Line parameters
About the solution
The main task of a returnable-container line is not filling but guaranteed sanitation: the bottle comes back from the field, so the cycle includes an external brush, removal of the old cap, internal brush washing, three stages of washing with detergent and disinfectant solution, and a final rinse with finished product.
After filling, the bottle passes through a light inspection, a tamper-evident cap is fitted and shrunk on, the date is applied, and the container moves to the palletiser. The process is fully enclosed, eliminating secondary contamination.
Built into the design
Automatic decapping
The old cap is removed by the machine — the operator never touches the neck of the returned container.
Internal and external brush washing
Rotating brushes remove biofilm and scale that jet rinsing alone cannot clear.
Multi-stage washing
Alkaline solution, disinfectant and final rinse with finished product, in separate recirculating loops.
Tamper seal and traceability
Heat-shrink cap seal and batch coding confirm the bottle was not opened after filling.
Line composition along the product flow
8 positions along the product flow. Every unit opens in the catalog: series, specifications, scope of supply and a quote request.

Line process flow
A 3-5 gallon returnable bottle line works with a multi-use container: each cycle includes receiving empty containers, double washing (external and internal), filling and inspection before shipment.
Key features of the gallon bottle line
- Double washing: external brush wash and internal high-pressure wash with caustic, disinfectant and ozonated water
- Every bottle is checked for cracks, deformation and foreign odor before washing
- A wash-fill-cap triblock in an enclosed zone reduces the risk of secondary contamination
- Caps are fed and washed with disinfectant and ozonated water before capping
- The filled bottle is inspected on a light box before labeling
- A heat-shrink neck band guarantees tamper evidence for the end consumer
- Optional connection to a shop-floor accounting and remote monitoring system
Standard layout for reusable PC/PET bottles with a full washing cycle.

Key line stations
What sits behind the nameplate output: contact-part execution, operating logic and service points for every station.
Water treatment station
Process-grade water
- Mechanical and carbon filtration, softening, reverse osmosis — the scheme is built from the raw-water analysis.
- Membranes with a flush system and VFD pump start: longer membrane life, no water hammer.
- UV and ozone disinfection, storage tank in AISI 316.
- Station capacity sized with a 20% margin over the line's peak demand.

Core machines of the line
Equipment of the “19-Litre Bottle Water Filling Line” layout: each tile opens the catalog with series, specifications and a quote request for that machine.

Bottle depalletizer
Layer-by-layer removal of empty returnable containers from the pallet and feeding onto the conveyor without manual labor.

Decapper
Automatically removes the old cap from the 55 mm neck and diverts it to a waste bin.

Leak and odor inspector
Checks bottles for cracks, deformation and foreign odor — unsuitable containers are rejected before washing.

External brush washer
Rotating brushes on the body, shoulders and base, plus a warm-water shower: removes dust and transport residue.

High-pressure washer
Internal treatment by station: alkaline wash, disinfectant, rinse with product-grade water and steam nozzle sterilization.

3-in-1 triblock
Washing, gravity filling of 18.9 L and cap press-fitting in an enclosed zone on a single frame.

Labeler and coder
Applies a body label and prints the filling date, shift number and expiration date.

Tamper-evident cap sleeving
Fits a thermal cap over the neck and shrinks it in a heat tunnel — guarantees a first-open seal.

Palletizer
Forms rows, stacks them layer by layer on a pallet, and hands off to stretch wrapping.
Which closure do you use
The cap type defines the capping block: heads, feeding and orientation of the closure, torque or press-on force. State your option in the request and we will select the head and sorter for it.
55 mm (smart cap)
Cap for 5-gallon (19 L) bottle
Press-fit onto the neck collar, with a shrink tamper-evident band applied over it.
Capping unit: Press head with shrink-seal band

FAQ
How many wash stages are enough?
For returnable containers we always specify at least three: alkaline wash, disinfection and a rinse with finished product. Cutting stages quickly turns into microbiology complaints.
Can the line handle both new and returnable containers?
Yes, the line is designed with a bypass: new containers go through a shortened rinse cycle, returnable ones go through the full cycle.
How much does the 19-Litre Bottle Water Filling Line cost?
Price on request: the budget depends on output, container type, line composition and the level of automation. After a short brief we send a preliminary estimate within 1–2 working days and a full quotation broken down by machine within 3–5 days.
What are the delivery and commissioning lead times?
Standard machines ship 8–12 weeks after the specification is confirmed, complete lines 12–20 weeks. Transport takes 2–6 weeks depending on the route; installation and commissioning on site take 2–4 weeks, with operator training included.
What output does this line reach?
The working range is 100–1,200 bph. Exact output is confirmed against your container, product and shift plan: we calculate the line balance and keep a margin on the bottleneck machine.

Project budget
What drives the cost of a water filling line
The price is set by a combination of factors, not a single line item. We build the budget around your task and show the cost structure node by node — no hidden positions.
Output
Target bottles per hour define the machine class: from compact monoblocks to high-speed lines with automatic packaging.
Container and format
PET 0.33–1 L, PET 3–10 L, 19 L polycarbonate, glass — different tooling, capping and conveying.
Water treatment
Raw water analysis defines the train: filtration, softening, reverse osmosis, mineralisation, disinfection.
Automation level
Semi-automatic, automatic, or a line with robotic palletising and SCADA — a different budget and headcount.
End-of-line packaging
Labelling, coding, shrink wrapping, case packing, palletiser — each unit is added when it is needed.
Logistics and commissioning
Delivery, customs, supervised installation, operator training and the service package are part of the final quote.
Publishing average figures would be misleading: projects with similar output can differ several times over. Price is on request, and we quote against your actual input data.
