Industrialization at LIS by Lesaffre



••• Electrostatic spray-drying
under nitrogen with POLARDRY™

Electrostatic spraying

Strong reduction of surface oil for emulsion drying.

Solvant évaporé

Low temperature drying under nitrogen

Agglomération en une étape


LIS by Lesaffre is expanding its range of gentle & protective drying services with FluidAir’s PolarDry® technology, now available in Europe at an industrial scale..

This disruptive technology is particularly suitable for products requiring advanced microencapsulation, such as aromatic molecules, colors or essential oils.

It is also a technical and economical alternative to freeze-drying, as it allows low-temperature drying of heat-sensitive products such as live microorganisms, probiotics and certain proteins.

A laboratory scale pilot is also available at the Powder Studio™, a co-development laboratory located in Rennes. Electrostatic spraying under nitrogen causes a restructuring of the droplet components allowing:

  • Excellent microencapsulation with fewer active ingredients on the surface.
  • Drying at lower temperatures.
  • Protection against oxidation of active ingredients during drying.
  • One-step micro granulation and functionalization of the powder.

••• Spraying
high viscosity and pOrosification

Come test the only EPT™ pilot available in Europe, resulting from a partnership with Clextral.

EPT™ allows spray drying of semi-pasty products which are non-sprayable with standard technologies available on the market.

The high concentration of dry matter of the product as well as the injection of a gas to form a foam before the spray, allow for the optimization of the drying stage (time and temperature).

In addition, this patented technology produces a highly porous powder, thus improving properties such as flowability, rehydration, dispersibility, etc.

Passing through the extruder also optimizes inline additions of sensitive components.

EPT™ is a patented technology that enables:

  • Spraying of high viscosity products
  • Drying of high concentration products
  • Obtaining particularly porous powder particles thus improving their flowability and rehydration.
  • Powder functionalization for various applications

••• flowfocusing®
encapsulation and capsule 2.0

Come test this innovative technology at the Powder Studio™ and benefit from our expertise and facilities on a laboratory and pilot scale.

FlowFocusing® patented technology allows the formation and gentle drying of custom-made capsules for your sensitive components.

Benefits of FlowFocusing® technology include:

  • Particles of similar size (mono-disperse and dust-free) thanks to an innovative spray nozzle.
  • Enhanced microencapsulation with “Core-Shell” capsules formation
  • Very low drying temperatures thanks to a laminar flow process.
