Date palm (Phoenix dactylifera L.) fruits are widely grown in rural areas of arid Rajasthan of
India. The grown date palm fruits are generally dried in forced convection mode. However, given the
socio-economic status of farmers, dryer facility affordability has become crucial. Additionally, there is
a critical need for a simple winnower, especially with its operation. To address the highlighted issues
with the dryer and winnower and given a location already receiving abundant solar radiation, a solar
photovoltaic (PV) winnower cum-dryer was designed and developed. The developed winnower
cum-dryer was tested in actual conditions to realize the performance. First, the drying experiment
for dehydrating date palm fruits and, second, the winnower experiment for separating grains from
straw were carried out. The date palm fruits used for experimentation have a moisture content of
65% on a wet basis. During the drying trial, the dryer reduced this moisture content by 39% in 6 days.
In contrast, in the open sun drying, it took 8 days. The drying chamber’s temperature gradient was
reduced to 2–3 degree C from 6–8 degree C in the system provided with a preheater, resulting in uniform drying. The observed effective moisture diffusivity and the dryer’s efficiency are 4.34 10􀀀9 m2 s􀀀1 and
16.1%, respectively. A high IRR of 57.4% and a shorter payback period of 2.10 years were found in the
economic analysis, indicating that the dryer is cost-effective. The winnower operation results suggest
that about 200–300 kg grains could be separated daily when used as a winnower without natural
wind. Overall, the developed winnower cum-dryer produced better-quality dried date palms in a
shorter time than open drying by efficiently using solar energy and separating the grains from straw
to enhance the utility throughout the year.
