Resumo(s)
This article presents an overview of passive solar dryers, an
ancient technique that may be revived for food drying capacities below
one ton/day. The art of dehydrating food has existed for centuries and
was developed to preserve food by extracting its water content, thus
delaying its natural deterioration. This article reviews traditional solar
dryers and proposes a verification parameter k, parametrising the solar
collector’s size by the drying capacity. The modelling and parametrisa tion of the k constant allowed the evaluation of the examples of tra ditional models from the literature systematically. Results showed that
80% of the evaluated constructed solar dryers might underperform due to
lower solar collecting surfaces than those projected by the k parameter.
