Oil clings. A valve that cuts off cleanly on water leaves a thread of oil on the bottle shoulder, and that thread becomes a rejected bottle and a dirty conveyor. The cut-off profile, the nozzle tip and the suck-back setting are the three things to watch at acceptance, not the fill speed.
By selecting load cell combiblocs specifically tailored for high-viscosity applications, bottling plants can minimize spillage, prevent clogging, and maintain precise filling levels for edible oil.
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.
High-viscosity substances such as edible oil present unique challenges in the filling process.
| 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 unit behind this configuration is the Edible Oil Load Cell.
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.
Site requirements, air and water consumption sit with the Filling Machine for Viscous Product.
With a warm flush and a full drain, because oil does not rinse like water. The circuit needs a low point for drainage and a filter on the return. A change between two oils is quicker than a change from oil to a water-based product.
By focusing on precision calibration, automation integration, and specialized design for high-viscosity substances, managers and decision-makers can elevate their production processes and meet the demands of the evolving bottled water industry.
The same question is worked through from another angle in The Ultimate Guide to Edible Oil Filling Machines: Accuracy.
Plus or minus 0.5 g per bottle on the reference specification. Real drift depends on product temperature, valve cut-off and the scale calibration interval, so the acceptance test should record all three.
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.
Yes, with different infeed parts and a different capping head. Glass brings breakage risk and a lower practical rate, so the two formats are usually run in separate campaigns.
