Elea PEF Advantage systems blanch vegetables up to 50% faster, improve cutting, produce less breakage and provide greater control over texture.

Pulsed Electric Field solutions from Elea transform vegetable processing, enhancing your production line, improving the quality of your product and providing savings in time and energy.

  • Curved asparagus spear on a dark surface

    Greater product flexibility

    PEF treated raw materials have the strength and flexibility to maintain better structural integrity.

  • A green bean tied in a knot on a dark surface.

    Texture modification

    In combination with mild thermal treatment PEF can harden the product, providing full control over the final texture.

  • A sliced piece of beet on a hand

    Better colour retention

    The reduction in blanching time causes less thermal damage to the product and results in an overall better colour.

  • Sliced white mushrooms on a dark surface

    Better cutting & less breakage

    PEF softening improves cutting. Improved slicing also results in less waste and breakage.

Discover the right Elea PEF Advantage system for your vegetable line

Designed for quick and seamless integration into your existing production line, our systems are built for 24/7 operation and can withstand extreme conditions with minimal disruption.

Large-scale production

  • The largest systems in the Elea belt range deliver unmatched robustness, power efficiency, safety, and ease of use. Built with premium stainless steel and engineered to the highest standards by our German team, these systems are designed for 24/7 operation in the most demanding environments.

  • We build a range of different models for large-scale production.

    The PEF Advantage B 10-320: 0 - 15 t/h.
    The PEF Advantage B 100-550: 0 - 32 t/h.
    The PEF Advantage B 1000-850: 0 - 100 t/h.

The best PEF solution for your vegetables

We have deployed close to 300 Elea PEF systems worldwide, serving some of the most renowned food producers. Each Elea PEF Advantage system is designed for 24/7 production and built to withstand extreme operating conditions.

Elea PEF Advantage systems have a fully flexible processing capacity.

Able to process a single potato or a full load with no impact on the PEF treatment and putting you fully in control of your production planning.

All Elea systems are designed to be easily and fully integrated into your existing production line with minimal disruption.

Elea PEF Advantage system benefits for the vegetable production line

Elea's Pulsed Electric Field solutions revolutionize vegetable processing by optimizing your production line, enhancing product quality, and reducing time and energy costs.

  • PEF pre-treatment compensates for natural variations in the quality of the raw material, allowing new and normally more difficult to process varieties to be used in production.

  • Easier cutting due to PEF softening provides greater yields, improved cut consistency and longer knife durability. Improved slicing also results in less waste and breakage.

  • Due to the open cell structure induced by PEF, enzymes are more accessible. Therefore, the enzyme inactivation can be improved and, consequently, can shorten the blanching time.

  • The electroporation of the cell membrane improves mass transport through the product, accelerating water removal and reducing drying times.

  • The open cell structure and reduced turgor pressure result in a more flexible and robust raw material that is less likely to break during canning.

  • PEF treatment results in a greater distribution of water on the product surface prior to freezing, leading to less clustering.

Improved cutting, greater flexibility, less breakage, and texture modification

  • Comparison of untreated and PEF-treated sliced mushrooms on a dark surface.
  • Two green beans shown, with one labeled "Untreated" and the other "PEF treated," demonstrating flexibility by being tied in a knot.

PEF gently opens the pores in the vegetables cell membrane, transforming the structure of the product. It’s a clean, gentle, targeted process. After treatment, the potato is smoother, softer, has better strength and flexibility.

Pulsed Electric Field induces electroporation, opening the vegetable cells. This increases mass transport, resulting in a smoother surface and more flexible product.
