5 gallon filling machine

Name: 5 gallon filling machine
SKU: 0

The QGF series filling machine is designed for filling 3-gallon and 5-gallon water barrels, suitable for producing purified water, mineral water, and other bottled drinking water.
Constructed from food-grade 304 stainless steel, the machine features pneumatic filling and offers a choice of multiple filling heads. It operates reliably and is easy to maintain; it can function as a standalone unit or be integrated with barrel-washing and capping equipment to form a fully automated production line, making it suitable for water plants of all sizes.

Product Value

Wide production capacity range

Multiple models available with capacities ranging from 150 to 1,500 barrels per hour, suitable for large, medium, and small-scale bottled water plants to meet various production requirements.

Hygienic and reliable

Constructed from food-grade 304 stainless steel and utilizing pneumatic filling to prevent secondary contamination, ensuring compliance with hygiene standards for drinking water production.

Flexible configuration

Can operate as a standalone unit or integrate with external barrel washers and high-pressure rinsing machines to form a complete, automated bottled water production line.

Low operating and maintenance costs

Features a mature design with a low failure rate; allows for easy barrel-type switching and convenient daily cleaning and maintenance.

Applicability boundaries

Applicable container types

3-gallon and 5-gallon PC large containers (standard size: Φ270×490mm)

Applicable products

Still drinking water (e.g., purified water, mineral water, mountain spring water)

Not suitable for

Carbonated beverages, high-viscosity liquids, or non-standard/irregularly shaped large containers

Working Principle

A compressed-air-driven pneumatic valve assembly executes the filling process: once an empty drum is in position, the filling head descends to seal against the drum opening, the filling valve opens, and quantitative filling is achieved via the liquid level difference.

Upon completion of filling, the valve assembly closes and the filling head retracts; the drum is then transferred to the next stage of the process.

Core components

Filling head assembly

Controls water inlet flow; makes direct contact with the product; made of 304 stainless steel.

Pneumatic control valve assembly

Manages the lifting of the filling head and the opening/closing of valves.

Main machine frame

Structural support frame for the entire unit; made of 304 stainless steel.

Conveying mechanism

Positions and conveys large drums; ensures precise alignment between the drum opening and the filling head.

Optional

In-line cap disinfection equipment

Sanitizes and cleans caps for improved hygiene.

Automatic cap sorting and feeding mechanism

Automatically sorts and feeds caps with a low-stock alarm, eliminating the need for manual cap loading.

Changeover/Cleaning/Maintenance

Format Changeover

Container opening remains constant while height or diameter changes; no replacement of filling heads or cup-pressing tools is required, though mechanical adjustments and parameter updates are necessary, along with synchronized adjustments to auxiliary equipment across the line.

Cleaning

Perform CIP (Clean-in-Place) circulation cleaning on filling heads and fluid lines at the end of each production day;Disassemble filling head components, rinse with clean water and food-grade disinfectant, and allow to air-dry;

Maintenance

Pneumatic components: Regularly inspect and service cylinders and solenoid valves; check for air leaks

Seals

Regularly inspect filling head seals; replace promptly if signs of aging or wear appear.

How do I switch formats if the barrel opening diameter remains the same but the barrel height or body diameter differs?



There is no need to replace the filling head. Instead, adjust the height of the filling crossbeam, the conveyor guardrails, and the workstation positioning stops; modify the cylinder stroke and filling parameters; and make corresponding adjustments to upstream and downstream equipment, such as barrel washers and capping machines.

What are the daily cleaning and maintenance requirements?



At the end of each production day, perform CIP (Clean-in-Place) cleaning or disassemble and rinse the filling heads and piping; regularly drain accumulated water from the air supply system; periodically replace sealing rings; and tighten screws on the conveyor assembly.

Can the equipment operate as a standalone unit?



Yes. It can function as a standalone filling unit or be integrated with barrel washers, capping machines, and conveyor lines to form a fully automated bottled water production line.

Which materials are unsuitable for filling with this equipment?



It is suitable only for still drinking water, such as purified water and mineral water; it is not suitable for carbonated beverages, high-viscosity liquids, or highly corrosive liquids.
