Increasing population and high cost of fuels have created opportunities for using alternate
energies for post-harvest processing of foods. Solar food processing is an emerging
technology that provides good quality foods at low or no additional fuel cost. A number of
solar dryers, collectors and concentrators are currently being used for various steps in food
processing and value addition. Keeping in mind this future requirement, a reliable, efficient
and low cost box type solar dryer was designed and developed at ICAR-Central Arid Zone
Research Institute, Jodhpur to dry perishable arid agricultural produce. In this paper, the
performance of box type solar dryer was evaluated with ber (Zizyphus mauritiana) fruit
because it is one of the popular seasonal fruit in India but highly perishable in nature. During
the performance evaluation, the maximum stagnation temperature inside the drying chamber
was observed to be 63°C and on loading with 3 kg ber it reduced to 49°C, while outside
ambient temperature was 27°C on a clear sky condition (from 10:00 h to 17:00 h) in the
month of January, 2016. During the drying process, moisture content of ber fruits reduced
from 80% (wet basis) to about 26% within 7 days. As compared with open sun drying, the
duration of drying was reduced by about more than 50% of the time.The efficieny of this
dryer was found to be 12.1%. The cost-benefit ratio was 3.84, which shows the potential
of using solar dryers in place of conventional dryers. The developed dryer was also used
to dry spinach and grated aonla and beetroot. Appearance, taste and flavour of ber in this
dryer was superior to that of open sun drying. The use of solar dryer will be a great boon
for farmers of arid region of Rajasthan.
