Delicias de Oaxaca is a solar food processing company located in Oaxaca, Mexico. Founders, Poli & Rodrigo, specialize in dehydrating various fruits and vegetables for sale.
They collect unsold fruits and vegetables from many farmers in the region. They peel them, cut them into thin slices and expose them to the sun and wind on the roof of their house. The simplest drying room there is: shelves protected from insects by a mosquito net.
In two days, they obtain tasty fruits that are 80% dehydrated. Then a short time in an electric dryer allows them to finish the work and make sure that the fruits can be preserved for months. For 30 kg (66 lbs) of fresh fruit, they still obtain approximately 5 kg (11 lbs) of dehydrated fruit.
