Product Compatibility
Fillers are not universal. Water-like liquids, oils, creams, chunky sauces, powders, granules, and pastes require different filling principles. Always tell suppliers the viscosity, temperature, particle size, foaming behavior, and whether the product changes thickness during the day.
Checklist
| Check | What to document | Why it matters |
|---|---|---|
| Fill volume | Minimum, maximum, and common fill size | Determines pump type and cylinder range. |
| Accuracy | Target tolerance by weight or volume | Affects rejects, label claims, and cost control. |
| Container | Opening size, height, shape, cap, and material | Drip control and nozzle positioning depend on geometry. |
| Cleaning | Batch changes, allergens, sanitation, disassembly time | Cleaning can dominate labor cost. |
| Utilities | Power, compressed air, bench space, operator count | Missing utilities delay installation. |
Sample Testing
If the machine will handle a sticky, foaming, chunky, or food-contact product, sample testing is not optional. Send product and container samples or request a live video using a close substitute. Ask the supplier to show fill accuracy, drip behavior, cleaning steps, and speed after operator loading is included.
Before Paying a Deposit
- Confirm every product-contact material and seal material.
- Confirm spare seals, nozzles, tubing, and valves with part numbers.
- Request the real tested output per hour, including manual loading and wiping.
- Confirm whether compressor, hoses, foot pedal, and change parts are included.
