Linear vs multihead vs auger fillers: which route fits your product?
A practical comparison for buyers deciding between linear weighing, multihead combination weighing, auger dosing and VFFS weigh filling lines.
Practical rule: use linear weighing for simple free-flowing products, multihead weighing for speed or irregular products, and auger filling for powders that need controlled screw dosing. Use VFFS when bag forming and sealing are part of the same project.
| Route | Strength | Watch-outs | Common products |
|---|---|---|---|
| Linear weigh filler | Compact, straightforward, flexible, cost-effective starting point. | May be slower for high-output or irregular products. | Seeds, rice, granules, tea, small parts. |
| Multihead weigher | Fast combination weighing with strong output potential. | Needs careful product handling, line height and integration planning. | Snacks, pet food, sweets, frozen products, mixed products. |
| Auger filler | Controlled dosing for powders and less free-flowing products. | Bulk density, dust and clean-down requirements must be reviewed. | Spices, powders, dry blends, additives. |
| VFFS line | Integrated bag forming, filling and sealing. | Film, seal quality, coding and checkweighing affect the full line. | Coffee, powders, granules, snacks, pet food. |

FAQ
Linear vs multihead vs auger.
Comparison questions for early machine selection.
Is a multihead weigher always more accurate than a linear weigher?
Not always. Accuracy depends on the product, target weight, controls, speed and setup. Multihead weighing is often chosen for speed and combination performance.
Is auger filling only for powders?
Auger filling is mainly associated with powders and dry blends, but the final choice depends on product behaviour and pack requirements.
Can these routes be combined?
Yes. A packaging line may combine product feeding, weighing, auger dosing, VFFS, conveyors, sealing, coding and checkweighing depending on the project.
Send the product, target weight, pack format and output target.
That gives Lancing enough information to compare a linear weigher, multihead weigher, auger filler or integrated bagging line.
Like-for-like comparison
Compare each route against the same product, pack and acceptance method.
Technology comparisons become unreliable when one option is quoted at an ideal small dose and another at the real production target. Keep the test basis identical.
| Criterion | Linear / vibratory | Multihead combination | Auger |
|---|---|---|---|
| Typical starting behaviour | Free-flowing granules, beans, seeds, pellets and pieces. | Irregular pieces or higher-output combination weighing. | Fine, cohesive or less freely flowing powders. |
| How dose is controlled | Bulk and fine vibration into a load-cell weighing path. | Several partial weights combined to approach target. | Controlled screw movement; weight may be measured or verified separately. |
| Main risk | Carry-over, bridging, static and hopper-level effects. | Uneven distribution, product damage, sticking and drop timing. | Bulk-density change, tooling, agitation, dust and retention. |
| Pack interface | Manual packs, bag clamps, rigid containers or automatic machines. | VFFS, premade pouches, trays or indexed containers. | Jars, tubs, bottles, pouches or VFFS. |
| Evidence to compare | Consecutive net weights, mean, standard deviation, min/max, under-target count, finished-pack output, product quality, cleaning and changeover. | ||

Decision rule.
Choose the route that meets the agreed distribution, product-quality, cleaning and finished-pack output requirements with the fewest unsupported assumptions. Do not choose solely from the smallest published tolerance or fastest headline cycle.
