Mixed-mode, natural circulation, solar energy dryers combine the features of the integral-type and the distributed-type natural circulation solar energy dryers.
In this case, the combined action of solar radiation incident directly on the product to be dried and the air heated in a solar air collector provide the necessary heat required for the drying process. A mixed-mode, natural circulation solar energy dryer has the same structural characteristics as the distributed type, i.e., a solar air heater, a separate drying chamber, and a chimney; in addition, the drying chamber walls are glazed so that the solar radiation can reach the product directly as in the integral-type dryers, as shown in Figure 7.16.
