Complete Juice Processing Plant Solutions

Once the product leaves the pasteuriser, it enters the most contamination sensitive phase of the juice processing line. Microbiological ingress between the cooler and the sealed container undoes the thermal work that came before it a fact that is easy to state and surprisingly easy to overlook in plant layout decisions.

Seppa's juice filling line operates with a sterile zone architecture where the fill head, container feed, and cap application all run under positive pressure filtered air. For hot fill products, fill temperatures between 85°C and 92°C are maintained within +1°C. Tight enough to ensure container sterilisation from the product temperature itself, but not so tight that thermal stress cracks PET or HDPE bottles. Pulpy products are managed through temperature controlled recirculation at the fill head, preventing settling between fill cycles without mechanical agitation that would damage fruit particles.

The transition to the juice packaging line brings a different set of requirements. Labelling, date and batch coding, secondary packaging, and palletising all have to execute without creating contamination points or mechanical stress on sealed containers. Seppa integrates these downstream stages including Kombopure aseptic fill cap units and end of line stretch wrapping into the same control system governing the upstream juice processing line. Traceability from finished pallet back to raw material lot is available without manual record reconstruction.

For aseptic cold fill applications, the juice filling line changes substantially. Containers are sterilised separately using hydrogen peroxide or UV treatment. The fill environment is maintained at ISO Class 5 or better. Fill temperatures match ambient or slightly below.

Seppa juice processing plants are designed for a low footprint layout where each stage is positioned to minimise transfer piping length. Shorter transfer lines mean faster CIP cycles, less product retained in dead legs between runs, and lower cleaning chemical consumption per litre of output.

•On waste reduction: pomace from pressing passes through a recovery system that captures residual juice before the solid fraction exits the line. Thermal energy from pasteurisation is recovered regeneratively at rates above 90%. Water consumption per litre of finished product is set as a target during system design and tracked continuously during production not estimated and forgotten.

The modular architecture of a Seppa juice processing line means capacity additions do not require taking down the existing line. A plant running 5,000 litres per hour can add a parallel pasteuriser and additional fill heads as volume grows. That is a planning advantage that compounds over time.

All product contact surfaces are 316L stainless, electropolished to Ra ≤ 0.8 µm. Gaskets are FDA compliant elastomers. No dead end pipework. No horizontal runs where condensate accumulates. These decisions are made at the design stage because correcting them after installation is expensive and disruptive.
