The socio-economic status of arid-zone people can be enhanced by value addition to kachri fruits. The establishment of solar tunnel dryers in arid regions could not only enhances the quality of dried products but also increases future real farm income. The kachri were totally sheltered from dust, insects, and rain while drying in the solar tunnel drier. Among the applied kinetic models, the Page and Midilli kinetic models accurately depicted the solar drying behaviour of kachri. The sensory evaluation of dried kachri products showed that dried product had a good grade for human consumption and can be helpful to keep the population healthy and nutritionally secure compared to the expensive off-season vegetables. The CO2 mitigation potential of the dryer during its lifespan was found 77.05 tons for drying of kachri.
