Abstract

In this research work, drying characteristics of zucchini slices were investigated using a microwave conveyor dryer. The drying experiments with 5 mm, 10 mm, 15 mm thickness were carried out at 1.5 kW and 2.1 kW. The results showed that energy consumption and drying time decreased considerably with decreasing conveyor speed. Energy consumption was measured between 2.014-3.520 kWh. Particularly five empirical models were determined in defining the microwave drying behavior of zucchini slices by statistical analysis. The Page Model gave a better result for all drying experiments. The coefficients of the models were determined by non-linear regression analysis and the diffusion coefficient was calculated. The diffusion coefficients were found between 1.682x10-7- 2.690x10-6 m2/s. A color analysis was carried out to investigate the effects of microwave dryer on zucchini color quality. L* values at 2.1 kW and 0.210 m/min dried samples with 5 mm thickness were determined as the highest value.

Özet

Bu çalışmada mikrodalga konveyör kurutucu kullanarak kabak dilimlerinin kuruma davranışı araştırılmıştır. Kuruma deneyleri 5 mm, 10 mm ve 15 mm dilim kalınlıklarında, 1,5 kW ve 2,1 kW güçlerinde gerçekleştirildi. Elde edilen sonuçlara göre konveyör hızının azalması ile enerji tüketimi ve kuruma zamanı azalmıştır. Enerji tüketimi 2,014-3,520 kWh arasında ölçülmüştür. Kabak dilimlerinin istatiksel olarak kuruma davranışı beş deneysel model ile tanımlanmıştır. Tüm kuruma deney sonuçlarına göre Page model daha iyi sonuç vermiştir. Non-lineer regression analizi ile modeldeki katsayılar ve difüzyon katsayısı belirlendi. Difüzyon katsayıları 1,682x10-7- 2,690x10-6 m2/s arasında hesaplandı. Mikrodalga kurutucunun kabağın renk kalitesindeki etkisi göre en yüksek L* değeri 5 mm dilim kalınlığında, 2,1 kW ve 0,210 m/dk konveyör hızında belirlenmiştir.
