Thermal modelling of two-tray reverse absorber cabinet dryer with glass cover

SYNOPSIS Different kinds of solar dryers have been developed based on the scientific utilisation of solar energy for crop drying purposes. In this paper, a two-tray reverse absorber type cabinet dryer having a glass cover for the direct entry of solar radiation from the top has been proposed. It combines the features of a normal cabinet dryer and the reverse absorber cabinet dryer proposed by many researchers. Thermal modelling has been done to examine the effect of the glass cover on aspects related to crop drying.
