A practical production route
Use the eight stages below to compare the complete route for your product, from preparation and pack handling through to dispatch. For fruit spread, the critical issues are scalding, cooling in pipework, container distortion and loss of closure vacuum.
Define the product window
Measure the production range for fruit spread: fill volume or weight, density, viscosity or flowability, temperature, largest inclusion, foam, chemistry and shelf-life process. Select equipment against the worst case, not the easiest sample.
Prepare and feed consistently
Prepare fruit spread to a repeatable specification and supply the filler through a jacketed, agitated holding tank with insulated transfer lines. Control batch-to-batch variation and avoid long, restrictive or difficult-to-clean pipework.
Apply the required treatment
Establish the validated cook, pasteurisation or hot-fill temperature for fruit spread. Use a jacketed holding vessel and verify temperature at the filler, not only in the main tank.
Prepare the empty pack
Inspect empty heat-resistant glass jars for damage, contamination and dimensional variation. Rinse, air-clean or sterilise only where the product risk assessment and packaging specification require it.
Fill accurately and cleanly
Use a heated piston, lobe, rotor or progressive-cavity filler. Monitor temperature at the tank, transfer line and filling nozzle rather than at one point only. Set the nozzle and container handling so the outside of the heat-resistant glass jars remains clean for closing and labelling.
Close or seal the pack
Apply vacuum twist-off lids with controlled headspace and closure torque. For hot-filled packs, confirm the cooling profile produces the required vacuum and tamper-button response.
Label, code and verify
Apply wrap-around, front-and-back, top or tamper-evident labels as required by the heat-resistant glass jars. Add batch/date coding and use vision or barcode checks where label mix-up is a material risk.
Inspect and pack for distribution
Check fill quantity, pack integrity, code and presentation before accumulating or case packing. Confirm the finished heat-resistant glass jars survives handling, sleeve wrapping, case packing, palletisation and transport.
Equipment options for fruit spread
These machine types provide an initial route. Dose range, contact materials, output, utilities, change parts and controls should be agreed after a representative product and pack trial.

Product behaviour
Test viscosity, density, foaming, particle size or flowability using production-representative fruit spread. Monitor temperature at the tank, transfer line and filling nozzle rather than at one point only.
Hot-product safety
Above 45°C, assess scalding and burn exposure. Use enclosure, splash protection, guarded hot surfaces, safe drain-down and appropriate PPE.
Cleaning and changeover
Plan for safe drain-down, guarded hot surfaces and a cleaning method suited to cooked-on residues. Confirm recovery, flushing, allergen or chemical segregation and safe disposal before purchase.
Pack validation
Run the actual heat-resistant glass jars and vacuum twist-off lids through filling, closing, labelling and transit tests. Supplier drawings alone do not show real production variation.
Selecting equipment by weekly throughput
| Weekly volume | Typical equipment level | Planning approach |
|---|---|---|
| Under 500 | Desktop or manual-assist | Prioritise low changeover time, flexible tooling and safe repeatability. |
| 500–2,000 | Compact semi-automatic | Separate filler, closer and labeller can provide a practical step up without a full conveyor line. |
| 2,000–10,000 | Two-head or compact inline | Use controlled product feed, powered conveyors and automatic closing or labelling where labour is the constraint. |
| 10,000+ | Multi-head automatic line | Balance every station, include accumulation and specify inspection, rejection and end-of-line handling. |
Prove the line with your product and packaging
The most useful test uses the final fruit spread, heat-resistant glass jars, vacuum twist-off lids, label and code. Include the most difficult size or formulation, not only the easiest product.
Discuss this applicationCommon questions about filling fruit spread
What filling machine is best for fruit spread?
A heated piston, lobe, rotor or progressive-cavity filler is the usual starting point because fruit spread behaves as a product filled hot to support flow, container treatment or the validated preservation process. The actual choice depends on dose, temperature, inclusions, required accuracy, cleaning regime and output.
Can fruit spread be filled into hot-fill glass jars?
Yes, provided the heat-resistant glass jars, vacuum twist-off lids and product are compatible. Test dimensional variation, fill temperature, headspace, leakage, closure performance, label adhesion and distribution before specifying the line.
Should fruit spread be filled hot or cold?
Fruit Spread may be filled hot where the recipe and shelf-life process require it. Use a jacketed tank and insulated transfer, then prove the fill temperature, closure application and cooling profile with the actual heat-resistant glass jars.
How is fruit spread kept hot through the filler?
Use a jacketed tank, insulated or heated hose and a temperature-controlled nozzle. Monitor the coldest point and minimise stoppage time that allows product to cool in the circuit.
How should hot-fill glass jars be closed after filling fruit spread?
Apply vacuum twist-off lids with controlled headspace and closure torque. For hot-filled packs, confirm the cooling profile produces the required vacuum and tamper-button response.
What output can a fruit spread filling line achieve?
Output depends on dose size, pack handling, fill time, closure method, cleaning and operator loading. As a planning guide: desktop equipment suits under 500 packs/week, compact systems 500–2,000, two-head lines 2,000–10,000 and multi-head systems 10,000+.
What samples are needed to test fruit spread?
Supply representative fruit spread, the complete heat-resistant glass jars, vacuum twist-off lids, labels and any coding specification. Include the full product range, especially the highest viscosity, largest inclusion or most difficult pack size.
