What equipment route is usually considered?
Mustard is often suited to positive-displacement or piston filling because it can be thick and sticky. Wholegrain recipes require larger passages and gentle handling, while nozzle shut-off and pack positioning must keep jar rims or bottle necks clean for closing.
Use the wholegrain recipe as a critical passage test
Average grain size is not enough. Measure the largest swollen seeds and any other inclusions under normal processing conditions, then compare them with the smallest valve, bend, hose fitting and nozzle in the proposed system.
Smooth and wholegrain mustard may also differ in density, shear response and cleaning behaviour. Include both in a changeover trial if the same equipment will handle them.
Grain passage
Confirm the largest seeds can pass without blockage, damage or ingredient separation.
Sticky shut-off
Observe nozzle tails and residue after continuous running and planned stops.
Product supply
Maintain a consistent level and distribution without excessive agitation.
Changeover
Record retained product, strip-down and cleaning between recipe families.
Match filling access and closure type to the retail format
Mustard can be packed into glass jars, plastic squeeze bottles, tubes, pouches or sachets. Narrow openings increase the importance of nozzle alignment and grain passage, while jars require controlled rim cleanliness and lid application.
| Stage or factor | What to define |
|---|---|
| Glass jar | Wide filling access, controlled headspace and compatible twist-off or screw lid. |
| Squeeze bottle | Stable empty-pack handling, narrow-neck nozzle entry and cap application. |
| Tube | Requires dedicated filling and sealing suited to the tube material and closure construction. |
| Pre-made pouch | Needs mouth opening, support and product-free seal areas. |
| Sachet | Small-dose accuracy and consistent sealing with a sticky product. |
| Foodservice pack | Larger dose, handle and cap considerations with robust case packing. |
Prove filling, cut-off and closing with commercial packaging
The chosen machine should be tested with production mustard and intended jars or bottles. Visual cleanliness is particularly important because yellow residue on a cap thread or label panel is highly visible.
Prepare representative batches
Include smooth, seeded and thickest normal recipes.
Set product feed
Use hopper, vessel or transfer arrangements that preserve uniformity.
Prove passages
Run enough wholegrain product to reveal intermittent restrictions.
Tune the nozzle
Control neck entry, deposit speed and shut-off.
Apply the closure
Keep threads, rims and sealing surfaces free from product.
Inspect the finished pack
Check exterior cleanliness, fill level, cap and label presentation.
Choose automation around pack repetition and recipe variety
A speciality producer with many flavours may value a fast-cleaning semi-automatic system. An automatic line can suit repeated bottles or jars where capping and labelling become significant labour tasks.
Single-head semi-automatic filler
Flexible recipe handling, direct operator inspection and manageable cleaning.
Compact filling and capping line
Repeatable bottle or jar handling with reduced manual closure work.
Multi-head automatic line
Higher sustained output with automatic supply, inspection and end-of-line handling.
Include intermittent blockages and restart behaviour in acceptance
A short demonstration may not reveal grain accumulation or sticky residue. Run enough packs to assess consistency after product refills, pauses and normal operator interventions.
- Smoothest and thickest recipes
- Maximum wholegrain or seed loading
- Minimum and maximum fill volumes
- Smallest bottle neck or jar opening
- Dose and ingredient distribution
- Nozzle shut-off after a stop
- Closure surfaces and exterior cleanliness
- Cleaning and recipe-change time
Common questions
Piston and other positive-displacement fillers are commonly considered for viscous mustard. Wholegrain products require valves, hoses and nozzles sized for the largest normal seeds.
Yes, where the complete product path passes the grains reliably and maintains distribution. A sustained trial should look for intermittent restriction as well as dose consistency.
Use a positive cut-off or suitable suck-back arrangement, stable product feed, accurate pack positioning and a fill profile tuned to the recipe.
Potentially, with appropriate guides, nozzles, capping equipment and change parts. The realistic changeover and every pack opening should be reviewed.
