Drying experiments were performed in May 2010. Average temperatures recorded
during drying experiments in the collector part of the solar dryer, at the inlet and exit of
the spouting bed and in the surrounding were given in Table 1. As it can be seen from
the table, ambient temperature change between 20 and 27.4 C while temperature of the collector part of the solar dryer changed between 40 and 68 ◦C during the experiments.
