La ciencia detrás del secado solar

Abstract

Solar drying is a food preservation technique that has become technologically advanced and evolved as a sustainable alternative to electric or fossil fuel methods. Indirect solar drying systems allow food to be dehydrated using air heated by solar radiation, reducing post- harvest losses and contamination risks. These devices, affordable for small producers, combine heat and mass transfer processes to ensure a final moisture content of less than 10%, extending food shelf life. Their implementation contributes to reducing waste and associated greenhouse gas emissions.
