Abstract

Objective: This research investigates the pelletizing performance of the machine used to process poultry litter. Fresh poultry litter poses challenges due to its high moisture content and volume per unit weight. Handling large volumes at low density over long distances is both difficult and expensive.The objective of this study is to employ a simple machine to transform poultry litter into the desired shape and volume weight, thereby improving storage, transportation, and off-site utilization.
Material and Methods: The research aims to assess the impact of five different moisture content levels (11%, 17%, 26%, 34%, and 47% d.b.), four die diameters (4 mm, 6 mm, 8 mm, and 10 mm), and three auger speeds (1.2 m/s, 1.8 m/s, and 2.4 m s-1) on pelletizing efficiency (%), broken pellets (%), and pelletizing capacity (kg h-1).
Results: The results indicate that optimal pelletizing efficiency (%) and minimum broken pellet percentage (%) were achieved at a moisture content of 26%, an auger speed of 2.4 m s-1, and a die diameter of 4 mm. Maximum pelletizing capacity (kg h=1) was attained with a moisture content of 47%, screw auger speed of 2.4 m s-1, and a die diameter of 10 mm.
Conclusion: Therefore, it is recommended to operate the simple machine at an auger speed of 2.4 m s-1 for optimum results.

Kümes hayvanı altlığı peletleme işleminde makine performansı

Abstract

Amaç: Bu araştırma, kümes hayvanı gübrelerini işlemek için kullanılan makinelerin peletleme performansını araştırmaktadır. Taze kümes hayvanı altlığı, yüksek nem içeriği ve birim ağırlık başına hacmi nedeniyle zorluklara neden olur. Büyük hacimlerin düşük yoğunlukta uzun mesafelerde taşınması hem zor hem de pahalıdır. Bu çalışmanın amacı, kümes hayvanı altlığını istenen şekil ve Hacim ağırlığı kazandırmak için dönüştürmek için basit bir makine kullanarak. depolama, taşıma ve saha dışı kullanımı iyileştirmektir.
Materyal ve Yöntem: Ayrıca araştırmada, beş farklı nem seviyesi (%11, %17, %26, %34 ve %47 d.b.), peletleme diskinin dِrt farklı delik çapı (4 mm, 6 mm, 8 mm ve 10 mm) ve üç farklı helezon (vida) (1,2 m s-1, 1,8 m s-1 ve 2,4 m s-1) hızının peletleme verimliliği (%), kırık peletler (%) ve peletleme kapasitesine (kg h-1) etkisi incelenmiştir.
Araştırma Bulguları: Sonuçlar, %26'lık bir nem içeriğinde, helezon vidası hızı ve peletleme diskinin 10 mm delik çapında bir peletleme diski delik çapı çapında optimum peletleme verimliliğine (%) ve minimum kırık pelet oranı (%) ulaşıldığını göstermektedir. Maksimum peletleme kapasitesine (kg h-1) %47 nem içeriği, 2,4 ms-1 vida hızı ve 10 mm peletleme diski delik çapı çapıyla ulaşılmıştır.
Sonuç: Bu nedenle, optimum sonuçlar için peletleme makinası 2,4 ms-1 vida hızında çalıştırılması önerilir.
