Bottom line: pick the filling principle (gravity, pump, piston, or specialized) from your viscosity and container, then validate accuracy, cleaning, and line integration.
Step 1 — Classify by Viscosity and Particles
- Water-like liquids → gravity or pump
- Viscous sauces/pastes → piston or positive-displacement pump
- Liquids with chunks → piston or specialized rotor pump
Step 2 — Confirm Fill Volume Range and Accuracy
Small doses (e.g., 5–100 ml) prioritize dosing stability; larger fills prioritize throughput and anti-drip control. Ask for tolerance at your target volume.
Step 3 — Match Container Type
| Container | Typical solution |
|---|---|
| Bottles/jars | Inline filler + capper; piston/pump/gravity depending on viscosity |
| Pouches/sachets | Pouch/sachet packing machine + liquid dosing module |
| Foamy or delicate liquids | Nozzle design + bottom-up fill + anti-foam strategy |
Step 4 — Hygiene, Temperature, and Cleaning
- Food-grade materials (SUS304/316)
- CIP-friendly piping, quick disassembly
- Hot-fill temperature and seal material compatibility

Inputs we need for an accurate quotation
- Product state and behavior (powder flowability, viscosity, particulates, temperature)
- Package format and size range (bag/bottle/jar; material and seal type)
- Fill range and target tolerance (e.g., 100–500 g, ±1–2 g)
- Target output (units/min or hr) and expected runtime per day
- Local utilities (voltage/phase/frequency, compressed air, clean-room/hygiene level)
- Photos or sample pack + label requirements (if any)
Common failure points (what usually goes wrong)
- Filler choice not matching product behavior (bridging, foaming, shear sensitivity)
- Poor dust control contaminating seals (powders)
- Unstable feeding causing speed fluctuations and weight drift
- Bag material/seal spec not compatible with sealing temperature or contamination
- Underestimating footprint and maintenance access space
Factory acceptance test (FAT) checklist
- Run with your product or a confirmed substitute and record output stability
- Check weight accuracy vs tolerance at different speeds
- Verify sealing integrity (leak test / visual inspection) across a full shift simulation
- Confirm safety, emergency stop, guards, and basic alarms
- Capture test video and final configuration list for handover
Frequently Asked Questions
What filler is suitable for carbonated beverages?
Carbonated drinks typically require counter-pressure filling to control CO₂ loss and foaming. Share your beverage specs and bottle type to confirm the correct system.
Can the same machine fill both water and cooking oil?
Often yes within a compatible viscosity range, but cleaning and changeover procedures matter. Tell us the products and hygiene requirements for confirmation.
What accuracy can I expect?
Accuracy depends on filler type, product behavior, and volume. Piston/positive-displacement systems are typically the most stable for viscous products.
Do you support hot-fill?
Yes. Specify your filling temperature and packaging materials so sealing and component selection can be matched properly.
