Drying of Apricot with Solar Energy in Cabin Type Dryers

Öz

One of the most important techniques for safe storage of foods is drying. For this purpose, different drying methods were developed and used in food preservation. In long term storage, the main purpose of drying applied to foodstuffs is to prevent spoilage. Thus, the moisture of the product is reduced and microbial growth can be prevented. When the volume of the product decreases with the drying process, the efficiency in transporting and storing the food increases. The simplest method of drying with solar energy is to spread the agricultural products to the exhibition places and dry them outdoors. In this study, a cabinet type dryer was designed and apricot dried in this dryer. Drying process was carried out in the three type cabinet with solar energy. The results of the experimental studies with three type drying cabinet were compared. Drying control was done by weighing the samples for a certain period of time. The control of the air circulating in the cabinets is determined by the relative humidity and temperature values. In the study, it was shown that drying in the cabinet supported with air collector was much faster than others.

Kabin Tipi Kurutucularda Güneş Enerjisi ile Kayısı Kurutulması

Öz

Gıdaların güvenli bir şekilde saklanması için en önemli tekniklerden biri kurutmadır. Bu amaçla gıda muhafazasında farklı kurutma yöntemleri geliştirilmiş ve kullanılmıştır. Uzun süreli depolamada gıda maddelerine uygulanan kurutmanın temel amacı bozulmayı önlemektir. Böylece ürünün nemi azaltılır ve mikrobiyal üreme önlenebilir. Kurutma işlemi ile ürünün hacmi azaldığında, gıdanın taşınması ve depolanmasındaki verim artar. Güneş enerjisi ile kurutmanın en basit yöntemi, tarım ürünlerini açık alanlara yaymak ve açık havada kurutmaktır. Bu çalışmada, kabin tipi bir kurutucu tasarlanmış ve bu kurutucuda kayısı kurutulmuştur. Kurutma işlemi güneş enerjisi ile üç tip kabinde gerçekleştirilmiştir. Üç tip kurutma kabini ile yapılan deneysel çalışmaların sonuçları karşılaştırılmıştır. Numuneler belirli bir süre tartılarak kurutma kontrolü yapılmıştır. Kabin içindeki havanın bağıl nem ve sıcaklık değerleri ile ölçülmüştür. Çalışmada hava kollektörü ile desteklenen kabinde kurutmanın diğerlerine göre çok daha hızlı olduğu gösterilmiştir.
