How do I change between pack sizes when filling seeds?
Create a controlled recipe and mechanical setting sheet for each approved pack. Change parts, guides, nozzle height, dose, timing and first-off checks must all be linked; for seeds, also include dry-clean between varieties and control cross-mixing.
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.
- List every mechanical and recipe setting that changes.
- Use datum scales or fixed references rather than operator judgement.
- Run first-off checks at the lowest and highest approved fill.
- 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.
- Settings are recorded without the matching physical change parts.
- Residual product changes the first fills after restart.
- The pack matrix contains an untested opening or stability limit.
- 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.
- Create format sheets with photographs and measured settings.
- Stage clean change parts before the line stops.
- Approve first-off samples before releasing normal production.
- 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 Seeds
- All relevant pouches, jars or bags
- 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

More quick answers about this problem
What should I check first for seeds?+
List every mechanical and recipe setting that changes.
Why does this problem happen with seeds?+
Settings are recorded without the matching physical change parts.
How can I improve or correct the problem with seeds?+
Create format sheets with photographs and measured settings.
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 Seeds; All relevant pouches, jars or bags; Target fill and tolerance; Required accepted output. Representative production samples and a measurable acceptance target are normally more useful than a catalogue description alone.
