Development of an optimal mechanism for a solar-air collector for drying thermolabile products

Abstract The article presents theoretical and experimental studies about the alternative construction of energy-efficient solar air collector that generates heat based on alternative energy sources for the drying process of agricultural products. In particular, the geographical latitude of the place (φ), the angle of elevation of the sun to the horizon (h°), the angle of deviation of the sun (δ), and τ the interrelationships between the sun’s hour angles (τ) were studied. The patterns of changes in the wet air and dry air parameters entering the solar air collector were analyzed. The mechanism of efficient use of the heat generated in the solar air collector was developed. The kinetics of the process of drying spices at low temperature was studied.B NNBB. 1
