What should a factory acceptance test for a pet food kibble filling machine include?
The FAT should prove the agreed pet food kibble and pack matrix, accepted output, fill tolerance, interventions, faults, cleaning/changeover and evidence. Test is irregular, dusty and can break during handling under realistic supply conditions, including restart after a controlled stop.
What should I check first?
Record the machine state and the finished result before changing settings. This helps identify where control is first being lost.
- Approve the format and product matrix before the FAT.
- Define sample size, tolerance, output period and permitted interventions.
- Include low product, missing pack, stop and restart tests.
- Measure bulk density from several parts of a production batch using the same method.
- Observe product behaviour at high, medium and low hopper level.
Why is this production problem happening?
Work from the evidence and change one variable at a time. These are the most relevant causes to investigate first.
- Acceptance language is subjective or incomplete.
- Only ideal materials are available at the FAT.
- Interfaces and utilities are treated as later site issues.
- Variable bulk density or particle distribution changes the delivered quantity.
- Hopper geometry and agitation do not provide consistent presentation.
How can I correct or improve it?
Make a controlled change, repeat the same measurement and compare the result before moving to the next adjustment.
- Use a signed protocol with results and open actions.
- Record settings, samples, video and measured output.
- Carry unresolved site-interface points into a controlled SAT plan.
- Control hopper level and refill method.
- Trial auger, linear weigh, combination weigh or net-weigh methods as appropriate.
What should I send Lancing?
The most reliable recommendation is based on representative production materials and a measurable acceptance result.
- Representative sample of Pet food kibble
- All relevant bags, pouches or tubs
- Target fill and tolerance
- Required accepted output
- Photographs or video of the current process
- Representative product sample and safety information
- Bulk density range, particle size and flow observations

What should I check first for pet food kibble?+
Approve the format and product matrix before the FAT.
Why does this problem happen with pet food kibble?+
Acceptance language is subjective or incomplete.
How can I improve or correct the problem with pet food kibble?+
Use a signed protocol with results and open actions.
Which part of the production line does this question relate to?+
This question relates primarily to powder & granule handling. It may also be affected by upstream product or pack supply and by downstream handling, so check the full production sequence rather than one machine in isolation.
What should I send when asking for a machinery recommendation?+
Send Representative sample of Pet food kibble; All relevant bags, pouches or tubs; Target fill and tolerance; Required accepted output. Representative production samples and a measurable acceptance target are normally more useful than a catalogue description alone.
