Juice Production Line
A juice production line is specified by one question first: what shelf life does the product need? Hot fill, aseptic and cold-fill lines share most equipment but differ at the filler, the bottle sterilization step and the cap application.
Line configuration
A complete juice line runs six stages: bottle washing or blow-feeding, extraction or blending and de-aeration, filling, capping, labeling and coding, then packing. Stages share one conveyor system and PLC so that output changes do not unbalance the line.
Choosing the fill method by shelf life
| Method | Typical product | Shelf life | Key equipment |
|---|---|---|---|
| Cold fill + preservative | Fresh-style juices sold chilled | 2–4 weeks | Standard rinse-fill-cap monobloc |
| Hot fill | High-acid juices in PET/glass | 6–9 months | Hot-fill filler, bottle warmer, blow-molded heat-set PET |
| Aseptic | Low-acid and premium NFC juices | 9–12 months, no preservatives | Sterile zone, H₂O₂ bottle sterilization, sterile air overpressure |
Pulp and particulate handling
Juices with pulp, juice sacs or fruit pieces need wide-bore filling valves and product tanks with agitators to keep solids suspended. Valve choice changes with pulp content — a filling valve sized for clear juice will clog or shear sacs. If your product contains particulates, tell the supplier the particle size and percentage before the line is quoted.
Capacity selection
Line capacity follows your distribution model. Regional brands starting with chilled product often begin at 1,500–3,000 BPH and upgrade later; hot-fill and aseptic lines are usually sized 4,000–12,000 BPH because the sterilization investment only pays at volume.
CIP and hygiene
Product-contact circuits need CIP (clean-in-place) with acid and caustic cycles. Aseptic lines add SIP (steam-in-place) validation. Plan the CIP skid, chemical storage and effluent routing at layout stage — retrofitting them is the most common layout mistake in juice plants.
Frequently Asked Questions
What is the difference between hot fill and aseptic filling?
Hot fill fills the product at high temperature and inverts or sprays the bottle to sterilize the cap and neck; it suits high-acid juices in heat-set PET. Aseptic filling sterilizes product, bottle and cap separately in a sterile zone and fills at ambient temperature; it suits low-acid juices and products where heat treatment would damage flavor.
Can one line handle juice with pulp or fruit sacs?
Yes, with the right valve and tank configuration. Wide-bore valves, agitated product tanks and adjusted filling temperature handle pulp; declare particle size and solids percentage during specification so the filler valves are sized correctly.
What output should I size a juice line for?
Size from daily volume and shift pattern, not peak day. Regional chilled brands often start at 1,500–3,000 BPH; hot-fill and aseptic lines are typically sized 4,000–12,000 BPH to justify the sterilization equipment.
Does the line need CIP?
Product-contact circuits need clean-in-place with acid and caustic cycles, and aseptic lines add steam-in-place validation. Include the CIP skid and chemical storage in the plant layout from the start.
