Bu çalışmada zencefilin akışkan yataklı kurutucuda kuruma kinetiği incelenmiştir. Yaş baza göre başlangıç nemi %88-89 olan zencefil kökleri, 2 mm kalınlığında dilimlenmiş ve % 4-5 nem içeriğine kadar kurutulmuştur. Kurutma havasının sıcaklığı, hızı ve bağıl neminin kuruma kinetiğine olan etkisini incelemek üzere, deneyler farklı kurutma havası (40, 50, 60 °C) sıcaklıklarında ve farklı (3 ve 4 m/s) hava hızlarında gerçekleştirilmiştir. Kurutma esnasında belli zaman aralıklarında alınan numunelerin kuru baza göre nem değerleri ölçülmüş ve daha sonra belirlenen nem oranları kullanılarak difüzyon katsayıları hesaplanmıştır. Elde edilen deneysel sonuçlar, kurutma havası sıcaklığının, hızının ve neminin kuruma hızında oldukça etkili bir parametre olduğunu göstermiştir. Ayrıca deneysel veriler literatürde var olan ince tabaka kuruma kinetiği modelleri ile karşılaştırılmış, verilerin Page modeli ile uyumlu olduğu görülmüştür.
