Hybrid ICDC solar dryers for granular materials–Recirculation type & Semi fluidized bed system

• Important features – Drying process occurs

simultaneously within three component of the machine (in pneumatic conveyor, collector-drying chamber, above hopper

– Utilize pneumatic conveyor which require less electricity ( 500 Watt to convey 500-600 kg of granular/hr

– Utilize 100% locally available renewable energy sources (Microhydro, solar, biomass, wind)

Artistic view floating OTEC (Ikegami et al, 2009)



ECONOMIC CONSIDERATIONS • OTEC needs high investment • Efficiency only 3% - low energy density – large heat transfer equipment therefore more cost
