size mesh, moisture percentage, and flow traits.
Target Package Net Weight: Specific fill weight per container and target accuracy threshold.
Container Opening Size: Internal neck diameter and total height of bags or rigid containers.
Target Throughput: Required containers per minute or target output per shift.
Fabrication and Quality Testing
Sanitary Surface Finish
Internal contact surfaces polished to Ra ≤ 0.8 µm for food compliance.
Material Certification
Contact parts constructed from certified grade 304 or 316 stainless steel.
Factory Acceptance Testing
Runs actual material samples prior to dispatch to verify dosing tolerances.
Installation and Sanitation Protocol
Requires a level bench or stand with stable power connection.
Calibration mode sets auger turn counts against target weight via digital scale feedback.
Removable auger and quick-release hopper allow full washdown without special tools.
Information Required for Inquiry

FAQ
Q: How does the machine adjust between different fill weights?
A: Operators adjust dosing weight directly on the touchscreen controller by altering auger rotation counts. Switching between wide weight ranges requires changing the auger screw size.
Q: Can dusty powders be processed without spillage?
A: Yes. An optional dust-extraction hood attaches to the filling funnel to draw excess dust away from the container neck during discharge.
Q: What filling accuracy can be achieved?
A: Volumetric accuracy reaches ±0.5 g under consistent material bulk density. For higher accuracy demands, an integrated feedback scale re-calibrates auger revolutions during production.
Q: Is specialized tooling required to clean the hopper?
A: No. Quick-release clamps allow operators to open the split hopper and remove the auger screw without external tools.
