Machine route
Linear weigh fillers
For free-flowing granules, beans, seeds, snacks and small components.

Weigh filling machine range for dry products and packaging lines.
Compare the main machine routes before shortlisting a weigh filler for powders, granules, coffee, snacks, pet food, chemicals or hardware.
Machine range
Choose the weighing or dosing route before the model.
The right weigh filler depends on product flow, target weight, tolerance, speed, pack format and how the machine connects into the rest of the packaging line.
Machine route
Multihead combination weighers
For higher-throughput portioning where speed, accuracy and pack presentation matter.

Machine route
Auger fillers
For powders, dry blends and products that need controlled screw dosing.

Machine route
VFFS weigh filling lines
For roll-film bagging lines that form, fill and seal in one connected process.
View route →| Machine route | Best starting point | Typical products | Key questions |
|---|---|---|---|
| Linear weigh filler | Compact weight filling for free-flowing products. | Beans, seeds, granules, rice, tea, small parts. | Target weight, feed consistency, outlet height, operator loading. |
| Multihead combination weigher | Higher-speed weighing with combination selection. | Snacks, pet food, confectionery, frozen or irregular products. | Head count, product fragility, buckets, discharge and downstream machine. |
| Auger filler | Controlled screw dosing for powders and blends. | Spices, powders, additives, cleaning powders, dry mixes. | Dust, density, hopper agitation, fill weight and cut-off. |
| VFFS weigh filling line | Roll-film bagging with weighing, filling and sealing in one line. | Coffee, grains, powders, granules, snacks and pet food. | Bag size, film, coding, sealing, checkweighing and line footprint. |
Why compare machine routes first.
Different products need different dosing principles, feed systems and discharge layouts. Comparing the main routes first helps you avoid choosing a machine before the product, pack and output target have been checked.

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.
Selection matrix
Choose the measuring principle and pack interface together.
A machine route should be compared on the same product, target weight and finished-pack basis. Head count, hopper size or a headline speed is not enough on its own.
| Route | Strong starting point | Main limitations to test | Pack and line interface | Evidence required before acceptance |
|---|---|---|---|---|
| Linear or vibratory weigher | Free-flowing granules, beans, seeds, pellets and many small components. | Bridging, static, fines, inconsistent bulk density, feeder carry-over and slow trim feed. | Operator-presented bags or containers, bag clamps, conveyors, premade pouch machines or VFFS discharge. | Consecutive fill distribution, hopper-level effect, output with real pack handling and clean-down observation. |
| Multihead combination weigher | Irregular pieces and higher-output projects where several weigh heads can combine portions to reach target. | Fragility, sticking, product distribution across heads, drop height, bucket volume and product-in-seal risk. | VFFS baggers, premade pouch systems, trays, jars or other receiving equipment with timed discharge. | Head utilisation, mean and standard deviation, piece damage, rejects, line timing and output at the agreed target. |
| Semi-automatic weigh/depositor | Shorter runs, varied products or packs, and projects where an operator presents each pack. | Operator cycle, bag support, ergonomics, refill frequency and consistency of pack positioning. | Bench, stand or conveyor-fed arrangement with manual or assisted pack presentation. | Real operator trial, sustained output rather than a short burst, changeover time and net-weight distribution. |
| Auger with weight verification | Fine or less free-flowing powders where screw dosing is more controllable than open vibration. | Bulk-density change, screw/tooling choice, agitation, dust, product retention and cross-contamination. | Jars, tubs, bottles, pouches or VFFS. Detailed auger selection belongs on the specialist Lancing powder sites. | Product trial across the smallest and largest dose, cleaning review and separate verification of weight control. |
| VFFS weigh filling line | Automatic bags formed from roll film with the weigher synchronised to forming, filling and sealing. | Film, former, bag length, product drop, seal contamination, coding, jaw timing and finished-pack discharge. | Ready/busy and discharge signals between weigher and bagger, plus checkweigher or reject control downstream. | Full-line run with production film, representative product, finished bags and an agreed acceptance protocol. |
Verified model references
Use figures only with their test conditions.
The LU-999 reference specification covers 10–999 g with a vibratory weighing route, an approximately 280 × 280 × 270 mm hopper, a stated 6–15 bags/minute and approximately ±2 g, all dependent on material, target weight and pack handling.
The LU-GFKL420 reference is a ten-head VFFS configuration covering 10–2500 g, quoted for 500 g to 1 kg bags, with approximately 1.3 L per head. Its 5–60 bags/minute and approximately ≤0.3–1 g references are conditional on product, target, bag size, film, former and trials.
Data Lancing needs to compare models.
- Representative product sample and the expected normal variation between batches.
- Smallest, normal and largest target weights.
- Actual pouch, bag, jar, tub or container dimensions.
- Required output measured at the finished-pack point.
- Accuracy or legal/QA acceptance basis, including whether average quantity rules apply.
- Upstream feed, hopper refill, checkweigher, sealing, coding and conveyor scope.
