Product feed
Thick products may need an elevated hopper, transfer pump, follower plate or controlled pressure to keep the dosing chamber supplied.
Bottle filling applications
Sauce, Cream & Viscous Product Filling
Viscous products need a filling route that controls feed, trapped air, particles, temperature and nozzle cut-off while remaining practical to clean between batches.
Application engineering
Build the specification around the production product
A laboratory viscosity or marketing description is not enough. The filler should be reviewed using product at the normal process temperature, representative bottles and the planned supply method.
- Viscosity at actual filling temperature
- Particle size, concentration and fragility
- Tendency to aerate, string, drip or separate
- Hopper capacity, mixing or heating requirement
- Bottle/jar opening and required nozzle clearance
- Cleaning time, strip-down and product-change procedure
Sauce, Cream & Viscous Product Filling. The recommended configuration will be matched to your product, container, fill range and required output.
Application risks
Four issues to resolve before machine selection
These factors often decide the filling principle, nozzle design, cleaning route and automation level.
Stringing and cut-off
The nozzle and valve must stop the product cleanly enough to protect the neck, seal and label area.
Particles
Herbs, seeds, fibres or pieces can restrict valves and nozzles and change dose consistency.
Temperature
Honey, waxy creams and similar products may need controlled heat or mixing where the formulation allows it.

Questions
Sauce, Cream & Viscous Product Filling FAQs
Application-specific answers for early project planning.
Can a paste filler handle sauce with pieces?
Some large-bore valves and nozzles can handle particles, but product samples are essential. Piece size, shape and concentration must remain within the agreed path.
Why does fill weight vary with a viscous product?
Air pockets, temperature, product separation, inconsistent hopper feed and stringing can all change the delivered amount or the measured weight.
Can heated hoppers be used?
They can be considered for suitable formulations, with appropriate control and guarding. Product safety and quality limits must be defined by the user.
How is the machine cleaned?
Cleaning may involve draining, flushing, product recovery and dismantling of hopper, cylinder, valves, hoses and nozzles. The required method should shape the machine design.
Turn the application into a testable machine brief.
Send product data, representative bottles, closures, fill range and output. Lancing Ltd can identify the most credible filling route.
Bottle and pack evidence
Match viscous product movement to the bottle opening and clean release
Sauces, creams and similar products can change with temperature, particles, aeration and time. The pack opening, product feed and nozzle shut-off should be tested using representative production material.
Product structure
Record viscosity, inclusions, fragility, temperature, separation and whether the product strings or settles.
Opening and fill path
Check the smallest bottle or jar opening, shoulder shape and the required nozzle insertion or cut-off arrangement.
Clean-down and changeover
Define product recovery, dismantling, wash method, allergen or colour changes and restart checks.
Three guides that improve the first review
Prepare representative samples
Include every bottle and closure that is expected to run, not only the easiest format. Note the normal product condition, fill range, batch pattern and the clean presentation required at the next process.

Positive-displacement option
Assess the complete piston path for sauces, creams and gels
For suitable pumpable products, piston filling can provide controlled displacement and a defined discharge stroke. Particle passage, cylinder range, product feed, temperature, stringing, valve access and nozzle cut-off must all be tested together.
Representative evidence
- Coldest and most viscous normal product
- Largest particle or inclusion
- Minimum and maximum dose
- Smallest bottle neck
- Cleaning and first-off sequence
Recipe-specific trials
Separate sauce quantity from the condition of its ingredients
A sauce containing herbs, seeds or pieces needs two different checks: how much product reaches the bottle, and whether the bottle contains the required recipe in the required condition. Inspect the supply vessel, transfer system and fill path as one assembly. A wide nozzle does not prove that the upstream valve or pump can handle the same product.
Include the end of the batch in the trial
Compare samples from the beginning, normal running and low supply level. Include a normal pause before collecting restarted bottles. Ask the product owner how separation, ingredient damage or a different solids proportion will be judged. Record those findings alongside quantity and neck-cleanliness results.
Keep a recipe change visible in the evidence
A smooth cream, emulsified dressing and sauce with inclusions may look similar in a quotation but place different demands on the product path. Identify the formulation used for every recorded result and agree what needs retesting for a changed recipe. Do not assume that the same nominal viscosity means the same passage or cleaning requirement.
The particles, pulp and seeds guide provides the path and sampling worksheet. For a smooth sweet product, use honey and syrup bottling. Include component documentation where the supplied contact materials form part of approval.
