Hot filling does two jobs at once: it pasteurises the product on the way to the filler, and the residual heat sanitises the bottle and cap. That is why a hot-fill line can run an acidic juice without a separate bottle steriliser. The price is a heat-resistant bottle and a longer cooling tunnel.
The pasteurization temperature should be maintained within a specific range, typically between 160°F to 185°F, to achieve the desired microbial reduction while preserving the sensory attributes of the juice.
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.
| 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 |
For the same duty in another bottle format, the Hotfill Type Filling Machine for Juice is specified separately.
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.
By considering temperature, size, and throughput factors, bottled water plant managers and decision-makers can select a pasteurizing tunnel that meets their specific processing requirements and operational needs.
The Juice By Volumetric Filler is the matching unit when this becomes a line project.
The bottle leaves the filler at up to 85 C and has to come down in a controlled ramp. A plunge cools the outside first, the inside contracts later, and the panel pulls in. The tunnel zones are set per bottle geometry and checked with a probe in the product.
When selecting a pasteurizing tunnel for juice, it is imperative to ensure precise temperature regulation throughout the system.
The same question is worked through from another angle in How to Optimize Juice Filling Line Layout.
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.
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.
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.
With a filter change and a different valve bore for the pulp, yes. Clear juice needs finer filtration, and pulp needs agitation in the bowl so the fibre does not settle.
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.
