Performance Test of Various Teeth Diameter of Cylinder Type Sago Rasping Machine

Traditional method of sago starch extraction was a time and labor intensive process. The most laborious stage is pith disintegration which done by using hammer-like tools called pounder. However, the use rasping machine to disintegrate saving energy significantly. objective this study investigate effect teeth diameter cylinder rotation speed on performance type machine. In experiment, four variations i.e. 3mm, 4 mm, 5 mm 6 three levels 1500 rpm, 2000 rpm 2500 were examined. Results showed that both significantly affect capacity. Likewise also percentage losses in waste. Meanwhile, interaction two factors have no significant loss highest obtained at condition 3 with rpm. (a) capacity 2282 kg h-1, (b) 33.02 %, (wb), (c) waste 8.77 %.
