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.
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.
Choose a filler equipped with materials and components designed to handle high temperatures effectively.
| 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 |
The unit behind this configuration is the Hotfill Type Filling Machine for Juice.
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 Juice By Volumetric Filler is the reference unit for this configuration.
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.
Temperature tolerance is another critical aspect when selecting a mechanical hotfill glass bottle filler.
The same question is worked through from another angle in How to Optimize Pasteurizing Tunnels for Juice Production.
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.
Usually fill temperature above the bottle rating, or a vacuum that forms as the product cools. Check the fill temperature against the bottle specification and the cap seal before changing the cooling profile.
Heat-sensitive pigments and vitamins degrade above the product temperature limit. The fill temperature and the hold time are the two variables; lowering either protects colour and shortens the microbial margin.
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.
