Pack presentation remains manual
The operator opens, supports and presents the pack unless automatic handling is separately included.

LU-FM710 semi-automatic auger filler with a separate weighing device for setup and dose verification.
A flexible operator-fed powder filler that combines volumetric auger dosing with a separate weighing device to support setting, checking and correction of the approved recipe.
- Filling modes
- Volumetric or weight-assisted
- Reference range
- Approximately 10 g to 2,000 g
- Hopper
- Approximately 25 litres
Direct answer
What does the LU-FM710 weighing device add to an auger filling process?
The Lancing LU-FM710 is a semi-automatic auger filler with a separate weighing device. The auger provides the controlled dose while the scale supports recipe setting, verification and correction. The operator still presents, removes and closes the pack unless additional handling equipment is specified.
Weight assistance is most useful when the process needs a clear checking step or when product bulk density may vary enough to justify regular verification. It is not the same as an inline automatic checkweigher and it is not automatically a legal-for-trade weighing system.
Good initial fit
- Operator-fed pouches, bags or compatible rigid packs
- Target fills within the approved 10–2,000 g working envelope
- Projects needing a separate weight-check step
- Growing production that does not yet justify automatic pouch handling
- Products that require trial-led recipe verification
Verified model data
LU-FM710 reference specification
The machine and weighing arrangement are configured around the approved powder, pack and target range.
| Specification | Reference model data | Application note |
|---|---|---|
| System format | Semi-automatic auger filler with separate weighing device | Operator handles the pack before and after filling |
| Filling modes | Volumetric auger dosing or weight-assisted filling | The approved operating method must be documented |
| Working envelope | Approximately 10–2,000 g | Selected tooling and product trials define the practical range |
| Hopper | Approximately 25 litres | Final agitation and refill method depend on product behaviour |
| Published cycle envelope | Approximately 1–30 fill cycles per minute | Practical finished-pack output is product and operator dependent |
| Controls | PLC / touchscreen recipe and fill-parameter control | Access and recipe verification should match the site procedure |
| Pack support | Height-adjustable support and weighing arrangement | Pack stability and opening dimensions require approval |
| Power | Approximately 1.25 kW; UK-compatible configuration | Final electrical execution is confirmed for the project |
| Approximate size / weight | Main unit 450 × 650 × 1,860 mm; scale 265 × 265 × 570 mm; approximately 128 kg total | Allow working space for the operator, samples and downstream closure |
Process choice
Volumetric-only and weight-assisted operation are different workflows.
The correct mode depends on production control requirements and how consistently the powder refills the auger flights.
| Approach | How it works | Main consideration |
|---|---|---|
| Volumetric auger dosing | The approved auger rotation and speed dispense a repeatable volume | Weight follows volume only while bulk density and product condition remain controlled |
| Weight-assisted setup | Trial fills are weighed and the recipe is adjusted to the target | The scale helps establish and verify the volumetric recipe |
| Routine verification | Selected filled packs are weighed during production | Sampling frequency and response limits must be agreed |
| Automatic feedback | A measured trend can be used to correct the dose where a suitable control interface is specified | Correction rules must not chase random variation or faulty measurements |
System boundaries
Plan the complete operator workflow.
Closing remains separate
Filled packs normally move to a capper, heat sealer or other closing stage after the weighing step.

Legal-metrology and packaged-goods controls depend on the site process, equipment status and applicable requirements.
View detailsSample-trial plan
Prove the LU-FM710 recipe with representative material and packs.
The trial should show whether weight assistance solves a stable density trend or merely exposes wider product and handling variation.
| Check | What to record |
|---|---|
| Powder condition | Batch, bulk density, aeration, moisture, hopper level and refill event |
| Installed tooling | Auger, tube, nozzle, agitation and support arrangement |
| Dose results | Individual weights, average, spread, sequence and any rejected or disturbed fills |
| Operator method | Pack opening, placement, support, removal, weighing and transfer to closure |
| Correction method | When settings may be adjusted, by whom, and the limits that trigger investigation |
| Finished pack | Headspace, rim or seal cleanliness, settling and closure quality |
Buyer questions
Common questions about the LU-FM710.
Does the LU-FM710 weigh every pack automatically?
The referenced configuration uses a separate weighing device. The exact workflow can be weight-assisted or volumetric, but automatic inline weighing of every moving pack is a different arrangement that must be specified separately.
Can weighing remove the effect of changing bulk density?
Weighing can reveal and help correct a stable shift, but it cannot make poor powder feed, bridging, aeration or inconsistent operator handling disappear. The powder and hopper process still need to be controlled.
Is the separate scale legal for trade?
The separate scale should be treated as a process aid unless its approved legal-metrology status and the complete packaged-goods process are specifically confirmed.
Can the machine fill jars and pouches?
Compatible pouches and rigid packs can be considered when the opening, stability, support, fill volume and closing process are suitable. Production-intent samples are required.
What requirements point to the larger LU-FM750F platform?
The LU-FM750F should be considered when a larger 50 litre hopper, larger published tooling windows or a modular feeder-and-sealer line are more appropriate to the target fills and production method.
Specification basis and project boundary
Specification basis: Lancing technical specification and quotation records reviewed 20 August 2026. Values shown are reference machine data, not a guarantee for every powder, dose or pack. Final construction, tooling, utilities, output and fill performance are confirmed after product, pack and application approval.
Representative samples should be used to verify bulk density, flow, dust, aeration, bridging, cut-off, pack clearance and the agreed checking method before final specification.
