5 Gallon Water Filling Line

The main body of the machine has a rectangular structure with adjustable feet at the base to regulate height and maintain level balance. Inside, it integrates three

systems — rinsing, filling, and capping — allowing all operations to occur within a single unit.

Each position on the conveyor chain is equipped with a photoelectric sensor paired with pneumatic cylinders for precise bottle control. The lower section houses the electrical control cabinet for safe and efficient operation.

This machine is primarily used for producing PC-barreled water. By using a neck-hanging design, it shortens material contact with the external environment, improving hygiene, productivity, and overall economic efficiency.

The cap sorting and feeding system uses a belt-driven cap delivery mechanism that can be adjusted to accommodate different cap heights. The arc-shaped guide rail ensures each cap falls precisely onto the bottle mouth, aligning perfectly with the fully automatic track-type capping machine.

This equipment offers simple, rational structure and high automation. It eliminates the need for manual cap feeding, making operation convenient and efficient.

Additionally, the system includes an online cap cleaning and disinfection feature, which automates the entire process. Each cap undergoes thorough washing and sterilization, minimizing contamination risks. This technology also contributes to energy efficiency and environmental protection.

The barreled water film cutting and cap removing integrated machine is made of high-quality SUS304 stainless steel, ensuring durability and hygiene. The film cutting system cleanly removes the film without damaging the bottle mouth and includes a film collection device.

It uses a two-piece cap removing head with high stability and efficiency. The machine features a kick-out function for unremoved caps — when a cap is not fully detached, it automatically detects and removes the bottle from the conveyor, preventing jams in later stages.

Equipped with an advanced automation control system, the machine enables fast and continuous operation, improving efficiency and reducing labor costs. Its precise mechanical design ensures accurate film cutting and cap removal, while the easy-to-clean structure simplifies maintenance and lowers overall costs.

In this stage, empty barrels are conveyed into the brushing system, where they are automatically counted and positioned. Pneumatic devices push the barrels into rotating brush stations, where internal and external brushes work simultaneously.

The main rotary brushes and inner brushes move in opposite directions, ensuring a deep and thorough cleaning of the barrel’s body, inner and outer walls, neck, and bottom. Continuous water or detergent spraying keeps the brushes clean, and the collected water is recycled back into the cleaning tank.

The system features central, side, and bottom brushes for full-coverage cleaning. Compact structure, high automation, and elegant design make it an ideal solution for exterior barrel cleaning.

The LED light inspection box uses high-intensity LED sources and imported light-diffusing plates to provide even illumination without dark zones or flicker. It is designed for inspecting the clarity, turbidity, color, and leaks in transparent bottled liquids.

After capping, each filled bottle passes through this inspection station, where operators visually check for suspended solids, sediment, or other impurities. Unqualified products are manually removed to ensure that only clean, clear water moves to the next process.

This process uses a steam heat shrink system. The water tank connects directly to the finished water pipeline, with an electronic float-level controller regulating water levels. Electric heaters raise the water temperature until it reaches 140–170°C at 2–4 atmospheres of pressure, ready for shrinking operations.

When barrels pass under the steam distribution hood, directed steam jets heat the neck area, perfectly shrinking the plastic film around it.

Machine Features:

•  Atmospheric safety design for reliable pressure control.

•  Concentrated heat flow ensures perfect shrinkage without deformation.

•  Easy maintenance, energy saving, and durable construction.

•  Provides excellent cleanliness, sealing, and moisture resistance.

Finally, the filled barrels are transferred via the conveyor to the automatic bagging system. A sensor detects barrel position and triggers automatic bag cutting and sealing, producing tightly wrapped, hygienic packages with a uniform, professional appearance.

This machine supports continuous operation, dramatically improving packaging efficiency. Its precise positioning system ensures each barrel is neatly bagged.

The stainless-steel frame and linear design provide durability, easy cleaning, and a modern aesthetic. The system is adjustable for different barrel sizes, offering high flexibility for varied production needs.

These integrated machines together form a 5 gallon water filling line that ensures a continuous, sanitary, and fully automated process—from barrel cleaning to final packaging—making it ideal for large-scale drinking water manufacturers.

The water filling production line by MIC Machinery combines technology, automation, and customization. It can be tailored to fit the specific needs of mineral water, purified water, or alkaline water production.

Key highlights:

•  Compatible with barrel sizes from 3 to 5 gallons.

•  Adjustable filling speeds to match production volume.

•  Integration with labeling, film wrapping, and palletizing equipment.

•  Compact layout that optimizes floor space.

Whether you operate a small bottling plant or a large industrial facility, MIC’s water filling production line ensures maximum output with minimal human labor.

MIC’s water production line is not limited to 5-gallon operations—it also supports smaller bottles, PET containers, and various cap styles. The company designs modular systems that can easily expand into a fully automated beverage factory, connecting water purification units, labeling, packaging, and palletizing systems into one integrated network.

With over a decade of manufacturing experience, MIC provides turnkey water production line projects that improve efficiency, reduce energy consumption, and enhance product quality.
