Effect of microwave power on drying behavior and essential oil yield of microwave dried Eucalyptus camaldulensis Dehnh. leaves

Öz:
In this study, the aim was to microwave dry Eucalyptus camaldulensis Dehnh. leaves, while evaluating the role of microwave power regarding drying behavior, drying rate, drying time, drying kinetics, moisture diffusivity, energy consumption and essential oil yield. The leaves were dried by microwave at four different power levels (180, 360, 600 and 720 W). The results found that increasing the increment power levels decreased the time for drying and increased the drying rate. To fit the experimental data, nine widely used thin layer drying kinetics models were used. The analysis of the drying curves indicated that the Page model was the most appropriate. There was a significant difference in moisture diffusivity between 2.36×10-11 and 11.45×10-11m2/s. Increasing microwave power was led to an increase in moisture diffusivity. In accordance with the Arrhenius equation, a value of 7.4225 W/g was determined for the activation energy. In terms of specific energy consumption, the results ranged from 8.56 to 9.93 kWh/kg. When leaves were dried with a microwave power of 180 W, the maximum yield of essential oil was obtained.

Mikrodalga gücünün mikrodalgada kurutulmuş Eucalyptus camaldulensis Dehnh. yapraklarının kuruma davranışı ve uçucu yağ verimi üzerine etkisi

Öz:
Bu çalışmada, Okaliptüs camaldulensis Dehnh. yapraklarının mikrodalga kurutulması bu esnada mikrodalga gücünün kuruma davranışı, kuruma hızı, kuruma süresi, kuruma kinetiği, nem diffüzivitesi, enerji tüketimi ve uçucu yağ verimi üzerindeki etkisinin değerlendirilmesi amaçlanmıştır. Yapraklar dört farklı mikrodalga güç seviyesinde (180, 360, 600 ve 720 W) kurutulmuştur. Sonuçlar, artan güç seviyelerinin kuruma süresini azalttığını ve kuruma hızının arttığını göstermiştir. Deneysel veriler, yaygın olarak kullanılan dokuz ince tabaka kurutma kinetiği modeline uydurulmuş ve Page modelinin kurutma eğrilerine uyan en iyi model olduğu bulunmuştur. Efektif nem diffüzivitesi 2.36×10-11–11.45×10-11m2/s aralığında bulunmuştur. Artan mikrodalga gücü, nem yayılımında bir artışa yol açmıştır. Aktivasyon enerjisi Arrhenius denklemine göre 7.4225 W/g olarak belirlenmiştir. Spesifik enerji tüketimi 8.56 ile 9.93 kWh/kg arasında değişmektedir. Maksimum uçucu yağ verimi, 180 W mikrodalga gücünde kurutulan yapraklardan elde edilmiştir.
