Overview

Creative's Automatic Servo Auger Powder Filling Machine is engineered for precise dosing of non-free-flowing powders, fine chemicals, nutraceutical granules, and pharmaceutical formulations. Powered by a high-resolution servo drive and an independent slow-speed stirring blade, it delivers exceptional repeatability, zero compaction degradation, and clean bottle neck cutoff.

Servo Motor Screw Drive: Micro-step rotation control enables exact powder dosing angle and volume repeatability.
Separate Stirrer Motor: Continuously rotating agitator blade ensures constant powder head density around the auger screw.
Split Hopper Design: Hinged or quick-release stainless steel hopper opens horizontally for quick washdowns and screw swaps.
No Bottle – No Fill Sensor: Infrared fiber-optic gating prevents auger rotation if a container is misaligned or missing.
Anti-Drip Shut-Off Funnels: Pneumatically operated cut-off flaps or centrifugal discs prevent trailing powder after cycle completion.
Integrated Dust Extraction Collar: Vacuum shroud ring connected to external dust collector prevents ambient airborne particles.

Servo Volumetric & Gravimetric Dosing Architecture
1. Precision CNC Machined Auger Screws:

Custom-pitched SS 316L auger flights polished to mirror finish (< 0.4 µm Ra) guarantee non-stick transfer, zero shear degradation, and uniform volumetric displacement.

2. Dynamic Feedback Loop (In-line Load Cell):

Optional real-time weight feedback connects downstream checkweigher to the auger servo PLC. The system dynamically adjusts the pulse count of upcoming fills to counteract powder density variations.

3. Independent Slow-Speed Agitation:

Driven by a separate gear motor, the agitator paddle sweeps hopper walls to prevent tunneling, rat-holing, and aeration, maintaining consistent bulk density above the auger intake.

4. Container Centering & Pneumatic Vibration:

Pneumatic lift-and-settle mechanism vibrates containers during filling, allowing fluffy powders to de-aerate and settle deeply inside narrow-neck bottles.

  • Automatic Vacuum / Screw Powder Loader: Senses hopper level and automatically conveys powder from ground drum to hopper.
  • Checkweigher with Air-Jet Rejector: Rejects underweight/overweight bottles inline and auto-corrects auger revolutions.
  • Laminar Airflow / Nitrogen Flushing Hood: Enclosure preserving sterile conditions and protecting hygroscopic powders from oxidation.
  • Container Lifting & Vibration Device: Lifts bottle mouth over funnel to prevent dust emission and vibrates bottle base to compact airy powders.
  • 21 CFR Part 11 Software Suite: Touchscreen audit trails, electronic signatures, password management, and production batch logs.

Frequently Asked Questions

A rotary vacuum dry syrup machine uses vacuum pressure ports inside a wheel cavity to dose light, free-flowing dry antibiotic powders into small bottles at high speeds. An auger filler uses a precision servo-driven screw, making it suitable for both free-flowing and sticky, non-free-flowing powders, fine chemicals, protein powders, and larger fill weights (5g to 1kg+).

Yes. Changing the dosing range is achieved by replacing the auger screw and corresponding funnel tooling. Small-diameter screws provide exact resolution for 5g–50g, while larger-pitch screws accommodate 100g–1000g containers with short fill cycle times. Tooling swaps take under 15 minutes.

The machine utilizes positive cut-off nozzles (pneumatic flap / spinner plate) that snap shut instantly after rotation stops. In addition, an integrated suction ring collar connects to a dust extractor to pull loose dust particles directly from the bottle mouth before exit.

We provide full regulatory validation documentation including Design Qualification (DQ), Installation Qualification (IQ), Operational Qualification (OQ), Performance Qualification (PQ), SS 316L mill test certificates, calibration reports, and FAT/SAT verification protocols.
