5 Gallon Water Bottle Filling Machine

The fully automatic 5-gallon water bottle filling machine developed and manufactured by Qingzhou Foren Water Treatment Equipment Co., Ltd. is a core, integrated system for bottled drinking water production. Designed specifically for 5-gallon (18.9L) PC bottles, this equipment combines external and internal bottle washing, disinfection, quantitative filling, and cap placement/pressing into a single unit. Constructed entirely from food-grade 304 stainless steel, it meets the production line requirements of both small-to-medium and large-scale water plants. It handles the entire process-from empty bottle processing to capping the finished product-in one continuous operation, significantly reducing manual intervention and minimizing the risk of secondary contamination. The system can operate as a standalone unit or be integrated with RO pure water equipment, ETP wastewater treatment systems, and palletizing mechanisms to form a complete water plant facility.

The machine features an integrated, unitary frame structure welded from food-grade 304 stainless steel plate. It is resistant to water and corrosion from acidic or alkaline disinfectants, fully complying with hygiene standards in the food and beverage industry.

 

 

Operational workflow:

Empty bottle loading → Bottle mouth pre-rinsing → Internal alkaline washing/disinfectant spraying → High-pressure fresh water rinsing (internal and external) → Drip drying → Quantitative filling with sterile water → Automatic cap feeding and cap washing → Cap pressing and sealing → Finished bottle discharge.

 

01

 

Washing Unit

Features a multi-station circulating spray structure that utilizes disinfectant and purified water in separate stages to thoroughly remove dirt and algae from the inner walls of used barrels. It maintains stable spray pressure and ensures centralized collection and discharge of wastewater.

 

02

 

Filling Unit

Employs a gravity or flow-meter-based quantitative filling method. It uses stainless steel aseptic filling valves with precise, controllable fill levels and a drip-proof design to prevent overflow and equipment contamination.

 

03

 

Capping Unit

Features automatic cap sorting and placement with adjustable pressing force. It is compatible with tamper-evident caps designed for 5-gallon PC barrels, effectively eliminating issues such as loose or slipping caps. The machine is equipped with transparent safety glass windows for real-time monitoring of internal operations. It utilizes top-tier pneumatic components, water pumps, and pressure gauges, and features an independent electrical control system with variable frequency drive (VFD) capabilities for adjustable production speeds. The number of stations can be customized to meet specific needs, with production capacities ranging from 200 to 800 barrels per hour.

1. Production facilities for bottled purified water, mineral water, and mountain spring water; specifically for filling 5-gallon PC barrels.
2. Suitable for new water plants, production line upgrades for existing plants, and scenarios involving the recycling and refilling of used barrels.
3. Can be integrated with RO (Reverse Osmosis) purification systems, raw water pretreatment systems, industrial wastewater treatment equipment (ETP), external barrel washers, and automatic palletizers to create a comprehensive, one-stop bottled water production line.
4. Can also be used for filling other low-viscosity bottled beverages, such as sparkling water or selenium-enriched water (requires a customized solution). Product

1. Hygienic and Safe Design: Constructed entirely from food-grade 304 stainless steel; all water-contact components are designed without dead zones to facilitate CIP (Clean-in-Place) sanitization. This effectively minimizes the risk of bacterial contamination in bottled water and complies with drinking water production standards.
2. Integrated System with Compact Footprint: Barrel washing, filling, and capping are consolidated into a single main unit. Compared to modular setups, this eliminates the need for inter-machine conveyors, saves factory floor space, and simplifies installation and commissioning.
3. Compatible with New and Recycled Barrels: Features a multi-stage spray washing process designed to eliminate stains and microorganisms from recycled barrels; offers strong compatibility with standard PC barrels, including those with slight deformations.
4. Stable Performance and Low Failure Rate: Utilizes core pneumatic and pump components from renowned international and domestic brands. Variable frequency drive (VFD) ensures smooth operation, while easy-to-replace wear parts keep long-term maintenance costs low.
5. Flexible Customization: Workstations and supporting solutions can be tailored to the client's facility layout, target production capacity, and water quality conditions. Qingzhou Foren provides comprehensive engineering services, including equipment manufacturing, on-site installation and commissioning, operator training, and after-sales maintenance.
6. Energy-Efficient and Eco-Friendly: Employs a recirculating water system to minimize water waste; wastewater can be connected to an ETP (Effluent Treatment Plant) system to ensure discharge compliance with local environmental regulations.
