Abstract :

Providing new solutions to control wet waste is one of the most important issues in maintaining public health. A good solution in order to manage of food waste for benefits of environmental, economic and agriculture is drying. Drying will reduce waste and increase preservation by reducing moisture. In this regard, two types of methods for drying food waste with conventional tray pattern, and tray with Central and lateral airflow pattern in cabinet dryer were studied. The effect of three temperatures of 50, 60 and 70 ° C and three velocities 1, 1.5 and 2 m / s with thickness of 3 cm on the energy consumption were investigated. In addition, drying kinetics and drying intensity diagrams were extracted. The results showed that the in the central and lateral airflow pattern, temperature is an important factor that affects in the drying of food waste. The energy consumption in the tray with central and lateral airflow pattern is more than the conventional tray pattern.
