Abstract

The invention relates to a method in the drying of wet materials, such as sludges and bark mass, in which the materials to be dried are spread as a thin layer (16) on a base (12) and solar energy is used in the drying, by exposing the spread material to the effect of solar radiation and the wind. The drying is performed in rapid cycles, in periods of at most 3 days, on the basis of the forecast evaporation.
