Installation and method with improved performance for forming a compact film of particles on the surface of a carrier fluid

An installation for forming a compact film of particles on a surface of a carrier fluid, the installation comprising:

• a zone acting as a carrier fluid reservoir;
• an inclined ramp situated extending from the zone acting as a reservoir and whereon the particles can circulate gravitationally;
• a particle storage and transfer zone situated extending from the inclined ramp;
• means for moving the carrier fluid to make the carrier fluid circulate from the zone acting as a reservoir to the particle storage and transfer zone, via the inclined ramp;
• means for dispensing the particles in solution, configured to dispense the particles on the surface of the carrier fluid in the zone acting as a reservoir;
• and
• means for raising a level of the carrier fluid by capillary effect, arranged at a junction between the zone acting as a reservoir and the inclined ramp.
