Dünyada enerjinin %80’nini kömür, doğalgaz ve petrol gibi fosil yakıtları ile karşılanmaktadır. Yenilenebilir enerji kaynaklarından biyoyakıtlar fosil yakıtlara alternatif olarak kabul edilmektedir. Biyoyakıt üretiminin fosil yakıtlara oranla maliyetlerinin daha yüksek olması kurutma teknolojilerinin geliştirilmesi önem arz etmektedir. Önemli biyoyakıtlardan biri olan, mısır, kolza tohumu vb. alternatifleri göz önünde bulundurulduğunda şeker pancarının biyoyakıt için en verimli hammadde olması ile birlikte daha ekonomik olduğu bildirilmektedir. Şeker pancarı posası’nın biyoyakıt elde edilmesinde kullanımı çevresel atığın değerlendirilmesi açısından önemlidir. Bu çalışmada amaç, bantlı kurutucuda şeker pancarı posası’nın (ortalama nem içeriği %85 y.b) kurutma karakteristiğinin incelenmesidir. Şeker pancarı posası için 85˚C sıcaklıkta 20 cm bant kalınlık deney koşullarında gerçekleştirilmiştir. Ürün ilk nem içeriği %85 (yb) ‘den %14 (yb) neme kadar kurutulmuştur. Ürün nem içeriğin değişimi ile nem oranın değişiminin zaman bağlı olarak incelediğimizde kurutmanın 40 dk’ya kadar hızlı daha sonra yavaşladığı görülmüştür. Kuruma kızının nem içeriğine bağlı olarak incelediğimizde ürün kuruma başladığında üründen nemin uzlaşması yavaş olduğu çıkarılırmıştır. Bantlı kurutucuda şeker pancarı küspesinin kurutulmasında özgül enerji tüketimi hesaplamaları yapılmış ve 2,06 kWh/kg olarak bulunmuştur. Çalışma ile atıktan türetilmiş yakıt çalışmalarına katkı sağlaması hedeflenmektedir.

Experimental Investigation of Drying Characteristics of Sugar Beet Pulp in Belt Dryer

Öz

In the world, 80% of the energy is met by fossil fuels such as coal, natural gas and oil. Biofuels from renewable energy sources are accepted as an alternative to fossil fuels. The fact that the cost of biofuel production is higher than fossil fuels is important for the development of drying technologies. One of the important biofuels, corn, rapeseed etc. considering the alternatives, it is reported that sugar beet is the most efficient raw material for biofuel and is more economical. The use of sugar beet pulp in the production of biofuel is important for the evaluation of environmental waste. The aim of this study is to examine the drying characteristics of sugar beet pulp (average moisture content 85% w.b.) in a belt dryer. The product was dried from initial moisture content of 85% (wb) to 14% (wb). When we examine the change in moisture content of the product and the change in moisture content depending on time, it has been observed that drying is fast up to 40 minutes and then slowed down. When we examined the drying based on the moisture content of the daughter, it was found that when the product started to dry, the moisture reconciliation of the product was slow. The specific energy consumption calculations were made for the drying of sugar beet pulp in the belt dryer and it was found to be 2.06 kWh/kg. The study of the study is to contribute to waste-derived fuel studies.
