Pulp needs either a larger valve bore or a piston filler, and it needs continuous gentle agitation in the bowl. Dead corners in the product path settle fibre, then release it as a slug into the next bottle. Bowl geometry and return-flow design matter more than valve count here.
Understanding the nuances and importance of extraction, filtration, mixing, pulp removal, and viscosity control is paramount in ensuring the production of high-quality juice products.
Compare them on the product, not on the machine. Hot fill suits acidic juice and tea in heat-resistant PET. Cold fill needs a preservative system or a separate sanitising step, but it protects heat-sensitive flavours and vitamins and uses a lighter bottle. The decision is a product decision with a packaging cost attached.
| Route | Temperature | What it costs |
|---|---|---|
| Hot fill | Up to 85 C | Heat-resistant bottle and a cooling tunnel |
| Cold fill with preservative | Ambient | Formulation constraint, not a machine constraint |
| Cold fill with in-line pasteuriser | Product-side only | Separate pasteuriser and a closed filling zone |
| Hot fill in glass | Up to 85 C | Glass mass, slower line, higher transport cost |
Throughput and change-part lists are on the Juice By Volumetric Filler page rather than in this note.
Cold filling protects heat-sensitive flavour and colour and allows a lighter bottle. It needs either a preservative system or a validated cold chain, and it moves the microbial control to the product and the plant rather than to the filler. The decision is commercial before it is technical.
The specification sheet for the Hotfill Type Filling Machine for Juice carries the utility figures quoted here.
Tea usually needs finer filtration, deaeration to protect aroma, and a fill temperature that does not strip the volatile notes. Tea also clouds after cooling, so the clarification step is part of the product design, not a filling detail.
By prioritizing extraction, filtration, mixing, pulp removal, and viscosity control, bottled water plant managers can enhance operational efficiency, product consistency, and overall customer satisfaction.
The same question is worked through from another angle in How Piston Fillers Handle Thick Juices Accurately.
Glass brings mass, breakage and a slower line. It also brings a closure decision: crown, lug or screw. A glass hot-fill line usually runs at a lower rate than the same filler on PET, and the difference is handling and inspection, not the valve.
Up to 85 C, set per product and per bottle. The exact set point and tolerance belong in the product specification, because acidity, pulp content and bottle wall thickness all move it.
No. Standard PET softens and deforms at fill temperature. The bottle needs a heat-resistant geometry, and the mould and preform are part of the project, not an afterthought.
It replaces the bottle steriliser for acidic products, because the fill temperature and hold time do the microbial work. It does not replace correct product formulation or a validated hold tube.
It depends on the hold tube volume and the heater capacity. The line is not production-ready until the return temperature is stable, so start-up time belongs in the daily plan rather than being discovered at shift start.
A controlled ramp rather than a cold plunge, so the bottle does not deform under vacuum. The tunnel zones are set per bottle geometry and validated with a temperature probe in the product.
