Dehydration of the red chilli (Capsicum annuum L., costeño) using an indirect-type forced convection solar dryer

In the solar drying processes, two ranges of air velocity were established; high velocity was between 1.4 and 2.6 m/s, and low velocity was between 0.7 and 1.48 m/s. In both cases, a temperature between 31 °C and 45 °C was obtained. For the first range, the total drying time was 16 h, reaching a final moisture content between 0.057 kg of water/kg dry matter and 0.90 kg water/kg dry matter. For the second range, the time was 21 h, with a moisture content of 0.0611 kg of water/kg dry matter and 0.109 kg of water/kg dry matter.
