EnDev promotes food processing technologies
such as solar dryers among small and medium
enterprises (SME) and farmers. The demand is
increasing. Throughout the different regions
of the Altiplano (Andean dry highlands), at least
40 solar dryers have been constructed and
installed for the production of Andean prod-

AFRUCH, for example, increased its income by
