The unpredictable rise and frequent scarcity of fossil fuel accelerated the continuous search for an alternative power source. Solar is one of the renewable and sustainable sources of power that attracted a large community of researchers from all over the world. This is largely due to its abundant in both direct and indirect form. As such the development of efficient and inexpensive equipment f...

In this study, an air heated solar collector (AHSC) dryer was designed to determine the drying characteristics of the pear. Flat pear slices of 10 mm thickness were used in the experiments. The pears were dried both in the AHSC dryer and under the sun. Panel glass temperature, panel floor temperature, panel inlet temperature, panel outlet temperature, drying cabinet inlet temperature, drying ca...

In this study, coriander leaves were subjected to three different drying techniques; direct sun, shade, and using an indirect solar dryer. the developed dryer, hot air obtained from a black-body collector was pushed by blower powered panel, sent chamber with multiple trays for thin-layer drying. Experiments conducted summer winter seasons, temperature relative humidity variations in measured da...

The current study focuses on the performance of Solar Greenhouse Dryer for drying grapes raisin making in and Open sun condition Western Maharashtra. Maharashtra state ranks first production grapes, probably produces nearly 800 thousand tons every year. major wastage is due to low sugar content, glossy appearance, shrinkage, excess water berry, scorching size variation. Therefore, there a need ...

Maize is an important cereal produced for food and feed its nutritional composition viability could be affected when subjected to inappropriate drying conditions. This study investigated the effects of temperature on proximate maize grains dried at different levels in a solar biomass hybrid dryer. Proximate analysis was performed using standard A.O.A.C. methods. Germination test done sterilized...

a thin layer solar drying method was compared with a traditional method (sun drying) of paddy drying, with their effects on quality characteristics of two varieties of iranian rice (kamphiroozi and sazandegi) studied. solar drying process was conducted in a passive, mixed mode type solar dryer at about 50ºc for 90 minutes. in sun drying method this process took 8-10 hours at a mean temperature ...

The purpose of this study was to determine the performance a hybrid dryer by combining utilization solar energy (solar dryer) and biomass power sources. Utilization thermal sources maximizing heat radiation which are absorbed directly into drying chamber in form transparent house with ventilation holes for fresh air enter moist exit. This process will produce hot circulation (convection) contin...
