Abstract

The influence has been studied of the absorbing layers to the efficiency of solar drying chamber. Proposed solar drying chamber walls are composed of translucent coating from outside and absorbing layers are placed its inside. A technique is used for calculating the effective value of transparent wall´s transmittance and investigated average system efficiency with effective value of wall transmittance for solar radiation. Also a model is proposed for evaporation heat flux from drying product surface at any temperature.
