What should a factory acceptance test for a jam filling machine include?
The FAT should prove the agreed jam and pack matrix, accepted output, fill tolerance, interventions, faults, cleaning/changeover and evidence. Test is hot, sticky, viscous and can contain fruit pieces 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.
- Record ten consecutive fills by weight and note the product temperature, density or batch condition.
- Confirm the product supply remains stable at minimum and maximum hopper or tank levels.
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.
- The dosing principle is unsuitable for viscosity, particles, aeration or accuracy.
- Product conditions are changing during the run.
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.
- Stabilise product temperature, mixing and supply before retuning.
- Test a representative product and pack matrix across the full fill range.
What should I send Lancing?
The most reliable recommendation is based on representative production materials and a measurable acceptance result.
- Representative sample of Jam
- All relevant glass jars or portion packs
- Target fill and tolerance
- Required accepted output
- Photographs or video of the current process
- Product name and a sample or SDS where relevant
- Viscosity, temperature, particles, foaming and density

More quick answers about this problem
What should I check first for jam?+
Approve the format and product matrix before the FAT.
Why does this problem happen with jam?+
Acceptance language is subjective or incomplete.
How can I improve or correct the problem with jam?+
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 filling & dosing. 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 Jam; All relevant glass jars or portion packs; Target fill and tolerance; Required accepted output. Representative production samples and a measurable acceptance target are normally more useful than a catalogue description alone.
