Influence of Blade Number and Blade Cutting Velocity on the Performance of Cassava Stems Chopping Unit for Producing Pellet Fuel
Keywords:
Blades number, Blade cutting velocity, Cassava stemsAbstract
The objective of this study was to determine the effect of blades number set and linear velocity on the performance of a chopping unit for producing pelleted fuel. The Kasetsart 50 various cassava stem with an average moisture content of 9.85 % (wet basis), the feed rate was controlled by 130 kg/hr. Three number of blades sets; 2, 3 and 4 blades and five levels of the cutting blade velocity of 4.12, 5.03, 5.95, 6.80 and 7.78 m/s were studied The result showed that the chopping unit with 2 blades number and cutting blade linear velocity of 5.03 m/s had capable of working 115.30 kg/hr, power consumption 1.28 kW, specific energy 11.06 W∙hr/kg and 69.6 % distribution of the cassava sized 1-10 mm., respectively
