Abstract

Dehydrated cabbage leaf slabs introduce a practical and easy-prepared dried form of foods and have a potential for industrial scale productions. This study aims to provide drying curves of 10x5cm cabbage leaf slabs at different drying temperatures and times and to model drying behavior empirically. Cabbage leaves were blanched in boiling water for 2 min and convectional dried at different temperatures 40, 50, 60 and 70°C . All experiments were triplicated. Cabbage leaf slabs were weighted in 10min intervals during 90min total drying time. Drying curves were produced and modelled empirically. Results indicated that the weight loss increased by increasing drying temperature. Also, increase in drying time resulted in an increase in weight loss at the same drying temperature. Exponential model was satisfactorily applied to drying temperatures in the range of 40-70oC R2>0.95

Plaka Şekilli Beyaz Lahana Yapraklarının Kuruma Davranışının Modellenmesi

Abstract

Çalışma farklı kurutma sıcaklığı ve süresinde konvektif kurutulan 10x5 cm'lik plaka şekilli lahana yapraklarının kuruma eğrilerinin oluşturulmasını ve kuruma davranışının ampirik modellenmesini amaçlamıştır. Beyaz lahana yapraklarının pratik ve hazırlama kolaylığı sunan plaka şekilli kurutulmuş hale getirilmesi ile ticarileşme potansiyeli olan kurutulmuş ürün eldesi sağlanmıştır. Lahana yaprakları kaynar suda 2 dakika haşlanarak farklı sıcaklıklarda 40, 50, 60 ve 70°C üç paralel ve üç tekrarlı olarak konveksiyonel kurutulmuştur. 90 dakikalık toplam kurutma süresi boyunca 10 dakikalık periyotlarla lahana yapraklarının ağırlıkları kaydedilmiş, kuruma eğrileri oluşturulmuş ve kuruma davranışları ampirik modellenmiştir. Kurutma sıcaklığı arttıkça ağırlık kaybı artmış, yine aynı kurutma sıcaklığında kurutma süresinin artması ağırlık kayıplarını arttırmıştır. 70-90°C sıcaklık aralığında üstel modelin başarıyla R2>0.95 kullanılabileceği görülmüştür
