Microwave Drying of Quince Slices
Bu çalışmada, ayva dilimlerinin nem oranı, kuruma hızı ile mikrodalga kuruma karakteristikleri rapor edilmiştir. Ayva dilimleri fan destekli mikrodalga kurutucuda kurutulmuşlardır. Ayva dilimlerinin kuruma süresi ve kurutma hızı üzerinde mikrodalga kurutmanın (180, 360, 540, 720 and 900W) etkileri araştırılmıştır. Ayva dilimleri 3,75 g su/g kuru madde ilk nem içeriğinden 0,12 g su/g kuru madde son nem içeriğine kadar kurutulmuşlardır. Mikrodalga kurutma sistemi içerisinde, 5 mm kalınlıkta dilimlenen ayva dilimleri 180, 360, 540, 720 ve 900 W mikrodalga güç seviyelerinde kurutulmuştur. Mikrodalga kurutma denemeleri süresince, dilimler tartılmış ve her 1 dakikada elle ölçümler kaydedilmiştir. Kurutma verileri, 10 farklı matematiksel modellere (Newton, Page, Henderson ve Pabis, Logaritmik, Midilli-Kucuk, Wang ve Singh, iki terimli, Verma, iki terimli üssel, difüzyon yaklaşımı) uygulanmıştır. Tüm kuruma modelleri içerisinde, en uygun kuruma modeli, Midilli-Kucuk model eşitliği bulunmuştur.
Ayva Dilimlerinin Mikrodalga ile Kurutulması
In this research, microwave drying characteristics on moisture ratio, drying rate of quince slices were reported. Quince slices were dehydrated in a fan assisted microwave oven dryer. The effects of microwave drying (180, 360, 540, 720 and 900W) on drying time, drying rate of quince slices have been investigated. Quince slices were dried from 3.75 g water/g dry matter initial moisture content to 0.12 g water/g dry matter final moisture content. In the microwave drying system, quinces sliced into 5 mm thickness were dried at 180, 360, 540, 720 and 900W microwave drying powers. During microwave drying experiments, slices were weighted and data recorded manually per 1 minute. The drying data were applied to nine different mathematical models, namely, Newton, Page, Henderson and Pabis, Logarithmic, Midilli-Kucuk, Wang and Singh, Two Term, Verma, Two Term Exponential, Diffusion Approach Equation Models. It was found that the Midilli-Kucuk model described the drying curve satisfactorily in all drying methods.
