In order to dry food and agriculture waste; a cabinet dryer was designed, constructed and evaluated. An axial fan with an air volume of 310 m3/h, 2800 rpm, and 110 Pa was selected to supply airflow in the dryer and heater by heating power 2.7 Kw. A thickness of 3cm for samples was selected to evaluate the drying process. The selected variables were included three levels of air velocity of 1, 1.5, and 2 m/s and three air temperature levels of 50, 60, and 70°C. Drying time and dryer energy consumption during food waste drying were obtained. The results showed that the dryer has a significant effect on energy consumption. Energy consumption decreased with increasing drying temperature and air velocity.
