| Filling system | Hot-fill, up to 85 C |
| Capacity | 6,000-36,000 BPH at 0.2-2 L |
| Package | Heat-resistant PET geometry, or glass |
| Line | Hot-fill monobloc with tunnel pasteuriser |
| Products | Juice, tea, nectar, functional drinks |
| Key control | Fill temperature, hold time, cap seal |
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.
Temperature monitoring is a critical aspect of maintaining food safety in hotfill juice lines.
Fill temperature and hold time together set the pasteurisation result. Below the target, shelf life is at risk; above it, the product cooks and the bottle deforms. The number belongs to the product and the bottle, not to the machine, and it should be written into the acceptance protocol with a tolerance.
Automated temperature monitoring systems integrated into hotfill juice lines provide real-time data on the temperature of the juice at different stages of production.
| 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 Hotfill Type Filling Machine for Juice is the reference unit for this configuration.
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.
A different bottle format means a different unit; see the Juice By Volumetric Filler.
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.
These systems help plant operators quickly identify and address any deviations from the optimal temperature range, minimizing the risk of producing unsafe products.
The same question is worked through from another angle in Benefits of Volumetric Hotfill Machines for Glass Bottles.
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 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.
