Customer equipment selection guide
Filling shear-sensitive products
Gentle pumping and transfer for emulsions, aerated products and delicate structures.
Where this equipment or process fits
Gentle pumping and transfer for emulsions, aerated products and delicate structures. The product name alone is not enough to select machinery: viscosity, particles, foam, temperature, aeration, chemical compatibility and pack tolerance can change the correct solution.
Issues to challenge in a trial
- acceptable product change
- pump speed
- unnecessary recirculation
- restrictive valves
Configurations to compare
| Configuration | Selection note |
|---|---|
| lobe pump | Confirm the final specification using the real product, pack, output and cleaning method. |
| progressive-cavity pump | Confirm the final specification using the real product, pack, output and cleaning method. |
| gravity transfer | Confirm the final specification using the real product, pack, output and cleaning method. |
| large-bore gentle valve | Confirm the final specification using the real product, pack, output and cleaning method. |
Build the specification around sustained production
Record the complete dose range, product condition at the point of filling, container and closure drawings, real samples, intended labels, target output and every planned recipe or pack change. State whether output is a maximum instantaneous speed or a sustained sellable rate after refilling, minor stops, rejects and operator intervention.
Review the full process rather than the filler in isolation. Container preparation, feeding, dosing, filling, capping or sealing, labelling, coding, inspection, reject handling, conveying, accumulation and secondary packaging can each become the bottleneck. The layout also needs guards, maintenance access, cleaning access, utilities, raw-material movement and finished-goods movement.
Use representative samples and measurable acceptance criteria
A useful machinery trial challenges the difficult edges of the requirement: minimum and maximum dose, warmest and coldest product, largest expected particles, highest foam risk and packs from more than one supplier batch. Record settings, output, accuracy or presentation results, cleaning observations and open points. Those results should feed into a written factory acceptance test.
Common questions
What applications should be considered for filling shear-sensitive products?
The strongest starting applications include emulsions, aerated foods, delicate suspensions and shear-sensitive cosmetics. The final choice still depends on a representative product and pack trial.
What information is needed to specify filling shear-sensitive products?
Provide product behaviour at the real filling temperature, minimum and maximum dose, target sustained output, container and closure samples, cleaning method, utilities and available space.
What should be tested before equipment is ordered?
Test acceptable product change, pump speed, unnecessary recirculation and restrictive valves, together with achievable output, repeatability, changeover and cleaning.
Should the complete packaging line be reviewed?
Yes. Container preparation, filling, closing, labelling, coding, inspection, reject handling and accumulation need to work as one balanced process.
Can the equipment be expanded later?
Often it can, but future container formats, nozzle pitch, conveyor height, controls, guarding and upstream or downstream automation should be considered during the first specification.
