Overview


The 6000bph Aluminum Bottle Carbonated Drink Filling Machine is a high-speed, precision-engineered solution designed for the efficient packaging of carbonated soft drinks (CSD), seltzer water, sparkling juices, and other effervescent beverages into aluminum bottles. Engineered to maintain the integrity of carbonation and prevent oxygen ingress, this machine combines advanced isobaric filling technology with automatic cap sealing, ensuring zero foam loss and consistent fill levels for 125ml to 1L aluminum containers. With a production capacity of 6,000 bottles per hour (bph), it caters to large-scale beverage producers, craft soda manufacturers, and premium drink brands seeking a balance of speed, hygiene, and packaging versatility. The system supports both recyclable aluminum and composite aluminum-plastic bottles, adapting to cylindrical, slim, or sport-shaped designs with minimal changeover time.


Features


1. Isobaric Filling Technology: Utilizes a two-step pressure equalization process (CO₂ pre-pressurization at 2-4 bar and constant-pressure filling) to preserve carbonation levels (up to 8g/L CO₂) and eliminate foaming, critical for maintaining the effervescence and mouthfeel of sparkling beverages.

2. Aluminum Bottle Specific Design: Customized gripper arms and neck guides accommodate the lightweight, thin-walled nature of aluminum bottles (wall thickness: 0.3-1.0mm), preventing deformation during transport and sealing. The filling nozzle features a retractable design to avoid contact with the bottle rim, reducing contamination risks.

3. Precision Cap Sealing: Equipped with a servo-driven roll-on pilfer-proof (ROPP) capping head that applies aluminum or composite caps with torque control (3-8N·m), ensuring airtight seals and tamper evidence. An integrated vision system verifies cap alignment and tightness, with automatic rejection of mis-sealed bottles.

4. Hygienic Construction: Wetted components are constructed from food-grade 316L stainless steel with electropolished surfaces (Ra ≤ 0.8μm), while the frame uses corrosion-resistant 304 stainless steel for easy washdown. A HEPA-filtered air curtain protects the filling zone from external particulates, maintaining ISO Class 8 cleanliness.

5. Adaptive Speed Control: Servo motors and variable frequency drives (VFDs) enable smooth speed adjustments from 2000 to 6000 bph without compromising filling accuracy (±1.5ml for 330ml bottles). Quick-release star wheels and conveyor rails allow bottle size changeovers in <20 minutes.

6. Energy-Efficient Pneumatics: A CO₂ recirculation system reduces gas consumption by 30% compared to traditional systems, while low-power servo motors minimize electrical usage. The machine includes an idle-mode function that reduces energy draw during temporary stops.


Applications


Carbonated Soft Drinks: Processes cola, lemon-lime soda, and fruit-flavored sparkling drinks for global beverage brands and private label producers.

Premium Sparkling Water: Fills flavored seltzer, alkaline water, and luxury sparkling water in sleek aluminum bottles for retail and on-premise consumption.

Sparkling Juices & CSDs: Handles low-sugar, all-natural sparkling juices and craft sodas, preserving the vibrant color and effervescence of premium formulations.

Functional Beverages: Suitable for energy drinks, electrolyte water, and probiotic sparkling beverages, with optional nitrogen blanketing to protect sensitive ingredients.


FAQ


Q: Can this machine handle non-carbonated beverages in aluminum bottles?

A:Yes, it can be switched to gravity filling mode for still drinks by disabling the CO₂ pre-pressurization system. Contact our team for custom nozzle configurations.

Q: What is the minimum/maximum bottle diameter the machine can process?

A:It handles bottle diameters from 50mm (slim 200ml) to 90mm (1L sport bottles). Custom gripper sets are available for non-standard shapes, such as hexagonal or oval bottles.

Q: How does the machine prevent aluminum bottle scratching during handling?

A:All contact surfaces (star wheels, guides) are coated with food-grade silicone to minimize friction, and the conveyor speed is synchronized with bottle rotation to eliminate sliding.

Q: What maintenance is required for the capping head?

A:Routine maintenance includes weekly torque calibration and monthly inspection of capping rollers for wear. A spare parts kit with replacement seals and bearings is included for quick swaps.

Q: Is the machine compatible with inline carbonation systems?

A:Yes, it integrates seamlessly with upstream carbonators and gas mixing units via a pressure-stabilized buffer tank. Our engineers provide full system integration support for turnkey solutions.
