Grain drying is a vital operation in preparing finished grain products such as flour, drinks, confectioneries and infant food. The grain drying kinetics is governed by the heat and mass transfer process between the grain and the environment. Incomplete, improper and over-drying are crucial to the grain quality and negatively influence the acceptance of the grain by the consumers. Dried grain moisture content is a critical factor for developing grain drying systems and selecting optimal performance by researchers and the grain processing industry. Many grain drying technologies such as fluidised bed dryers, fixed bed dryers, infrared dryers, microwave dryers, vacuum dryers and freeze dryers have been used in recent years. To improve the drying process of grain, researchers have combined some drying technologies such as microwave + hot air, infrared + hot air and microwave + a fluidised bed dryer. Also, they introduce some treatments such as ultrasound dielectric and dehumidification. These methods enhance the dryer performance, such as higher moisture removal, reduced processing time, higher energy efficiency and nutrient retention. Therefore, this review focused on the drying conditions, time, energy consumption, nutrient retention and cost associated with the reduction of moisture content in grain to a suitable safe level for further processing and storage.

“…[3] Artificial intelligence techniques are also found in drying. [6] They are used for process variable prediction [10][12] [15], process control [9][11] [13] or for soft sensors [14]. Artificial neural networks (ANN) are sucsefully applied on all these fiels on their own, or combined with other AI or conventional techniques.…”

We compared a semi empirical and an empirical model. The empirical model is a multilayer ANN. The semi empirical model is a custom multilayer ANN. It is a structured model, and we define the structure by hand before the training of the network. The influence of the neuron numbers on the accuracy of the models was also investigated by statistical approach.We found that the custom multilayer ANNs developed like this, are suitable for modelling the drying process of agricultural materials. They also provide the ability to improve the applicability of the empirical models. Furthermore, the semi empirical model has a higher sensitivity on neuron number applied.

“…Güneş radyasyonu, hava sıcaklığı, akış ve üretilen enerji arasındaki ilişkinin termodinamik analizi yapılıp, verimlilik, üretilen enerji ve ayarlanan sıcaklık arasındaki ilişki analiz edilmiştir. Ayrıca, hava akımı, güneş radyasyonu ve dış hava sıcaklığına bağlı olarak güneş kolektörlerinden çıkış havası sıcaklığını tahmin etmek için yapay bir sinir ağı modeli kullanılmıştır [9]. Bir diğer çalışmada, kerestenin kızılötesi kurutma özellikleri araştırılmaktadır.…”

ÖzYapılan çalışmada kayısı kurutmak için düz ve hapsedici yüzeyli emici plakalara sahip kurutma sistemleri dizayn edilip imalatı yapıldıktan sonra, performansları mukayese edilmiştir. Deneylerde 4-5 mm kalınlığında dilimlenmiş, yaş bazda %76 neme sahip kayısılar kullanılmıştır. Deneylerde 30 dakikalık aralıklarla ölçümler yapılmış ve takip eden ölçümler arasındaki farkın %1'den az olduğu sonuçlarda deney sonlandırılmıştır. Kurutma işlemi, 2,5 , 3,0 ve 3,5 m/s kurutma havası hızlarında gerçekleştirilmiştir. Yapılan deneyler sonucunda, düz yüzeyli kurutma sisteminin kurutma odası ortalama sıcaklığı 45,96 °C iken hapsedici yüzeylinin kurutma odası ortalama sıcaklığı 49,04 °C olarak tespit edilmiştir. Düz yüzeyli kurutma sisteminde tüm hızlarda kurutma süresi 390 dk sürerken hapsedici yüzeyli kurutma sisteminde 2,5 ve 3,0 m/s hızlarında kurutma süresi 330 dk, 3,5 m/s hızda 300 dk sürmüştür. Hapsedici yüzeyli kurutma sisteminin, düz yüzeyli kurutma sistemine göre 2,5 ve 3,0 m/s hızlarda 60 dk, 3,5 m/s hızda 90 dk daha kısa sürede kurutma işlemini gerçekleştirdiği sonucuna varılmıştır. AbstractIn this study, drying systems with flat and incarcerating surface absorbent plates were designed and manufactured for drying apricots, then their performances were compared. Experiments were carried out with slices 4-5 mm thick, with 76% moisture on wet basis. The measurements were made at 30 minute intervals in the experiments and the experiment was terminated when the difference between the following measurements was less than 1%. The drying process was carried out at 2,5, 3,0 and 3,5 m/s drying air velocities. As a result of the experiments, while the average temperature of the drying chamber of the flat surface drying system was found to be 45,96 ° C, the drying chamber average temperature of the incarcerating surface was found to be 49,04 ° C. In the flat surface drying system, the drying time lasts 390 minutes at all speeds, while the drying time of incarcerating surface drying system is 330 minutes at 3,2 and 3,0 m/s and 300 minutes at 3,5 m/s. It has been concluded that the incarcerating surface drying system performs drying at a speed of 2,5 and 3,0 m/s for 60 minutes and 3,5 m/s for 90 minutes shorter than the flat surface drying system.
