How do I fill gravy without blocking the nozzle or separating the product?
Control particle blockage, separation, smearing and seal contamination by stabilising gravy, its supply and the pack path before reducing speed. Use a large-bore piston or pump route with valves and nozzles sized for the limiting particulate, then prove nozzle or discharge geometry, cutoff, fill motion and restart with real production material.
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.
- Confirm the production condition of gravy: may be hot, viscous and contain particles.
- Measure the limiting pack details for jars, pouches or catering packs, including opening, stability and fill range.
- Check that product reaches the machine through a heated or insulated large-bore feed route.
- Observe exactly when particle blockage, separation, smearing and seal contamination begins.
- Compare the first, middle and final part of a batch.
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.
- The selected method does not accommodate that gravy is may be hot, viscous and contain particles.
- Product condition changes between the sample, start-up and a sustained run.
- Pack tolerance or presentation is influencing the measured result.
- The process is amplifying particle blockage, separation, smearing and seal contamination.
- The outlet or pack geometry is unsuitable.
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.
- Trial gravy using representative production batches and the full pack matrix.
- Use a large-bore piston or pump route with valves and nozzles sized for the limiting particulate.
- Plan changeover around this requirement: follow the approved hot-food and allergen cleaning method.
- Change one controlled variable at a time and record the result.
- Confirm the correction during a sustained run.
What should I send Lancing?
The most reliable recommendation is based on representative production materials and a measurable acceptance result.
- Representative sample of Gravy
- All relevant jars, pouches or catering 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

What should I check first for gravy?+
Confirm the production condition of gravy: may be hot, viscous and contain particles.
Why does this problem happen with gravy?+
The selected method does not accommodate that gravy is may be hot, viscous and contain particles.
How can I improve or correct the problem with gravy?+
Trial gravy using representative production batches and the full pack matrix.
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 Gravy; All relevant jars, pouches or catering 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.
