Abstract
India like other developing countries adopts many food preservation
technologies using fossil fuels. But the fossil fuel resource depletes over
the years and is non-renewable. Therefore, solar drying technology is
preferred as a sustainable method for food preservation. The present study
is aimed at a sustainable livelihood initiative for drying fruits and
vegetables through solar technology intervention using an indirect forced
convection type solar dryer. Such a dryer of 15 kg capacity has been
designed and fabricated for drying mangoes. Performance indicators such as
instantaneous collector efficiency, drying efficiency, drying rate,
coefficient of performance, heat utilization factor, and moisture content on
a dry basis are evaluated as 59%, 32.25%, 0.15178 kg/hr, 0.77, 0.229, and
2.55 respectively by considering maximum outlet collector temperature,
drying chamber temperature and atmospheric temperature. Economic indicators
such as payback period and cost-benefit ratio are also evaluated as 1.439
and 2.0008 respectively. The dryer can be used by rural people of Odisha for
earning their livelihood.
