Tarımsal ürünlerin dayanımını artırma gayretlerinden birisi de kurutmadır. Ürünlerin kuruma karakteristiklerini incelemek için yapılan çalışmalarda kütle oldukça önemlidir. Bu çalışmada, kurutma denemeleri için tasarlanmış 3 numune kabına sahip, sıcak hava ile çalışan bir deneysel kurutucu sisteme otomatik tartım sistemi yapılmıştır. Kurutma makinelerinde kapların ağırlıklarını ölçmek için operatör sürekli belirli zaman aralıklarında kapları yerinden çıkartarak, tartıp tekrar yerine koymaktadır. Kurutma süresi, ürün çeşidi ve miktarına göre 72 saate kadar sürebilmektedir. Bu çalışmada, ürünlerin kütle kaybını ölçmedeki zorluklara çözüm getirmek amacıyla bir tartım otomasyonu gerçekleştirilmiştir. Üç hazneli kurutucu için üç adet yük hücresi kullanılarak ürünlerin kütlesi istenen zaman aralıklarında anlık olarak ölçülmüştür. Bu çalışmada Arduino Mega, HX711 24 bit ADC kartı ve kullanıcı ile etkileşim bileşenlerine sahip Nextion ekran kullanılmıştır. Askı tip yükleri ölçmede sıklıkla kullanılan S-tipi yük hücreleri yerine çubuk şeklinde platform tipi yük hücreleri kullanılmıştır. Daha ucuz olan platform tipi yük hücreleri, hazırlanan aparatlarla S tipi yük hücresine dönüştürülmüştür. Bu sayede platform tipi yük hücrelerinden daha duyarlı ve ucuz birer S tipi yük hücreleri elde edilmiştir. Yapılan testlerde ölçmeye ait önemli parametreler elde edilerek sistemin başarımı kanıtlanmıştır.

One of the efforts to increase the strength of agricultural products is drying. Mass is very important in studies to examine the drying characteristics of products. In this study, an automatic weighing system was built on an experimental dryer system working with hot air with 3 sample containers designed for drying trials. In order to measure the weight of the containers in the drying machines, the operator removes the containers at certain time intervals, weighs them and puts them back into their place. Drying time takes up to 72 hours depending on the product type and quantity. In this study, a weighing automation was implemented in order to solve the difficulties in measuring the mass loss of products. By using a separate load cell for each container of the dryer, the mass of the test materials was measured instantaneously at the desired time intervals. In this study, Arduino Mega, HX711 24 bit ADC board and Nextion display with user interaction components are used. Instead of S-type load cells, which are frequently used to measure tensile forces, rod-shaped platform type load cells are used. The cheaper platform type load cells were transformed into S type load cells with the prepared apparatus. In this way, S-type load cells which are more sensitive and cheaper than platform type load cells were obtained. The performance of the system has been proven by obtaining important parameters of measurement in the tests.
