Selected Engineering Properties Of Tiger Nut As A Function Of Moisture Content And Variety, Ahmet İnce, Kubi̇lay Kazim Vursavuş, Yasemi̇n Vurarak, Pinar Çubukcu, Meli̇h Yavuz Çevi̇k
Turkish Journal of Agriculture and Forestry
Some physical and mechanical properties of two tiger nut varieties (Sarışeker and Balyumru) were determined at four moisture contents. Physical properties including length, width, thickness, geometric mean diameter, mass, 1000-tuber mass, bulk density, tuber density, surface area, terminal velocity, angle of repose, porosity, and friction coefficient were affected by moisture content at a 1% probability level, excluding sphericity. All parameters decreased with a decrease in moisture content except tuber density, porosity, and firmness. Variety only had a statistically significant effect on width, geometric mean diameter surface area, and terminal velocity at different probability levels. Force, deformation, firmness, energy absorbed, and …

The effect of chip size on hemicellulose extraction of wood and technological properties of flakeboard were investigated. Three different sizes of wood chips were treated with hot water in a digester at 170 °C for 90 min. After hydrothermal treatment, the wood chips were washed with water and then dried in a dryer. Flakes were produced from control and treated chips using a flaker. Flakeboards were produced from the flakes using urea-formaldehyde resin. The results showed that chip size had a significant effect on the chemical properties of hydrothermally treated wood under pressure in hot water. As chip size was …
