Abstract

The shortest drying time was determined in the microwave convective dryer at 720 W power and ethyl oleate pre-treated samples. The longest drying time was determined in the convective dryer at 50 ºC. Control samples dried in an convective dryer at 50 ºC preserved the chroma color property of fresh. The drying data was best estimated by the Midilli-Küçük model. It was determined that the effective diffusion values ??varied between 3.14x10-9-2.35x10-7 m2/s. The highest SMER (0.0344 kg/kWh) value was determined in ethyl oleate pre-treated samples dried at 720 W microwave power. The lowest SEC (29.07 kW/kg) value was determined in the ethyl oleate pre-treated samples dried in a microwave dryer at 720 W power. The highest evaporation energy (2.70 kWh) is in the convective dryer. The highest energy efficiency was calculated as 7.20% in the same drying process.
