Effect of Shelling Clearances and Shelling Shaft Speeds on Performance of Sacha Inchi Shelling Unit
Keywords:
Shelling clearances, Shelling shaft speeds, Sacha Inchi shelling unitAbstract
This project aimed to find out proper operating factors of disc-typed Sacha inchi shelling unit. Performance was evaluated from shelling percentage, broken seed percentage, working capacity and specific energy consumption. Sacha Inchi moisture content of 4.61% (w.b.) were used in this study, feed rate was controlled at 290 kg/h, tested 3 difference shelling clearances of 13, 15 and 17 mm with difference shelling shaft speeds of 200, 250 and 300 rpm. The result show that shelling clearances, shelling shaft speeds and interaction of shelling clearances with shelling shaft speeds significantly impact all indicator. The shelling clearance of 15 mm with shelling shaft speeds about 250-300 rpm are suitable operating factors of the shelling unit, providing shelling percentage, broken seed, working capacity and specific energy consumption about 95.70-96.94%, 6.52-7.80 %, 245.40-255.78 kg/h and 3.93-3.95 W-h/kg, respectively.
