| Filling method | Load cell net-weight, or piston dosing |
| Capacity | 12,000-36,000 BPH at 0.2-2 L |
| Viscosity | Up to 10,000 cP |
| Accuracy | Plus or minus 0.5 g per bottle |
| Container | PET or glass |
| Key control | Weight per bottle, temperature, drip-free cut-off |
Four inputs fix the shortlist: the product, the package, the daily demand and the number of formats per week. Everything else, including the brand of the PLC, is a detail that can be settled after those four are written down.
Oil density changes with temperature, so a fixed volume delivers a different mass in the morning and in the afternoon. A load cell weighs what goes into the bottle and stops at the target mass. That is why an oil line is specified in grams and a water line in millilitres.
| Dosing method | Accuracy basis | When it fits |
|---|---|---|
| Load cell | Net weight per bottle | Density moves with temperature |
| Piston | Displacement volume | Stable density, high speed, thick product |
| Volumetric valve | Chamber volume | Low-viscosity oil at steady temperature |
| Flow meter | Measured volume | Continuous flow, limited pulp or solids |
The Edible Oil Load Cell is the matching unit when this becomes a line project.
Above a few thousand cP the product moves by pressure and time rather than by gravity, so the bowl, the feed pipe and the valve bore all grow. Temperature control also becomes part of the filling specification, because a cold oil at 10 C and the same oil at 25 C behave like two different products.
Sizing for this duty runs through the Filling Machine for Viscous Product, where the valve count is set out.
A piston filler doses by displacement and is faster and simpler for thick products with a stable density. A load cell is better when the product density moves, when the bottle weight varies, or when the legal fill is defined by net content. For high-value oil in variable PET, weight wins.
The same question is worked through from another angle in The Ultimate Guide to Edible Oil Filling Machines: Accuracy.
Nothing, if the filler tares each bottle before dosing. That tare step is what separates net-weight filling from a flow meter. Without it, a heavy bottle delivers less product and the label claim fails.
Yes, with change parts and a recipe. Above 2 L the fill time per valve grows and the practical BPH drops, so the line is normally specified for one dominant format with a second format as a changeover.
Some packers dose nitrogen into the headspace to slow oxidation, especially for polyunsaturated oils. It is an option, and its value depends on the oil and the target shelf life, not on the filler.
Yes, with a longer fill time per valve. Above 2 L the practical rate per valve drops, so a 5 L line is normally specified for that format rather than shared with 1 L.
Product temperature, a worn valve seat, or scale calibration. Log the weight and the temperature together; a drift that follows temperature is a process problem, not a valve problem.
With a flushing cycle sized for the oil and the pipe run. High-viscosity oil needs a warm flush and a longer drain time than water, and the changeover belongs in the production plan.
