Beans, grains and nuts
Assess piece size, oil, surface condition and hopper volume. Combination weighing may improve target selection where portions remain stable.
Coffee, tea and dry-food applications should be separated by product form. Beans, leaves, grains and nuts may be free flowing; ground coffee and fine mixes can require a different dosing method. The pack format and product-quality requirements are equally important.
Whole coffee beans, many grains and some loose teas can form stable portions for weighing. Ground coffee, powdered ingredients or fine drink mixes can aerate, compact or change bulk density and may be better suited to an auger filling route. A product trial should include normal variation and refill conditions.
Assess piece size, oil, surface condition and hopper volume. Combination weighing may improve target selection where portions remain stable.
Low bulk density can fill available volume quickly. Check feeder control, static, leaf damage and the full product drop.
Check aeration, dust, bulk-density change and refill behaviour before deciding whether weighing or auger dosing is appropriate.
| Application factor | Why it matters | Trial evidence |
|---|---|---|
| Product aroma and residue | Retained product and cross-flavour can affect changeover requirements | Inspection after emptying and the agreed cleaning method |
| Fragile leaves or pieces | Vibration and drop height can alter product quality | Before-and-after sample comparison |
| Pack format | Pouches, jars and bags have different opening and settling needs | Real-pack trials and finished presentation |
| Fine particles | Dust can enter seals, controls or surrounding equipment | Sustained run, housekeeping and seal inspection |
| Product changeover | Beans, blends and flavours may require controlled release | Retained product, elapsed time and first acceptable pack |
A VFFS line forms the bag from film and requires precise dose timing. A pre-made pouch line requires reliable pouch presentation and opening. The weigher discharge should be assessed with the chosen pack route.
Provide the product form, target weights, pack style, output, available height, cleaning expectations and whether the line will handle multiple blends or flavours. Include representative product and empty packs for the trial.
Record individual weights, giveaway, output, breakage, retained product, dust, seal quality and changeover observations. The test should include normal product variation and enough running time to reveal build-up or feeding changes.
Lancing can review whether combination weighing, linear weighing, auger filling or another route is the most practical starting point.
Request machine adviceNot necessarily. Beans and grounds behave differently, so combination weighing may suit beans while ground coffee can require controlled auger dosing.
Potentially, but low bulk density, leaf fragility, static and hopper volume must be checked with the real tea.
Yes. The pack opening, product settling and seal area influence the mechanical and timing requirements.
Define the cleaning method, acceptable retained product and the evidence needed before the next blend or flavour is released.
