Capture cleaning/changeover search intent.
The right paste filling machine depends on how the product moves, how accurately it must dose and whether the production route is manual, semi-automatic or fully automatic. The useful starting point is the product sample, target fill volume, container and required output.
This page is for producers and contract packers comparing paste filler cleaning changeover options. The correct route depends on product movement, product recovery, fill accuracy, cleaning access and how the container is presented to the nozzle.
A filler should be specified around viscosity, dose size, container choice, cleaning needs and output target. These points often decide whether a compact semi-automatic filler, piston machine, pump-fed filler or automatic line is the better option.
Container dimensions, neck or opening size, fill height and closure style affect the filling head, conveyor layout, capping route and operator access.
A useful enquiry includes product type, fill volume, container dimensions, closure, photos of the pack and the output you want to achieve. This helps avoid under-specifying the filler or adding unnecessary automation.
The aim is to match the filling method to the production problem instead of forcing the product through the wrong type of liquid filler.
Small changes in product behaviour or pack style can change the correct filler, nozzle or line layout.
Thicker products often need positive displacement rather than gravity filling.
Sticky or stringing products may need a nozzle that closes cleanly.
Food and cosmetic projects need practical access for cleaning and changeover.
The required containers per minute decides whether semi-auto or automatic is realistic.
It can be suitable when the product path, hopper, valve and nozzle are matched to the product. For food, cosmetic and industrial paste products, the important checks are viscosity, fill volume, temperature, pack opening and whether the product strings, drips, separates or contains particles.
Send the product name, fill volume, container size, closure type, temperature, target output and whether the line needs capping, labelling or coding. Photos or short videos of the product and container are useful.
Yes. The filler can be planned as a stand-alone machine or integrated with conveyors, capping, labelling, coding and accumulation depending on the production route.
These pages help narrow the machine route before you send project details.

Cleaning performance depends on the hopper, valves, cylinder or pump, hoses, seals and nozzle. A useful demonstration starts with the last good container from one product and ends with the first accepted container from the next product.
Define how saleable product is removed before cleaning. Measure what remains in the hopper, cylinder or pump, hoses and nozzle. Product recovery may be a major operating cost for high-value creams, honey or adhesives.
List every part removed, the tools required, lifting or handling needs and the inspection points. Tool-less claims should be demonstrated on the final configured machine, including guards and surrounding line equipment.
Use the buyer’s approved water, detergent, solvent or other process. Define contact time, temperature and rinse requirements where relevant. The buyer should state how clean is verified rather than relying only on visual inspection.
Record seals, orientation, torque or clamps, recipe settings and priming product. The changeover is complete only when the next product is filling within the agreed quantity and presentation limits.
| Stage | Measure | Common boundary |
|---|---|---|
| Last good pack | Time, product condition and accepted dose. | Defines when the changeover clock starts. |
| Product recovery | Recoverable product and residual waste. | Separates saleable recovery from cleaning loss. |
| Disassembly | Parts, tools, handling and access time. | Shows whether routine changeover is practical for operators. |
| Clean verification | Buyer-approved inspection or test. | Confirms readiness rather than assuming it. |
| First good pack | Accepted dose, appearance and product identity. | Defines when the changeover clock ends. |
Not every format change needs a full wet clean, and not every product change can use the same procedure. Create a change matrix so operators know which parts, settings and verification steps apply.
Wetted parts, cleaning method, allergen or compatibility control and restart sample.
Cylinder or recipe, calibration check and sample plan.
Nozzle height, guides, sensors, cap parts and label settings.
It is product remaining in the machine path after normal drain-down. It can affect waste, cleaning time, cross-contamination and restart quantity.
No. Access, surface finish, seals, dead legs, hose layout, removable parts and the approved cleaning method all matter.
A clear method starts at the last accepted pack of the old setup and stops at the first accepted pack of the new setup, including cleaning and verification.
Yes when the product is sticky, coloured, allergenic, reactive, high-value or otherwise difficult. A water-only demonstration may not represent production.
That depends on compatibility and cross-contamination risk. Hoses, seals, nozzles or complete contact sets may be dedicated where cleaning cannot be reliably verified.
Prime the path, remove air, confirm the correct recipe and inspect sequential fills until dose and presentation meet the agreed acceptance criteria.
The complete product path can include hopper, transfer hose, cylinder, piston seal, valve seats, gaskets, connectors and nozzle internals. Suitability depends on the product, normal and cleaning temperatures, exposure time and the cleaning chemistry used between batches.
Create a parts list with material, seal or elastomer grade, surface condition where relevant, supplier evidence and replacement reference.
A component that tolerates the product may not tolerate the selected detergent, sanitiser, solvent or cleaning temperature.
Look for swelling, softening, cracking, loss of finish, residue traps, odour retention and changes that affect dosing or reassembly.
Use the full paste filler wetted-parts and seal compatibility guide when preparing the product-path schedule.
The Food Standards Agency’s review of allergen-cleaning guidance identifies equipment design, surface accessibility, residue accumulation, disassembly and monitoring as relevant factors. For a paste filler, the site should map the complete product path, define the cleaning procedure, identify inspection or test points and specify what happens when the result is not acceptable.
Include pump cavities, piston seals, valve pockets, hose bends, manifolds and nozzle shut-off parts.
State visual inspection, swabbing or other site-approved evidence and the corrective action on failure.
Include controlled parts, seal condition, line clearance and first-off production approval.
See the FSA review of food allergen cleaning guidance. Application-specific food-safety decisions remain the responsibility of the food business and its competent advisers.
