| Valve type | Piston dosing, or load cell for high-value product |
| Viscosity | Up to 10,000 cP with the right bore |
| Products | Sauces, pastes, pulp juice, honey, detergents |
| Bottle or can | PET, glass, jar, pouch by configuration |
| Key control | Dose repeatability, drip-free cut-off, product temperature |
| Cleaning | CIP circuit with a bypass for high-solid product |
A piston draws a fixed volume into a cylinder and pushes it out, so the dose does not depend on how fast the product flows. A gravity or pressure valve depends on flow time, and thick product makes that time unpredictable. For anything above a few thousand cP, the piston is the simpler answer.
These features enable fine-tuning of fill volumes based on factors like product viscosity, container size, and line speed, ensuring reliable performance and minimizing product giveaway.
Four things: the piston seal, the product temperature, the supply pressure at the inlet, and the presence of solids at the valve seat. A worn seal leaks past the piston and the dose falls slowly, which is why the drift is invisible from one bottle to the next and obvious over a shift.
| Product type | Dosing | Main risk |
|---|---|---|
| Smooth sauce | Piston | Drip at the nozzle |
| Chunky sauce | Piston with large bore | Bridging at the valve seat |
| Honey and syrup | Piston or load cell | Stringing and slow cut-off |
| Pulp juice | Piston | Fibre settling in the bowl |
Site requirements, air and water consumption sit with the Edible Oil Load Cell.
A suck-back stroke at the end of the dose pulls the tail back into the nozzle. The stroke length, the nozzle bore and the product viscosity have to be matched, and they change when the recipe changes. Drip is a setting problem before it is a nozzle design problem.
The specification sheet for the Filling Machine for Viscous Product carries the utility figures quoted here.
High-solid product does not flush like water. The CIP circuit needs a pre-rinse at temperature, a bypass around the filler bowl, and a return path that does not leave product in a dead leg. Cleaning time on a sauce line is often longer than the production changeover, and both belong in the capacity plan.
The same question is worked through from another angle in How Piston Fillers Handle Viscous Products.
Seal wear and product temperature. A worn seal leaks past the piston and the dose falls gradually; a colder product fills the cylinder less completely. Both show as a slow downward trend, which is why the sample is weighed, not judged by eye.
Yes, if the bore and the valve seat are sized for the largest particle. A filler set for smooth sauce will bridge on pulp, so the particle size is a specification input, not a detail.
Most often a worn piston seal or a falling product temperature. Both reduce the actual volume delivered per stroke. Check the seal and log the product temperature before adjusting the stroke.
It needs a cleaning circuit designed for the product. High-solid product needs a pre-rinse and a bypass; a low-solid sauce may clean in place with the same circuit as a juice line.
Piston doses by displacement and is faster; load cell doses by weight and is more accurate when density varies. For a chunky product with variable density, weight filling avoids give-away.
Yes, with a jar infeed, a different gripper and a different capping head. The filler itself is the same; the handling around it is not.
