The modular pilot line is an open access infrastructure for companies, which was implemented for the production of high quality (multi-)functional nanocomposites (supra-particles) on a pilot scale. Essential elements of the pilot line in Wuerzburg (Germany) are the particle synthesis in batches up to 100 litres (5 kg of nanoparticles per hour), modification and separation methods such as semi-continuous operating centrifuge and in-line analysis and techniques for the uniform and agglomeration free incorporation of nanoparticles into composites. The 100 L reactor can be stirred, fast heated, fast cooled and also used under reflux. It is also possible to apply pressure and low vacuum to the reactor. Complimentary to this high volume batch reactor, continuous reactions can be carried out in an ultrasonic dispersion / reaction unit. Supplementary to the semi continuous centrifuges, lab to technical scale spray-dryers can be used for separating particles from the solvent.
