Jaggery is a traditional Indian sweetener prepared from sugarcane juice through evaporation process and considered as medicinal sugar due to its nutritional thereupatic properties. To improve the shelf-life of solid jaggery , making in form granules with moisture content 1–2% was recommended. A Polyhouse solar dryer for drying granular capacity 200 kg developed at Regional Agricultural Research...

Nanocrystalline TiO2 films, surface modified with Al3+, were manufactured by depositing a TiO2 suspension containing small amounts of aluminum nitrate or aluminum chloride onto conducting glass substrates, followed by drying, compression, and finally heating to 530 degrees C. Electrodes prepared with TiO2 nanoparticles coated with less than 0.3 wt % aluminum oxide with respect to TiO2 improved ...

Solar dried sewage sludge (SS) conversion by pyrolysis and gasification processes has been performed, separately, using two laboratory-scale reactors, a fixed-bed pyrolyzer and a downdraft gasifier, to produce mainly hydrogen-rich syngas. Prior to SS conversion, solar drying has been conducted in order to reduce moisture content (up to 10%). SS characterization reveals that these biosolids coul...

Solar drying and convective oven of cherry tomatoes (Solanum lycopersicum) were compared. The changes in the chemical parameters principal recorded during process. Drying curves fitted to several mathematical models, effects air temperature evaluated by multiple regression analyses, comparing previously reported models. Models for conditions indicated a final water content 30% (semidry products...

The main objective of this work is to determine the graphs relative humidity loss, and speed drying for green pepper, identify characteristic parameters influencing products with high content, establish satisfactory models that characterize kinetics. This experimental study was carried out using an indirect type a solar dryer, which functions in mode natural convection, intended thermal treatme...

The recent growth in the field of porous and nanometric materials prepared by non-conventional processes has stimulated the search of new applications of ZnO nanoparticulate. Zinc oxide is an interesting semiconductor material due to its application on solar cells, gas sensors, ceramics, catalysts, cosmetics and varistors. In this work, the precipitation method was used followed by controlled a...
