| Valve type | Hot-fill, up to 85 C |
| Rated output | 6,000-36,000 BPH at 0.2-2 L |
| Container | 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.
The pasteurizing tunnel, a key component in juice processing lines, is designed to subject the product to specific temperature-time profiles necessary for pasteurization.
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.
The precise control of temperature and time is critical to ensure uniform heating throughout the product and guarantee the destruction of pathogens while minimizing undesirable changes in taste, color, and nutritional content.
| 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 matching unit when this becomes a line project.
Cap seals and filling valve O-rings, because they see the highest temperature every cycle. A seal that is fine on a water line at 20 C will harden in weeks at 85 C. The spare parts list should carry those two items in proportion to the number of valves, not as a single set.
Site requirements, air and water consumption sit with the Juice By Volumetric Filler.
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.
The same question is worked through from another angle in Juice Production Line FAQ: Raw Fruit Sealed Bottle.
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.
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.
