GELENEKSEL YÖNTEM VE MİKRODALGA İLE KUŞKONMAZIN (ASPARAGUS OFFICINALIS L.) KURUTULMASININ MODEL TABANLI KARŞILAŞTIRILMASI

Abstract

Bu çalışmada kuşkonmaz dilimleri farklı sıcaklıklarda geleneksel fırın veya farklı güç seviyelerindeki mikrodalga fırın ile kurutulmuştur. İki kurutma yöntemi arasındaki fark ve benzerliklerin araştırılmasında model tabanlı yaklaşım kullanılmıştır. Birincil ve ikincil modeller olarak sırasıyla Weibullian model ve doğrusal denklem kullanılmıştır. Birincil modele bütünleştirilen ikincil model, tek aşamalı yöntemle kuşkonmazın nem oranını tanımlamak için başarıyla kullanılabilmiştir. Her iki kurutma tekniği için uygun modeller elde edilmiştir, ancak mikrodalgada geleneksel kurutmadan daha yüksek uygunluk görülmüştür. Geleneksel kurutma eğrileri için kuyruklu, mikrodalga kurutma için s-biçimli eğriler gözlenmiştir. Mikrodalga kurutmanın en düşük gücünün (100 W) zaman parametresi (δ) değeri, geleneksel kurutmanın en yüksek sıcaklığının (90 °C) δ değerinin sadece üçte biridir, bu da mikrodalga kurutmanın geleneksel kurutmaya kıyasla zaman açısından etkili bir yöntem olduğunu göstermiştir.

MODEL BASED COMPARISON OF DRYING OF ASPARAGUS (ASPARAGUS OFFICINALIS L.) WITH TRADITIONAL METHOD AND MICROWAVE

Abstract

In this study, asparagus slices were dried with traditional oven and microwave oven methods. Model based approach was used to investigate the differences and similarities between two drying methods. Weibullian and linear equations were used as the primary and secondary models, respectively. Secondary model integrated into the primary model could successfully be used to describe the moisture ratio of asparagus in one-step procedure. Appropriate fits were obtained for both drying techniques, but microwave drying had slightly better fit than the conventional drying. Tailing was observed for the curves of traditional drying whereas sigmoidal curves were observed for microwave drying. The time parameter (δ) value of the lowest power of the microwave drying (100 W) was just one third of the δ value of the highest temperature of the traditional drying (90 °C) indicating that microwave drying was effective method in terms of time comparing to traditional drying.
