Fruit Juice & Nectar — Line Configuration Options and Investment Levels

1. The preservation decision

Juice projects start with one decision: how the product is preserved. Hot-fill is the mainstream for nectar and pulp products — fill hot into a heat-rated bottle, cap, and let the heat held in the package complete the preservation. Cold filling exists as an alternative with its own preservation route (contact Sunswell for the cold-fill option). The preservation route sets the filler, the bottle and the whole upstream process, so it is decided first.

Within hot-fill, the configuration levels differ in output, integration and footprint — not in the preservation logic.

2. The configuration levels

Investment rises with integration; the payback shows in footprint, labour and bottle weight. The drink is the same in all three — the levels are an efficiency ladder, not a quality ladder.

3. Standalone hot-fill filler

A standalone hot-fill filler takes prepared, heated product from the batching and heat-treatment skid and fills heat-rated bottles. It handles PET and glass through different infeed handling, changes formats with change parts, and matches small-to-mid output. For a plant that bottles several products or packages, it is the flexible choice.

The standalone route also suits producers who already run batching and heat treatment and are adding filling capacity — the filler slots into an existing front end.

4. Integrated line

An integrated juice line links batching, deaeration, heat treatment, filler, cooling and packing under shared control, with the product path as one engineered system. It tightens footprint and labour versus standalone and gives consistent process control batch after batch — the right tier for a plant running one product family at mid output.

Integrated does not mean locked in: change parts and CIP still allow flavour rotation, but the control and piping are designed for it from the start.

5. Hot-fill combiblock

A hot-fill combiblock blows, fills and caps in one carousel, with the product path designed for hot-fill temperatures. It brings the volume-plant advantages — lightest bottle, smallest footprint, lowest labour per bottle — to juice, for plants with stable formats at volume. The bottle is heat-rated and designed with the preform supplier for the hot-fill duty.

The trade is the same as any combiblock: format lock-in and own-bottle commitment. Volume juice plants with one or two formats are the natural home.

6. The package decision

The package sets the machine: heat-rated PET demands a bottle designed for the fill temperature and vacuum, with the corresponding filler and capper spec; glass brings brand weight and heat tolerance at higher weight and cost. The decision comes before the configuration, because the filler and infeed differ between the two.

Send the bottle drawing and the cap to suppliers with the enquiry — the configuration quote follows the package, not the other way around.

7. The front end

The front end — batching, deaeration, homogenising for cloudy product, heat treatment — is shared across configurations and is where the drink is made. It is sized on the line output and the recipe, and it is the station where under-budgeting shows up first: a filler that starves for product runs at half its rating.

The front end also decides the flavour: deaeration protects it, homogenising stabilises pulp, and the hot path is kept short and controlled. The juice filling machine range shows the filler side; the front end is engineered with it as one system.
