Sıcak Havayla Kurutulan Enginar (Cynara cardunculus L. var. scolymus) Dilimlerinin Kuruma Eğrilerinin Tanımlanmasında Yeni Bir Modelin Geliştirilmesi ve Mevcut Modellerle Kıyaslanması

İlk nem seviyesi yaş baza göre % 85.9 (±0.03) olan 100 (±0.03) g ağırlığındaki ve 4 (±0.1) mm kalınlığındaki enginar (Cynara cardunculus L. var. scolymus) dilimleri yaş baza gore nem seviyesi % 9.52 (±0.005) oluncaya dek 50, 75 ve 100 °C sıcaklıktaki ve 1 m s-1 hıza sahip hava akımıyla kurutulmuşlardır. Kurutma işlemleri 50° C’de 300 dakika, 75°C’de 210 dakika ve 100°C’de ise 130 dakika sürmüştür. Bu çalışmada kurutma literatüründe daha önce çeşitli araştırmacılar tarafından tanımlanmış ve deneysel, yarı deneysel ve teorik olarak sınıflandırılmış 21 farklı ince tabaka kurutma modelinin yanı sıra Midilli ve ark. (2002) eşitliğinden türetilmiş olan ve Alibaş Yaklaşımı olarak adlandırılmış yeni bir kurutma yaklaşımı ile deneysel olarak elde edilen veriler modellenmiştir. Deneysel olarak elde edilen veriler ile tahmin verileri arasındaki ilişkileri gösteren tanımlama katsayısı (R2), standart hata değeri (SH), ortalama karesel hata (ERMS) ve ki kare (χ2) değerleri hesaplanmıştır. Tanımlama katsayısının (R2) en büyük olduğu, standart hata (SH), ki kare (χ2) ve ortalama karesel hata (ERMS) değerlerinin ise en küçük olduğu model en iyi model olarak seçilmiştir. Buna göre çalışmada kullanılan üç farklı sıcaklıkseviyesinde de elde edilen deneysel verilere en yakın sonuçları veren model Alibaş Modeli olarak belirlenmiştir
