Bu çalışmada 5mm dilimindeki patatesin mikrodalga bantlı kurutucuda mikrodalga gücünün (1500W ve 2100W) ve bant hızının (0,175, 0,210 ve 0,245 m/dak) kurutma zamanı, renk değişimi ve enerji tüketimine etkisi araştırıldı. Elde edilen sonuçlara göre mikrodalga gücünün artması ve bant hızının azalması ile enerji tüketimi azalmıştır. Dokuz adet kurutma modelinin uygunluğunu belirlemek için deneysel ve teorik nem oranları dikkate alınarak korelasyon katsayısı (r), standart hata (es) ve (χ2) hesaplandı. Tüm kurutma şartları için Page modelin en uygun model olduğu belirlenmiştir. Efektif difüzyon katsayısı 2,958.10-7 ve 3,587.10-6 m2/s aralığında hesaplanmıştır. Kurutma süresince en az enerji 0,175m/dak ve 2100W gücünde belirlenmiştir.
