Abstract

Strawberry drying was investigated experimentally and numerically in this study. In the experiments, samples of strawberry slices with 1 cm thicknesses were used to investigate the effect of the drying air velocity. 5-hour experiments were conducted for three different velocities (0.5, 1 and 2m/s) at 70°C air temperature. It was observed that increasing the drying air velocity up to 2 m/s decreased the drying duration by 17% on average. Moreover, the data obtained from the experimental study were compared to the numerical results. The results were found compatible with each other. Finally, the effect of air temperature and product thickness on drying was examined numerically.

Özet

Bu çalışmada çilek kurutulması deneysel ve nümerik olarak incelenmiştir. Deneylerde kurutma hava hızının etkisini incelemek için 1 cm dilim kalınlığındaki çilek örnekleri kullanılmıştır. 70°C hava sıcaklığında üç farklı hız için (0,5-1 ve 2m/s) 5 saatlik deneyler gerçekleştirilmiştir. Kurutma hava hızının 2 m/s ye çıkarılmasının kurutma süresini ortalama %17 azalttığı görülmüştür. Ayrıca deneysel çalışmadan elde edilen veriler nümerik sonuç ile karşılaştırılmıştır. Elde edilen sonuçların birbiri ile uyumlu olduğu görülmüştür. Son olarak hava sıcaklığının ve ürün kalınlığının kurutma üzerine etkisi nümerik olarak incelenmiştir.
