| Filling method | 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 |
| Package | 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.
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 |
For the same duty in another bottle format, the Filling Machine for Viscous Product is specified separately.
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.
Where this becomes a line rather than a single machine, the Filling Machine for Viscous Product is the starting point.
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 Honey & Syrup-Based Beverage Filling: A B2B Buyer's Guide.
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.
Longer than on a water line, because the dose, the stroke and often the nozzle set change. Cleaning between incompatible products usually takes longer than the mechanical change.
