Bottom line: sauce filling is decided by viscosity and particles—then you pick piston or pump, and validate cleaning and anti-drip performance.
Step 1 — Classify Sauce by Viscosity and Particles
- Thin sauces (soy sauce, vinegar) → pump/gravity
- Viscous sauces (ketchup, chili sauce) → piston/pump
- Chunky sauces (salsa) → piston or rotor pump
Common Filling Principles
| Filler type | Best for |
|---|---|
| Piston (positive displacement) | Viscous sauces, higher accuracy, stable dosing |
| Pump filling | Wide viscosity range, flexible, good for continuous flow |
| Gravity filling | Low-viscosity non-foamy liquids |
Hygiene and Cleaning
- Food-grade materials (SUS304/316)
- CIP-friendly piping or quick disassembly
- Nozzle design for anti-drip and easy cleaning
Quick Checklist
- Sauce type + particle size
- Fill volume range + tolerance
- Container type (bottle/jar/pouch)
- Target output
- Temperature + voltage/frequency
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
Is piston filling better for ketchup?
Often yes. Piston fillers provide stable, accurate dosing for viscous sauces like ketchup and mayonnaise.
Can you fill sauces with chunks?
Yes, within particle size limits. Share particle size, viscosity, and container spec for confirmation.
How do you prevent dripping?
Use the correct nozzle and cutoff control, matched to viscosity and fill speed.
Do you support CIP?
We can design for CIP-friendly cleaning or fast disassembly depending on your hygiene standard.
