What bottling machine is needed for 300 bottles per hour?

For a target output of 300 bottles per hour, you typically need a compact, fully automatic bottled water filling line with a rated capacity of 200–500 bottles/hour (based on 18.9 L or 5-gallon bottles), integrated with a dual-membrane NF + UF or two-stage RO purification system, PLC-based control, and an automated bottle washing-filling-capping unit. This configuration balances throughput, water quality stability, and operational simplicity for small to mid-scale production.

Core Specifications to Verify

• Rated Capacity: Ensure the machine is rated for at least 300 bottles/hour under your specific bottle size and water viscosity. Chuxin Mingwei’s standard lines cover 200–1,800 bottles/hour for 18.9 L bottles, with customization available.
• Filling Accuracy: Look for ≤ ±2 mL deviation to minimize product loss and ensure label compliance.
• Capping Pass Rate: ≥99.6% is standard for reliable sealing without manual rework.
• Purification Process: Match the water treatment to your source. Spring water often uses NF + UF to retain minerals, while purified water requires two-stage RO with ozone and UV sterilization.

Facility & Operational Readiness

Before installation, confirm your facility can support the line’s footprint, power supply (typically 380V/50Hz), compressed air, and drainage. Cleanroom compliance (ISO Class 8 or higher) is recommended for food-grade or pharmaceutical applications. Airflow, pressure zoning, and HEPA filtration should be engineered to your layout to prevent cross-contamination.

Implementation Boundaries & Risk Notes

Equipment performance depends on consistent source water quality, proper operator training, and routine maintenance. Long-term shutdowns require flushing, disinfection, or protective storage per membrane and equipment guidelines. Ozone and UV sterilization serve different purposes and cannot be used interchangeably; their combination must be validated against your water chemistry and production schedule.
