Abstract (EN):
Low temperature drying systems are commonly used for the drying of agricultural products. The ones which use solar energy as a heat source have been developed and diffused in the past few years.
The evaluation of drying systems1 performance involves consideration of all the components of the system: solar collectors, driers, etc. The correct understanding and modelling of drying phenomena is of fundamental importance to the system’s simulation. This way, the physical mechanisms involved in a drying process are referred, and methods for predicting the drying behaviour of materials are presented.
The influence of various drying parameters — drying temperature, velocity, direct solar radiation incidence — are analysed, for a forced convection system. For a given solar drying system, the contribution of solar energy is quantified.
