Introduction
A rotary filling machine is the workhorse of high-throughput production lines, seamlessly combining precision, speed, and flexibility to handle everything from thin liquids to viscous creams. By continuously moving containers through integrated rinsing, filling, and capping stations arranged around a central turret, rotary fillers deliver unparalleled output—often exceeding 2,000 to 20,000 bottles per hour—while occupying a remarkably compact footprint.

How It Works
1. Container Indexing
* Empty bottles are fed onto a rotary star wheel or conveyor.
* Each container is precisely positioned in a pocket on the rotating turret.
2. Rinsing/Pre&Treatment (Optional)
* An integrated bottle washer sprays purified air or liquid to remove dust and debris.
* Ensures hygienic filling for beverages, pharmaceuticals, and cosmetics.
3. Auger or Piston Filling
* As the turret advances, each container pauses briefly under a stationary filling head.
* Volumetric augers or piston pumps accurately meter out the exact dosage—whether water, paste, or gel.
4. Capping and Sealing
* Immediately after filling, bottles move to an automatic capper.
* Torque-controlled heads apply screw or snap caps, guaranteeing leak-proof seals every time.
5. Discharge
* Finished, fully sealed containers exit the turret onto an outfeed conveyor, ready for labeling, packing, or inspection.

Key Advantages
* High Speed & Throughput: Parallel filling heads enable rates from 2,000 to 20,000 bottles per hour or more.
* Space Efficiency: Multiple process stations share a single rotating axis, minimizing floor space.
* Product Flexibility: Quick-change format parts allow rapid retooling for different bottle sizes and fill volumes.
* Integrated Hygiene: In-line rinsing and CIP options support stringent food and pharmaceutical standards.
* Precision & Consistency: Closed-loop control systems ensure uniform fill volumes, reducing giveaway.
