Abstract

This study examines the impact of drying Levant hazelnut samples, including husk and shell, using hot air heated by solar panels at a constant speed of 6 m/s. The study also investigates the impact of collector irradiation absorption surface geometries on hazelnut drying time.
A solar collector with four types of air duct geometry was used to dry hazelnuts. The radiation-absorbing surface of the air duct was manufactured flat, and three different trapezoidal geometries (30, 45 and 60 angles) were used. The mass losses of hazelnuts were measured and determined at regular intervals. In addition, the total phenolic content, the DPPH radical scavenging activity, the FRAP, the free fatty acid content, the peroxide value and the moisture content were measured. For the purpose of comparison, some of the products have been dried by means of unheated air at ambient temperature.
The pre-drying process (withering process) to separate the hazelnuts from husk, only took 1.5 days (14 hours excluding night). In these systems, the shelled fresh hazelnuts, separated from the husk, fell below the equilibrium moisture content of 6% in 2 days (except for 18 hours at night). It was found that the most suitable collector geometry for all the parameters studied in the drying of hazelnuts with solar collectors was 45 degrees, and that other geometries could be used in terms of food properties.

Abstract

Bu çalışma, güneş panelleri tarafından 6 m/s sabit hızda ısıtılan sıcak hava kullanılarak kabuk ve zuruf dahil Levant fındık örneklerinin kurutulmasının etkisini incelemektedir. Çalışmada ayrıca kolektör ışınım absorpsiyon yüzey geometrilerinin fındık kuruma süresi üzerindeki etkisi de araştırılmıştır.
Fındığı kurutmak için dört tip hava kanalı geometrisine sahip bir güneş kolektörü kullanılmıştır. Hava kanalının radyasyon emici yüzeyi düz olarak imal edilmiş ve üç farklı trapez geometrisi (30, 45 ve 60 açı) kullanılmıştır. Fındıkların kütle kayıpları düzenli aralıklarla ölçülmüş ve belirlenmiştir. Ayrıca, toplam fenolik içeriği, DPPH radikal süpürme aktivitesi, FRAP, serbest yağ asidi içeriği, peroksit değeri ve nem içeriği ölçülmüştür. Karşılaştırma amacıyla, bazı ürünler ortam sıcaklığında ısıtılmamış hava yoluyla kurutulmuştur.
Fındığın kabuğundan ayrılması için yapılan ön kurutma işlemi (soldurma işlemi) sadece 1,5 gün (gece hariç 14 saat) sürmüştür. Bu sistemlerde, kabuğundan ayrılan kabuklu taze fındıklar 2 gün içinde (gece 18 saat hariç) denge nem içeriği olan %6'nın altına düşmüştür. Fındığın güneş kolektörleri ile kurutulmasında çalışılan tüm parametreler için en uygun kolektör geometrisinin 45 derece olduğu, gıda özellikleri açısından diğer geometrilerin de kullanılabileceği tespit edilmiştir.
