1. Bottle Washing System
Built into the 3-in-1 monobloc isobaric filler, the bottle washing system delivers full interior rinsing with minimal handling and contamination risk.
Empty PET bottles feed into the washing station via air conveyor, where positive-transfer grippers move them smoothly through the cycle without scratching bottle surfaces. A neck-gripping wash dial secures each bottle by the neck and rotates 180° along the guide track, angling the bottle opening downward to drain completely during cleaning. Inside the dedicated wash zone, precision-machined spray nozzles deliver targeted rinsing across every inch of the inner bottle wall, removing residual dust and contaminants before filling.
Once rinsed and fully drained, the dial rotates bottles 180° back to an upright, stable position. Clean bottles exit the wash station and transfer directly to the filling station via the same positive-gripper transfer system, keeping handling consistent and reducing unnecessary bottle transfers.
2. Isobaric Filling System
At the core of the machine is the isobaric filling system, engineered specifically for carbonated beverages to preserve consistent CO₂ content and eliminate foaming, overflow and product waste.
As bottles enter the filling station, bell jars center each bottle precisely before a lifting cylinder raises it to form a tight, leak-proof seal against the filling valve. A bottle presence sensor mounted on the infeed steel thumb wheel sends real-time signals to the PLC control system, activating the no-bottle-no-filling function to avoid wasted product and unnecessary valve wear.
Filling initiates automatically only once the gas pressure inside the bottle matches the pressure in the filling tank — the core of the isobaric filling principle. The fill cycle stops immediately and automatically the moment liquid reaches the air return pipe height, delivering consistent, repeatable fill level accuracy across every bottle. Once filling is complete, the valve shutoff mechanism seals the filling valve, followed by controlled pressure release inside the bottle to finish the full fill cycle without foaming or spillage.
3. Screw Capping System
The integrated screw capping system delivers consistent, torque-accurate capping without damaging caps or bottle necks, keeping carbonation locked in through shelf life.
Filled bottles move directly to the capping station for automatic screw sealing. A press-down cam lowers each bottle gently off the filling valve, and transitional positive grippers transfer it to the capping turret without jostling or spilling. A bladed bottle stop locks each bottle neck securely, holding it upright and preventing rotation during the tightening process for uniform torque every time.
Each screw capping head on the turret combines orbital revolution and independent rotation, working sequentially to pick, place, tighten and release caps in one smooth, continuous motion. A cap sorter sits above the capping station, feeding caps through a sliding guide rail to the capper’s cap hopper for steady, uninterrupted cap supply even at full running speed. Finished bottles transfer to the output conveyor via the outlet thumb wheel, exiting the isobaric filler smoothly to feed downstream processes like labeling or packaging.
