dc.description.abstractBoth a heat pump and solar dryer were designed and manufactured. They were experimentally analyzed by drying apples, and a comparison was made between the two. Apples were sliced 4 mm thick, and dried from 4.8 (g water/g dry matter) moisture content to 0.18 (g water/g dry matter) at 3.3 kg/m(2)s-2.4 kg/m(2)s mass air velocity for 15 h in a heat pump dryer. Apples were also dried at the range of 3.3 kg/m(2)s and 2.9 kg/m(2)s mass air velocity from 4.8 (g water/dry matter) moisture content to 1 (g water/g dry matter) moisture content in the same period in a solar dryer. Effective moisture diffusivity was found to be 2.36 x 10(-8) m(2)/s in the heat pump dryer, and 1.03 x 10(-8) m(2)/s in the solar dryer. For both systems, the moisture ratio was analyzed with the Statgraphic program by using semi-theoretical models and compared to the empirical values. Correlation coefficients of the equations were calculated and standard error of estimation (SEE) and R-2 values were obtained.en_US
